Version 0.8.13

- Internal changes:

* Adjust for apt 1.9.11

pkgDPkgPM should not be used directly, use _system->CreatePM()
    instead; also compare map_pointer in cache against new
    MapPointer() method instead of Index().

(Patch by Julian Andres Klode; from the 0.8.12-2 upload; Closes: #953306)

* Handle _error becoming a smart pointer thingy

This should be fixed nicer in apt, so that we can use _error again
    somehow, as _GetErrorObj() is not really part of the API (but the
    ABI).

(Patch by Julian Andres Klode; from the 0.8.12-3 upload)

* Switch from libparse-debianchangelog-perl to libdpkg-perl

The former was merged into the latter some time ago, with the main
    difference being the lack of some of the output formats that are not
    being used by aptitude.

This seems to have been attempted in the past, but was reverted due to
    performance problems. The performance from current libdpkg-perl should
    be comparable.

We use the perl module directly via a new aptitude-changelog-parser
    wrapper to avoid pulling dpkg-dev and its dependencies. This new
    wrapper will also make sure the module is available before proceeding.

(Patch by Guillem Jover; Closes: #934135)

* Rename README to README.DOCUMENTATION.

[2019-08-25]
Version 0.8.12

- New features:

* Permit to retrieve changelogs of packages from Debian Ports repositories.

* Adapt for changes in apt 1.9, like addressing deprecation and API changes.

Thanks to Julian Andres Klode.

- Bug fixes:

* Adapt code to adapt to change of behaviour in Boost.MultiIndex library, and
    so we can start using Boost >= 1.66, 1.67 is about to become the default in
    Debian unstable.

Thanks to Julian Andres Klode.

* Fix crashes when Label of a repository is empty (Closes: #907436)

* Fix changelog downloads

* Read the correct number of elements in
    pkg_item::pkg_columnizer::init_formatting() -- it was ignoring the last
    element, reading only 25 out of 26.

- Internal changes:

* Subsitute readdir_r() by readdir(), the former is deprecated.

src/generic/util/dirent_safe.h was removed due to being unnecessary after
    this change.

* Use APT::PrettyDep(cache, dep) to avoid warnings about deprecation of
    dumping dep directly to std::ostream

* Avoid deprecation warning by adding second parameter in TimeRFC1123()
    invocation in download_queue.cc.

Parameter set to "false" following code in apt's
    pkgAcqIndex::Custom600Headers().

* Fix for missing "#include <vector>" (necessary for upcoming change in
    cwidget)

[2018-07-29]
Version 0.8.11

- New features:

* Add search term for release label (?label) (Closes: #892983)
    by Tomas Pospisek <tpo_deb@sourcepole.ch>

- Documentation:

* Change en/README_encoding to use utf-8 as all the other languages, instead
    of iso-8859-1

- Internal changes:

* Use MKDIR_P instead of MKINSTALLDIRS in the building system, the latter was
    lost when m4/gettext.m4 was removed, and it was deprecated anyway.

* Pass "-no-home" to elinks when creating text files from HTML, to avoid the
    annoying errors when creating the localised documentation (with "terminal
    beep" included):

"ERROR at home.c:156: Unable to find or create ELinks config
    directory. Please check if you have $HOME variable set correctly and if you
    have write permission to your home directory."

* Use elinks only if available (similar to po4a, rsvg-convert, etc.)

* Switch to several std:: facilities from C++17's instead of Boost
    - std::filesystem instead of boost::filesystem
    - std::optional instead of boost::optional

* Fixes needed by GCC-8 and more strict versions of the library

- Translation updates:

* zh_CN.po: Simplified Chinese translation by Boyuan Yang (Closes: #885916)

* ru.po: Russian translation by Lev Lamberov (Closes: #893027)

* Russian documentation translation by Lev Lamberov (Closes: #893028)

[2017-11-15]
Version 0.8.10

- User visible changes:

* [Guillem Jover] Update section descriptions: Add "golang". Remove
    long-obsolete "non-US".

- Bug fixes:

* Restore ability to download changelogs with recent libapt (Closes: #881422)

There were changes in the backend of downloads of changelogs, so the URI can
    be store:// instead of gzip:// since (lib)apt 1.2, and has to be since in
    recent uploads.  So it was just switched to use store:// unconditionally,
    backporting to Jessie at this point is not high in priority...

- Internal changes:

* Remove m4/ with embedded copies of building-system helpers.  The debian part
    of the package will depend on autoconf-archive to provide those needed.

[2017-08-19]
Version 0.8.9

- Bug fixes:

* Fix crash due to wrong string pointer being printed (Closes: #865346)

* Fix compilation error with GCC 7 (Closes: #853316)

In a conversion involving an "operator string()", it seems that the code
    gets confused with the available ABI of std::string, similarly to what had
    happened with the ABI change of GCC-5 (but this is not supposed to happen in
    this new release).  The error was:

.../generic/apt/download_update_manager.cc:133:
        undefined reference to `URI::operator std::__cxx11::basic_string<char,
        std::char_traits<char>, std::allocator<char> >()'

[2017-06-11]
Version 0.8.8

- User visible changes:

* Avoid spurious warnings about unused code paths (Closes: #863755)

- Documentation improvements:

* Replace minimal example for configuring resolver hints with a full
    example. (Closes: #702565, part 1)

* Document keywords "maximum" and "minimum" for cost levels.
    (Closes: #702565, part 2)

* Mention in the man page that a tilde character in front of an
    order keyword reverses the order. (Closes: #814038)

[2017-04-18]
Version 0.8.7

- User visible changes:

* Warn about invalid locales (Closes: #859907)

- Bug fixes:

* Preserve auto-installed flag with hold/unhold/keep operations
    (Closes: #843536)

* [cmdline] Fix extreme slowness of keep-all (Closes: #842707)

Every change of marking the package to "keep" was triggering a reevaluation
    in aptitudeDepCache::end_action_group() of what had changed ("mark and sweep",
    duplicate of cache, triggers of packages state changes... etc), for every
    package.

* Avoid problems or improve response in problems related to reinstalling
    (Closes: #851901)

Improvements to deal with several problems that sometimes appear when
    reinstalling or acting on scheduled reinstall actions, due to the versions
    disappearing from the repositories.

* [cmdline] Failing to apply actions are not fatal with -f /
    Aptitude::CmdLine::Fix-Broken (Closes: #835372)

The behaviour of refusing to continue when there are errors happens since
    the change "[cmdline] Abort with Failure when actions cannot be taken
    (Closes: #121313, #430392, #445034, #498239, #576212, #639789, #798320)",
    but it's not an optimal solution for automatic installers like FAI, so this
    is a way to revert to the old behaviour.

- Internal changes:

* new method is_version_available(), to check if the given version of a
    package is available (to check availability e.g. for reinstalls)

- Translation updates:

* Italian documentation translation by Beatrice Torracca (Closes: #858784)

[2017-03-05]
Version 0.8.6

- User visible changes:

* [cmdline] Better message when there are no deb-src in sources.list
    (Closes: #841875)

- Bug fixes:

* Use a more strict mask for comparison of dependency operators, thanks to
    Aaron M. Ucko for the initial patch (Closes: #836567, #837946, #849370)

Recently apt started to use more values in an enum used for dependency
    operator comparisons, which causes some problems because aptitude's code
    from many years ago, which did not expect new values.

Using a stricter mask to capture only the operators, as per the
    documentation of the enum (lower 4 bits).

* Fix reading tag and their classification in subtrees (Closes: #853037)

Newline characters were added to the last tag (or the only one), and it
    caused extra problems like classifying the tag in their own subtree due to
    the new-line mismatch in the tag name.

* Fix misdetection of auto-installed packages from apt
    (Closes: #831858, #841347)

Version 0.8.4

- User visible changes:

* Updated section list and added descriptions. Thanks Josh Triplett!
    (Closes: #847530)

* Support for Build-Depends/Conflicts-Arch, by David Kalnischkies
    (Closes: #843789)

- Bug fixes:

* [curses] Do not fail immediately and attempt to continue when some package
    lists cannot be updated (Closes: #834790)

The bug, in which the update of package lists stopped and the interface was
    left at the "Loading cache" stage indefinitely, seems to be due to changes
    in behaviour of apt or some strange interaction, because the relevant
    sections of aptitude have not changed in a long time.

This is fixed now by not being strict with this kind of errors (to cope with
    what seems to be a new behaviour from libapt -- to not report that the
    update can proceed)... Hopefully this change will not create other problems.

- Internal changes:

* Support recent versions of googletest and google-mock, change of paths:
    /usr/src/gtest -> /usr/src/googletest/googletest
    /usr/src/gmock -> /usr/src/googletest/googlmock

[2016-08-07]
Version 0.8.3

- User visible changes:

* [cmdline] Commands "markauto", "unmarkauto", "hold", "unhold", "keep",
    "keep-all" and "forbid-version" now work independently of other action
    commands and they will not try to go ahead with pre-scheduled actions
    (Closes: #142699, #567079, #764299)

This is similar to how "forget-new" or user-tag related commands worked, and
    the fact that they started to install or remove packages caused confusion.

- Bug fixes:

* [curses] Use single-line for "forget-new" dialog when using minibuf prompts
    (Closes: #832363)

* [cmdline] "download", "source" and others provided by a thin wrapper over
    apt tools now accept "-t" and other options (Closes: #832320)

* [cmdline] Document "source" and "showsrc" in --help (Closes: #833584)

* [cmdline] Saying 'n' to a solution jumps to the end of the generated
    solutions and tries to generate a new one (Closes: #832907)

This reverts b41db12f ("Rejecting a solution advances to the next one only")
    but also improves the description.

* Fix code preventing to save package selection states to dpkg
    (Closes: #825866, #833588)

- Internal changes:

* Create on_apt_errors_print_and_die(), for the common case of checking for
    errors from apt, printing them on the screen and exiting immediately with an
    error code

* cmdline_util: Add get_packages_from_set_of_strings(), to help parsing
    package names and resolve patterns from the command line (using the
    lower-level get_packages_from_string())

[2016-07-23]
Version 0.8.2

- New features:

* [cmdline] New commands "showsrc" and "source"
    (Closes: #243412, #403372, #403631)

Provided by a thin wrapper over apt tools.

* [cmdline] "forget-new" accepts package names and pattern arguments

Addresses part of #421043 (and merged).

* [curses] "forget-new" accepts package names and pattern arguments
    (Closes: #421043)

- Bug fixes:

* [curses] Apply solution ('!') guarded against crash when there are no
    solutions (Closes: #823734)

* [cmdline] Command "download" now provided by a thin wrapper over apt tools
    (Closes: #431568)

This command from aptitude did not provide verification of downloaded files.

* [curses] Flat view changed to honour ::Pkg-Display-Limit if exists
    (Closes: #814037)

* Fix crash caused in infer_reason.cc for pkg_unused_remove (Closes: #824441)

Introduced in some difficult to reproduce conditions by fix for "Enhance
    infer_reason() to explain more cases of pkg_unused_remove", bug #266061, in
    0.8.

* [cmdline] Fix for code that failed to fetch the changelog for source
    packages.  Thanks Emmanouil Maroudas for the fix.  (Closes: #827133)

- User visible changes:

* [curses] Change TUI message after "pressing 'q' and then 'Enter'"
    to no more mention "shutting down". Use "quitting" instead.

- Internal changes:

* aptcache.{h,cc}: Split aptitudeDepCache::forget_new() in two parts, one to
    unmark as 'new' a given set of PkgIterators, another unmarking all.

* cmdline_util: Add get_packages_from_string(), to help parsing package names
    and resolve patterns in the command line

- Documentation:

* Guide/User's Manual:

* Enhance the documentation of the use of "architecture specification" for
      ?architecture search pattern arguments, instead of simple string matches
      (Closes: #823927)

The commit d78de1ea in 0.6.8.2-1 had the side effect that the strings for
      the arch search pattern are no longer treated as simple "string patterns"
      as it happened before, when architectures were matched with partial
      strings (as it does with package names, etc.).

In the case of TUI with interactive search enabled, it means that packages
      do not match until the arch-specification is complete/valid, triggering
      "beeps" meaning that no packaged match.

* Add clarification for ?any-version search pattern (Closes: #691531)

* manpage:

* Remove outdated exceptions of -t/--target-release for "changelog",
      "download" and "show" (Closes: #693684, #821866)

* Describe aptitude-[create|run]-state-bundle as for internal use only
      (Closes: #521190)

- Translation updates:

* Russian documentation translation by Lev Lamberov (Closes: #829681)

[2016-05-05]
Version 0.8.1

- Bug fixes:

* Install Essential or Required packages with the commands "full-upgrade"
    (command line) and MarkUpgradable ('U' in the curses interface)
    (Closes: #555896, #757028)

* Do not prevent to remove/purge aptitude if already removed or purged
    (Closes: #822331)

E.g. aptitude:i386 in amd64 with multiarch.

* [curses] Indent section descriptions in subtrees (Closes: #103416)

Not the same as creating a column, but same effect.

* Invoke the resolver for unfulfilled Recommends only once (Closes: #822329)

After the fix for #819636, the resolver was invoked after every action taken
    (in curses mode) to see if there were any unfulfilled dependencies.  This is
    too slow for some people/systems, so this is now only invoked will full
    check of dependencies (Recommends / "soft deps") before the final action.

* [curses] Be more verbose when quitting after dpkg actions (Closes: #822560)

This is related to the fix in the previous version for #246672.

Make curses windows visible when restoring (instead of staying blank) to
    show message of "Updating state and shutting down", and make some
    improvements to speed up shut down.

The optimisation is achieved through a global variable shutdown_in_progress
    that apt_load_cache() pays attention to, to e.g. avoid re-loading tags.
    This mechanism is not very elegant, but:

a) we cannot quit directly (we need to save the state after package
       actions were taken, for example), and

b) untangling the rest of the shutdown process is very difficult, with the
       state of the code having grown organically for years without taking this
       into account (it would need significant rewrites); and duplicating code
       for the cases when we quit and we continue is not very good either

[2016-04-20]
Version 0.8

- New features:

* Detect and suggest solutions when pkgstates is corrupt (Closes: #405506)

* Allow to choose between localized logs or not (default is not) with the
    option ::Localized-Log (Closes: #357828, #596221)

* [curses] Left/Right arrow keys collapse/expand one level of the subtree, and
    when in a package item (row) Left jumps to "parent"
    (Closes: #157984, #241945, #415449)

The solution is a bit "hacky", because for example for the left arrow in the
    package item to jump to its parent, the pkg_item objects have to capture
    events of some keybinding ("collapse") and re-inject the event as "parent".
    The direct route, which would be to add "left" as an alias of "Parent",
    doesn't work in this case, because some elements using "left" for other
    purposes would be confused and would interpret it as "Parent".

Maybe there is another way to achieve this more cleanly if it's possible to
    assign bindings like "Parent" specific to e.g. tree items (pkg_items derive
    from that), but even if cwidget allows for this, it seems to be quite
    complicated to achieve it.

* [curses] Be able to Quit after dpkg run (Closes: #246672)

The current implementation seems to work, but the handling of these issues
    is a bit brittle and with lots of circular dependencies, with signals and
    events happening everywhere.  E.g view (cwidget objects) being reloaded
    automatically when cache is reloaded, while cwidget is supended for dpkg
    run.  The initial events trigger further updates and triggers using cwidget
    objects and other structures, sometimes depending on different options being
    enabled or how the curses mode was launched (e.g. "visual preview", or
    "solution screen").

In any case, the cache needs to be reloaded (and with it, state saved to
    disk) to perform some updates/cleanup after dpkg runs, like resetting
    "reinstall" state when done (the "save pending reinstall" was implemented in
    this version), or unmarking upgraded packages as needing upgrade after the
    version has been upgraded to the desired one (bug fixed in this version,
    when aptitude was not acknowledging the "upgrade" as having taken place, and
    still marking it as update in the next runs).

Presumably all of these complications are why this hand't been implemented
    before, in all the intervening years.

Still I thought that it was worth to implement it now because it will now at
    least save the user/system from spending time in some of the curses actions,
    save a few extra keystrokes, and with it a few seconds (specially in slower
    systems) having to keep an eye just for quitting.

- Bug fixes:

* ~E pattern now returns packages with Essential only (Closes: #548505)

apt marks itsef as Essential, so this doesn't change much some aspects of
    the bug report.

* Detect as "Security Upgrades" when site matches security.*.d.o
    (Closes: #328620)

Previously it was only matching "security.debian.org", not accounting for
    mirrors like "security.eu.debian.org".

* Allow to run in dumb terminals when not requiring curses preview or solution
    screen (Closes: #817276)

The bug fixing #317928 forbade some uses which are not problematic.  Also
    added a few more checks to also forbid launching solution screens and
    previews from the command-line.

* "reinstall" planned action is now preserved across sessions, when becoming
    root or in the command line with --schedule-only (Closes: #255587, #785641)

After the successful reinstallation of this package (and probably other
    installations/upgrades/deletions/... in the same action), the package is
    unmarked for reinstallation.  There's no way to detect individually whether
    a package was reinstalled successfully, so if there is a failure in the
    whole set of actions, the package will still be marked for reinstallation
    even if the reinstallation itself has actually succeeded.  This is the best
    that we can do without significant complications (e.g. handling
    reinstallations in a package-per-package basis and separate from other
    actions, but this would be somewhat similar to going back to the current
    situation -- not treating it just as other actions).

It is unlikely that this is a big problem in the real world, though.
    Probably reinstallations are performed very frequently, and when they are,
    it's unlikely that they are bundled in conjunction with package actions such
    as big upgrades.

* Fix crash when invoking curses resolver from command line (Closes: #817776)

This fix is analog to the one for #816322, and previously to that the
    problems involving boost::flyweights.

* Update internal state for upgrades without target version after the action
    is performed (Closes: #721426)

This extends "Update internal state for upgrades/downgrades with target
    version after the action is performed (Closes: #787658, #714429)", by also
    trying to remove the "Upgrade: yes" line in pkgstates when the package has
    been upgraded to the candidate version (when a explicit version is not
    requested).

Otherwise the lines linger in "pkgstates" for longer than necessary, until
    it is updated due to other packages needing changes; with the side effect
    that if an "aptitude update" happens before the lines are removed, the
    packages are automatically marked for upgrade in subsequent aptitude
    sessions.

* [curses] Fix for miscalculated Download Size field (Closes: #817547)

After running dpkg run or under some other conditions (cache closed), the
    object storing fetch information did not get reset and updated correctly.

* Marking as keep, through ':' or other actions, clears Forbidden version

Uncovered investigating #615481.

* Fix cases where user tags operations did not apply (Closes: #819002)

This was caused by misuse of locks before the operation of saving the state
    file (pkgstates).

* Actions involving unfulfilled Recommends invoke the resolver
    (Closes: #819636)

With APT::Install-Recommends="true" (the default), actions resulting in
    unavailable Recommends (e.g., the recommended package is upgraded instead of
    remaining in the required version) invoke the resolver, for the user to take
    decision.

This is because now the resolver monitors situation when the
    PolicyBrokenCount is not zero, before it was only taken BrokenCount into
    account (it was the only count available when the code was set up).

* Enhance infer_reason() to explain more cases of pkg_unused_remove
    (Closes: #266061)

Enhance infer_reason() to explain more cases where package is removed
    because of automatically installed and unused (one case related to #819636).

The case related with #819636 is when the version of the depended package
    (the one for which we look the reason of removal) changes because e.g. it is
    upgraded, so maybe it doesn't fulfill the original dependency (for example
    because the package depending on it it depends on an exact or less-than
    version, as in the bug report).

The second case (#266061) was missing the explanation because it didn't take
    into account reverse-depends of virtual packages provided by the package
    being inspected.

- User visible changes:

* [cmdline] Output in dumb terminals, when there is no piping/redirection
    involved and even if ioctl doesn't work to get window size (e.g. inside
    emacs), will now use COLUMNS instead of the default very big default width

* Format string scapes for Source (%E->%e) and Architecture (%e->%E) swapped

This is for consistency while addressing #743769, while it's not too late
    (only a few releases in unstable since they were added).

* New short form "~e" for search term "?source-package" (Closes: #743769)

* [curses] Remove option to run "dpkg-reconfigure" on a given package
    (Closes: #680334, #686626, #738350)

Similar to "reportbug" recently removed, it was mostly an annoyance with
    several related bugs open, with others fixed in the recent past (#474876),
    was not integrated with the rest of actions -- no menu entry, would trigger
    an immediate without confirmation (sometimes by mistake) instead of a
    planned action, since it was immediate could not be saved as most/all
    actions are...

In addition, this is a relatively dangerous operation that should seldom be
    needed, and it's better if people run it run by hand rather than if they
    trigger it by mistake.

Lastly, as a curiosity and as telling of the typical evolution of the
    sofware features, the history of it is: Added in the version 0.2.3 released
    on 2001-07-11, with this comment: "You can now run dpkg-reconfigure from
    within aptitude (it's a silly feature, but it's also about 10 lines of
    code..)".  The original 10 lines of code are now 67 in pkg_item.cc, 1
    keybinding in defaults.cc, mentions in the documentation and all of the
    translations; needs to use different mechanisms for "su-to-root" permissions
    that it needs, there were at least 4 bugs involving the feature, and
    spending a few hours tracking all of this to finally remove it... so much
    for an innocent silly feature with only 10 lines of code :-)

* [cmdline] Solution screen for "Remove the following packages" shows version
    and suite

This is to make it more similar to the other cases shown, which include a
    version, as well as being able to deduce when a package is local / obsolete
    ("now") instead of being part of other suites.

E.g. it will show:

Remove the following packages:
      1)     libsdl1.2-dbg [1.2.15+dfsg1-2 (now)]

instead of the previous:

Remove the following packages:
      1)     libsdl1.2-dbg

- User visible changes (Resolver):

This subsection is to separate the (many) changes of the Resolver in this
  version from other changes.

When dealing with conflicts or when called when special options
  (--full-resolver in the command line), aptitude fires an internal resolver to
  try to address the resolution of conflicts caused by the requested action(s).
  This was created at a time when apt was not resolving very well the
  dist-upgrades and other actions, and long before Multi-Arch was implemented in
  Debian, so with time the gap between aptitude and others was smaller, often
  apt does a better job than aptitude, then unfavorable comparisons started to
  be made, and other problems started to appear in the implementation.

This is a very complicated piece of software, and it's very difficult to fully
  understand and reason about the consequences of deep changes.  As a heuristic
  system, the solutions that it gives are quite open (so it's better if it's
  guided towards desired solutions), and tweaks to the process can have
  unpredictable and undesired effects somewhere else.

That said, since in the last few years there were many complaints about the
  first solution offered being very often undesirable (removal of many
  packages), and (from most user's point of view) preferable solutions like
  upgrades being offered only after many removals, and keeps only offered as
  last resort; some changes were made to try to address these problems.

The main change that seems to have started this in the past was with #565867
  in 0.6.1.5 back in 2010 (but there are bugs open much older than that, so it's
  been a recurring problem):

+ [all] Changed the default resolver configuration so that removals
            and "safe" actions are grouped together.  Without this
            change, aptitude was being too conservative and failing to
            solve simple upgrades. (Closes: #565867)

The safe-upgrade resolver is unaffected by this change,
            since it uses explicit constraints to prevent removals from
            being installed.

In the comment of the bug report, the original developer says:

"In the 0.6 series, the aptitude resolver is a lot more conservative
     than it used to be, due to repeated complaints by users that it was
     removing too many packages in the first solution that was presented.
     It looks like maybe I overcompensated, though (this is not the first
     report along these lines).

The main difficulty in cases like this is getting the algorithm to
     properly balance removals with upgrades.  However, it looks like the
     old scoring system works just fine here."

This is still true now.  Hopefully after the changes in this version the
  balance is acceptable for most common actions when using aptitude, including
  day-to-day upgrades as well as occasional big upgrades between Debian
  releases.

Now onto the changes.  Executive summary:

* Changes to the order in which solutions are offered in conflict resolutions,
    so upgrades or keeps are preferred over removal of many packages

(Closes: #341963, #359171, #365644, #453935, #569315, #570377, #574132,
             #588202, #610845, #651410, #651947, #653284, #661678, #722211,
	     #798240)

A more detailed description of individual changes follows:

* Modify several resolver scores config variables

::ProblemResolver::RequiredScore was lower (4) than ImportantScore (5), even
    if it's in fact higher in the rank; while ExtraScore was -1, even if many
    regular package in current systems are priority "extra" -- they should not
    be penalised as "could we do without".  The new scores are:

::ProblemResolver::RequiredScore  = 8  (was: 4)
      ::ProblemResolver::ImportantScore = 4  (was: 5)
      ::ProblemResolver::StandardScore  = 2  (was: 3)
      ::ProblemResolver::OptionalScore  = 1
      ::ProblemResolver::ExtraScore     = 0  (was: -1)

* Add new score for removal of obsolete package and corresponding config
    variable ::ProblemResolver::RemoveObsoleteScore

Removal of obsolete packages is treated as positive (310) to allow for
    easier upgrades.  It has to counter at least the penalty to remove packages
    (currently -300).

* Add new score for partial solutions cancelling the removal of a package and
    corresponding config variable ::ProblemResolver::CancelRemovalScore

Resolver actions cancelling the removal (or purge) of a package requested to
    be removed/purged were not being penalised, now they are (default -300).

This was missing compared to penalisations for other actions like
    RemoveScore, when removing packages not marked for removal.  Now, solutions
    of the resolver cancelling explicitly requested removals are also penalised.

* Only add Preserve{Auto,Manual}Score if the packages are actually installed

Without this, the algorithm was assigning extra score +60 (default
    PreserveManualScore) for packages which remained uninstalled (were not to be
    installed) and when the user actually didn't select them manually -- even if
    the justification was "because it is the to-be-installed version of a
    manually installed package".

This caused for example that in amd64 with multi-arch 386 "Score: +60 for
    uno-libs3:i386 [UNINST] because it is the to-be-installed version of a
    manually installed package (..::PreserveManualScore)", and "Score: -20 for
    uno-libs3:i386 5.1.1-1 because it is a new install (..::InstallScore)", so
    installing the version rather than keep it uninstalled had comparatively a
    -80 disadvantage, 4 times worse than the penalty of installing the new
    package itself (which is already quite big).

At the same time, since PreserveAutoScore is 0, the package which was
    actually installed had "Score: +0 for uno-libs3:amd64 5.1.1-1 because it is
    the to-be-installed version of an automatically installed package
    (..::PreserveAutoScore)".

So this is now only applied to installed packages, to avoid these undesired
    effects.

* Change the default score of several ::ProblemResolver config variables

These are:

::StepScore to -10 (was +70)
      ::PreserveManualScore to +20 (was +60)
      ::UpgradeScore to +30 (was 0)

Long explanations:

1) ::StepScore to -10 (was +70)

Due to #418385 (back in 2007) it was raised from +10 to +70.  There were
    already complaints after the change about "removing way too much stuff on
    upgrades".

With positive numbers it gives extra score for exploring more and more steps
    in the problem space (more inclined to search "depth-first" in the graph),
    and the comparatively large score meant that this was offsetting the
    negative score of some generally undesired actions (e.g. removing packages
    which are otherwise fine), so the overall balance of taking more actions on
    packages was positive even if it meant removing many packages removed rather
    than upgrading only one.

(On a related note, RemoveObsoleteScore was added to consider removal of
    local/obsolete packages as positive, when e.g. doing dist-upgrades and
    leaving packages behind).

This played a big role in the problem (that appeared or became worse at some
    point a few years ago) of the first suggestions offered by the full resolver
    to be those removing many packages, rather than upgrading a single one or a
    few, or at least suggesting the one(s) causing the conflict (selected to be
    upgraded by the user) to be kept.

This has been tested in several bread-and-butter scenarios with
    a better outcome than the previous solutions (dist-upgrade, and upgrading
    packages that breaks others if not upgrading them --transitions,
    dependencies on same versions of the same source package, etc--).

It will of course have some side effects, and perhaps has to be reverted or
    further tweaked, but at least is an attempt to improve the general
    situation.

2) ::PreserveManualScore to +20 (was +60)

As explained in another point of this version in the changelog, this
    variable caused that the score for installing a new version was -20 plus +60
    bonus to keep the "manual" uninstalled version uninstalled.  This was
    changed to only have into account cases where packages are installed, but it
    affects still other cases in similar ways.

It also interacts badly with UpgradeScore, because if the score assigned to
    this variable is higher than the one in ::UpgradeScore, the package is
    preferred to be kept in the current versions than upgraded, and this used to
    cause big penalties for situations packages that need to be upgraded to the
    same versions.  Upgrading packages coming from the same source in lock-step
    is a typical case where packages have these strict dependencies with exact
    versions.

So it seems sensible to lower this score to something that might be more
    easily overcome by other package actions that are needed very often.

3) ::UpgradeScore to +30 (was 0)

Apart from the explanation in 2) (that this score should be higher than
    ::PreserveManualScore to have better suggestions in many common cases), it
    seems natural that upgrades are preferred to actions at 0 like Keep, since
    very often the purpose of launching package management tools like aptitude
    is to upgrade -- if there are upgrades available.

* Change the default value of ::ProblemResolver::Keep-All-Level config
    variable

::Keep-All-Level to 10000 (was 20000)

This cost level is assigned to solutions that cancel all the user's actions
    ("keep all").  A cost level that is lower is preferable in the "safety"
    mode, which is the default.  More information about Costs in the User's
    Manual documentation, section "Resolving package dependencies".

There are two levels which were lower (at 10000 both) than this one,
    Safe-Level and Remove-Level.  The first is for safe actions, the other one
    (also with 10000 in the last few years) is presumably to allow for packages
    to be removed when they become obsolete, chiefly in dist-upgrade situations.

Since several years ago, in cases where the full resolver had to kick in,
    the first suggestion for conflicts or unfulfilled dependencies was often to
    remove a lot of packages.  Part of the reason why this was preferred to
    upgrades or installations of new packages had to do with other causes (see
    other changes in the same version of the changelog).

But the reason why all of those were preferred to the "keep packages
    uninstalled" (again, in the default settings with "safety" mode) is because
    this class of solution is ranked in the ::Keep-All-Level, which is higher
    than the others and thus left as the last resort.  It was assumed that "keep
    packages uninstalled" was undesirable because of cancelling all of the
    user's requested actions of packages.

At the same time, the solution where "the package that you requested should
    be removed rather than upgraded, and along this one this dozen too" was at
    ::Remove-Level, in consequence, always offered before ::Keep-All-Level.

It seems natural to have "keeps" being offered at the same "safety" level
    than removal of many packages, and in fact it should be offered before
    removing many packages, including ones that are installed and requested to
    upgrade and trigger the conflict that is being resolved.

This change makes that almost all day-to-day solutions are classified at the
    same level now, excluding exceptional cases like removing essential packages
    or installing non-default versions.  When at the same level, solutions are
    classified by an extra score depending on the actions taken, which is a
    cause of further tweaks in this version, so different solutions at the same
    safety level are not offered randomly in any case.

But perhaps this change doesn't leave the "safety" levels mechanism in a
    very good position, if almost all solutions are always in a single level.
    In any case, I think that it's better to fix the oddity described above
    rather than overhaul a very complex system, and potentially causing many
    more unintended consequences than the one that this change might cause.

* Change how the costs are compared

Costs defer comparisons to "cost implementations" (cost_impl), and these
    were compared based on "structural_level", and when it was equal, on
    "actions".

"actions" is a vector of pairs with "level indices" and "levels".  For
    "levels" only the value is calculated.  But before reaching that point,
    vectors and pairs were compared in a more generic way, so if the vector had
    a smaller number of elements and was equal up to that point, the shorter one
    was chosen as smaller (similar to lexicographical comparisons of strings),
    ignoring the effect of some modifiers in "actions".

This was extremely convoluted to follow and reason about, so a more explicit
    comparison calculation is beneficial.

Additionally, the overall result with the previous comparison is that it
    still produced undesired solutions in many cases, due to the levels of the
    solutions being the same ("safe", "remove", the newly changed "keep-all")
    when the resulting package changes (simple upgrades, removal of packages
    requested to be upgraded, keep current state) are perceived as very
    different in importance / desirability by the users.

The modifiers in the "actions" change the level values a bit, but these were
    not taken into account in many cases in the previous comparison to give
    preference to some solutions over the others.

Maybe these modifiers are not accurate or don't produce good results in all
    cases (they are untested for a number of years due to the behavior of
    comparisons until now, if nothing else), but the new sorting (with the
    combination of the other changes in this release, modifying scores and
    levels) seems to produce much better results overall.

* Apply InstallScore and UpgradeScore also when the packages are not "manual"

For some reason this was only enabled for "manual" packages, even if there
    was nothing in the documentation mentioning this.  This is another step to
    promote Upgrades over other solutions.

- Internal changes:

* configure.ac: Allow to disable check for Boost library headers individually

Note: Should be used only when developing, if at all.

The reason to implement this is that the check is expensive, 1~2 minutes at
    ./configure time (more than 50% of the time that it takes to run the whole
    script); and if it's known that the packages and versions of related Boost
    libraries are there and working then it is unnecessary to check again and
    again.

* Avoid extra code calling apt_load_cache() when already loaded

src/cmdline/cmdline_util.cc
    src/ui_download_manager.cc

The cache just (re)loaded in last steps of download_manager (either
    download_install_manager or download_update_manager).

Loading again is mostly harmless because the function when called detects
    that it has already been loaded and quits, but duplicated code is not good
    in general, and the call was modified several times lately, so it is always
    a maintenance burden (not knowing / noticing that it was actually duplicated
    code, otherwise would have removed it then).

* [cmdline] Rejecting a solution advances to the next one only

Previously it was advancing to the last generated solution, which is
    equivalent at the moment (generates one by one), but not if/when several
    solutions are generated at once (which might happen in future changes).

* [General] Update FSF's postal address everywhere, drop duplicated
    boilerplates.

- Documentation:

* manpage:

* Minor clarification about "install" example (Closes: #268698)

- Translation updates:

* da.po: Danish translation by Morten Bo Johansen (Closes: #817065)

* ja.po: Japanese translation by Takuma Yamada (Closes: #819603)

* Actually enable Dutch (nl) documentation translation by Frans Spiesschaert

[2016-03-05]
Version 0.7.8

- Bug fixes:

* Allow update to happen at the start ("-u") (Closes: #816385)

While trying to make the code to behave the same in download_install_manager
    and download_update_manager, a change was made to make the latter to save
    the "package state" before proceeding.  However, when aptitude is launched
    with "-u", download_update_manager runs before apt_cache_file is loaded for
    the first time, so it's not possible to save the "package state".  So revert
    the behaviour and act as before -- try to save the state, but don't enforce
    it.

* Extra check in update_pkgAcquire_fetch_info() to make sure that pkgRecords /
    apt_packagerecords is available

* Now explains packages being removed when deps are broken (Closes: #342835)

infer_reason() was not checking for this reason for package_auto_removed.

* Avoid crash due to divide by zero in progress counters (Closes: #816431)

* load_tags_from_verfiles(): guard against progress pointer being null

* Use factory from APT to support different progress bars for dpkg actions
    (Closes: #816520)

* Fix problem with recent change that prevented to work with local
    repositories (Closes: #816537)

Even if we would like to not have to get locks and have to call
    fetcher->Run() if no (remote) fetch is needed (see #766122), it is needed
    anyway to work with local repositories (see #816537).

* Fixing crash when invoking curses resolver from command line
    (Closes: #816322)

The solution had already been found to deal with crashing problems involving
    boost::flyweights in the past (copied from "struct close_cache_on_exit" in
    main.cc).  Instead of calling exit() directly, the solution is to invoke a
    sequence of shutting down data structures from apt and aptitude via
    apt_shutdown().

* Fix problem with auto-flag due to persistent Auto-New-Install in pkgstates
    (Closes: #816497)

Auto-New-Install remained in pkgstates after the package was installed.  As
    a consequence, (un)markauto (and maybe some other parts) were not working on
    packages where this had been recorded, because the persistent
    Auto-New-Install was read back upon start and was interfering with the logic
    of the code handling auto-flags.

* Convert std::sprintf to std::snprintf (Closes: #767533)

[2016-03-01]
Version 0.7.7

- New features:

* Only lock package cache dirs and call pkgAcquire->Run() when necessary
    (Closes: #766122)

* [curses] Bindings for reject/approval of solutions in resolver can be
    applied to subtrees (Closes:#475595)

* Several optimizations that improve performance at startup and when
    reading/writing files (Closes: #312920)

See "Internal Changes" for more details.

Basically, when using some basic command that shouldn't perform much
    computation ("aptitude install does-not-exist"), the time was cut down from
    around ~3s to ~1.5s in my system.

The system is a relatively modern computer with SSD disks (but nothing
    bleeding edge), with multi-arch enabled (2 architectures) and close to 90
    thousand binary packages, which is the double of systems without multi-arch
    enabled and affects many operations significantly (like doubling the size of
    the file "pkgstates").

* [curses] Download Size field shows remaining to be fetched (Closes: #446085)

Now it will show "DL: 368 kB/661 kB" instead of "DL Size: 368 kB" when part
    of the files to download are already there, and the field is now aligned to
    the right.  To make room for this in narrow terminals the field "Will use
    43.0 kB of disk space" had been changed first to "Disk usage: +43.0 kB" due
    to other needs, and now to "Disk: +43.0 kB".

The implementation was a bit tricky, though.  The total size of downloads is
    pre-calculated in libapt and readily available; but to check for the actual
    size needed one needs to instantiate and initialize pkgAcquire,
    pkgSourceList and pkgDPkgPM, and then call a method to check for the files
    that are already there on the disk.  The whole operation took only fractions
    of a second (~0.03s in the development system, in the testing conditions),
    but could be worse in other cases or when the disk is slow or busy.

In command-line mode this only happen once, so the overhead is negligible;
    but on interactive systems this is bad because: a) it happens multiple
    times; and b) because interactivity and screen freezes --even if small-- do
    not mix well, and the program seems sluggish.

But specially, due to how aptitude implements redrawing the screen, this was
    done in almost every key stroke, e.g. when moving to the next package/line
    down, so the overhead was very significant.

So a mechanism was implemented (in previous commits) to only retrieve this
    information when the state of any package changes (marked to install, to
    delete, etc.), and to cache the result.  Afterwards, on typical redraws of
    the screen without changes of packages involved (e.g. just scrolling), only
    the cached information is needed, and filling this field takes only 30
    microseconds (in the development system) instead of ~30ms when full check is
    needed.

- Bug fixes:

* [cmdline] Fix crash with "show" and not installed packages (Closes: #815581)

* [curses] Fix for wrong width/properties of some columns in the columnizer,
    incl. "hostname" rendered with 4 characters instead of 8 (Closes: #815554)

Some columns like shortpriority, pin_priority and trust_state should not be
    present in default_widths due to their size being fixed and independent of
    translations.  The mechanism is quite brittle, but maybe it's difficult to
    get something more robust since it involves getting width values that depend
    on width of translated strings.

* [curses] Fix crash when trying to view changelog.  Thanks Wei-Cheng Pan for
    the fix.  (Closes: #815635)

* [cmdline] In "search" and "versions", when width is set explicitly,
    pipes/redirections do not act as --disable-columns (Closes: #815690)

Width can be set through config or command line.  The behaviour to act as
    --disable-columns changed in the last version, 0.7.5; before it was using
    80-width columns by default, or explicitly set width.

* [curses] "%r" (revdepcount) now includes virtual packages (Closes: #320089)

This was caused by the patch to address #270057, PkgIterator::ProvidesList()
    doesn't include virtual packages provided by the visible version (should use
    VerIterator::ProvidesList()).

* [curses] infer_reason() for pkg_unused_removed now has recommends/suggests
    into account in all cases (Closes: #476596)

It was not taking into account several cases when packages were being
    removed (because of being marked as auto-install and not required anymore),
    e.g. when the dependency was downgraded to Suggests, or only showing
    Recommends if config option APT::Install-Recommends was enabled.

Even if APT::Install-Recommends is not enabled, if a package is installed it
    is kept as long as it's recommended (the user has decided to install it,
    despite being only recommended); and similar for Suggests; so the reason for
    removal should include these cases as explanation for being removed at this
    point.

* Fixed case of packages wrongly being marked with auto-flag upon start
    (Closes: #816229)

This was due to variable of extended-state previously_auto_package not being
    cleared when marking the package as manually installed, combined with using
    this variable to decide whether to write "Auto-New-Install: yes" in
    pkgstates in a recent change of 0.7.6, commit 7369d8f9 to address/fix
    #563877, which is another problem caused by the handling of automatic flags.

* Packages to "keep" when applying solutions of the resolver maintain current
    manual/auto (Closes: #815551)

In previous versions, first it was removing the auto flag unconditionally
    (#508428), probably due to APT thinking that it was a decision to keep it
    manually, and aptitude not marking it explicitly as auto.  The fix for
    #508428 in recent versions changed this by setting the flag, but aptitude's
    resolver considers "keep" as a more generic "install_version", with new
    version being the same as current, and the auto-flag being always true in
    those cases.

This is now refined to treat specially the "install" solutions when a
    package is actually to be kept -- first it retrieves the auto-flag of the
    current state of the package, then marks to keep, then sets the auto-flag
    accordingly after asking APT to keep the current version.

- User visible changes:

* [curses] Change "Will use/free %sB of disk space" for "Disk: %sB"

Addresses some concerns of #815554, closed elsewhere.  The new string is
    shorter (helps when terminal width is 80 columnsor so) and should be equally
    clear.

* [curses] In Preview screen, bottom pannel, improve dependency reasons
    explanations for package to be installed (Closes: #814592)

* [curses] Remove option to run "reportbug" on a given package or package
    version (Closes: #463510)

It was mostly an annoyance for the reasons explained in the bug report:
    aptitude often running as root and reportbug complaining, often triggered by
    mistake, and it is not a very useful feature in general.

* [cmdline] Operations like "show", "search", "versions", "why"/"why-not" or
    "changelog" do not need to lock dpkg state directories (Closes: #498061)

Maybe some of the ones which still require it don't need it, but they are
    not used very often and leaving locking enabled is the default, safe option.

- Internal changes:

* Support for most changes in recent versions of apt
    (Closes: #687678, #687686, #687688, #687684)

aptitude had to be adapted already in the last few months for many of the
    changes in recent versions of apt (up to 1.2.*), including some that
    prevented compilation or caused warnings/errors to be emitted when
    downloading changelogs, removed or deprecated API calls, and caused crashes
    in some of the most unfortunate cases.

Keeping the above bugs open, several without any useful information, did not
    help to make the needed changes happen after 3.5 years around; and Wheezy
    and Jessie stable releases went out without these bugs being acted upon.
    Some of the important remaining problems or bugs with actual useful
    information will remain open.  Several, like aptitude not handling config
    options '-o' correctly, are not blocking or related to "catch-up with
    changes in apt" at all, but problems in aptitude in its own right.

In general, changes of apt will keep coming continuously, maybe making some
    of the changes in previous releases irrelevant, so as time goes on these
    older and generic "to-dos" without useful information make less and less
    sense to keep around.

So marking those bugs as closed in this release -- the changes that they
    mention and that are not covered by specific bugs is basically complete, up
    to 1.2.*.

* Move the definition methods of dpkg_selections to the headers (optimization)

These methods are called inside loops many times (based on the number of
    packages, which are many tens of thousands), so it makes a difference in
    common operations which happen very often (e.g. more than 0.1s, when saving
    the file state).

* Lazy initialization of reading "tasks" information (optimization)

This functionality was called upon start from src/generic/apt/apt.cc, and
    taking more than 0.3s (in modern computer with SSD disks), when many times
    in command line mode is not needed.  Now the loading is delayed until it's
    needed (when other related methods are called and expect this information to
    be present).

* Optimizations when reading/writing files

These operations happen typically several times every time that the program
    runs.  The changes save 0.2 to 0.3s (in modern computer with SSD disks),
    with multi-arch enabled (2 architectures) and close to 90 thousand binary
    packages, in a simple test where an inexisting package is requested to
    install in the command line ("aptitude install does-not-exist").

The individual optimizations are:

- Not updating progress for every package when reading/writing files, only
        ~10 times (every 10% increment) instead of ~90 thousand for the test
        scenario above

- Declare some variables, specially strings, out of the loop executing for
        every package -- in that way, initialization and reserving memory is
        saved

- Writing aptitude state file only when complete

* Optimizations when reading debtags

This functionality was called upon start from src/generic/apt/apt.cc.  There
    are two modes, with "debtags" package installed and from "verfiles".

Loading with "debtags" was improved from 0.13s to 0.05s, and "verfiles" from
    0.4s to 0.27s, in modern computer with SSD disks, multi-arch with 2
    architectures enabled.

The improvement consisted in doing some extra calculations to update
    progress only ~10 times (every 10% increment) instead of ~54 thousand
    ("debtags") or ~121 thousand ("verfiles") for the test scenario above.

* Optimizations when building trees for package views

The tests were done in modern computer with SSD disks, multi-arch with 2
    architectures enabled (close to 90 thousand packages to show).

This functionality is used in when building the views in curses mode.
    Creating the tree for the initial default view takes ~0.42s, creating the
    tree for a new default "Package view" ~0.22s, "Debtags browser" ~0.3s,
    "Sources view" ~0.28s, "Flat" ~0.18s, "Package view" with limit "~slibs"
    (section "libs") ~0.09s.

With optimizations enabled, the initial default view takes ~0.34s, creating
    the tree for a new default "Package view" ~0.13s, "Debtags browser" ~0.21s,
    "Sources view" ~0.23s, "Flat" ~0.12s, "Package view" with limit "~slibs"
    (section "libs") ~0.08s.

The improvement consisted in doing some extra calculations to update
    progress ("Building view") only ~10 times (every 10% increment) instead of
    ~90 thousand for the test scenario above (~10 thousand with the limit
    "~slibs").

* src/generic/apt/apt.*: Create get_pkgAcquire_fetch_info() to reuse in the
    future

Update the information when the package installation states change, and
    cache the information, so it can be used for example in the interactive mode
    without the information being retrieved again and again when the screen is
    redrawn (simply moving a line up or down, for example).

* Make Progress parameters to be a pointer in several functions in aptcache.*,
    so it can be passed as null if necessary/desirable

- Translation updates:

* Dutch documentation translation by Frans Spiesschaert (Closes: #815183)

* Dutch translation by Frans Spiesschaert (Closes: #815185)

[2016-02-21]
Version 0.7.6

- New features:

* [cmdline] "show -v" shows all hashes, not only MD5Sum

* Improvements to "why"/"why-not" (Closes: #729349)

It now gives more information about installed versions, manually or
    automatic installations and priority; instead of "Unable to find a reason to
    install/remove" when no dependencies require or conflict with a pacakge.

This enhancement is not only for the command-line commands "why" and
    "why-not" -- it is also for one of the info screens in the bottom half in
    curses/TUI (cycling with 'i'), and typing 'w PKG' in command line prompts
    when requesting confirmation.

* Add support to clean the packages downloaded after successful install or
    similar operations (config option ::Clean-After-Install) (Closes: #110685)

* [curses] "Keep" now works in version nodes (Closes: #585182)

* [curses] "Install" on virtual packages now installs single candidate, or
    emits an error if there are no candidates or more than one (Closes: #174820)

* [curses] Dependency subtrees are now sorted in a pre-determined order
    (Closes: #808882)

* Show Origin URI for packages being untrusted when asking for confirmation
    (Closes: #582064)

It does not explain why they are untrusted (libapt does not seem to provide
    much information) but at least is a better hint than just the package name.

* [curses] In package info screen, "Packages depending on [this]" are further
    split based on the virtual (provided) packages that they depend upon
    (Closes: #159584, #760610)

This helps to avoid the reverse dependencies listed multiple times within
    the same subtree, as it was happening until now; but specially to vastly
    improve the use-case to find out which packages depend not on this package
    directly, but on virtual packages also provided by this package (so perhaps
    an alternative can be installed).

* [cmdline] "search" and "versions" do not truncate columns with
    redirections/pipes (Closes: #445206, #496728)

It will behave as passing "--disable-columns" without column limit (large
    enough number for all practical purposes).

- Bug fixes:

* Properly set a default for $XDG_CACHE_HOME if not set. (Closes: #807545)

* [cmdline] "w" at prompt now actually works (Closes: #555014)

* Refuse to remove aptitude within aptitude (Closes: #319782, #568548)

* [cmdline] Address prompt deficiencies related with translation and input
    methods (Closes: #475802)

* Abort with Failure (rather to continue with the installation) when packages
    fail to be fetched -- except if APT::Get::Fix-Missing is present and set to
    true.  When this happens, the actions in the command line also return with
    non-zero status.  (Closes: #121313, #302784)

* [cmdline] Abort with Failure when actions cannot be taken
    (Closes: #121313, #430392, #445034, #498239, #576212, #639789, #798320)

The Closes of #121313 overlap with other fixes, there are reports of each
    case merged.

* [curses] Adjust widths and "expand"/"shrink"-ability of some fields so
    Broken count and Download size are shown fully even with 80-width terminals
    (Closes: #810221)

* [cmdline] Changelog operations now exit with non-zero on errors
    (Closes: #675833)

* Fix problem showing versioned provides of virtual packages in error message

It was showing candidate version or version of the provider "real" package
    instead of the version of virtual package ("versioned provides" is not a
    very commonly used feature yet, but there were requests to support them
    better).

* Fix problem showing the actual version of the package providing the virtual
    package in error message

It was showing the candidate version of the provider, rather than the
    version actually providing the virtual package -- the candidate version, and
    in general different versions, do not necessarily provide the same virtual
    packages.

* Avoid loss of automatic flags when packages are marked for removal but not
    removed immediately, and the state is saved in between
    (Closes: #686573, #718802, #787663)

Thanks to David Kalnischkies for the investigation and suggestion to fix
    this.

It started to happen in aptitude after 2010 due to a change that happened in
    apt to fix #572364 (a change of a default in a parameter in
    pkgDepCache::writeStateFile() to ignore packages marked as deleted).

* Avoid loss of automatic flags when package actions are scheduled multiple
    times before taking place
    (Closes: #563877)

aptitude has a mechanism to store information about packages-to-be-installed
    that are pulled in automatically, when apt doesn't save that information
    (#435079, commit 1193257d).  When scheduling actions multiple times, it was
    not taking this extra information into account, so the new scheduled actions
    ruined the automatically-installed flag of packages previously scheduled.

* [cmdline] Arguments for "versions" which are not patterns now treated as
    '?exact-name' instead of '?name' (Closes: #691874)

* [curses] "Cancel pending actions" now reloads the cache (roughly equivalent
    to restarting the program), rather than marking all packages as "keep" plus
    ruining all auto-installed flags and holds
    (Closes: #537735, #576319)

* Reinstate auto-installed flag when marking packages to keep in apt cache
    (Closes: #508428)

There were situations like for example in conflicts/solution resolver, that
    after applying the solution "Keep at current version", sometimes packages
    had their auto-installed flag cleared.

* Message explaining unability to fetch changelogs now suggests "update"
    operation (Closes: #456822)

* Do not use ncurses ("visual mode") in dumb terminals (Closes: #317928)

* [cmdline] Do not show "update" progress in dumb terminals (Closes: #757940)

* [cmdline] Catch exceptions when stdin is not available in prompts
    (Closes: #620782)

* Brief explanation when column definitions could not be parsed
    (Closes: #813319)

* Do not download changelogs when they are already being downloaded
    (Closes: #810020)

Until now, pending changelogs kept being queued (e.g. pressing 'C'
    repeatedly in the curses interface spawned many downloads), and in the
    latest versions of apt (>= 1.1) it caused aptitude to crash.  In previous
    versions of aptitude/apt I did not crash, but it caused weird errors
    ("download queue being destroyed").  Maybe internal changes within apt cause
    now crashes when they were errors before (not necessarily apt's fault, maybe
    it's a misuse from aptitude).

The errors already seen in previous versions seem to be caused by aptitude
    code, for example because all downloads with the same URI are deleted from
    some internal structures of aptitude.  With this "fix" at least repeated
    downloads are not repeated (*), which is a nice feature in general, and
    seems to solve this problem.

(*) Still, sometimes the changelog is downloaded and shown twice, maybe
      this is because of sync problems between background threads, or maybe
      because sometimes the download happens so fast that the first is already
      downloaded by the time that the second is queued (this fix only prevents
      to queue when "to-be-started" or "active-downloads", not when it was
      downloaded previously).

More in general, the code related with downloading files/changelogs is
    incredibly complex and entangled, spans many files and dozens of classes
    nested again and using inheritences and overlapping code, and it uses a
    home-grown implementation of threads in cwidget copied or based on POSIX
    threads.  After several multi-hour sessions trying to analyse the point of
    the crash and improve this situation, and failing to wrap my head around it,
    I think that it's probably better to implement a new way to download
    changelogs, which I believe that can be simplified significantly, and
    hopefully in this case other problems will be easier to fix, and we can
    start to use pkgAcqChangelog and avoid the warnings about not being able to
    change the user to "_apt".  But this has to wait for another release.

* Fix so libapt can drop privileges to _apt:nogroup when downloading from the
    network and use pkgAcqChangelog (Closes: #797527, #806595)

When downloading changelogs, aptitude was using temp::dirs which are owned
    by root or the user launching aptitude, and libapt could not drop
    privileges, causing unwanted annoying warnings (#806595).  Since aptitude
    can run as root and normal users, it is also not possible to let libapt
    create files and copy them later: when running as normal users, it is not
    possible to access those files to copy them.  This was changed by letting
    libapt to download to an intermediate place created by aptitude, and copy
    the file afterwards.

Another change is that aptitude uses the specific functionality in libapt
    for changelogs, pkgAcqChangelog, present since apt v1.1.

The whole set of classes dealing with download queues is very complex and
    should probably be rewritten to adapt to real needs and adapt to changes in
    apt over the years.  This is a quick way to fix this annoying item present
    already for months, without ripping apart the whole download subsystem.  See
    also comment of the other entry closing #810020.

* Improve support for trace dumps (Closes: #814408)

Probably due to changes in config variable handling from apt during the
    years, this functionality (related with ::ProblemResolver::Trace-Directory
    and ::ProblemResolver::Trace-File) was copying too many unrelated files,
    including parts of the root fs and causing the temporary directory to
    fill-up.

Improvements included to copy only the needed files, as well as trying to
    safe-guard about similar problems with apt config values in the future.
    Also, removed an extra block of code copying a directory twice by mistake.

- User visible changes:

* [cmdline] Prompt dialog shows lowercase instead of capitalised "yes"/"no"
    (Closes: #607444)

* [cmdline] "search" now exits with non-zero on errors or empty results
    (Closes: #497299)

* Remove the trailing period from some error messages (Closes: #803011)

* [curses] New style for Download Progress in Status bar, with higher contrast
    (Closes: #803980)

* "why" modes, group-by modes and log levels should be provided in English,
    translations not accepted anymore (Closes: #738345)

* [curses] Pressing keybinding "Keep" (":") on package names or versions does
    not remove the auto-installed flag

* [cmdline] Show error message when using --purge (Closes: #434502)

* [cmdline] "show" selects by default the candidate version (as documented in
    man page) and shows extra information when the package is installed but can
    be upgraded, rather than showing "not installed" (Closes: #539978)

* [cmdline] Give more prominence to Version field in "show" command by showing
    it as second

* [cmdline] Improve message about packages similar to mistyped names
    (Closes: #812397)

- Internal changes:

* configure.ac: change order so aptitude CXXFLAGS, CPPFLAGS and LDFLAGS
    override dependencies' (e.g. to set new compiler standards)

* Use pkgDepCache::GetCandidateVersion() instead of GetCandidateVer(),
    deprecated apt API

* Create function to convert from priority to a string and reuse in several
    places

* New apt function: is_auto_installed(PkgIterator)

* Lazy initialisation and better encapsulation of metadata download cache
    (Closes: #807852)

This avoids some problems in builders, like pbuilder (not all env vars are
    cleaned, or for some reason the home of the user invoking aptitude inside
    pbuilder does not exist), and when home or some specific directories are not
    writable for some reason.

This "metadata download cache" is only necessary for screenshots (GTK+,
    possibly Qt?, disabled for a long time and probably removed soon), and to
    store successfully downloaded changelogs after the user explicitly requests
    that operation in command line or TUI/curses mode -- which does not happen
    in every session, and never at all like when autobuilders use aptitude as
    resolver.

* Add common function in apt.{h,cc} to clean cache of downloaded package files

* Convert from some deprecated methods of libapt to supported ones

* Add the common function (class method) add_msg_to_display() in
    download_list.{h,cc} to reuse code in several places

* Move pkg_subtree_with_order to "pkg_subtree.h"

* New util function: is_dumb_terminal()

* New util function: print_ncurses_dumb_terminal()

* New util function: create_temporary_changelog_dir()

This functionality is similar to temp::file and temp::dir (and these were
    used before), but apt v1.1 added a feature by which the process drops
    privileges to _apt:nogroup when downloading files from the network, to not
    have code running as root doing such tasks.

As a consequence, temp::dirs are owned by root and libapt cannot drop
    privileges, causing unwanted annoying warnings (#806595).  Since aptitude
    can run as root and normal users, it is not possible to let libapt create
    files and copy them later: when running as normal users, it is not possible
    to access those files to copy them.

This function supports other code to get around these problems.

- Documentation:

* manpage:

* Explain that "why"/"why-not" need a valid package name (Closes: #535635)

* Improve documentation of "forbid-version" (Closes: #773023)

* Clarify automatic flag treatment with "install" actions (Closes: #469219)

* Fix typo in --autoclean-on-startup (Closes: #812864)

* Guide/User's Manual:

* Make images available in the french translation by copying them from the
      original document (Closes: #414150, #697736)

This is obviously suboptimal because the images are not translated, but
      since 10 of the 11 were missing altogether, this is not making the problem
      worse.  The remaining image of the copied ones was present in the french
      translation, but was missing a key part of the interface described in the
      surrounding text (it was still "wrong", and hopefully the new one is more
      understandable in this context, even if in a different language).

The suboptimal solution is being taken at this point because the bugs have
      been reported almost 9 years ago, and almost 2 years ago I requested help
      from the Debian French l10n team, and there has not been any feedback so
      far.  Perhaps having English images in the French translation (rather than
      missing the images altogether) will spike somebody into action, to send us
      a recent and localised capture to fix the problem properly ;-)

* Add note about ?upgradable (Closes: #498440)

To explain that it just means that there are upgrades available, not
      related at all with "safe-upgrade" or "full-upgrade" operations

[2015-12-08]
Version 0.7.5

- New features:

* [curses] Show Origin and URI in pkg info screen
    (Closes: #294040, #457794, #513622, #611515)

* [cmdline] Print version of provider of virtual package in conflicts/broken
    (Closes: #802943)

* [cmdline] Show packages that will not be upgraded with verbose>0
    (Closes: #553577)

* [cmdline] Notify of 'Download Only' mode before confirmation to continue
    (Closes: #446265, #804287)

* [cmdline] When simulating do not prompt for removal of essential packages
    (Closes: #613049)

* [cmdline] When simulating, add notice before confirmation to continue
    actions (Closes: #173277)

* Use XDG_CACHE_HOME spec instead of ~/.aptitude/cache (Closes: #671780)

* Print useful message when package lists are out of date (Closes: #758764)

* [curses] Allow to hide bottom half in several screens (Closes: #453853)

* [curses] Show hostname on header line (Closes: #398101)

* Log now distinguishes between remove and purge (Closes: #705612)

* [cmdline] Improve error reporting of add/remove-user-tags (Closes: #652421)

* Reuse format string %T also for user-tags (Closes: #498442, #665824)

* Add format strings for Source (%E), Architecture (%e) and Origin (%O)
    (Closes: #248561, #604982, #760608)

* [curses] Provide more info about broken packages in solution screen
    (Closes: #642800)

This screen will now show the extra "(action, version/s involved)":

The following packages depend on cpp-5 and will be broken by its removal:

* cpp (upgraded, 4:5.2.1-6 -> 4:5.2.1-8) depends on cpp-5 (>= 5.2.1-13~)
      * gcc-5 (held/unchanged, 5.2.1-26) depends on cpp-5 (= 5.2.1-26)

* Don't use __DATE__ & __TIME__ when printing version, for reproducible builds

- Bug fixes:

* [cmdline] Fix problems in 'build-depends' causing malfunctions
    (Closes: #802532)

* Fix problem in which alternative dependencies of uninstalled packages were
      not resolved and satisfied properly, causing "Unable to satisfy
      dependencies", when they were actually installable.  Due to a
      mistake/typo, the possible packages were always compared against versions
      of one of the alternatives (the last one), instead of comparing the proper
      package-version of each alternative.

* Messages about build-depends conflicts (unable to satisfy dependencies)
      now show version comparison operators.  There was a mistake in the
      variable to print (dependency type rather than operator).

* [curses] Use default string for Default-Grouping when config is empty
    (Closes: #405970)

* [curses] Improve message when becoming root fails (Closes: #516854)

* [cmdline] For "search", use candidate or, if does not exist, current version
    rather than a random version to show information about the package
    (Closes: #490593)

* Check that the config files are valid, otherwise exit (Closes: #472701)

Upon reading the configuration files it did not check if they were valid,
    and for "~/.aptitude/config" it was writing it back immediately.  The
    writing stopped at the point of the reading failure (instead of just
    skipping the problematic parts), so part of the previous configuration file
    was lost.

It is safer (and not too onerous) to ask the user to fix the configuration
    file before continuing, rather than stomping on valid configuration values.

* Use new config_file.{h,cc} to improve config file management
    (Closes: #504152, #502617, #442937, #407284)

* When becoming root with 'su', pass along "--login" (Closes: #190784)

* Return an error if adding/removing tags without "root" (Closes: #725272)

* Format string '%t' tells about locally installed packages (Closes: #349413)

* Save state before package reconfiguration (to not be lost) (Closes: #474876)

* [curses] Allow to view changelogs of packages in Backports (Closes: #755677)

This was already possible in command line.  Now code was merged in command
    line and curses to work in the same way.

* Get the real pin priority in "versions" and other cases (Closes: #640731)

* Use new user-tags implementation, more secure (Closes: #792601)

* Upgrades can do downgrades when pinned high (>1000, see apt_preferences)
    (Closes: #344700, #348679)

"install" did the correct thing, but the differet upgrade modes
    (command-line and TUI/curses) did not consider to downgrade versions pinned
    higher than 1000, as established in apt_preferences.  apt also behaves in
    this way, so it improves compatibility.

Note that downgrading is highly discouraged in general, though.

- User visible changes:

* [cmdline] Minor improvements to help (Closes: #497136)

* [cmdline] Hide Show-Why reasons when the string is empty (Closes: #576584)

* [cmdline] Slightly improve and reformat --help

* [cmdline] Document add/remove-user-tag in --help

- Internal changes:

* Change APT::Changelogs::Server (src/apt_options.cc) from
    http://packages.debian.org/changelogs to
    http://metadata.ftp-master.debian.org/changelogs -- it is the default for a
    few years already.

* Add function to get the URI of a package version

* Add function to get the Origin of a package version

* Add function to get the candidate version of a package

* Use Boost::Filesystem for some file-related operations

C++ Filesystem TS is derived from it not approved yet, and the support from
    compilers is not great.  When support is good, the switch should be almost
    automatic.

* Add generic/apt/config_file.{h,cc} to help manage config file

* attach/detach_user_tag() now return results of the operation

* Create function get_user_tags() for compartimentalisation and reuse

* Changes to support apt-1.1/libapt-pkg5.0

* Improve user-tags implementation and move to own file, away from aptcache

- Documentation:

* manpage:

* Separate two elements in --add-user-tag-to description with comma, they
      were displayed together

* Guide/User's Manual:

* Add keybindings for menu bar (Closes: #365298)

Add an indication in the document that "Control+[space]" and "F10" are
      also valid.

[2015-10-16]
Version 0.7.4

- New features:

* [curses] Show providers of virtual packages in "description" area
    (Closes: #103964)

The description area (bottom half of the screen in the default view) was
    completely empty for virtual packages.  Now it shows the list of "real"
    packages providing the virtual package, in a nicely formatted list.

- Bug fixes:

* Retrieve again long descriptions (Closes: #801460)

When disabling the #ifdef of HAVE_DDTP, it was done the wrong way around and
    the old code (untested for many years) compiled fine and didn't cause
    errors, but didn't retrieve long descriptions anymore (it did for short
    ones).

* Fix for circular dependencies in internal_mark_delete() (Closes: #801430)

Under some circumstances, when following reverse dependencies of packages to
    be deleted to see if they are automatically installed and unused (so they
    can be pro-actively marked for deletion as well), the function calls itself
    recursively.  In this case, it uses this version with an extra parameter to
    detect when packages were already visited, to avoid infinite loops in the
    case of circular dependencies (bug #801430).

* Fix race condition replacing ~/.aptitude/config (Closes: #764046)

- User visible changes:

* [cmdline] In versioned provides, include '=' symbol (Closes: #767393)

At the moment, there is only one symbol ('='), and it is hardcoded in dpkg
    and apt, so doing the same to avoid possible confusion among users, as
    suggested by David Kalnischkies from APT Team.

* [cmdline] "show" now shows arch of packages in multi-arch systems

Until now, it was not appending the arch in Depends and other places, so
    there was output like:

Package: dput-ng

* [curses] Use 'w' in action column for package downgrades (Closes: #801310)

In the column that shows the action selected for the packages (between
    current installation state and automatically installed), e.g. in the main
    package view and the preview screen before installing of the curses
    interface, there was no character for downgrades.  There was 'u' for
    upgrades, 'd' for removals, 'p' for purges, 'h' for holds, etc., but the
    action character for downgrades was missing, so the column was left empty --
    as it was an specific background colour until recently.

* [cmdline] Show feedback of some commands (hold, forbid-version, ...) with
    verbose>0 (Closes: #270033, #638841)

* [cmdline] Require args for some commands: hold, keep... (Closes: #759520)

- Internal changes:

* In internal_mark_delete(), also check for auto-installability property of
    real packages providing virtual packages to stop them being marked for
    deletion.  can_remove_autoinstalled() checks for this anyway, but the
    implementation could change in the future, and it shouldn't hurt to double
    check.

* Convert some instances of boost::unordered_{set,map,multimap} to std::

* Convert some instances of boost::hash to std::

* Remove two uses of boost::lexical_cast, use std::to_string() instead

* Create utility function remove_non_recursive()

- Documentation:

* manpage:

* Remove wrong assertion that safe-upgrade does not accept --full-resolver
      (Closes: #560991)

* Document missing &BD specifier when installing packages (Closes: #696568)

* Guide/User's Manual:

* Update renamed config option ::CmdLine::Show-Summary (Closes: #776789)

The config option used in the code is ::CmdLine::Show-Summary, but in one
      place in the documentation it was named ::CmdLine::Why-Display-Mode
      (probably from an incomplete rename).

* Correct some wrong examples of search patterns (Closes: #519456)

[2015-10-07]
Version 0.7.3

- Bug fixes:

* [cmdline] Correctly calculate the indentation for multi-byte encoded strings
    in command line "show" (Closes: #360202)

* [curses] Show intended action when downgrading (Closes: #516517)

In package view/info screen, it was not handling this action and not showing
    anything in this case.

* Update internal state for upgrades/downgrades with target version after the
    action is performed (Closes: #787658, #714429)

Thanks to David Kalnischkies and Julian Andres Klode from APT team for their
    help, clues and patience.  It took some serious effort to get to this fix,
    which in the end is quite modest in terms of code changes.

Internal state was neither reset nor written to disk until other packages'
    states changed, so aptitude marked the same action on the packages as
    pending to be performed again and again (but the action had already been
    taken, so there was no observable effect in terms of installations).

However, this meant that the packages that were downgraded to older versions
    when newer were still available (e.g., mixing stable and unstable), was not
    shown as "Upgradable" neither in the current sessions nor in subsequent
    sessions (under Upgradable subtree in interactive mode; or command line like
    "aptitude search ~U"), until the file pkgstates was written to disk because
    of changes in other packages.

* [curses] Don't precede Tags field by newline in package info screen
    (Closes: #799933)

* Correctly detect state of vers/pkg when is ConfigFiles (Closes: #698768)

* [cmdline] Show "RECOMMENDED but will not be installed" on pipes and redirs
    (Closes: #647474)

The change was requested in #452202 in 2007 to not show this message and was
    applied, but after that there are at least 3 separate requests (#647474,
    #587676 and #720074) asking to show the same messages independently if the
    output is an interactive terminal, a pipe or a redirection to a file, all
    citing the lack of this message.  (Makes sense, because it is one of the
    most prominent messages that users see, and also because this way of hiding
    messages is almost never used elsewhere in the code).

In principle, "quiet" shouldn't make a difference when using ttys or
    pipes/files, but it does because it's primarily tied to the "progress"
    messages appearing all around the command line code; so in main.cc quiet is
    set to "1" when the output is not a tty.

I think that the best solution by now is to revert the behaviour and simply
    show the message whenever there are packages to show.  The only harm is if
    people complain again that it's too verbose, but probably nobody is using
    "-q" in practice to avoid having this message printed.

A proper implementation would involve to clean-up the mess of quiet/verbose
    and convert it to only one single variable, and act verbosely accordinly,
    and perhaps tie the condition of showing progress of operations on another
    variable/mechanism.

* [curses] Improve the integration of Forbid upgrades (Closes: #439258)

Now it will advance the selection to the next line after marking a package
    with 'F', if that option is enabled.

* Remove unneeded automatically installed packages in the same action
    (Closes: #478116, #564545, #637257, #368037, #486454, #738517, #789803,
    #779999, #756507, #759764, #766702, #655483, #740009)

There were some cases where manually installed packages were removed/purged,
    but dependencies that were needed only by these packages (marked as
    automatically installed, and unused after the removal of the main package)
    were not removed as part of the the same "action", due to interactions
    between aptitude (in find_not_orphaned()) and libapt.

The packages were detected as "garbage" in subsequent runs of apt (offering
    to "autoremove" them), aptitude in the command line, or further actions
    within the interactive session of aptitude; but nevertheless this caused
    numerous complaints about aptitude not removing the "cruft" (sometimes
    assuming that because it was not removed immediately, it will not be removed
    later either).

Now, as part of the removal of a package and unless the option
    "::Delete-Unused" is set to true (defaults to false); aptitude pro-actively
    marks for removal the dependencies of the package marked as automatic and
    not used by other packages; and find_not_orphaned() was modified to only
    have into account installed packages or to-be-installed packages to prevent
    removals.

* Honour ::Purge-Unused when removing packages (Closes: #724034)

* Be more informative when virtual packages are involved in broken deps
    (Closes: #316633, #798898, #799918)

* Fix description of config option ::AutoClean-After-Update (Closes: #756937)

- User visible changes:

* Make boundaries of sessions in the log file more clear (Closes: #269275)

* [curses] Avoid marking as auto/non-auto if already set (Closes: #265013)

* [curses] Print message when starting to perform actions (Closes: #323371)

* Use uppercase APT:: for apt config vars, for consistency (Closes: #519425)

Both APT:: and Apt:: (the other common form that we were using) are valid,
    in fact they are case-agnostic.  But for internal consistency and specially
    for consistency with APT documentation (apt.conf), use the uppercase form.
    
    This mostly affects documentation, but also some code and translations.  It
    was substituted automatically in all translations.

* [cmdline] Print versions of Provides, if they exist (Closes: #767393)

Some aspects of the bug report refer to the curses TUI and it is still
    unclear how to deal with them, so it was cloned to another report; but the
    change implemented for this part could be useful, it is harmless, and it
    simplifies code (two branches differentiating for this reason now merge).

- Internal changes:

* temp.cc: simplify code and messages and reduce the use of boost libs

* configure.ac: Remove checks for boost/scoped_array.hpp and boost/random.hpp,
    not used anymore -- a few seconds less per compilation

* In file pkg_ver_item.cc, function pkg_ver_columnizer::setup_column(), the
    switch/case handling for longstate was missing the options added in 2007 for
    APT_HAS_TRIGGERS, present for stageflag case and both cases in
    pkg_columnizer::setup_column() of pkg_columnizer.cc.

(In other words, it was missing in 1 of these 4 places where it is
    necessary).

* Disable obsolete checks in configure.ac and preprocessor checks in code for
    APT_HAS_TRIGGERS, APT_HAS_HOMEPAGE and HAVE_DDTP.

The support for these functionalities has been present in all involved tools
    since 2007-2008 or earlier, so it is safe to disable the checks and the
    dead code.

* Add functions to check if packages are installed, automatically installed,
    if they are virtual, and others.  They can be used later to make other code
    more consistent, clear and clean.

* Remove sigc++ include from apt_config_widgets.h (fails to build with newer
    versions)

- Documentation:

* Guide/User's Manual:

* Document Brown colour for downgraded packages in UI (feature implemented
      in the last version)

* Dutch by Frans Spiesschaert (Closes: #800516)

[2015-09-17]
Version 0.7.2

- New features:

* 'Escape' key cancels input dialogs (search, limit, etc.) (Closes: #493322)

* Extend "firstchar" grouping policy to optionally use source package names.

With "firstchar(binary)" or the default "firstchar" it will use binary
    package names (same behaviour as before); while with "firstchar(source)" it
    will use source package names.

This is useful for example when browsing packages coming from the same
    source package ("source" grouping policy) within large collections
    (examples: all installed packages, all upgradable packages, all packages
    from "main" section), to add an intermediate grouping step.  In this way,
    one can for example emulate the hierarchy of FTPs (try grouping:
    "section(topdir),firstchar(source),source").

* [curses] Add 'New Source Package View' to Views menu (thanks Thadeu Lima de
    Souza Cascardo, see #497206), with some updates and minor modifications,
    like more complex grouping.

The menu entry was removed before applying the patch attached to that bug
    report, see comment to the commit: 66adb6c872f7b49279da43601e7d3ff199996c1a

* [curses] Use Yellow/Brown colour to highlight downgrades (Closes: #584510)

Previously downgrades were not highlighted, so it was bit confusing/odd and
    it looked as if nothing would be done with the package.

There are not many colours "left" in the limited choice, only Yellow/Brown
    (same as downloads) and Blue.  Since Blue is used in the menus, Yellow/Brown
    is probably better; Downgrades and Downloads are never on the same screen.

* Log file now contains version information for most actions (Closes: #222585)

Previously it only contained version information for upgrades and
    downgrades, both current (old) and candidate (new) versions.  Now most
    actions show version information, either the candidate version
    (e.g. install, auto install) or current version (remove, hold, ...).

* Save selection state of packages to dpkg database (Closes: #137771)

Aptitude maintains a separate database (in "pkgstates" file), with a field
    Dselect-State to keep track of its selected state in dpkg ("status" file).
    This is updated upon start of aptitude or some operations, so aptitude is
    aware of changes of this selected state made by other tools; but it was
    never updated back to dpkg after the selection state changed in aptitude.
    As a result, for example packages set "hold" in aptitude were then not
    respected by other tools which do use dpkg selected states.

* Consider packages "unknown" to dpkg as not to install (Closes: #328616)

While aptitude tried to take into account the selected state of packages in
    dpkg, the ones not present (with state "unknown", meaning never installed,
    or purged) were ignored in aptitude, and the internal selected state was
    used.  This was causing problems like not respecting actions taken with
    other tools (see #328616 and duplicates) -- installing with aptitude and
    then purging with either dpkg or apt (or higher level applications, like
    puppet), meant that in the next run of aptitude it would try to install the
    package again.

We now save the selected states of packages from aptitude to dpkg (another
    feature added in this release), so the selected states are synchronised.  If
    it's "unknown" to dpkg, we will assume that other tools uninstalled it in
    between aptitude runs, and we will keep it uninstalled.

The behaviour of scheduled aptitude actions will be preserved: if a package
    is selected to install but is not actually installed in the session,
    aptitude saves the selection in dpkg as "install", so it will be attemped to
    install in the next aptitude runs (or other tools honouring the selected
    state in dpkg).  Or if a installed package is marked to purge with "aptitude
    --schedule-only purge PKG", "dpkg --purge --pending" does honour the
    request.

- Bug fixes:

* Disable strings gathered for translation (Closes: #790568)

* Change to try to make updated status stats more clear (Closes: #458351)

* [cmdline] Correctly print when a package should be purged (Closes: #798286)

* [curses] With the option of mini-buffer prompts enabled, cancellation of the
    "Quit confirmation" with 'Escape' or 'Ctrl-g' does not cause the
    dialog/prompt to stop working (Closes: #607118)

* [cmdline] Warn when package cannot be marked/unmarked auto (Closes: #498240)

* Install signal handlers and do clean-up when terminating abruptly
    (Closes: #558352)

* [curses] Set better ordering for groups of Preview Actions (Closes: #434352)

- User visible changes:

* Change error string of source_policy_parser to be the same as the rest

* [curses] Improve titles and descriptions of views

- Internal changes:

* Improve retrieval of source package information with (upcoming) APT 1.1.

Thanks to David Kalnischkies for the suggestion and implementation advice.

Information about source package and version will be in the binary cache,
    and available via the VerIterator (ver.SourcePkgName() and
    ver.SourceVerStr()); and it is much faster than parsing the package record.

Additionally, retrieving the source package name in that way defaults to the
    binary package name if no Source record is explicit, so there is no need to
    check if it's empty.

It is not used in many places in the aptitude code (about 6 files and 10
    different functions/places), but this speeds-up and simplifies the code
    considerably where it was used.

* New helper dpkg_selections.{h,cc}, to help to manage saving selections to
    the dpkg database (--set-selections)

- Documentation:

* Guide/User's Manual:

* Remove grouping policy "hier" from doc/??/aptitude.xml (the
      categorial/hierarchical browser features were removed in version 0.7)

- Translation updates:

* Russian by Lev Lamberov (Closes: #798485, #769428)

[2015-09-06]
Version 0.7.1

- Bug fixes:

* Fix for wrong reported size of deleted files with 'autoclean' on 32-bit
    arches (Closes: #499872)

* Be explicit when packages are already installed, cannot be removed/purged
    because they are not installed, and similar (Closes: #421469).

It was changed to work in this way a few years ago in #258913 due to the
    installer, and required to pass verbose flag to print these messages, but
    this was caused at least 3 bug reports (merged) to be explicit, and aptitude
    prints many other messages even ignoring these lines.  It can be made to be
    quiet with another flag, if needed.

* Check string formats for columns in both curses and command line interface,
    and forbid characters which can lead to cwidget assertions and program
    crashes.  These strings can be specified in the the command line for
    "search" or "versions" with -F or configuration options (and they can be
    made permanent by mistake, causing crashes upon start, as the bug reports
    prove). (Closes: #497129, #532662).

- Documentation:

* Quick help (help.txt):

* Document 'l' (Limit Display) in quick help (Closes: #514541)

* Improve description of '_' (Purge) (Closes: #495326)

* Improve the description of the search shortcut, and point more clearly to
      search patterns in the full documentation

* man page:

* Fix example of '-F' with current and candidate versions (Closes: #752517)

* Guide/User's Manual:

* Upgrade doc/??/aptitude.xml documents from DocBook XML 4.2 to 4.5

* Use XHTML 1.0 rather than HTML 4.01, at least to have something from this
      decade/century.  The resulting documentation still does not fully validate
      (see #496724), I think that due to bugs/problems of docbook-xsl
      conversions using invalid elements in the different standards (tried HTML
      4.0, 4.01, XHTML 1.0 and 1.1).

* Generate 'alt' tag for images in HTML documentation (see #496724)

* In "Customizing the package list", fix order of variables
      ::UI::Package-Status-Format and ::UI::Package-Header-Format and their
      explanations

- User visible changes:

* Slightly change description of shortcut 'g' in title bar (Closes: #247487)

- Internal changes:

* search_graph.h, fix problem with code which was working for many years (with
    boost 1.55 and many versions before), but now the straightforward option to
    convert boost::optional to bool does not work with gcc-5.2 and boost-1.58,
    so use .is_initialized() instead.

* solution_item.cc, copy string of package name coming from libapt because it
    does not guarantee that the string is valid for all of the time span that we
    need it, to not show garbage that it happens sometimes
    (Closes: #795150, #795028)

* match.cc, pkg_info_screen.cc, reason_fragment.cc: remove and modify code
    relying on pkg.Section() (from apt PkgIterator), it is deprecated code and
    it will get removed soon according to the apt team (Versions have Sections,
    Package in abstract doesn't have unique Sections)

* aptitude_resolver.cc: use std::unique_ptr instead of deprecated SPtrArray

* Add compatibility for APT 1.1:

* Create DepIterator values from Dependency pointers on-the-fly, where required

* Adjust AcqQueuedFile() for changed signatures of overriden methods

* Improving C++11 compatibilty mode:

* Convert std::auto_ptr (deprecated in C++11) to unique_ptr

* Convert boost::scoped_ptr (deprecated in C++11) to std::unique_ptr

* Convert instances of boost::shared_ptr, make_shared, and weak_ptr to be
      explicitly prefixed by boost::, otherwise they clash or have problems
      compiling with the new C++11 std::shared_ptr and analogues (many were not
      converted in the previous version).

* Remove unused function serialize_pattern_list()

* Remove unused function wcsempty()

* Improvements of the autoconf/automake infrastructure.

* No more generate a dummy ChangeLog file just to please automake.

* Clean up some more leftover files in "make maintainer-clean"

* Use 'cp -u' when copying gtest and gmock, so they don't need to be
      recompiled every time

[2015-07-25]
Version 0.7

- Changes in the versioning scheme and changelog:

* From now on Aptitude's version numbers follow loosely the Semantic
    Version specification (http://semver.org/), with a few exceptions:

* The leading zero is kept for now. The first digit after "0." is
      currently considered being the major version.

* Trailing zeros may be omitted, i.e. 0.7 is the same as 0.7.0.0
      with 7 being the major version.

* Dates in the NEWS file are now consistently written in an
    unambiguous and more international way.

- Feature removals:

* The content-wise outdated and not-multiarch-compatible categorical
    browser has been removed. The Debtags browser has replaced most of
    its functionality already. Local package groups are no more
    available, though.  (Closes: #686124 and its duplicates as well as
    #686142 and #686646 as well as LP: #1082198)

The removal discussion has taken place in #686646.

- Bug fixes:

* Fix reported installed size change when installing/deinstalling packages
    which are bigger than 2 GiB (int type size 32 bits).  Thanks Benny Baumann
    and Jason Rhinelander for the report and info, and Sven Joachim for the
    patch.  (Closes: #759769)

- Internal changes:

* Use automake option subdir-objects to be able to use current
    automake versions.

* Copy in configure.ac from /usr/src/gtest/src/gtest-all.cc and
      /usr/src/gmock/src/gmock-all.cc to subdir tests/ -- otherwise, automake
      (with subdir-objects option recently added) tried to build in
      /usr/src/gtest/ and ../gmock/, and then failed to link

* Remove forward declaration of STL templated classes and containers
    (basic_string, pair, vector...), use regular includes instead.  Due to
    internal changes of GCC-5 or libsdtc++ related with C++11 compatibility
    (std::string and std::list had to change), the code failed to compile, and
    there is not enough justification to "forward-include" in this case (it has
    to be done copying declarations by hand, it's prone to errors when things
    are updated in the backstage and not very elegant).

* Changes to allow to compile with C++11 compatibilty mode (prompted by
    changes in the toolchain in Debian):

* Convert all instances of boost::make_shared and boost::shared_ptr to be
      explicitly prefixed by boost::, otherwise they clash with the new C++11
      std::shared_ptr.

* Convert some instances of boost::shared_ptr and boost::make_shared to the
      corresponding versions now in the standard library.  The reason for this
      is that it failed to compile straight away with the version in unstable
      (boost-1.55) in some sections of the code (e.g. problemresolver, sqlite,
      file_cache), and because since it is now part of the standard, there is
      little reason to use Boost for that.  The rest of cases not covered in
      this version shall be converted later on.

* Several other minor changes to allow to compile with C++11.

* Remove duplicated method in sqlite.* files (below).  There is another method
    with the same signature but with "const std::string&", and "const char*"
    implicitly converts to use that one if there is not one available of the
    same type.

std::shared_ptr<statement> statement::prepare(db &parent, const char *sql)

* Add top-level update-po target for not needing to remember in
    which directories the update-po target needs to be called.

Version 0.6.10

Note that 0.6.9 was an experimental release.  Most of the changes it
contained are temporarily reverted, but they will return.

- New features:

* New sort policy 'installsizechange', for sorting by change in installed size
    of each package when the desired actions are applied (Closes: #676075)

- Bug fixes:

* Fix segfault and show the correct changelog when executing "aptitude
    changelog <source-package-name>", and no binary packages in that source
    package match the source package name (Closes: #723821)

* Use new URL to grab changelogs, redirections were set up so it is not
    currently a problem, but the new location seems to be the canonical place
    for metadata (Closes: #708345)

* Fix incorrect results with some sorting policies (Closes: #720750)

- Internal changes:

* Change INCLUDES to AM_CPPFLAGS in automake files to avoid warning:
    "'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')"

- Documentation:

* Update manual to refer to canonical git repository.

- Translation updates:

* Improve and explain some translation messages, thanks helix84@centrum.sk

- New features:

* Get changelogs also when package origin is from "Debian Backports" and not
    only "Debian", thanks Gerfried Fuchs (Closes: #714619)
  * New sort policy 'debsize' for sorting by package size, thanks Marcel Partap
  * Add "Reinstall (shortcut L)" to the package menu (Closes: #633788)
  * Add descriptions for sections introduced in 2011 (education, introspection,
    metapackages) (Closes: #674681)

- Bug fixes:

* Do not group packages as tasks based on their name, rather, use their

[2012-09-07]
Version 0.6.8.2                             "Say 'what' again"

- New features:

* [all]: Support for matching architectures using specification
           strings and wildcards (for example, "linux-any").  See
           Debian Policy section 11.1 "Architecture specification
           strings" for more details.

- Minor bugs:

* [cmdline]: Fix typo which prevented installing tasks using the
               apt-get compatible syntax ("aptitude install
               gnome-desktop^").

* [cmdline]: Do not assume that APT::Default-Release always provides
               the candidate version of a package, instead use the
               policy defined by apt_preferences(5).
               (Closes: #587775, #631464, #686316)

* [all]: Download changelogs from APT::Changelogs::Server instead
           of a fixed location, and replace very ancient and disused
           option for Aptitude::Changelog-URL-Template.
           (Closes: #687239)

- Documentation:

* Update for default value of APT::AutoRemove::SuggestsImportant
    which is "true" since apt 0.8.15.3. (Closes: #685310)

* Correctly reference APT::AutoRemove::RecommendsImportant and
    SuggestsImportant which do not contain any hyphens.
    (Closes: #579071)

- Translation updates:

* Czech (Closes: #681693)
  * French (Closes: #680040, #685084)
  * Polish (Closes: #678153)
  * Russian (Closes: #686016)
  * Spanish (Closes: #686752)

[2012-08-25]
Version 0.6.8.1                             "Don hat"

- Crashes and serious errors:

* Multi-arch update for the problem resolver:
    - handle conflicts without removing all foreign-arch
      packages (Closes: #672340) (LP: #831768)
    - correctly recognise dependencies solved by Multi-Arch:
      foreign packages (LP: #968412)

- Minor bugs:

* [curses]: Use dpkg package names when calling dpkg
              (Closes: #680333)

- Internal changes:

* Add (temporary) helpers for interacting with dpkg.

[2012-05-11]
Version 0.6.8                               "Never need a reason,
                                             never need a rhyme"

This version of aptitude requires apt 0.9 and will not build against
earlier releases.

- Crashes and serious errors:

* [all]: Fix build with g++ 4.7
           Thanks Adrian Lang for the patch (Closes: #672335)

- New features:

* [all]: Support really big files in the download system

This follows recent changes in apt which added support for
           files greater than several gigabytes in size -- using the
           'unsigned long long' type to store the file size.

* [all]: Update to tasks support: task packages, multi-arch, syntax

Task packages (introduced with tasksel 3.0) are
           meta-packages which define the dependencies of tasks.  The
           packages themselves have always worked but the 'tasks'
           grouping policy and '?task' search term did not support
           them.  This update corrects for this.

As a result of this change to tasksel all Debian tasks now
           function exactly like meta-packages. (Closes: #382631)

The syntax for installing tasks from the command line has
           been updated.  It now supports specifying an arch and
           requires the same syntax as apt-utils ('^' must be the last
           part of the name).  Examples:

# aptitude install gnome-desktop^
             # aptitude install ssh-server^:armel

This avoids ambiguity that may arise when a task and
           package have the same name.

- Minor bugs:

* [all]: Changelog downloading is restored
           (Closes: #669569, LP: #824708)

* [cmdline]: Exit with non-zero status when a package run is
               aborted. (Closes: #293008)

* Restore candidate version on undo, keep

Previously, undo incorrectly restored the candidate
    to be currently installed version.  Keep did not
    restore it at all. (Closes: #529403)

- Cosmetic and UI bugs:

* [curses]: Adjust default widths of localized columns:
              broken_count, downloadsize (Closes: #674045)

* [all]: Fold some near-duplicate strings

* [curses]: Update package views after 'Cancel pending actions'
              (Closes: #595753)

- Build system changes:

* Remove redundancy in doc build system

Lots of code was duplicated between makefiles for the
    various translations.  Much of this is now in common
    rules files making it easier to add new translations.

- Documentation:

* [doc]: Add doctype headers to html docs.
  * Italian translation (Closes: #674664)
  * Fix minor errors in documentation. Thanks to Beatrice Torracca
    (Closes: #674675)
  * Fix groff warning in manpage (Closes: #675085)
  * Fix encoding problems with README files
  * Install some localized README files which were previously
    left out.

- Translation updates:

* French (Closes: #673827, LP: #642840)
  * German (Closes: #672467, #668875)
  * Simplified Chinese

[2012-05-02]
Version 0.6.7                               "I said 'Step pause turn
                                             pause pivot step step'"

- Crashes and serious errors:

* [cmdline]: Avoid dpkg and infinite loop in download-only mode
               (Closes: #629266) (LP: #975793)

* [cmdline]: Check for apt_init errors in cmdline_download.cc
               (Closes: #670379)

- Minor bugs:

* [all]: Fix various locking issues:

- 'install' actions lock /var/cache/apt/archives

Other tasks which access that directory (such as 'apt-get
             clean') will now fail if aptitude is downloading or
             installing packages. (Closes: #370381)

* [all]: Actually use aptitude::Logging::Levels (Closes: #654344)

- Internal changes:

* [all]: No longer use ListUpdate (from libapt-pkg) to update package
           lists.  Instead, restore the previous code and update it to
           include the semantics from ListUpdate which were missing.

ListUpdate was too coarse to suit download_update_manager
           properly even though it more-or-less worked.

* [all]: Do not call debtags on list update.  This was a rather
           unsightly kludge is better suited as a script for
           APT::Update::Post-Invoke.

* [all]: Destroy download_threads when done with them.  The objects
           were previously left undestroyed, consuming resources and
           keeping, e.g., locks open longer than needed.

- Cosmetic and UI bugs:

* [curses]: Apply patch from Ubuntu: don't mention 'su' in 'Become
              root'.

* [cmdline]: Use arch-qualified names in 'Provided by' for virtual
               packages (LP: #972847)

* [curses]: Preview screen ignores Pkg-Display-Limit

Previously it would apply that limit if
              UI::Preview-Limit was not set.  This was causing
              confusion and it is more useful to have these as two
              clearly distinct settings. (LP: #381507)

- Build system changes:

* [all]: Include build of gtest when building gmock. (Closes: #670403)

* [all]: Fix check_boost.sh for out-of-tree builds

- Documentation:

* [doc]: Apply patch from Ubuntu: update Finnish manpage to point to
           doc package.

- New translations:

* Croatian (Closes: #667934)

[2012-03-17]
Version 0.6.6                               "There is not one you,
                                             there are many."

This version of aptitude brings in basic multi-arch support.  Similar
to APT, foreign-arch packages are displayed using their full name,
including architecture, for example: 'libc6:armel'.

This is intended to provide some support for users of multi-arch
systems without causing huge breakage.  For users of single-arch
systems the changes are limited to displaying the full names of all
packages in log files and internal messages.

CAUTION: The problem resolver is not yet updated to handle multi-arch
properly.  Do not rely on it to make intelligent suggestions at this
stage, instead, use the architecture information to manually check and
resolve any problems.

- Removed features:

* [gtk]: Remove menu entry for minesweeper.  This was causing
           security concerns by potentially invoking an external
           program with root privledges. (Closes: #552522)

- Security fixes:

- Crashes and serious errors:

* [cmdline]: List update errors are reported. (Closes: #451137)

* [all]: Fix '?action(upgrade)' and others (were finding kept
           packages instead).  Thanks to Rogier <rogier777@gmail.com>
           for the patch (Closes: #603862)

* [curses]: Hack to prevent debug messages dumping to the screen
              (Closes: #651748)

- New features:

* [all]: Basic multi-arch support as discussed above.

- Use arch-qualified names (full names) in most places.
      - Sorting by name considers full names (i.e. architecture).
      - Show architecture and multi-arch fields in package info.
      - Store package states uniquely by name *and* architecture.
      - Add related search terms:

* ?architecture(architecture), ~rarchitecture
          Select packages for the given architecture (such as
          "amd64", or "all").  Special values: "native" and
          "foreign".

* ?multiarch(multiarch)

Select packages with a multi-arch capability of multiarch
          (that is, either "foreign", "same", "allowed", or "none").

- Default search (with no explicit term) now accepts "name:arch"
        patterns which match "?exact-name(name)?architecture(arch)".
      - Add architecture grouping policy.

(Closes: #659079, #661744)
      (LP: #454941, #845136, #884945, #904486)

* [curses]: Use libraries ("liba", "libb", etc.) with 'firstchar'
              grouping policy.  Removes crowding of the "l" group.

- Minor bugs:

* [all]: List update now runs APT::Update hooks. (Closes: #476399)

* [cmdline]: Actually silence progress messages with '-q2'.
               (Closes: #141719)

* [all]: Fix various locking issues:

- '[auto]clean' locks /var/cache/apt/archives;
           - 'update' locks /var/lib/apt/lists; (Closes: #653479)

* [all]: Fix 'priority' cost level in resolver.  The values should
           have been negated but were not.  Thanks to Modestas Vainius
           for this one. (Closes: #608786)

* [all]: Make ~VCURRENT etc. behave like ?version(CURRENT).  A
           latent bug was preventing the special values from being
           handled by the short form.

- Internal changes:

* [all]: Update package lists using ListUpdate (from libapt-pkg).
           Now the process is identical to apt-get and other tools,
           reporting errors more correctly and running the APT::Update
           hooks.

* [all]: Refactor various APT-related comparison functors which
           were spread all over the place.  There is now a single
           implementation of each which resides sanely in apt.h.

* [curses]: Refactor duplicated make_{info,dep,ver}_screen + insert
              code.  Three new functions replace all standard uses of
              the previous code: show_info_screen, etc.

- Cosmetic and UI bugs:

* [cmdline]: Fix some help and prompt strings which wrongly included
               localized names for commands such as 'why'.
               (Closes: #486615)

* [curses]: Change ordering of top-level sections to match the order
              in aptitude::Sections::Top-Sections.  The default order
              is now: main, contrib, non-free.  (Closes: #181997)

* [curses]: Improve error messages when parsing grouping policies to
              use the user-visible names, rather than the internal
              names.  (Closes: #231595)

* [all]: Change default width of %D, %I, %o, and %Z.  Thanks to
           Michał Kułach for this one. (Closes: #599209)
           (LP: #741417)

* [all]: Change default width of %V, %v to 14.  This greatly increases
           the number of versions which will display completely.
           (Closes: #624542)

* [cmdline]: Use nice formatting for both parts of the download
               progress display.  Previously the 'downloaded' size was
               being reported in bytes; now it uses larger units as
               appropriate to be more readable.

* [cmdline]: 'versions' now groups it's results by 'package:arch'
               instead of 'package'.

* [all]: Cleared up grouping, sorting policy error messages.
           (Closes: #231595)

- Build system changes:

* [all]: Add configure option '--disable-tests'.

* [all]: Don't check for libvte if GTK+ is disabled.

* [all]: Apply patch from Ubuntu to fix build -D_FORTIFY_SOURCE=2
           errors.  Thanks to Colin Watson and Michael Vogt
           (Closes: #497539)

* [all]: Avoid most library and header checks if --disable-aptitude.

* [all]: GTK+ frontend is disabled by default.

* [all]: Enabling GTK+ or Qt is an error if libraries are missing.

- Documentation:

* [doc]: Minor correction to the user's manual. (Closes: #365485)

* [doc]: Clean recent changes to man page description of
           'forbid-version'.

[2012-02-06]
Version 0.6.5                               "Splat!"

- Removed features:

* [cmdline]: Remove broken safe-upgrade-only options.

Specifically, Safe-Upgrade::No-New-Installs and
               Safe-Upgrade::Show-Resolver-Actions.

These options were documented but have never worked.  A
               quick skim didn't turn up any bugs filed about them, so
               I guess no-one ever tried them.  Removed them.

- Minor bugs:

* [all]: Do not translate program options in Catalan translation.
           (Closes: #462558)

* [all]: Do not translate program options in Simplified Chinese
           translation. (Closes: #563132)

[2011-04-02]
Version 0.6.4                               "Spring is sprung"

This version of aptitude requires apt 0.8 and will not build against
earlier releases.

- Security fixes:

* [curses]: Fixed an arbitrary overwrite triggered by saving changes
              in the hierarchy editor, if the current user's home
              directory couldn't be determined. (Closes: #612034)

- Crashes and serious errors:

* [all]: Don't crash when apt-xapian-index isn't installed. (Closes: #588089)

- Interprets "~" as "?name(~)" instead of "?term(~)"

- If the Xapian index isn't available, attempts to mimic its
        behavior to a first approximation: not perfectly, but enough
        to make ?term and ?term-prefix do something sensible.

* [all]: Restore aptitude's old treatment of the auto flag, meaning
           that instead of clearing the flag when the user asks to
           upgrade a package, we leave it set.  Worked around a change
           in apt's behavior by forcibly preserving the auto flag's
           setting regardless of what pkgDepCache::MarkInstall thinks
           is right this week. (Closes: #622719)

- New features:

* [curses]: Add a "source" grouping policy that groups packages by
              their source package name.  Thanks to Thadeu Lima de
              Sourza Cascardo for the patch, sorry it took so long to
              apply!  (Closes: #497206)

- Minor bugs:

* [all]: Fixed the debug logging code to output TRACE-level
           messages.

* [all]: Fixed the debug logging code to properly allow log levels
           to be disabled.

* [all]: Fixed the resolver cost levels for installs and upgrades.

- Internal changes:

* [all]: Include the current time and thread ID in all debug log
           messages.

* [cmdline]: Refactor terminal handling to simplify some of the
               tests.

* [qt]: Added the beginning of a Qt frontend, thanks to SoC 2010
          student Piotr Galiszewski.  Not really in a usable state
          yet.

* [all]: Fixed build errors with gcc 4.6 (Closes: #624948)

- Cosmetic and UI bugs:

* [cmdline]: Overhaul how download progress is displayed at the
               command-line.  Fixes problems on large terminals and
               should provide less glitchy behavior in general.

- Build system changes:

* [all] Use $(srcdir) whenever $(wildcard) is used, so wildcarded
          files get picked up even when the build directory is not the
          source directory.

* [all] Build src/generic/util before src/generic/apt (which depends
          on it).

* [all] Multiple fixes to get VPATH builds working properly.

* [doc]: Added a doc-fo target that builds (very rough) PDF
           documentation if you have fop installed.

* [gtk] If the GTK+ frontend isn't built, don't try to build tests
          that require it.

Version 0.6.3                               "Sunlight, moonshadow"

This version of aptitude fixes some crashes that occurred when
  exiting the program and overhauls how progress is displayed from the
  command-line.

aptitude now requires google-test and google-mock; it will work with
  newer versions of libept and older versions of boost; it no longer
  requires log4cxx.

- New features:

* [cmdline] Modified the command-line progress counters so that
              they're erased when they complete instead of leaving
              cruft behind.

The old behavior and appearance can be recovered by
              Aptitude::CmdLine::Progress::Retain-Completed and
              Aptitude::CmdLine::Progress::Percent-On-Right to "true".

- Crashes and serious errors:

* [all] Ditching log4cxx will hopefully fix some of the crashes on
          exit that people were seeing.

- Cosmetic and UI bugs:

* [cmdline, curses] Fixed the display of the archives associated
                      with a version so that duplicated archive names
                      are never displayed.

- Internal changes:

* [gtk] Started working on a redesign of the GTK+ interface, both
          internal and external.  The internal half involves
          refactoring the code to better separate logic and
          presentation and to improve testability and code reuse.  The
          external half adds the groundwork for a redesign of how the
          UI is arranged at the top level.

This code is very incomplete and currently disabled by
          default.

* [cmdline] The progress changes noted above included some
              refactoring to make the command-line interface easier to
              unit test.  In particular, I created a terminal
              abstraction that could be stubbed out for the purposes
              of testing.  Currently this is only used for the
              progress code, but it's likely to become more widely
              used as time goes on.

- Changes for build dependencies:

* [all] Stopped using log4cxx in favor of a homegrown module.

We're really only using it for debug output, so its most
          powerful features aren't useful for aptitude.  At the same
          time, it appears to be behind some of the crashes on exit
          that users have reported, and it's never really integrated
          well into the program (the initialization process has always
          been a hack).  The new code is much better suited to
          aptitude's requirements.

* [all] Added appropriate configure checks and conditionalization to
          support building against either the current ept release or
          the upcoming release. (Closes: #581009)

* [all] Write a proper configure check to detect the calling
          convention used by boost::fusion::fold(); don't require
          Boost 1.42 any more.

- Build system changes:

* [all] Added a build system based on scons.  scons supports fully
          parallel builds and variant builds without reconfiguration,
          which should speed up the build process significantly on
          multi-core machines.

* [all] Switch from automake 1.9 to automake 1.11.

[2010-04-21]
Version 0.6.2.1                             "I didn't know it was a
                                             real zebra!"

- Crashes and serious errors:

* Fixed a crash caused by being insufficiently careful about NULL
    pointers in the resolver. (Closes: #578344)

* Boost 1.42 changed the order of arguments to fusion::fold(),
    breaking aptitude.  As an interim measure, I have modified
    configure to require 1.42 or higher, and fixed the argument order.
    The correct long-term fix here is to do a feature test to see
    which order fold expects its arguments in.

- Backwards compatibility fixes:

* Restored the "conflict" safety level/tier.

* Fixed a bug that meant that the old configuration option names
    (*-Tier instead of *-Level) could only be used to increase safety
    levels, not to decrease them.

- Internal changes:

* Change the incremental_expression subsystem of the resolver to be
    fully robust against NULL pointers and write unit tests for it.

* Reduced the number of explicit dependencies on log4cxx (using
    indirection), in case I decide to resolve the random crashes it
    causes by switching to some other framework or rolling my own.

[2010-04-18]
Version 0.6.2                               "A costly proposition"

- New features:

+ [all] Resolver tiers are dead, long live resolver costs.

The resolver now supports a flexible system of multi-leveled
          costs, in place of the fairly rigid tiers of previous
          releases.  The default behavior emulates how tiers worked,
          but the resolver can also be configured with custom cost
          vectors by setting Aptitude::ProblemResolver::SolutionCost
          to something like this:

canceled-actions + 2*removals, ignored-recommends, installs

That says to minimize the number of packages kept at their
          current version plus twice the number of removals (i.e., a
          removal counts for two keeps).  Within that group, ties are
          broken by looking at the number of Recommends that were
          ignored, and within that group, ties are broken by looking
          at the number of new packages the resolver wants to install.

In addition to custom cost vectors, resolver hints can be
          used to create completely custom costs.

See the reference manual for full details.

This is not optimized and I expect that pushing it to the
          limits will show off all sorts of exponential explosions.
          Have fun!

+ [cmdline] Implemented an "aptitude versions" command that I've
              been kicking around for a while, to display and search
              for individual package versions.  Documented in the
              manpage, but here are some highlights:

$ aptitude versions apt
                i   0.7.25.3                         unstable     500
                p   0.7.26~exp3                      experimental 1

$ aptitude versions '^apt$ ?installed'
                Package apt
                i   0.7.25.3                         unstable     500

$ aptitude versions xserver-xorg udev
                Package udev:
                i   151-2                                         100
                p   151-3                            unstable     500

Package xserver-xorg:

                p A 1:7.5+5                          unstable     500

$ aptitude versions --group-by=source-package '?name(aptitude)'
                Source package aptitude:
                i   aptitude 0.6.1.5-2                            100
                p   aptitude 0.6.1.5-3               unstable     500
                i   aptitude-dbg 0.6.1.5-2                        100
                p   aptitude-dbg 0.6.1.5-3           unstable     500
                i   aptitude-doc-cs 0.6.1.5-2                     100
                p   aptitude-doc-cs 0.6.1.5-3        unstable     500
                (... many more lines of output snipped ...)

- Crashes and serious errors:

+ [cmdline] Don't crash if the user sets a rejection at the internal
              command-line via package name and version rather than
              using the new pick-by-numbers UI. (Closes: #567242)

+ [cmdline] Don't crash if the user asks to see information about a
              removal.

+ [cmdline] Don't crash in "aptitude changelog" when the package
              given on the command-line doesn't have a valid version
              (Closes: #576318).  Thinks to Dmitry Semyonov for the
              patch.

- Cosmetic and UI bugs:

+ [curses] Don't leave a download progress bar hanging around after
             downloading a changelog. (Closes: #566205)

- Internal changes:

+ [all] Replaced mktemp() with a custom function doing a similar
          thing (albeit with slightly better randomness).  This
          eliminates the spurious linker warning I've been ignoring
          for five years: the linker has no way to know that I only
          use mktemp() to create names in a mode 0700 directory, which
          is about the only way to use it safely.

[2010-01-20]
Version 0.6.1.5                             "All around the dependency bush,
                                             the monkey chased the weasel..."

- Crashes and serious errors:

+ [all] Changed the default resolver configuration so that removals
          and "safe" actions are grouped together.  Without this
          change, aptitude was being too conservative and failing to
          solve simple upgrades. (Closes: #565867)

The safe-upgrade resolver is unaffected by this change,
          since it uses explicit constraints to prevent removals from
          being installed.

- Cosmetic and UI bugs:

+ [test] Eliminated a spurious error message that was being printed
           by the cppunit unit tests.

+ [curses] Fixed the progress display and error reporting for
             changelog downloads.

- Documentation:

+ [doc] Added a note in the manpage explaining the principles of the
          Linux command-line to hopefully forestall future bug reports
          telling me that the manpage for "aptitude search"
          contradicts the user manual.  (Closes: #566003)

[2010-01-17]
Version 0.6.1.4                             "You can't take the sky from me."

- New features:

+ [gtk] The status of each changelog download is now displayed in
          the space where that changelog will appear.

+ [cmdline] When aptitude displays a resolver solution, it now
              displays a number next to each entry in the solution.
              This number can be used to manipulate the corresponding
              entry (for instance, to reject it or to view information
              about it).  This makes it much more convenient to use
              the command-line resolver interactively.

- Crashes and serious errors:

+ [all] Be paranoid about the sign of file offsets (on some
          architectures they're apparently signed). (Closes: #557212)

+ [all] Fix various include and compilation errors revealed by the
          new version of g++ being stricter. (Closes: #531687, #560517)

+ [all] Use pthread_sigmask() instead of sigprocmask() on startup to
          avoid problems on architectures where sigprocmask() behaves
          poorly in multi-threaded processes. (Closes: #559980)

+ [gtk] Fix a startup crash caused by not properly protecting the
          call to Glib::thread_init(). (Closes: #555120)

- Cosmetic and UI bugs:

+ [cmdline] Document the flags that are shown after packages in the
              preview.

+ [cmdline] Instead of showing broken packages in their own group,
              show them in the group they would normally appear in but
              with a "b" flag.

It was somewhat confusing that packages which were being
              installed but had broken dependencies showed up in the
              "broken" section instead of the "install" section.
              Packages that are unchanged and have broken dependencies
              won't show up in the preview any more, but they will
              show up just below it, in the list of packages with
              broken dependencies.

+ [all] Eliminate spurious error messages from log4cxx. (Closes: #557150)

- Internal changes:

+ [all] Download changelogs using the new internal download queue,
          not the download_manager system.  Fixes random crashes at
          shutdown.

+ [gtk] Wrote the first draft of some harness code that will
          underpin a redesign of the main window.  Currently this is
          unused.

[2009-11-19]
Version 0.6.1.3                             "Too many cooks put lots of
                                             beans in the soup."

- Build system fixes:

+ [doc] Fixed the Makefile for the Spanish translation of the
          documentation so that it honors DESTDIR.

[2009-11-19]
Version 0.6.1.2                             "I think I can, I think I can..."

- Crashes and serious erroors:

+ [all] Modified the new temporary file module so that it doesn't
          rely on the order in which global destructors run.  This was
          causing an abort when the program exited if it was built
          with optimizations.

- Internal changes:

+ [test] Wrote an additional unit test verifying that the program's
           temporary directory is really deleted when it exits.

[2009-11-19]
Version 0.6.1.1                             "Again with the bug-writing."

- Crashes and serious errors:

+ [test] Fixed the test code to actually compile against the new
           temp API (major oops there).

+ [all] Fixed the temporary directory code to create directories in
          $TMPDIR rather than ".".

[2009-11-18]
Version 0.6.1                               "Instant toll logging."

- New features:

+ [gtk] Support for automatically downloading screenshots from
          screenshot.debian.net.  Eventually the screenshots will
          probably show up in a few more places, such as the update
          preview and package lists (but this will require careful
          coding to only download screenshots that are visible).

- Internal changes:

+ [all] aptitude now has a generic global download queue.  This is
          actually implemented with the apt download queue object, but
          it runs all downloads in the background, integrates with
          aptitude's download cache, and provides support for getting
          status information on individual downloads and canceling
          them.

This new queue is used to implement screenshot support.

+ [all] Overhauled how temporary files are created.  aptitude will
          now create only one entry in $TMPDIR, and it will make a
          stronger effort to delete all its temporary directories when
          it exits normally.  Abnormal exits (i.e., signals) will
          still leave cruft behind, but at least it's only one file
          and not dozens per run.

- Crashes and serious errors:

+ [all] Don't support trying to block the foreground thread while
          dependencies are solved; doing so is very deadlock-prone and
          was causing deadlocks in practice.

+ [all] Fix several places where the "why" code dereferenced version
          iterators without checking whether they were valid, causing
          a crash. (Closes: #546446)

+ [gtk] Fix several crashes in the resolver tab caused by trying to
          generate tooltips using invalid version objects.

+ [gtk] Properly disconnect signals from the background thread in
          the dashboard tab, instead of occasionally crashing when one
          is delivered after they should have been disconnected.

+ [gtk] Fix a potential deadlock that could have occurred if the
          main thread posted lots of thunks to itself.

- Minor bugs:

+ [all] The resolver will now ignore recommendations that are
          already unresolved on the system, rather than trying to fix
          them every time any dependency needs to be solved.
 	  (Closes: #556042)

+ [curses] Fix becoming root with the "su" protocol. (Closes: #552471)

- Cosmetic and UI bugs:

+ [all] Correct how we decide when the resolver is out of solutions.

+ [all] Work around a spurious error message generated by apt.
          (Closes: #526661)

+ [cmdline] The message that no packages are being installed,
              removed or upgraded is more accurate now.

+ [cmdline] Another preview is shown after the resolver runs even if
              -y was passed on the command-line.

+ [cmdline] Exit without prompting if the user tells the dependency
              solver to cancel all of their changes. (Closes: #556866)

+ [gtk] Fix a typo in one of the resolver tab's tooltips.

+ [gtk] Fix the resolver tab to only show a new solution when the
          user explicitly asked for one.

[2009-10-25]
Version 0.6.0.1                             "Who's laughing now?"

- Build system fixes:

+ [all] Actually distribute the auxiliary data for the unit tests.
          Hopefully this means that the unit tests can actually pass
          in the distributed tarfile.

[2009-10-25]
Version 0.6.0                               "Stick a fork in it,
					     it's done."
- Internal changes:

+ [all] The file cache now supports storing the last modification
          time of cached files.  Currently this isn't used (changelogs
          are assumed to be up-to-date anyway), but future code will
          need this.

+ [gtk] Factored out the common parts of the background threads that
          handle changelog downloading into a generic utility class.

- Minor bugs:

+ [all] Load the download cache in apt_init() instead of
          apt_preinit().  Avoids complaints from log4cxx if there are
          errors, and also ensures that we have a download cache even
          if the apt cache was closed and reopened.

+ [all] Add some missing #includes that showed up when NLS wasn't
          enabled.

- Build system fixes:

+ [all] Don't include files in POTFILES.in that aren't distributed.
          Hopefully this will prevent the unnecessary junk that was
          getting into the Debian diff.

[2009-10-12]
Version 0.5.9rc4                            "Trust me, you don't want
                                             to know about the spork."

- New features:

+ [all] The test to see whether a changelog is in aptitude's
          download cache now takes place in a background thread.

+ [gtk] When generating the upgrade summary, aptitude caches a
          parsed version of the portion of each changelog that's
          displayed.  This makes the changelogs show up much faster
          and with a lot less system load.

+ [gtk] The second tab in the upgrade view now displays information
          about the currently selected package, rather than its full
          changelog.

+ [gtk] "aptitude --version" prints the versions of GTK+ and GTK--
          that it was compiled against.

- Crashes and serious errors:

+ [all] Fix how the background dependency solver thread communicates
          with the foreground thread to eliminate at least one
          deadlock.

- Cosmetic and UI bugs:

+ [curses] Don't print a spurious warning if we get --no-gui when
             the GTK+ frontend was compiled out. (Closes: #550727)

- Build system fixes:

+ [gtk] Make "./configure --enable-gtk" enable GTK+ instead of
          disabling it.

Version 0.5.9rc3                            "The stars, like little
                                             starry things..."

- New features:

+ [cmdline] Package versions can be chosen by codename as well as by
              archive. (Closes: #547707)

+ [all] Not exactly a new feature, but reverted from
          dpkg-parsechangelog to parsechangelog: both of them require
          extra dependencies, and parsechangelog is faster. (Closes:
          #546280)

- Crashes and serious errors:

+ [all] Don't crash if the Xapian database fails to load.  (Closes:
          #512998)

+ [all] Recognize --no-gui even in non-GUI builds, so switching to
          root can just always pass it. (Closes: #546406)

+ [all] Don't discard errors after dpkg fails. (Closes: #548879,
          #548889)

+ [gtk] Don't crash when displaying the file list of a package
          that's not installed.

- Cosmetic and UI bugs:

+ [curses] Block SIGWINCH by default so that cwidget can sigwait()
             on it. (Closes: #547212)

+ [cmdline] Mention build-dep in "aptitude help". (Closes: #547151)

+ [cmdline] Consistently use a full-stop at the end of "--help"
              lines.

+ [cmdline] Fix an incorrect message that stated that a package was
              not installable, rather than that it was not going to be
              installed.

+ [cmdline] Make --arch-only do what it should instead of the
              opposite. (Closes: #547266)

+ [gtk] Make the "hold" command hold packages instead of deleting
          them. (Closes: #549897)

+ [gtk] Use a single thread for all changelog downloads, to avoid
          spawning as many instances of parsechangelog as there are
          changelogs.

I really should move the extraction of changelogs from the
          cache to a background thread as well; it takes ages to
          extract every last changelog if there are a lot, and I
          should be able to start parsing them as soon as the first
          one is extracted.

- Documentation:

+ [doc] Mention Get-Root-Command in the section on "becoming
          root". (Closes: #548657)

+ [doc] Correct the default value of Get-Root-Command to match the
          code. (Closes: #550057)

[2009-09-09]
Version 0.5.9rc2                            "Over five served."

- Crashes and serious errors:

+ [all] Fix a bug in the logic to filter package actions so that
          only actions initiated by apt's greedy resolver are
          affected, rather than all actions.

[2009-09-08]
Version 0.5.9rc1                            "The only way to win
                                             is not to play."

First release candidate for 0.6.0.  Due to the length of time it's
taken me to prepare this and to the new Debian release cycle, I'm
releasing 0.6.0 before the GTK+ interface is really complete; it's
still in an experimental state.  However, several of the other changes
in this release should really be rolled into the mainline before the
Debian release (particularly the improvements and optimizations to the
dependency solver).

This version disables the full-text Xapian search by default, although
it can still be accessed via ?term().

Version 0.5.9rc1

- New features:

+ [all] Internal file cache for auxiliary downloads, based on the
          binary file engine SQLite and the Boost zlib wrapper.  This
          will substantially speed up the GTK+ interface's startup
          time when it's just downloading the same thirty changelogs
          it was showing before, and will be even more helpful once
          aptitude can show screenshots.  Hopefully it will also
          reduce the load on the Debian network infrastructure.

+ [all] aptitude now uses the new hooks in apt to prevent the greedy
          resolver from removing packages or breaking holds.

(Closes: #177374, #205049, #374353, #376802, #406506,
                   #430816, #434731, #442420, #452589)

+ [all] aptitude now uses dpkg-parsechangelog to parse changelogs
          instead of parsechangelog, courtesy of Frank Lichtenheld's
          patch in 2007.  This means that it no longer requires
          libparse-debianchangelog-perl to show changelogs.

+ [all] "aptitude update" now honors the configuration options
          APT::Get::List-Cleanup and APT::List-Cleanup.
	  (Closes: #448958)

+ [cmdline] "aptitude safe-upgrade" now supports listing extra
              actions on the command-line, just like "install",
              "remove", etc.  If any actions are listed, then only the
              given actions are performed (the blanket upgrade is
              skipped).  Packages with no qualifications give a list
              of the packages that should be upgraded; if they aren't
              installed or aren't upgradable, they're ignored.

+ [curses] The commands to clean the package cache and to delete
             obsolete files now support automatically becoming
             root. (Closes: #492832)

- Crashes and serious errors:

+ [all] Fix some crashes that occurred when viewing dependency solutions.

+ [all] Make "aptitude update" correctly clean up the list
          download directories.  (Closes: #507603)

+ [all] Disable Xapian full-text search by default; it's still
          available via the ?term pattern.  Feedback on this "feature"
          was uniformly negative; it seems to be flaky and not very
          useful.  Maybe it would be useful with more work, but it
          won't be ready for Squeeze.  (Closes: #527540, #538198,
          #514625)

+ [cmdline] Fix a bug that caused lots of extra "unresolved
              recommendations" to be displayed in dependency
              solutions.

+ [curses] Fix a crash on exit that was caused by having dangling
             boost::flyweight objects when the global destructor was
             invoked (arguably this is a bug in Boost; we might want
             to consider moving away from flyweights for this reason).

+ [curses] The auto-su-to-root code now passes --no-gui, so it
             should actually work again (rather than popping up a
             graphical UI).

- Cosmetic and UI bugs:

+ [all] Fix some corner cases in the serialization of search
          patterns, such as the new "enhances" dependency type.

+ [curses] Hopefully fix pattern-based grouping in the curses UI.

+ [curses] Add descriptions of the new ftp sections to the default
             sections file (thanks to Miroslav Kure).

+ [gtk] Make more of the UI translatable (thanks to Miroslav Kure).

+ [gtk] Don't attempt to translate the empty string when displaying
          the state of a package that's unchanged.

- Documentation:

+ [doc] Document that full-upgrade and safe-upgrade take extra
          actions on the command-line. (Closes: #268696)

+ [doc] Document that the "standard" apt options should be used
          instead of Keep-Suggests and Keep-Recommends.

[2009-07-20]
Version 0.5.3                               "The Aardvark Contingency"

This version of aptitude now requires GTK+ 2.16 or greater and GTK--
2.16 or greater.

- Crashes and serious errors:

+ [gtk] Don't crash when displaying a solution that cancels the
          installation of a package. (Closes: #525898)

- Internal changes:

+ [all] Rewrote the resolver code to trade memory for time.  Large
          dependency problems should be processed in about 20% of the
          time that previous versions took.

- Cosmetic and UI bugs:

+ [gtk] Some redesigns to the GTK+ UI (Thanks to Arthur Liu).

+ [gtk] Display package short descriptions in the resolver tab.

+ [gtk] Display the search progress bar behind the text of the
          search term (requires GTK+ 2.16 or greater).

- Translation updates:

+ Asturian (Closes: #521558)
  + Finnish (Closes: #531582)
  + Spanish: added translation of the user's manual.

[2009-04-26]
Version 0.5.2.1                             "Albatross!"

- Crashes and serious errors:

+ Don't crash when tabs are closed from the menu or using Ctrl-W.

- Internal changes:

+ [gtk] Always use trampolines (via the main loop's idle handler) to
          delete tabs, to hopefully avoid bad interactions when a tab
          is closed as a side effect of some other action.

- Cosmetic and UI bugs:

+ [gtk] Eliminated some warnings that were caused by modifying a
          tree model while iterating over its selection list.

+ [curses] Work around some buggy terminals so that the progress bar
             doesn't get truncated or corrupted. (Closes: #455220)

+ [cmdline] Change the "last-package" summary mode to
              "first-package".  aptitude prints the package that's
              selected by this option at the beginning of a chain, so
              it seems counterintuitive to me to call it the "last"
              package.

+ [cmdline] Renamed the configuration option
              "Aptitude::Why-Display-Mode" to
              "Aptitude::Show-Summary", to match the command-line flag
              that it corresponds to (--show-summary).

+ [cmdline] Removed a stray space in the output of "aptitude why".

- Documentation:

+ [doc] Document --show-summary and Aptitude::CmdLine::Show-Summary.

+ [doc] Use rsvg instead of Inkscape to convert svg diagrams to png
          files for the time being.  Also cropped rsvg to the drawing
          boundaries.

+ [doc] Add search-tier-diagram.svg to the distributed .tar.gz file.

[2009-04-22]
Version 0.5.2                               "Ramparts of the Dawn"

This release merges in the work that was done on the lenny branch of
the program but not the post-lenny one (mostly translation work).

KNOWN BUGS:

+ Ctrl-W should close a tab, but instead it crashes the program.  Do
    not press Ctrl-W and you will be happier.

+ When you reject or accept a resolver choice, the corresponding row
    in the solution might not update to reflect your change.  If you
    switch to another solution and back, it will update correctly.

- New features:

+ [all] aptitude now uses liblog4cxx to provide diagnostic logging
          of much of the program.

+ [all] The aptitude dependency solver now supports a "tiered
          search".  Hopefully this will make dependency resolution
          more predictable and allow more meaningful configuration.
          In particular, removals are not attempted until all
          solutions involving only keeps, installs and upgrades are
          exhausted, and solutions involving versions that aren't the
          default candidate are deferred until removals are exhausted.

See the user's manual for details.

Closes: #514820, #514930, #524221, #473296

+ [gtk] The resolver tab has been completely overhauled.  It now
          supports all the features of the backend dependency solver,
          and it has an interface that is much more suitable for a
          GTK+ program.

+ [gtk] The dpkg tab now attempts to detect when something is
          waiting for input, by keeping track of how long it's been
          since dpkg sent a status message.  When input is available,
          the "view details" button is flashed to hopefully get the
          user's attention.

+ [gtk] The procedure for upgrading has been streamlined.  aptitude
          computes an upgrade in the background automatically using
          the same algorithm that backs "safe-upgrade".  The user can
          either accept the solution or try to fix the remaining
          dependencies manually.

+ [cmdline] Added a new command-line option, "--show-summary", to
              the "why" command-line action.  This option causes
              aptitude to show a brief list of the first package in
              each dependency chain that would have been displayed.
              So combined with the "-v" option, you can easily get a
              list of all the manually installed packages that require
              a given package.

+ [gtk] When the user clicks on a package in the dashboard's list of
          upgrades, the changelog display automatically scrolls to
          that package.

+ [gtk] Some common notifications are now marked with the icon of
          the task they're performing.

+ [gtk] Initial support for incremental search (currently you have
          to click the "incremental" toggle button to enable it).

+ [gtk] Ctrl-PageDown and Ctrl-PageUp, or F7 and F6, now switch to
          the next or previous tab, respectively.

+ [gtk] A link now exists below the package description to open all
          the other packages from the same source package.

+ [all] The aptitude dependency resolver now continues searching for
          a few steps after it finds a solution, in the hope that it
          can find a better one. (Closes: #482825)

+ [all] The aptitude dependency resolver now adds a bonus to the
          default apt resolution for a dependency (that is, the first
          non-virtual package listed).  The default bonus is 400 and
          it may be configured via
          Aptitude::ProblemResolver::DefaultResolutionScore.

+ [all] Setting the environment variable APT_ROOTDIR to a directory
          name will cause aptitude to use the given directory as the
          root for the purpose of locating apt files.

- Crashes and serious errors:

+ [gtk] Don't crash in the dependency chains tab. (Closes: #514714)

+ [gtk] Don't crash when the user views the information tab of a
          virtual package.

+ [all] Fixed some serious inefficiencies in the algorithm used by
          safe-upgrade.  It's still a bit slow on very large upgrades,
          but not as ridiculously slow as it was before.

+ [all] Fixed a bad interaction between the dependency solver and
          reinstatement of unused packages, which could cause a
          situation where a "solution" from the solver would actually
          lead to broken dependencies, due to a conflict declared on
          the newly reinstated package. (Closes: #522881, #524667)

- Cosmetic and UI bugs:

+ [gtk] Changelogs are now downloaded and parsed in the background.
          aptitude still sets the download up in the foreground, and
          this can take a long time if there are lots of available
          upgrades.

+ [gtk] A background thread is used to find the packages that match
          a search pattern and to build the list of matching packages
          for display.

+ [gtk] Some work on the download screen, although more is needed.

+ [curses] Don't warn the user about removing an Essential package
             if they're just purging the configuration files of one
             they removed already.  (Closes: #513472)

+ [curses] Don't compute an excessive amount of "why" information
             every time a package is selected.  Should make the curses
             interface much less sluggish. (Closes: #516296)

+ [cmdline] Add a missing newline in the error message that
              "aptitude why" prints if it has no arguments.
	      (Closes: #514676)

+ [cmdline] Fix some badly formatted messages that are displayed
              when a build dependency can't be installed: they were
              missing punctuation and newlines. (Closes: #492615)

+ [cmdline] Make the warning asking the user to use safe-upgrade
              instead of upgrade a bit clearer.

+ [cmdline] Always display [held] next to the state of held
              packages.

+ [cmdline] Pre-compute the column sizes needed to display "why", so
              that columns don't wrap in Stupid Places[tm].
	      (Closes: #516389)

- Minor bugs:

+ [all] The dependency resolver's scoring of full package
          replacement was not behaving as intended in the corner case
          that the package was replaced due to a virtual package it
          provided, and some other version of the replaced package
          didn't provide that virtual package.  The intent was to give
          the non-providing package a bonus, but instead the versions
          that got replaced were getting a bonus (more or less
          negating the whole point of the full replacement score).

+ [all] The resolver should now more correctly obey approval
          constraints set by the user (solutions that were previously
          rejected and aren't rejected any more can be returned).

- Internal changes:

+ [all] The dependency resolver now supports "hypothetical
          reasoning": it can calculate a solution to a dependency
          problem from a starting state that isn't the "live" state of
          the package cache.  This is used, for instance, to compute
          an upgrade before any packages are marked for upgrade.

+ [all] Implemented support in the dependency resolver for
          propagating knowledge about dead-ends up the search tree.
          Currently disabled as it turned out to greatly increase the
          memory and CPU overhead of a search without significantly
          decreasing the number of steps needed.

+ [all] The dependency resolver now stores solutions as sets of
          "choices" rather than explicitly maintaining several lists
          for the different types of choices a solution can contain
          (for instance, installing a version vs leaving a Recommends
          unresolved).  This makes things a bit cleaner and should
          make it easier to add new types of choices if that turns out
          to be useful.

+ [gtk] The Glade file now stores each tab as a separate top-level
          widget, which makes it a lot easier to edit and add tabs.

- Documentation:

+ [doc] Improve the documentation of --purge-unused.

+ [doc] Improved documentation of the resolver (in addition to
          documenting the new features).

[2009-01-18]
Version 0.5.1                               "One step at a time"

- New features:

+ [all] New match term: ?term-prefix(term).  This is like ?term(),
          but it searches the Xapian database for any term which is an
          extension of ?term.  For instance, ?term-prefix(hour)
          matches any package that contains the terms "hour",
          "hourglass", "hourly", etc.

+ [all] If the user asks for the changelog of a version of a package
          that's currently installed, aptitude will use the local copy
          instead of downloading a new copy off the network.  If the
          local copy can't be used for some reason, aptitude will fall
          back to downloading a copy.

+ [all] Implemented resolver hints: you can now place options in
          apt.conf that control how the aptitude resolver treats
          particular packages.  For a full discussion see the user's
          manual, but here is a flavor:

Aptitude::ProblemResolver::Hints
          {
            "reject pulseaudio";          // Prevent the "pulseaudio"
	    	    			  // package from being installed
					  // by the aptitude resolver.
            "approve ?name(emacs[0-9]*)"; // Always choose emacsNN over
                                          // any alternatives.
            "300 ?true /unstable";        // Give a 300-point bonus to
	    	       			  // any version in the
					  // "unstable" archive.
          };

Currently these hints do not influence the choices made
          by the "immediate" dependency resolver (the one that runs as
          soon as you mark a package for installation).

+ [gtk] aptitude now parses the dpkg status pipe, so it can show a
          progress bar while dpkg is running.  Closing the terminal
          tab does not terminate the install; only destroying the
          progress bar does that.

+ [gtk] The search entry box's background will turn slightly red if
          the current text is not a valid search pattern.

+ [gtk] If the user enters an invalid search pattern into the search
          entry box, the error will be shown below the box (rather
          than being shoved onto the apt errors pane).

+ [gtk] aptitude prompts for confirmation before killing a download
          or a dpkg process.  The download prompt might be
          superfluous, but considering the possible side-effects of
          killing off dpkg, that prompt will remain for the
          foreseeable future.

+ [gtk] aptitude will print a message to its embedded terminal
          before and after running dpkg.

+ [gtk] A drop-down box of package filters is available under the
          text box where searches are entered.  This lets you quickly
          filter a list of packages by some common criteria (showing
          only packages that aren't installed).

+ [gtk] The "automatically installed" flags of packages can be
          toggled from the Package menu or from buttons in the
          description pane.

+ [gtk] Undo -> Undo works.

+ [gtk] When viewing a dependency solution, you can choose to see
          the actions in their "logical" order (equivalent to typing
          "o" in the curses front-end).

+ [gtk] In the version information tab (the one you get by
          double-clicking a package), selecting a different version in
          the list of versions causes information for that version to
          be shown instead.

+ [gtk] You can now change which columns are visible in a package
          list by selecting View -> Edit Columns... or by clicking the
          "..."  column heading.

+ [gtk] New package list column: "automatically installed".

Each value in this column is displayed as a check-box, where
          the box is checked if the package is automatic.  The
          check-box can't currently be clicked because I'm worried
          that people would click it by accident while trying to
          select a package.  Most likely the rendering will be changed
          in the future to look less "clickable".

+ [gtk] New package list column: "archive".

- Crashes and serious errors:

+ [gtk] Fix several crashes, including one at start-up, that were
          caused by some unusual package states.

- Minor bugs:

+ [cmdline] "aptitude why-not" no longer crashes when the final
              argument is a virtual package.

+ [gtk] The "Download started" row in the Downloads page is no
          longer shown.

+ [gtk] The dependency chains tab no longer misses some chains that
          "aptitude why" would show.

+ [gtk] Fix buffer problems due to sprintf by using aptitude's safer
          variant of that function. (Closes: #511559)

+ [gtk] When extracting just the part of a package's changelog that
          corresponds to versions that are newer than the currently
          installed version, truncate the changelog as soon as we see
          the version numbers go "backwards" -- that is, as soon as
          the previous version in the changelog is "newer" than the
          current version.

This is important because some packages changed their
          version scheme over time.  For instance, g++-4.2 lost its
          epoch in 2004 when the package name changed.  But that
          doesn't mean that those earlier versions of the package
          should be displayed when we want to display the log for
          today's upgrade!

- Cosmetic and UI bugs:

+ [all] The --help output now mentions --gui and --no-gui.

+ [gtk] Many tweaks and improvements to the appearance of the UI;
          particular thanks to Luca Bruno for his patches.  The
          program looks a lot "nicer" overall as a result of his work.

+ [gtk] The RC style "tiny-button-style" is used for tab close
          buttons.

+ [gtk] Use the "yes" icon (a green sphere) to indicate that a
          package is installed and OK.  This is far more recognizable
          for me (dburrows) than the hard disk icon we were using
          before.

+ [gtk] Not-yet-implemented menu options produce a "not implemented"
          message.

+ [gtk] Some menu items are disabled if they don't apply to the
          "currently selected object".

+ [gtk] When the user performs an action on several packages at
          once, any packages they install will be marked as manually
          installed, and package states won't change to fulfill
          dependencies if those dependencies are already satisfied by
          the selected actions.

For instance, suppose that the user selects A, B, and C for
          installation.  A depends on "D | B", and B depends on C.
          Previously aptitude might decide to install D to fulfill A's
          dependency, and would mark C as automatically installed
          because of B's dependency.  Now, just the three selected
          packages will be installed, and they will all be marked as
          manually instsalled.

- Documentation:

+ [doc] Wrote a new section of the documentation describing the
          various dependency resolution mechanisms in aptitude.  This
          includes the old section on resolving dependencies, but also
          describes the immediate resolver and how to configure the
          full resolver using resolver hints.

- Internal changes:

+ [gtk] Redesigned the dpkg terminal creation code to make it
          cleaner and more maintainable.

+ [gtk] Redesigned the code for the buttons in the package
          description pane.

+ [gtk] Stopped using random bits of the glade file as templates for
          other GUI elements, in preparation for making each tab a
          separate top-level widget in the file.

- Translation fixes:

+ Fix how ngettext is used so that the plurals can be properly
    translated.  (Closes: #505675)

+ Slovak (Closes: #505676)

Version 0.5.0                               "Wheee!"

This version introduces the GTK+ frontend.  Thanks are due to Obey
Arthur Liu for providing code, ideas and energy to the project, and to
Google for funding his work through their Summer of Code program in
2008.

This is an EXPERIMENTAL, DEVELOPMENT release.  It can be used for
package management, but there may be bugs, there are probably places
that need improvement, and it is certainly incomplete.

- New features:

+ Integrated the GTK+ frontend written by Obey Arthur Liu for the
    2008 Google Summer of Code.  To manually suppress the GUI, run
    "aptitude --no-gui" or set the option "Aptitude::Start-Gui" to
    false.

+ Added Xapian support.  Unadorned strings in search patterns now
    search the apt Xapian database built by Enrico Zini.  There is
    also a new search term ?term that does the same thing.

+ Added the command-line option "--show-resolver-actions" to display
    why aptitude made the decisions it did in "aptitude safe-upgrade".

- Known Regressions:

+ Incremental searching in the curses frontend is made much less
    useful by introducing Xapian.  It still works, but because Xapian
    searches don't find substrings, the search will fail to match
    anything until you finish typing the entire search string.

+ Documentation for the GTK+ frontend has not yet been written.

Version 0.4.11.11                           "And the moon be still as bright"

This is purely a translation release for Debian lenny.

- Translation fixes:

+ Catalan (Closes: #499464)
  + German (Closes: #500444)
  + Greek (Closes: #498583)
  + Italian
  + Romanian (Closes: #502413)

[2008-09-05]
Version 0.4.11.10                           "Upon the empty winds of time"

- Bug fixes:

+ Serious bugs:

* Never, ever remove an Essential package from the curses UI
      without asking the user first.  I chose a very simple
      implementation for this patch because of the pending release of
      lenny, and so users who are removing Essential packages will get
      prompted twice.  But I feel this is better than occasionally not
      prompting at all; it will be cleanup up later, once lenny is
      out.

+ Minor bugs:

* Fix displaying the section descriptions in non-UTF-8 locales.
      (Closes: #483464)

* Add the ?task search term, which was documented in some areas
      but not others, and wasn't actually implemented due to an
      oversight.

- Documentation bugs:

+ A whole pile of minor improvements suggested by "jidanni".
    (Closes: #497374, #497340, #496726, #471347, #496719, #496729,
    #496732, #497333, #497336, #497726, #497969)

+ Give the right name for the preview limit configuration option:
    it's Aptitude::UI::Preview-Limit, not Aptitude::Preview-Limit.

+ Generate the HTML documentation in a UTF-8 encoding.

- Translation fixes:

+ Brazilian Portuguese (Closes: #496613)
  + Czech (Closes: #497287)
  + Dutch (Closes: #497965)
  + Kurdish
  + Japanese (Closes: #494816)

Version 0.4.11.9                            "This message brought to you
                                             courtesy of the Friends of
					     Poland society."

- Bug fixes:

+ Minor bugs:

* Don't annoy every Polish user with a warning about a badly
      formed string in the aptitude-defaults configuration file.  Also
      added some documentation for translators telling them about the
      pitfall that led to this bug happening. (Closes: #483459)

* Fix some case fallthroughs that would cause the wrong
      information to appear in the "archive" (%t) column for virtual
      packages.

* Correctly handle install-and-mark-auto commands that are
      targeted at a particular version, like "install foo/testing+M".
      Previously aptitude would completely ignore the archive in this
      case.

- Translation fixes:

+ German
  + Slovak
  + Swedish (Closes: #490782, #490818)

[2008-07-04]
Version 0.4.11.8                            "Happy Fireworks Day."

- Bug fixes:

+ Minor bugs:

* Fix a long-standing and annoying bug that would cause aptitude
      to sometimes delete package lists if downloading new copies
      failed.  (Closes: #201842, #479620)

[2008-06-28]
Version 0.4.11.7                            "Yes I can"

- Internal changes:

* Fix several compilation errors on exotic architectures.
    (Closes: #488132)

- Translation updates:

* Basque
  * Portuguese (Closes: #482094)
  * Thai

[2008-06-21]
Version 0.4.11.6                            "Take two"

- Internal changes:

* Fixed several places where the code was a bit sloppy in ways that
    were harmless at the moment but were turned up by -Wall -Werror.

[2008-06-21]
Version 0.4.11.5                            "A tisket, a tasket"

- Bug fixes:

+ Crashes and serious errors:

* aptitude will no longer suggest removing Essential packages to
      fulfill dependencies unless you explicitly allow it to.  Also,
      removing apt (if it is allowed) will be scored as if apt were an
      Essential package, meaning that it should show up last in any
      list of solutions. (Closes: #486748)

+ Minor bugs:

* "aptitude add-user-tag" and "aptitude remove-user-tag" will
      return 0 instead of a random value when they succeed.

+ Translation updates:

* Dutch (Closes: #486858)
    * Romanian (Closes: #486934)

- Internal changes:

* Consistently build with -Wall -Werror (it wasn't being used in all
    subdirectories of the code).

* Clean up various minor and potential bugs turned up by increasing
    the warning level.

[2008-06-07]
Version 0.4.11.4                            "Turn down the suck."

- New features:

* "aptitude download" now properly handles both patterns and things
    like version specifiers that contain a tilde.

* New option "--disable-columns" to "search" that prevents aptitude
    from trying to reformat its output into columns.  This should be
    useful for people trying to call aptitude from scripts.
    (Closes: #136874)

- Crashes and serious errors:

* Fix a problem with assigning scores in the dependency resolver
    that severely distorted the relative weights of packages.  If a
    package conflicted with a virtual package that it also provided
    and replaced, aptitude would randomly score some of its versions
    as if they were full replacements of the current version.  This
    could lead to surprising and wrong resolver outputs.
    (Closes: #483920)

- Documentation bugs:

* Fix some broken internal links.

* The manpage formatting of <literal> elements is correct now.
    They're bolded, and literal file extensions don't get
    misinterpreted as groff escapes.  (Closes: #473580)

- Translation updates:

* Install defaults files for locales that contain an underscore,
    like pt_BR. (Closes: #483620)

* Russian. (Closes: #483943)

[2008-05-26]
Version 0.4.11.3                            "Not looking back."

- Crashes and serious errors:

* "unhold" should work now. (Closes: #477165)

* Fixed viewing changelogs at the command-line, which was almost
    totally broken in recent releases. (Closes: #481458)

* Fix getting the changelogs of bin-nmued packages from the curses
    interface. (Closes: #333468) For some reason when this was fixed
    for the command-line mode, the equivalent change didn't make it
    into the curses codebase.

* Don't die with an assertion error when --show-why is used in the
    presence of impure virtual packages.

- Cosmetic and UI bugs:

* Always be at least as quiet as the user requested; when aptitude
    automatically enabled quietness if its output wasn't a TTY, it
    could actually become less quiet than otherwise! (Closes: #476749)

* If the user asks for the justification of a manually installed
    package, try to find a nontrivial answer (some other package that
    requires it) instead of just telling them that it's already
    installed. (Closes: #477038)

* Remove an incorrect hyphen in the output of --help. (Closes: #476835)

* When the resolver is run several times in a row without user
    interaction (for instance, in "safe-upgrade"), only print
    "Resolving dependencies..." once.

* When listing the complete chains of dependencies that are holding
    a package on the system, show "A provided by B" as "A <-P B", not
    "AP<- B".  (i.e., add a space after "A")

- Build system fixes:

* VPATH should be supported better in doc/.

* Most files will generate Doxygen output now (they were missing
    \file tags).

- Documentation bugs:

* Clarify how aptitude's search language behaves in some syntactic
    corner cases, like "~nname?installed": the "?" is part of the
    string parameter to the first matcher, not the start of a new
    match term "?installed".

* Change the documentation of "aptitude why": it shows why packages
    should be installed, not why they can be installed, and be clearer
    about what happens when "why" is called with a single argument.

* Fix the manpage to talk about Recommends-Important instead of
    Install-Recommends. (Closes: #480533)

- Translation updates:

* Brazilian Portuguese (Closes: #481007)
  * Danish (Closes: #476732)
  * French
  * Galician (Closes: #476837)
  * German (Closes: #476344)
  * Japanese
  * Norwegian Bokmal (Closes: #480063)
  * Polish (Closes: #480062)
  * Simplified Chinese (Closes: #475740)
  * Vietnamese (Closes: #477295)

[2008-04-09]
Version 0.4.11.2                            "How far the sky,
                                             how cold the night,
                                             how still the flowing river.
                                             How sharp the air --
                                             so pure the light --
                                             beneath Orion's quiver.
                                             Beneath the frozen, staring,
                                             starry sky we lay a-shiver."

- New features:

* The information area can display tabs for the alternative views it
    supports.  This is off by default because I found that it was too
    intrusive (mainly because it appears between the short and the
    long description of a package).  If cwidget gets the ability to
    put tabs at the bottom of multiplex widgets, I might change this.

- Documentation bugs:

* Fix several XML errors in the manpage source (Closes: #473722)

- Bug fixes:

+ Crashes and serious errors:

* Make the safe resolver not explode exponentially when new
      Recommendations are present.

The root cause here was that the "mandate" mechanism the safe
      resolver uses to ensure that it progresses monotonically towards
      a solution doesn't work in the presence of Recommends, so the
      resolver ended up exploring the entire space of possible
      resolutions to packages' Recommendations.  (Closes: #474680)

* Don't crash if a package's Section is empty. (Closes: #474115)

+ Cosmetic and UI bugs:

* The "why installed" information display in the package list will
      now display an informative message when no package is selected,
      the same way that the "related dependencies" display does.

* The "why installed" information display should work better for
      newly installed packages now.

* "aptitude --version" prints more information about the libraries
      it was compiled against.

* "Help -> About" prints a correct copyright date now.

* The status indicator has been rewritten so that it no longer
      needs numeric conjugation (meaning it won't say "there are 1
      update").  (Closes: #486186 and friends)

* "why" and "why-not" now appear in the list of commands in
      "aptitude --help". (Closes: #454088)

+ Minor bugs:

* Use a 'latch' configuration option to migrate from
      Recommends-Important, instead of just clobbering the old
      option. (Closes: #473872)

* Treat packages that were removed but whose configuration files
      remain on the system as if they're not installed in the output
      of --show-why.

This fixes some cases where --show-why would hide the reasons
      for some installations.

Version 0.4.11.1                            "No, no, fool, I said bring
                                             me the FLUFFY Bunny
                                             Slippers of EXTREME

                                             around here?"

- New features:

* The command-line argument --show-why will cause all installation
    and removal commands to display a brief summary of the
    dependencies related to an installation or removal.  For instance:

The following NEW packages will be installed:
          libboost-iostreams1.34.1{a} (for wesnoth)  wesnoth
          wesnoth-data{a} (for wesnoth)  wesnoth-music{a} (for wesnoth)

Note that wesnoth-music is a dependency of wesnoth-data, not
    wesnoth.  --show-why displays the manually installed package
    behind each automatic installation.  If -v is passed on the
    command-line, it displays the entire chain of dependencies leading
    to each manual package.

--show-why also handles upgrades:

The following packages will be upgraded:
          klibc-utils  libklibc (for klibc-utils)

--show-why is limited to the capabilities of the logic behind
    "aptitude why".  Although libklibc might be the package that was
    originally marked for upgrade, --show-why has no knowledge of this
    fact: it just knows that klibc-utils requires libklibc.

* In the ncurses interface, added a menu entry to cycle the display
    in the lower pane (equivalent to pressing "i" but more
    discoverable).

* The ncurses interface now displays the number of packages in a
    tree next to the tree header, and in the information area when the
    header is highlighted.

* The header for the list of versions in the ncurses interface now
    reads "Versions of <package>" instead of just "Versions".

* A new extract-cache-subset command that will create a reduced copy
    of the package cache, removing all but a given list of packages
    and all references to packages not in the list.  It's intended
    for, e.g., generating test cases for package managers.

- Bug fixes:

+ Crashes and serious errors:

* Handle exceptions thrown by the Debtags constructor (e.g., when
      debtags has been purged and there are no data files) instead of
      just crashing.  (Closes: #472695)

* Eliminate a case where we would access uninitialized memory
      while starting up, found thanks to valgrind.

+ Cosmetic and UI bugs:

* Correct the documentation within the on-line help of how to
      leave the on-line help (it was never updated when the help went
      from being a dialog to being a top-level view).

* Correctly save changes to string configuration options.
      (Closes: #471315)

* Don't print an error on startup when debtags isn't
      installed. (Closes: #472678)

* Use less technical language when "why" fails to find a
      derivation for "A transitively requires B".

* Eliminated some cases where description signals for tree
      headings weren't being connected.  These weren't noticable in
      the past because in most cases, the heading had no description
      anyway.

- Translation updates:

* The aptitude-defaults.* files are now installed to
    /usr/share/aptitude. (Closes: #472625)

* Simplified Chinese (Closes: #458162, #473363).

* Vietnamese (Closes: #473229)

[2008-03-15]
Version 0.4.11                              "When you're tired of
                                             being beat with a stick,
               				     you're tired of Debian."

- New features:

* Search terms can be named with words instead of single-character
    flags.  Each new-style search expression starts with a question
    mark ("?"), followed by the name of the matcher; for instance,
    "?obsolete" is equivalent to the old-style expression "~o".  At
    the command-line, package names containing question marks are
    treated as search expressions, just like package names containing
    tildes ("~") are.

The old-style syntax is still present and works just like it did
    previously.  See the reference manual for complete documentation
    of the new syntax.

This will hopefully make the search syntax more memorable and make
    it clearer what a given search expression actually does.  In
    addition, this opens up the possibility of greatly expanding the
    number of search patterns supported by aptitude (the requirement
    to choose a meaningful and unique single character had become a
    major limiting factor in the ability to add new search terms).

* New search terms:

+ ?source-package(expr) matches packages whose source package matches
                            the given regular expression.
    + ?source-version(expr) matches packages whose source version matches
      			    the given regular expression.
    + ?all-versions(expr)   matches a package if expr matches all versions
                            of that package.
    + ?any-version(expr)    matches a package if expr matches any single
                            version of that package.
    + ?user-tag(pattern)    matches a package if it has an attached
                            user-tag matching the given regexp (see below).
    + ?for var: expr        binds var inside expr to the package or
                            version being tested.
    + ?bind(var, expr)      matches anything if the package or version
                            bound to var matches expr.
    + ?=var                 matches the package or version bound to
                            var by an enclosing ?for.

For instance, "?for x: ?depends(?recommends(?=x))" will match any
    package X that depends on a package that recommends X.

* aptitude now supports attaching arbitrary strings to packages,
    known as "user tags" (to distinguish them from debtags tags).  The
    following commands will manipulate user tags:

aptitude add-user-tag    tag package...
      aptitude remove-user-tag tag package...

Each of these commands will add user tags to or remove them from
    one or more packages (possibly selected using search expressions).
    In addition, all command-line actions that modify package state
    now take the following optional arguments:

--add-user-tag         TAG
      --add-user-tag-to      TAG PATTERN
      --remove-user-tag      TAG
      --remove-user-tag-from TAG PATTERN

The variants that take a PATTERN will add tags to or remove tags
    from any packages that match the given PATTERN. (e.g.:
    "--add-user-tag-to installed-for-build-dep ?action(install)").
    The variants that do not take a PATTERN will affect any package
    that is being modified (this is equivalent to using the pattern
    "?not(?action(keep))").

The ?user-tag(tag) matcher will select packages with a tag
    matching the given regular expression.  User tags also show up at
    the end of package descriptions, next to the list of debtags tags
    for a package.

* All command-line actions that modify package state now accept the
    arguments --safe-resolver and --full-resolver.  --safe-resolver
    forces the command to use the same resolver logic as
    --safe-upgrade (e.g., "aptitude install --safe-resolver exim4" to
    install exim4 as long as it can be installed without removing any
    packages).  --safe-resolver can be enabled in the config file by
    setting Aptitude::Always-Use-Safe-Resolver to "true"; passing
    --full-resolver will override this configuration option.

The option --no-new-installs and the new option --no-new-upgrades
    will control whether the safe resolver attempts to install new
    packages or upgrade installed packages.

Future versions of aptitude will enable this logic in the curses
    UI as well, but I haven't decided how it should be exposed yet.

* The aptitude dependency resolver will now refuse to adjust held
    packages or install forbidden versions unless you manually allow
    it to.  This behavior can be disabled by setting
    Aptitude::ProblemResolver::Allow-Break-Holds to "false".

aptitude will still break holds when packages are being
    automatically installed; there is a pending patch against apt that
    eliminates this behavior.

* The aptitude dependency resolver will add a bonus to solutions
    that remove a package and install another package that fully
    replaces it by declaring a conflicts/provides/replaces
    relationship. (Closes: #466374)

* aptitude now has a "build-dep" command that will install
    build-dependencies from the command-line. (Closes: #243317)

* A new "subdirs" variant of the section grouping policy is
    introduced in this release, courtesy of Paul Donahue, and is
    enabled by default.  This will behave just like the old sectioning
    policy, except that if a section has several components (for
    instance, games/arcade/space), they will all be realized as tree
    levels in aptitude.

A side effect of this change is that section descriptions are no
    longer hard-coded in the source (see the documentation of
    Aptitude::Sections::Descriptions).

* Command-line updates in aptitude will now list packages that are
    newly obsolete.  This doesn't work when a source is removed and
    all its packages become obsolete, for technical reasons.

* aptitude now uses libept to handle debtags information instead of
    a slow and wrong internal implementation. (Closes: #397652,
    #406201) "aptitude update" will merge new package information into
    the debtags database automatically by running "debtags update --local".

- Bug fixes:

+ Cosmetic and UI bugs:

* The curses interface now uses a spinner to indicate download
      progress, since the percentage measurement can't be made correct
      in the current apt model.

* Remove some stray cw:: strings that made it into user-visible
      messages (thanks to Jacobo Tarrio for pointing them out).

* Interpret %-escapes in the descriptions of configuration options
      instead of displaying them to the user; thanks to Jens Seidel
      for pointing this out.

* At the command-line prompt, don't list packages that aren't
      being upgraded unless the user tried to upgrade them.  e.g.,
      "aptitude install foo" will no longer spew the entire list of
      pending upgrades to the terminal.

* When displaying dependencies or version numbers at the
      command-line (i.e., -D or -V is passed), add an extra space
      between packages, to make it a little more obvious which tags
      "belong" to which package.

* If the resolver is allowed to produce the solution 'cancel all
      actions' (i.e., "Aptitude::ProblemResolver::Discard-Null-Solution"
      is false), the brief indicator in the UI will say that it cancels
      all the pending actions instead of counting its component actions.

* When displaying the packages that could satisfy a versioned
      dependency, don't list packages that provide the package name
      unless they declare a versioned provides that matches the
      dependency's version restriction. (Closes: #464131)

* Don't try to generate and then parse a matcher when searching
      for packages that look like what the user typed; instead, write
      explicit code to compare against package names and descriptions.

This allows aptitude to find similar package names even if the
      corresponding command-line argument is an invalid search pattern
      (without having to write complex escaping logic); e.g.,
      "aptitude install +5" does something sensible instead of
      printing a confusing error message.

* If the user enters "q" during command-line dependency
      resolution, quit the program instead of falling back to manual
      resolution; manual resolution is only used if automatic
      resolution hits a fatal error or if the user requests it by
      typing "x". (Closes: #459629)

+ Translation bugs:

* Generate POTFILES.in automatically, so it stays up-to-date
      without requiring manual intervention.

* Flag W_() as a translation marker; failure to do this caused a
      lot of strings to be incorrectly left out of the translation
      files; pointed out by Jens Seidel.

* Fix translation of strings displayed by the options editor (they
      weren't getting translated at all); thanks to Jens Seidel for
      reporting this.

+ Minor bugs:

* Fix task handling in the case that different versions of a
      package are in different tasks. (Closes: #459348)

* "safe-upgrade" will now attempt to automatically maximize the
      upgrade.  Hopefully this will eliminate the situation where you
      run "aptitude safe-upgrade" and then discover that there are
      still some upgradable packages.

+ Crashes and serious errors:

* aptitude will now build with g++ 4.3, assuming that
      4.3-compatible versions of cwidget and sigc++ are installed.
      (Closes: #452204, #452540)

* Reduce the translation percent threshold for the various
      versions of the manual until it compiles. (Closes: #470054)

* aptitude now uses Apt::Install-Recommends instead of
      Aptitude::Recommends-Important to control whether
      recommendations are automatically installed.  (Closes: #458189,
      #448561) Old configurations will be migrated to the new
      configuration option, if possible.

Among other things, this means that --without-recommends works
      again (it was broken when recommends handling moved to apt).

* Ensure the resolver state is always synchronized with the
      package cache, eliminating some cases where the resolver would
      break or produce wrong answers. (Closes: #421395, #432411)

* Don't crash at the command-line when displaying the version
      numbers of packages being removed that don't have an
      installation candidate; also, the version display for removed
      packages is now meaningful. (Closes: #459336)

* Don't crash at the command-line when displaying the version
      numbers of packages in the ConfigFiles state that are being
      purged; instead, display "Config Files" as the removed
      version. (Closes: #461669)

As a side note: the code in question has been adjusted to be
      robust against bad version pointers, and should display "??"
      instead.  If you see this, it's a bug, but at least aptitude
      won't crash in this case.

* Don't crash in "aptitude update" when the package lists can't be
      parsed for some reason; instead just go ahead and download new
      ones. (Closes: #468751)

+ Documentation bugs:

* Fix the documented default keybinding for PrevPage.

* The documentation of searching has been substantially rewritten,
      and is hopefully much more useful now.  In particular, there's
      more information about how versions are handled, and a concise
      table listing all the search expressions supported by aptitude.

* Document some of the files aptitude uses in a FILES section in
      the manpage (Closes: #470839).

+ Translation updates:

* Basque

* French

- Christian Perrier: Fix the use of quote in the French
         translation (Closes: #460808).

* Galician

* German (thanks to Jens Seidel)

[2007-12-15]
Version 0.4.10                              "Oscillating Reindeer"

- New features:

* In command-line mode, if the resolver fails to produce a solution
    for whatever reason, then instead of aborting the program entirely
    aptitude will now display a prompt at which you can fix the
    dependency problems by hand.  Enter "r" at this prompt to try to
    automatically fix dependencies again.

* safe-upgrade will now install new packages to fulfill dependences
    (but it will never remove packages, downgrade packages, or install
    a version that's not the default).  The option --no-new-installs
    will disable this behavior.

* Updates and commands that install, remove, or upgrade packages
    will now display a brief summary of what changed.  For instance:

There are now 64 updates [+10], 3 new [+1].

Unfortunately, this change requires reading the cache after an
    update is complete.  Passing -q will disable this behavior, but
    also make the update progress bar less attractive.  More work on
    resolving this tension between features and performance remains to
    be done.

* Add an option --allow-untrusted to override trust warnings.
    (Closes: #452201, #452541)

* Recommended packages are now hidden if quiet mode is enabled.
    (Closes: #452202)

* The options Aptitude::ProblemResolver::Trace-File and
    Aptitude::ProblemResolver::Trace-Directory allow you to generate a
    minimal cut of the cache that allows a problem resolver run to be
    reproduced.  The eventual aim is both to simplify bug reporting
    and to generate a corpus of automatic test cases for the resolver
    (although more work needs to be done to accomplish the latter).

* When run in command-line mode, instead of displaying many separate
    and sometimes duplicative groups of packages (e.g.: installed,
    auto-installed, auto-installed in a light cream sauce, etc),
    aptitude displays packages in a few exclusive categories and uses
    tags (like the existing "purge" tag) to provide more state
    information.  For instance:

$ aptitude -s install wesnoth
      The following NEW packages will be installed:
        wesnoth wesnoth-data{a} wesnoth-music{a}
      $ aptitude -s remove freeciv-data
          (... dependency resolution ...)
      The following packages will be REMOVED:
        freeciv-client-gtk{a} freeciv-data freeciv-server{a} ggzcore-bin{u}
        libggz-gtk1{u} libggz2{u} libggzcore9{u} libggzdmod6{u} libggzmod4{u}

Here {a} indicates that a package was automatically installed or
    removed, and {u} indicates that a package is being removed because
    it is unused.  Hopefully this will be less confusing than the old
    format.

- Bug fixes:

+ Crashes and serious errors:

* Track down and fix a SEGV triggered on the first action after a
      cache reload (sometimes).  There are multiple bugs where this
      might have been the root cause, but it's confirmed that it was
      the cause of at least #454695, #454700, #455349, and #453362.
      Bug #455865 is almost certainly the same issue, and bug #352278
      may be another manifestation of it.

* If StepLimit is set to 0, refuse to solve dependencies instead
      of going into an infinite loop.  (Closes: #451311)

+ Minor bugs:

* Return a failing exit code after jumping from the command-line
      to visual mode if the last install run failed. (Closes: #282408)

* Return a failing exit code from "aptitude update" if any
      download fails. (Closes: #233129)

+ Cosmetic and UI bugs:

* In addition to Enter, Space will now activate checkboxes and
      radio buttons. (Closes: #451765)

* Abort the program if we get EOF at the resolver prompt instead
      of claiming the resolver failed.

* Command-line searches will now only print each result once.
      (Closes: #450798)

+ Documentation bugs:

* The options menu documentation now minimally describes the new
      configuration interface.

* The documentation of the configuration file options has been
      placed back in alphabetic order after apparently suffering
      bitrot over the years.

* Corrected the documented default of Parse-Description-Bullets to
      match reality.

* The manpages for aptitude-create-state-bundle and
      aptitude-run-state-bundle are now generated using DocBook, which
      should produce higher-quality and more consistent typesetting,
      as well as making the manpages more maintainable and allowing
      translators to easily produce localized versions of the manpages.

- Internal changes:

* Removed some unit tests that really tested cwidget.

- Translation updates:

* French (Christian Perrier)

[2007-11-17]
Version 0.4.9                               "Ow. Ow. Ow. Ow. Ow."

- New features:

* Add a matcher ~o for obsolete/local packages. (Closes: #397547)

- Bug fixes:

* Correctly set the name, description, and long description
    of radio options. (Closes: #449138)

* Don't remove *.gmo in distclean.  Apparently this causes trouble
    for translations. (Closes: #451584, #441696)

[2007-11-15]
Version 0.4.8                               "The fun never stops!"

This change removes the internal widget set, instead using the cwidget
curses widget library (which just happens to provide all the same
functionality as the aptitude widget set, imagine that).

- Bug fixes:

+ Cosmetic and UI bugs:

* Interpret key names in the broken indicator as wide-character
      strings; fixes actual display corruption on some platforms and
      potential corruption on all platforms.  (Closes: #448753)

[2007-10-30]
Version 0.4.7                               "Where did all these
                                             balloons come from?
                                             And why am I wearing
                                             a fake nose?"

- New features:

* The options dialogs have been completely replaced by a new
    interface, based on a top-level list view.  This fixes many
    deficiencies of the old interface: it handles long strings more
    gracefully, avoids many of the focus-handling bugs that the old
    dialogs had, and should generally be better-behaved.
     (Closes: #197976, #331200, #424708)

* Prompts that ask you to enter text will now wrap to multiple lines
    when the text gets long, rather than hiding parts of the string.

* The online help and other Help-menu items are now top-level views,
    which should make them somewhat more usable. (Closes: #434349)

* Support for the "Breaks" field and for trigger states (thanks to
    Michael Vogt and Ian Jackson for patches and prodding).
    (Closes: #438548)

* Two new styles, "PkgDowngraded" and "PkgDowngradedHighlighted",
    are provided to control how downgraded packages look.  By default
    these packages look like any other installed package.
    (Closes: #439924)

* aptitude can now display homepage URLs stored in the Homepage
    field of packages.  This requires a recent version of apt;
    0.7.8 or better includes it.

- Bug fixes:

+ Crashes and serious errors:

* When applying the resolver's output, only set the packages that
      are newly installed to be automatic, rather than making
      everything the resolver touches automatic.

* Save and restore the automatic flag on packages that are not
      not currently installed and that are being installed.
        (Closes: #435079)

* Fix the help generated when the user presses '?' at the prompt
      to not segfault, and rewrite the code to avoid this bug in the
      future (it was using a format string with a huge number of
      placeholders; now it builds a list of the output lines
      explicitly).

* Eliminate a crash on startup caused by using a global pointer to
      the cache in the package matching logic (which might be null)
      instead of taking a valid pointer to the cache as a parameter.
      This is necessary since the matcher might be invoked while the
      cache is being loaded, e.g., to decide if a package should be
      part of the root set.

+ Minor bugs:

* Fix the 'pattern' grouping policy: it was inserting packages
      into all the trees that matched, not just the first one.

* Make removals and holds that occur later on the command-line
      override earlier commands.

* The debugging output from "why" no longer tries to dereference
      invalid pointers or display multibyte strings as single-byte
      strings. (Closes: #447290)

+ Cosmetic and UI bugs:

* If the text in a column of the "why" output exceeds the column
      width, the column will now wrap correctly onto the next line.

* Auto-held and unconfigured packages no longer generate ?????? in
      the aptitude log.

+ Documentation bugs:

* Fix the documentation on aptitude development.  It now gives the
      correct URL and version control system for the upstream
      repository, and somewhat more actively solicits contributions.

Version 0.4.6.1

- Minor bugfix to include the new scripts/manpages that didn't get
  distributed with the previous release.

[2007-07-25]
Version 0.4.6                               "He who works and works
                                             all day, gets to work
                                             another day."

- New features:

* Added two programs, aptitude-create-state-bundle(1) and
    aptitude-run-state-bundle(1), to eliminate some of the drudgery
    involved in collecting apt state and running aptitude with a state
    snapshot.

* "why" output is now available in visual mode (hit 'i' to cycle
    through informational displays).  The formatting and styling are
    pretty awful in this release.

- Bug fixes:

+ Crashes and serious errors:

* Handle EINTR from select() better; thanks to Jiří Paleček for
      tracking this down. (Closes: #431054, #431688, #432323)

Note that there is still a race condition lurking here, although
      it's almost impossible to trigger it.  The next release should
      eliminate it, though.

* Run mark-and-sweep on startup, to initialize apt's auto flags.
      This should prevent aptitude from losing the auto flag when a
      package is marked for upgrade. (Closes: #432017)

* Don't crash on startup when something goes wrong early in the
      initialization process (e.g., when the cache is locked;
      Closes: #430061).

+ Minor bugs:

* Disable unused-package removal if Delete-Unused is false.
      (Closes: #431716)

+ Cosmetic and UI bugs:

* Don't garble descriptions in non-UTF8 locales. (Closes: #432911)

* Hopefully fixed the problem that was garbling the startup
      progress indicator.

* Eliminate another bogus error about a supposedly locked cache.
      (Closes: #431909)

+ Documentation bugs:

* Fix the manpage's metainformation so that the footer gets
      generated.

+ Potential bugs:

* Handle some unusual cases where the resolver could dereference
      invalid pointers (no bugs reported).

* Added code to recover with an error if apt improperly marks a
      dependency as broken.

Version 0.4.5.4                             "Oh my God,

                                              but I wanted to say that)"

- New features:

* Expose the "why" command from the command-line Y/n prompt.  Typing
    "w <args>" will invoke "why <args>".  The resolver prompt doesn't
    support this, maybe it should?

- Bug fixes:

+ Crashes and serious errors:

* Eliminate a bounds error that was crashing the vs_editline.
      (Closes: #429673)

+ Minor bugs:

* Force aptitude to write out a state cache the first time it
      runs.  Without this change, it won't know which packages are
      "new" until after the first time the user installs something.
      (Closes: #429732)

+ Build system fixes:

* Add a configure check for the new apt, so users get more
      sensible build errors with incompatible apts.

* Have 'make clean' remove autogenerated XML files, so they don't
      show up in the Debian diff.

                                             Of The Code"

- New features:

* Added two commands "aptitude why" and "aptitude why-not" that
    provide explanations of why a package is, must be, should be, or
    must not be installed on your system.  They are not complete, by
    which I mean that they can't always provide the most useful
    justification, but they should answer a lot of questions that I
    hear people asking regularly.

- Bug fixes:

+ Crashes and serious errors:

* Eliminate a nasty race that was probably the cause of corrupted
      output on some dual-core systems. (Closes: #414838, #406193)

* Fix a bug that could cause aptitude to try to remove a package
      that it had already removed. (Closes: #429388) This can't be
      totally eliminated without help from dpkg, but hopefully this
      fix will make the problem much more difficult to trigger.

Unfortunately, the fix also means that aptitude has to perform a
      save/load cycle after installing packages to make sure that
      everything is consistent.

* Allow "keep" actions to be undone.

* Don't consider every removed package to be an unused package.

* Clear the broken package indicator when the user undoes an
      action.

* Fix build errors on other architectures. (Closes: #429348)

* Set packages to manual mode when the user cancels their removal.
      (Closes: #429271)

* Fix compile bugs with g++-4.3. (Closes: #413488)

                                             to meow feline"

- Bug fixes:

* Multiple minor bugs introduced by the patches to support apt's
    auto-marking were fixed.
    - Packages kept at their current version by applying a solution
      no longer get their hold flags turned on.
    - Packages that are installed by a solution get their auto-installed
      flag set.
    - Applying a solution updates the resolver state (so the error
      bar doesn't stick around until you change a package's state
      by hand).

* Fixed a broken cross-reference in the manpage.

[2007-06-15]
Version 0.4.5.1                             "Nothing could possibly go
                                             wrAAAAAAAAAAaaaa..."

- New features:

* aptitude now uses apt's central database to track which packages
    are auto-installed.  Aptitude's own list of automatic packages
    will be merged into the global list the first time that aptitude
    is run.

* Packages that are not fully configured are now listed in aptitude's
    preview, and aptitude will let you do an install run if there are
    unconfigured packages but nothing to install/remove. (Closes: #424709)

[2007-05-14]
Version 0.4.5                               "Confused Cockroach"

- New features:

* For standard string prompts, the default is now initially
    displayed, but erased if the user starts out by inserting a new
    character.

* 'N' now repeats the last search in the opposite direction (as
    opposed to 'n', which repeats it in the same direction).
    (Closes: #414020, #397880)

* aptitude now recognizes Apt::Get::AllowUnauthenticated as a
    synonym for Aptitude::Ignore-Trust-Violations. (Closes: #411927)

* Fix the handling of dselect/dpkg state.  Previously, mixing the
    command-line and visual modes of operation could result in
    aptitude thinking it should remove a package that was actually
    installed on your system.  This was especially nasty since the
    Debian installer tripped this condition, leaving people with a
    broken initial system.  Ow.  (Closes: #411123)

* Added a config option "Aptitude::CmdLine::Resolver-Show-Steps",
    which causes the dependency resolver to default to displaying its
    output as a list of individual resolutions, rather than a list
    organized by the type of change that will be made. (equivalent to
    pressing "o" at the first resolver prompt)

* Added "safe-upgrade" and "full-upgrade" as synonyms for "upgrade"
    and "dist-upgrade" respectively.  The goal here is to eliminate
    massive confusion about what these commands actually do.
    "upgrade", in particular, is now deprecated ("dist-upgrade"
    probably has too much currency to kill off, but hopefully people
    will at least be rid of the notion that it's exclusively for
    whole-distribution upgrades).

* The option "Aptitude::Get-Root-Command" can be used to choose how
    aptitude tries to gain root privileges.  It defaults to "su";
    setting it to "sudo" will choose that program, and other programs
    can also be chosen (see the user's manual for details).

- Bug fixes:

+ Crashes and serious errors:

* Improve the internal consistency of aptitude's reduction of the
      apt dependency graph.  As part of this change, a new
      (undocumented, primarily for debug purposes) command-line action
      "check-resolver" was added; it verifies empirically that the
      dependency structure obeys the invariants that it's expected to
      obey (for instance, that all forward dependencies have a
      corresponding reverse dependency).

In addition to a number of harmless discrepancies, this flushed
      out the forward/reverse dependency mismatch that was causing
      crashes in the resolver. (Closes: #420358, #420381, #420407).

Note that check-resolver only verifies *internal* properties of
      the resolver's model; it doesn't verify that the model
      faithfully represents the dependency problem posed by the apt
      package database.

* Don't crash on amd64 and other architectures where va_args
      structures can't be reused.  This is an old bug; it was turned
      up by a new test for ssprintf.

* Increase the default value of StepScore to 70 and improve its
      documentation.  This should make it much less likely that the
      resolver wanders off into lala land trying to solve dependency
      problems. (Closes: #418385)

* When --without-recommends is passed at the command-line,
      automatically enable Keep-Recommends at the same time we disable
      Recommends-Important, so we don't automatically remove half the
      user's system. (Closes: #143532)

* Fix an internal sprintf variant to produce correct output (the
      previous code was safe, just wrong; it safely produced a buffer
      of the correct size, then truncated it to its initial buffer
      size).

* If the dependency resolver throws an exception, catch it and
      handle it as cleanly as possible, rather than unceremoniously
      exploding.

* Don't block signals when running dpkg after a package install
      failed, and tell dpkg not to use TSTP in this circumstance.
      This tended to cause horrible breakage of dpkg's
      auto-backgrounding (the "Z" conffile prompt option).
      (Closes: #367052)

* Fix a crash that occurred when generating a revdep-count column
      for some virtual packages. (Closes: #420405)

* Don't abort() if something tries to display a progress
      percentage that's not strictly between 0 and 100. (Closes: #425145)

+ Cosmetic and UI bugs:

* If a package is both "new" and "upgradable", place it in the
      "upgradable packages" list instead of the "new packages list",
      since this seems to be the path of least confusion. (Closes:
      #419999)

* Try to include more information when an internal consistency
      check is triggered (e.g., the dependency that the program was
      looking at).

* Only print an error about being unable to acquire a lock after
      downloading when an error actually occurred during the call to
      GetLock(); this message was getting triggered by stray errors
      from methods invoked earlier in the download/install
      process. (Closes: #422700)

* Don't ever display more than one "really quit?" dialog box, so
      people who hold down the "q" key don't have to also hold down
      "n". (Closes: #411158)

* When writing out the aptitude state file, open it mode 0644 and
      explicitly chmod it to mode 0644, so it doesn't start out
      world-writable, but ends up group- and world-readable even if
      root has a more restrictive imask.  pkgstates isn't
      security-sensitive, and aptitude produces surprising results if
      it can't read this file.  If you really need to hide pkgstates
      from non-root users for some reason, you can chmod -x the
      directory /var/lib/aptitude.

(Closes: #41809, #421811)

* If a command (e.g., update) takes no arguments, aptitude will
      produce an error if it receives arguments. (Closes: #411152)

* Write "[Enter]" instead of "enter" in the media-change prompt,
      to make it clear that the user should press the key of that
      name. (Closes: #414777)

* Remove *.gmo in distclean, so the Debian package can be built
      twice in a row. (Closes: #424102)

+ Potential bugs:

* Delete some internal cache arrays using operator delete[]
      instead of operator delete.

* Initialize package selection states to the Unknown state
      explicitly.

+ Documentation:

* Fix the docbook encoding of the users manual and manpages.

* Fix an error in the DocBook code of the manual page that caused
      the AUTHOR section to appear twice.

* Fix how bolding is applied to literal elements in the manpage,
      so that the manpages are no longer screwed up.
         (Closes: #415468, #416232)

* Users manual corrections (thanks to Noritada Kobayashi for
      patches).

* Improve the description of the Recommends-Important,
      Keep-Recommends, and Keep-Suggests: clean up the language and
      try to make their precise behavior clearer.  Thanks to Stefan
      Kangas for the initial suggestion. (Closes: #405002)

* Try to make it clearer in both the manpage and the user's manual
      that "aptitude search" does an implicit OR on its command-line
      parameters, rather than an implicit AND. (arguably it SHOULD do
      an "AND", but it's probably too late to change this now)

* Add some commands to the online help that weren't previously
      documented. (Closes: #402360)

* Fix misaligned items in the online help. (Closes: #399048)

[2006-10-26]
Version 0.4.4                           "I shall smite you with my
                                         Ultimate Power of Cuteness!"
- New features:

* "unhold" now just clears the hold flag; it doesn't try to upgrade
    the package that was just unheld.

* The grammar used to parse bulleted lists has changed.  Full stops
    are no longer considered to be paragraph breaks or otherwise
    significant unless they are indented by exactly one space (i.e.,
    unless they are significant in the standard grammar).

A second change introduced by this patch is that a full stop by
    itself on a line no longer terminates a bullet list; the list will
    continue as long as the text after the paragraph break is indented
    at the same level as the rest of the list.

This fixes some cases where aptitude badly mangled descriptions
    that used to work, and means I feel safe re-enabling bullets by
    default. (Closes: #388594)

- Bug fixes:

* By default, don't remove Linux kernel images that are unused.
    (Closes: #386307)

* Generate a more useful error message for corrupted or unverifiable
    file downloads. (Closes: #387537)

* Fix minibuffer messages so that they go away when you press a
    key. (Closes: #395201)

* Apparently time is allowed to go backwards, so don't assert that
    it doesn't in the test suite. (Closes: #381481)

* Document what "unhold" does. (Closes: #387336)

* Consistently use <literal> instead of <option> to mark up
    command-line options. (Closes: #388502)

* Force the package selected by a search to be at the top of the
    screen, so that it's visible underneath the search dialog.
    (Closes: #389763)

* Change the progress indicator to be less visually distracting:
    instead of flashing yellow and blue, just display the operation
    name and the current progress. (Closes: #390971)

* Unblock all signals before running dpkg, and restore the signal
    mask afterwards.  This should probably be done in libapt, but it
    isn't. (Closes: #392870)

* When abbreviating dependency types in the command-line preview
    (e.g., "Depends" or "Recommends"), use the first *character*, not
    the first *byte*; this fixes the preview in multibyte
    locales. (Closes: #395007)

* Fix iteration over a package's reverse dependencies when it has
    only indirect dependencies (dependencies through a virtual
    package).  Among other things, this means that packages which were
    getting left out of the list of "suggested/recommended packages
    not being installed" will show up correctly.

* When "aptitude show" is given a pattern as its argument, show all
    packages that match the argument, not just the "first" one.
    Thanks to Martin Dorey for this patch.

* Delay auto-resolving dependencies when installing packages from
    the command line, so that unnecessary stuff doesn't get installed
    when packages listed later are non-default alternatives of a
    dependency of an earlier package.

* Correct the default value of Request-Strictness to match the value
    that it was set to in 0.4.3.

* Fix the manpage's reference to the HTML documentation to point to
    the right location.

* Shorten the manpage's title so that it fits into the fixed-width
    field that "man" uses.

* Fixes for a bunch of documentation typos from Kobayashi Noritada
    (Closes: #389942).

* Close a very minor memory leak in "aptitude show".

[2006-09-03]
Version 0.4.3                           "Everyone loves kittens"
- New features:

* Request-Strictness is now set to 10000 by default.  This should
    cause the internal problem resolver to produce more sensible
    solutions when run from the command-line. (Closes: #385453)

- Bug fixes:

* Don't crash when trying to display text in the internal pager in
    which a tab character appears in a column that is not a multiple
    of 8. (Closes: #383488, #383549)

* Don't crash after su-ing to root. (Closes: #382090)

* Don't crash when saving the state while a non-default version of a
    package that has no default version at all (e.g., exists only in
    experimental) is selected for installation. (Closes: #383767, #384136)

* Eliminate duplicate entries from the "provided by" list displayed
    by "aptitude show". (Closes: #384001)

* Grotesquely hack around ugly behavior in 256-color terms by
    limiting the maximum number of foreground/background colors to 8.
    (Closes: #384699)

* Fix the incorrect claim in the documentation that "l" is the
    shortcut to remove the limit from the display.

* Make the in-menu hotkey for "mark upgradable" not conflict with
    "update package list".

* Use groff escapes for extended characters when generating manpages
    so that they look better in non-English locales. (Closes: #383463)

* Use the built-in Docbook XSLT templates to italicise <replacable>
    tags in manpages.  This is asserted to produce more correct
    output.

[2006-07-31]
Version 0.4.2                           "Rock on, Monkeyverse"
- New features:

* Added a command to cancel all pending actions from the full-screen
    UI (an analogue of "keep-all" at the command line).

* Added an option "Aptitude::UI::ViewTabs" that controls whether the
    "tabs" at the top of the screen are displayed. (Closes: #344569)

* Make the lockfile default to /var/lock/aptitude as per
    FHS. (Closes: #160418)

* Add support for searching in the on-line user's manual.
    (Closes: #364306)

- Bug fixes:

* Fix compilation errors with gcc 4.1. (Closes: #357557)

* Fix compilation errors with gcc 4.2. (Closes: #369382)

* Fix crashes that occurred during update (and perhaps install)
    operations if a problem resolver was active.
    (Closes: #346380, #348541, #348481, #376573)

* Don't crash when trying to install packages off multiple
    CDs. (Closes: #349869)

* Handle NULLs being returned from get_changelog_from_source
    (Closes: #343488).

* Don't crash when moving the selection up if the current selection
    is invalid (Closes: #343676).

* Disable bullet-detection by default, since it is
    backwards-incompatible in a bad way that cannot be easily solved.
    (Closes: #373888)

* Make bullet-detection better defined by requiring exactly one
    space after the bullet (subsequent spaces cause lines to be
    literally formatted; without this, literal lines in bulleted
    paragraphs aren't possible).

* Make the behavior of "aptitude show" more intuitive: state
    information corresponds to the Version displayed, and the current
    version is selected by default if the package is
    currently installed. (Closes: #375393, #372796)

* Use PTHREAD_MUTEX_RECURSIVE instead of PTHREAD_MUTEX_RECURSIVE_NP
    so we compile on the Hurd (Closes: #361439).

* Fix saving/restoring states when a non-default version is being
    freshly installed.

* Correct how the progress indicator is updated when rebuilding the
    cache.

* Don't read the package lists on startup when they're about to be
    discarded to download new ones. (Closes: #366884)

* Fix incorrect behavior in the command-line changelog routine,
    triggered by pending errors that weren't being dumped.
    (Closes: #379903)

* Fix several places where error reporting via Errno was broken.
    (Closes: #350264)

* Correctly handle scrollbar updates after resizing text layouts.
    (Closes: #347445)

* Fix how the internal pager renders tabs. (Closes: #351323)

* Remove the pkgAcqFileSane class; the functionality it provides is
    now available in libapt -- and better implemented, so this
    (Closes: #299127).

* Use correct xml in the manual.

* Add a (non-default) target to build printable documentation.

* Use UTF-8 to output the manpage.

- Translation updates:

* Add some plural form support.

* Fix the P_() localization macro.

[2005-12-08]
Version 0.4.1                           "Divers Alarums"
- New features:

* Assertion failures should print the failing assertion after
    shutting down curses rather than before.

* The --purge-unused option is now provided as a synonym for
    -o Aptitude::Purge-Unused=true.

* aptitude will now support ddtp if it is compiled against a version
    of apt that supports ddtp.

* Setting the Aptitude::Cmdline::Resolver-Dump option to a filename
    will cause the command-line mode of the program to dump a snapshot
    of the resolver state to that file before attempting to resolve
    dependencies.

* Setting the Aptitude::GC-Debug option will cause the garbage
    collector to print voluminous debugging information as it searches
    for unused packages.

- Bug fixes:

* Eliminate two deadlocks caused by the background resolver thread
    trying to wait for itself. (Closes: #340067, #342319)

* Never select a version that was removed but not purged and is no
    longer available as a candidate version. (Closes: #340385)

* Eliminate a corner case where the resolver could produce solutions
    that were supersets of previous solutions.

* If an EOF is encountered while waiting for a media-change from the
    command-line, signal media change failure instead of aborting.

* Don't ever use the minibuffer to display the list of packages
    adjusted by the resolver (Closes: #341292).

* If the menu bar is auto-hidden, don't automatically unhide it when
    the user clicks in the first row of the display; instead, pass the
    clicks to the sub-widget. (Closes: #341475)

* Enable colors on terminals where COLOR_PAIRS < COLORS*COLORS but
    COLOR_PAIRS >= 64.

* Honor -y when the resolver runs out of time at the command-line.

* Make "cancel" at the "download complete" dialog actually cancel.

* Fix a portability bug due to cross-platform variation in the
    members of sigaction (Closes: #337536)

* Fix how keybindings are parsed: keybinding names are now
    case-insensitive and single-character keybindings are parsed
    correctly. (Closes: #339131)

* Add spaces after various minibuffer prompts.

* Add a link from the search patterns documentation to the
    command-line reference.

* When saving the package states, properly handle the case in which
    the state file didn't previously exist. (Closes: #337869)

* Don't segfault when the user updates the package lists while a
    solution examiner is open. (Closes: #338441)

* Trust any package version for which at least one source is trusted
    (Closes: #337982).

* Work around apt bug #339533 to avoid an aptitude
    segfault. (Closes: #339648)

* Fixed the assertion failure message printed when an inconsistency
    is detected because a supposedly broken dependency isn't broken (it was incorrect).

* If a --schedule-only operation fails, print any errors that
    occurred before exiting.

* Document the new backslash behavior in help.txt. (Closes: #337810)

* Document that "default" can be used as a background color.

* Correct the names of the problem-resolver control knobs in the
    documentation.

[2005-11-04]
Version 0.4.0                           "Aptitude Below Zero"

- New features:

* The primary binding of the menu toggle command is now Control-t
    instead of f10.  All old bindings still work, but this means that
    the binding displayed at the top of the screen will work on all
    terminals. (Closes: #147862, #335034)

* By default, the solution that reverts all user actions is
    discarded entirely.

* The "changelog", "download", and "show" command-line actions
    recognize "-t <archive>" and handle it by acting as if
    "/<archive>" had been appended to each argument of the
    command. (Closes: #334096)

* When "show" cannot locate a package by name, it now exits with an
    error instead of exiting with status 0.

* When the user requests a particular version of a package, "show"
    will display only that version, even if the verbosity level would
    normally cause all versions to be displayed.

* Highlight stuff that looks like bullets when viewing a changelog
    file.

* Doxyfile.in is distributed, so the doxygen documentation should be
    buildable from the distributed tarball.

* Added a Keep-Recommends option that is analogous to Keep-Suggests:
    it doesn't cause recommendations to be automatically installed,
    but it does cause them to be held on the system by the garbage
    collector if they were automatically installed.

- Bug fixes:

* Forward and reverse dependency lists are sorted by name and
    version.

* Made page-up in a list of packages properly trigger the update of
    all connected information.

* "search" now completely ignores fake packages (Closes: #337407).

* The code to parse a bullet list in a description now knows how to
    handle any number of spaces following a bullet (including
    zero). (Closes: #337344)

* Don't hide the preview screen when downloading stuff other than
    packages. (Closes: #334343)

* Deal sanely with changelogs and other formatted text that
    contains newlines or tabs.

* More real and potential UTF-8 display problems fixed.
    (Closes: #317119)

* Fix some anomalies in the display of the menu bar's left/right
    arrows.

* Corrected how the sigc++ version against which the program was
    compiled is reported.

* Added "install" to the manpage synopsis. (Closes: #336584)

* Cleaned up some parts of the resolver interface and wrote
    top-level API documentation for it.

Version 0.3.5.1                         "Slantwise Cacophany"

- Bug fixes:

* Corrected several trivial but fatal bugs in the build and install
    system.

* Document 'aptitude reinstall' in the --help output. (Closes: #333872)

- Translation updates:

* Add a Swedish translation of help.txt. (Closes: #333918)

[2005-10-13]
Version 0.3.5                           "Yoink"

Upstream aptitude development is now stored in darcs.  See the
   documentation for additional details.

- New features:

* Redesigned how versions are handled in the pattern matching
    language.  The set of versions matched against is more uniform
    (typically all the versions of a package).  This set is narrowed
    at appropriate times; for instance, reverse dependency matchers
    will only pass those versions that assert a dependency into their
    subexpression.  You can manually narrow the set by selecting
    versions with ~S, and manually widen it by using ~W.

* Forward and reverse dependency matchers can be restricted to only
    broken dependencies.

* The version matcher (~V) has support for matching the current,
    target, or candidate version of a package (in addition to matching
    a regexp against the version number).

* Add a canned package view that only displays packages which are
    targets of unsatisfied Recommends.

* Sort reverse and forward dependencies by package name and version
    number.

* In the command-line preview, display {p} next to packages that are
    being purged.

* More command-line compatibility with apt-get for -q and
    --quiet. (Closes: #217477)

* Only override $HOME with getpwuid if $HOME/.aptitude does not
    exist.  NOTE: this doesn't work right now with the auto-su-to-root
    behavior, because that resets $HOME.  You have been warned.

* Add a sorting policy that sorts packages by version number.

- Bug fixes:

* The problem resolver will no longer try to install versions of
    packages that don't actually exist.  In particular, it won't try
    to install packages that were removed but not purged, so their
    configuration files and metadata stayed on the system.

* Eliminated a reference-to-freed-memory segfault caused by passing
    unsafe references to widgets around. (Closes: #331400)

* Don't crash when the user asks to see the changelog of a
    non-installed package.  (Closes: #331245)

* Don't crash when the cache is closed while a changelog is being
    downloaded (for instance, if a changelog is downloaded while
    packages are being installed).

* Encode match results as std::strings instead of const char *s, as
    some of the buffers are destroyed before the get_match routine
    exits.

* Don't reopen the cache after a download unless it's necessary.
    (Closes: #332708)

* Version items are now styled in the same way as package items.

* Explicitly keep the search dialog alive while its Ok handler is
    executing, so that the "actually search" signal isn't disconnected
    too soon and searching by clicking Ok works.  (Closes: #332179)
    Similar fixes to other stock dialogs.

* Use the right encoding when converting the name of a dependency
    type to a wide character string.  (Closes: #331199)

* Write out the descriptions of solution elements using
    wide-character functions.

* Ensure that string inputs in the configuration dialogs are always
    visible. (Closes: #331200)

* Read the debtags vocabulary file from /var/lib instead of
    /usr/share, and hint that the user should install debtags to make
    the error go away. (Closes: #331408)

* Fix the parser of the backwards-compatibility filter grouping
    policy. (Closes: #331404)

* Really bypass the authentication prompt if Ignore-Trust-Violations
    is true. (Closes: #332883)

* Don't duplicate packages in the filter policy.

* Accept archive or version specifiers with installauto (+M) as well
    as install.

* Document ~t.

[2005-09-30]
Version 0.3.4                           "Up The Airy Mountain"

- New features:

* The solution examiner is now a view coequal with package trees and
    other views rather than a pop-up dialog box.

* From the solution examiner, you can select individual actions
    within a solution and approve or reject them to influence the
    future course of the resolver; you can also access quite a bit
    more information, such as explanations of why actions were
    included in the solution and alternatives to the actions.

* Rebalanced the default resolver weights to focus it more on
    generating a solution quickly and less on generating a "good"
    solution.

* The problem resolver now understands about Recommendations.  It
    will try to solve Recommendations that are currently satisfied or
    that are only present in a newly installed version of a package
    and not the current version, but it can also leave them broken
    (with a penalty to the resulting solution).

* The visual mode of the program is now threaded: in particular,
    long-running tasks such as downloading packages and resolving
    dependencies are run in the background and no longer cause the
    interface to become nonresponsive.

This also eliminates the need to use recursive main loops, and
    hence this Closes: #136973.

* Holds are now implicitly cancelled by the "Keep" command in visual
    mode (but not from the command line). (Closes: #326949)

* Search patterns now treat whitespace as a term separator (but
    whitespace between a pattern code and its argument is ignored).
    To search for literal whitespace, use double quotes or
    tilde-escaping.

* You can now search for text in internal text pagers (for instance,
    when viewing a package's Changelog).

* A generic grouping policy based on search patterns is available.
    (Closes: #156065)

* Selecting a package version other than the current version and the
    default candidate version explicitly is now sticky. (Closes:
    #158771)

* Debtags support is available: tags are shown after a package's
    description, you can search for them (~G), and a tag-based grouping
    policy is available. (Closes: #243830)

* More predefined package views are available: a flat view and a
    view based on debtags.

* The command-line now has "keep" and "keep-all" commands (the
    latter cancels all sticky actions that are queued on packages).
    (Closes: #312923)

* From the command-line, changelogs can be downloaded by source
    package name in addition to the binary package name.

* The command-line option "--schedule-only" will write the
    commands you ask for to the database and then exit without
    downloading, installing, or removing anything.  (Closes: #312249)

* You can search both backwards and forwards (the backslash key
    has been changed from 'repeat last search' to 'search backwards').
    (Closes: #323239)

* You can repeat searches in all pagers and dialogs.
    (Closes: #270699)

* You can now find downgraded packages using "~adowngrade".

* aptitude now works with the apt status reporting patch from
    Michael Vogt.

* The rather useless "missing" grouping policy is no longer
    necessary and has been deprecated, although it is still recognized
    by the parser for backwards-compatibility.

* You can now access the default background color under the name
    "default" when altering styles.

The default foreground color is unavailable; for technical reasons
    it's impossible for aptitude to support both at once in a standard
    X terminal.  However, I believe that most of the requests for this
    feature stemmed from an interest in terminals with transparent
    backgrounds; if you set the default widget style to "bg default;",
    aptitude should work reasonably well with transparent terminals
    now.  (Closes: #161872)

* Every combination of the package state and the highlighted status
    of the package now has a separate style, which should allow a
    great deal more flexibility for people who don't like the
    defaults.

* aptitude now automatically keeps a single backup of the pkgstates
    file, in the same manner as dpkg. (Closes: #316460)

* Warn the user once when they modify the cache while the program is
    in read-only mode.  (Closes: #175408)

* The resolver keystroke hints at the bottom of the screen dim out
    when they're not available.

* Menus and menu bars behave more gracefully on small terminals:
    menus can be scrolled up and down, and menu bars can be scrolled
    left and right.

* You can automatically purge packages which are removed because
    they are unused.  This option is dangerous and it is recommended
    that you leave it off.  (Closes: #275150)

* Timestamps in the aptitude log file include the time zone.
    (Closes: #318501)

* If libparse-debianchangelog-perl is installed, aptitude will parse
    changelogs and highlight newer versions of the package. (Closes:
    #290692)

- Bug fixes:

* aptitude no longer goes bonkers when you suspend and resume it.
    (Closes: #137311, #169479)

* Use the password database instead of $HOME to find the user's home
    directory; this will fix the mode 0700 root-owned files that
    people were seeing.  (Closes: #272429, #274216, #285334)

* Temporary files and directories are created in /tmp instead of
    cluttering ~/.aptitude/.tmp. (Closes: #146485, #245348)

* If becoming root fails, re-load the file containing the current
    selections so that they don't get lost. (Closes: #281232)

* ~akeep now matches any package that no action will be performed
    on, including packages that are not installed.

* The apt error dialog now properly appears every time errors occur.

* Fix several UTF-8 related display bugs. (Closes: #317115)

* The cursor is now placed correctly again.

* Get the width of the screen right in a number of places when
    running in command-line mode. (Closes: #230187)

* Set packages that were to be removed because they were unused back
    to manual mode when the user keeps them at their current
    version. (Closes: #278490)

* Various bugs in the resolver fixed.

* Fix a crash that occurred when aptitude got EOF on standard input;
    the program now just aborts. (Closes: #318749)

* Fix a redundancy in some text at the command line. (Closes: #318396)

* Don't segfault if errors are encountered in the initialization
    routines. (Closes: #309445)

* When there are currently broken packages, print an explanation of
    why the command-line upgrade is aborting instead of just silently
    terminating. (Closes: #316027)

* Fix the return value of 'aptitude clean'. (Closes: #274098)

* Terminate abnormally if the user tries to show a non-existant
    package or if other errors come up. (Closes: #301291)

* The startup progress bar no longer hangs around too long.

* The message displayed when the installation procedure encounters
    errors is somewhat more levelheaded. (Closes: #230188)

* Add support for making the command-line mode "quiet" (option -q).
    (Closes: #217477)

* If -s is passed on the command-line, the cache will always be
    opened read-only, even if the user is root.

* Hold onto the apt lock while running reportbug, so we don't have
    to reload the cache and discard user selections. (Closes: #304748)

* Don't use terminal tricks to display continually updating progress
    indicator if stdin is not a tty. (Closes: #276767)

* For some years now, aptitude has not freed memory belonging to
    widget objects.  This is now fixed, and an explicit memory
    management model for widgets based on reference-counting has been
    hammered out.

* Fix the manpage's SEE ALSO entry for the reference manual.
    (Closes: #265723)

* Apply typo fixes for the documentation. (Closes: #268916)

* Explicitly document that ~a only matches the current state of a
    package. (Closes: #311290)

* Delete some unnecessary text that both lacks a trailing newline
    and is rather rude. (Closes: #295924)

- Translation updates:

* Czech (Closes: #330014)

* Danish (Closes: #317824)

* Finnish (Closes: #316225)

* French (Closes: #318906)

* Romanian (Closes: #318947)

* Vietnamese (Closes: #316994, #319702, #322276)

- Internal changes:

* Migrated all build scripts to automake-1.9 and the latest gettext
    version.

* Restructured the resolver code to be far more legible.

* Much optimization of the problem resolver, including:
    - Detect logical conflicts to avoid going down the same blind
      alleys over and over.

- Use shared-memory data structures to greatly decrease virtual
      memory usage (memory usage in test cases that used to take
      hundreds of megabytes is now negligible).

- When ordering solutions, use the score first (since it's
      essentially a hash of the information in the solution), and only
      examine the incoming solutions in their entirety if they have
      the same score.

* Split the horrible download code into a much more pleasant group
    of "download process" classes with an interface that's generic
    enough to allow the frontend to implement a general "execute
    download process" function.  The new download classes were pushed
    down into the generic level.

* Split generic/ into generic/util and generic/apt.

* Restructured the way grouping policies and matchers are parsed to
    allow them to work together without unpleasant surprises.

* A test suite (based on cppunit) is now available; most of the
    tests are currently of backend code.

* Most dynamic casting in menu_tree was eliminated; now it just
    checks whether the selected item implements the menu_redirect
    interface and proxies for it (as far as the package and solution
    item menu commands go) if so.

* Exceptions can now dynamically generate a program backtrace --
    however, in order for this to be useful, you have to have many
    more symbols compiled into the program (in tests, this DOUBLED the
    final executable size).  To get a binary that will generate a
    backtrace for uncaught exceptions, compile with
    --enable-dynamic-backtrace.

[2005-07-04]
Version 0.3.3         "Universal Text Format Ate My Package Manager"

- New features:

* Full support for UTF-8 and other wide character locales.  Anything
    that doesn't work (aside from bug #316663 in curses) is a bug.
    Some languages might lack full support, as I'm releasing this
    before the translators have time to catch up!

* Colors and text styles are now selected in a much more flexible
    way.  Each visual can independently alter or override each setting
    of its surrounding text.  Foreground and background colors can be
    set independently.

- Translation updates:

* Chinese (Simplified) (Closes: #314330)

* Chinese (Traditional) (Closes: #311587)

* Czech (Closes: #314328)

* Slovak (Closes: #309824)

* Spanish (Closes: #313412)

* Vietnamese (Closes: #313321)

- Bug fixes:

* Fix a case where different packages would be selected on startup
    than on shutdown. (Closes: #315359)

* Fix several longstanding coding errors that caused the progress
    bar to disappear/freeze while the program was starting up.

* Don't crash when trying to display information about packages
    with no Archive.  (Closes: #312533)

* Allow the user to cancel a media change.  (Closes: #315885)

* Be more explicit in warning the user that they are in read-only
    mode.  (Closes: #313417)

* Typo fix in cmdline_prompt (Closes: #313322)

* Adjusted the input polling frequency in the download code; the
    program should feel a bit more responsive while it's downloading.

[2005-05-01]
Version 0.3.2         "Eat cold logic, feeble dependency problem!"

- New features:

* Finally tossed the APT problem resolver over the side.  aptitude
    now has its own problem resolver, with (among other things) the
    following features:

- It's restartable and nondestructive -- meaning that if you
        don't like its suggestion, you can ask it to find another one.

- It understands how to resolve dependencies by installing
        non-default package versions.  For instance, it can figure out
        that to install aptitude from experimental, you need to also
        install apt and synaptic from experimental (if unstable's
        synaptic is installed).

- The priorities of the resolver are fully configurable; see the
        configuration file section of the reference manual.

- It's generic: in theory you could apply the code to many
        package systems, including some that are not APT-based.

- It has a formal model of dependencies underlying it; see
        src/generic/problemresolver/model.tex (although not all my
        notes have migrated into the LaTeX source yet; this will be
        fixed in the future).

* Implemented my proposed description formatting extensions of
    http://lists.debian.org/debian-devel/2005/03/msg02770.html --
    aptitude now detects and appropriately formats most bulleted
    lists in package descriptions.

* From the confirmation prompt (and now the resolver prompt) of the
    command-line mode, you can now additionally keep packages back
    (without setting a hold), mark packages as automatic or manual,
    and simultaneously install a package and mark it as manual.

* ~ahold now matches only packages that have a "sticky" hold set.
    ~akeep will find packages upon which no action is being taken.  To
    get the old behavior of ~ahold, use ~U~akeep.  (Closes: #216730)

* A brief summary of the currently-open views now appears at the top
    of the screen when multiple views are open.

* Merged command-line support for apt-secure from 0.2.15.9.

- Bugfixes:

* Don't discard messages about how to resolve a problem with loading
    the cache file.  In particular, the dialog box that you get if
    dpkg was interrupted should make a lot more sense.
    (Closes: #160418)

* Actually process the message about failed downloads using fragf.
    (Closes: #298713)

* Fix the "help crashes" bug.  (Closes: #293935, plus all the other
    bugs reported by people who don't check the BTS first)

* Hard-wrap, don't clip, long literally formatted lines (in
    accordance with Policy).

* Text in a number of places is now automatically formatted instead
    of having hard-wired line wrapping.

* Fixed the formatting and size calculation of fragments even in the
    presence of indentation.

* Made the description widget (and other similar widgets) actually
    cache its formatting, rather than recalculating it every time the
    screen is redrawn.

* Centralized the detection of the terminal width when running in
    command-line mode; previously, some commands would properly wrap
    text, but others wouldn't.

* Don't abort, just print a warning if the user passes -s in
    interactive mode.  (Closes: #243192)

* Fixed an ugly problem with the docbook documentation -- instead of
    using the DTD on the user's system, it was loading it off the net
    (merged from the stable branch).

* Correct the documentation of Delete-Unused (merged from stable).

[2005-01-10]          "Ow, my thesis!
                       That's funny, it didn't hurt that time..."

- Bugfixes:

* (sort of) fixed a bug which caused aptitude to want to remove
    stuff installed with another package manager.  In order to trigger
    this, you would have to remove the package with aptitude, quit
    aptitude without installing or removing anything else, then
    install the package in the other package manager before running
    aptitude again.

The caveat on the fix is that if you ^C aptitude between removing
    the package and reloading the cache, you can still get bitten.  A
    more proper fix may be included in a future aptitude version.

- New features:

* By default, aptitude will only pause after a download if errors
    occured.  Both of the old settings (always/never pause) are still
    available.

* "autoclean" will tell you how much stuff it cleaned up.  For
    technical reasons, "clean" cannot easily produce the same
    information.

- Internal changes:

* Ported aptitude to libsigc++ 2.0.

* Various bits of text are now displayed as fragments instead of
    labels, so they get properly word-wrapped and so on.  This work is
    ongoing and has revealed some structural weaknesses in fragments
    that need to be fixed before entrenching them too much.

[2004-12-21]
Version 0.3.0         "Let it snow, let it snow, let it snow"

This is the first release of a new development branch, forked from 0.2.15.8.

- Bugfixes:

* The buttons in the search dialog are properly centered.

* Internal errors that are generated because of bad formatting
    characters are less cryptic.

- New features:

* Support for apt 0.6's security features: aptitude will flag
    packages that are untrusted, and will warn you if you try to
    install an untrusted package or upgrade from a trusted to an
    untrusted version.  The warnings are currently quite obtrusive and
    strongly worded, and cannot be turned off.

- Internal changes:

* Completely redesigned widget layout to better accomodate widgets
    whose width and height are interrelated.  The new system
    completely allocates widths before allocating heights, allowing
    stuff like word-wrapped text to be handled sanely.

- Translation updates:

[2004-03-26]
Version 0.2.15.9      "I see you see we all see C see sea"
- Bugfixes:
  * Correct the English documentation of Aptitude::Delete-Unused;
    its description of this option's behavior was exactly the
    reverse of what actually happens!

* Fix a trivial typo that caused an unsightly disfigurement
    of the Search dialog.

- Backports from aptitude 0.3.x:
  * aptitude now compiles cleanly against APT 0.6, with full support
    for package trust.

[2004-09-28]
Version 0.2.15.8      "UTF-what?"
- Bugfixes:
  * Patch from Konstantinos Margaritis to "fix" the UTF-8 problem with
    a sledgehammer: if aptitude sees UTF-8 in the locale, it will
    set the locale to C instead.

* Under "Suggested packages", only show packages that something suggests.
    (previously, other relationships -- such as Replaces or Conflicts --
     were causing stuff to end up there).  (Closes: #270667)

* Belatedly apply a very old patch to improve saving Minesweeper games
    and to add some sanity-checks to Minesweeper.  (Closes: #179533)

- Translation updates:

* French (Closes: #272824)

* Italian (Closes: #265243)

* Japanese (Closes: #272454)

* Russian

[2004-09-17]
Version 0.2.15.7      "Kerplop"
- Bugfixes:
  * Use the candidate version to look for stuff to install; this makes
    installation via patterns work better.

* Parse priority strings up-front, and accept either an English string
    or the string in the current locale.

* Fixed a segfault that occured if the %r escape was used.

* Fix several potential (unreported, perhaps un-triggerable) segfaults
    in the table code.

* Various documentation fixes (Closes: #269102, #269100).

[2004-08-06]
Version 0.2.15.6      "Brrrrrrr"
- Bugfixes:
  * When displaying the size change in a single version, use '+'
    for increases and '-' for decreases rather than the other
    way around.

* "make install" installs localized manpages in $mandir now (thanks
    to Sebastian Kapfer for pointing out that this wasn't happening)

- Translation updates:
  * Czech (Debian bug #262524)

* Danish (Debian bug #262129)

* Dutch (Debian bug #262000)

* Finnish (Debian bug #263313)

* German (Debian bug #262534)

* Italian (Debian bug #261819)

* Portuguese (Debian bug #261502)

[2004-07-25]
Version 0.2.15.5      "Is it just me, or is it freezing in here?"
- New features and bugfixes:

- 'aptitude moo' no longer insults the user, even under extreme provocation.

- It is now possible to log to multiple destinations. (Debian bug #259714)

- A format code (%i) has been added to display policy information about
    package versions (ie, the priority to which they are pinned).
    (Debian bug #240423)

- An option has been added which disables some of the sanity checks
    performed prior to installing packages: the program will proceed
    to the preview screen if any packages are upgradable, even if they
    aren't being upgraded. (Debian bug #260590)

- Undoing "forget new" works again.

- Scrolling in pagers scrolls by the correct amount now. (Debian bug #260713)

- You can once again enter an empty limit string to reset the limit.
    (Debian bug #260244)

- Changed (completely useless at the moment) creation of a pthreads
    mutex to compile on FreeBSD.

- Translation updates:

- Brazilian (Debian bug #260953)

- Catalan (Debian bug #261095)

- Czech (Debian bug #259966)

- Dutch (Debian bug #260632)

- Italian (Debian bug #261017)

- Greek (Debian bug #261029)

- Portuguese (Debian bug #261425)

[2004-07-15]
Version 0.2.15.4      "Flying Space Cucumber"
- New features:

* Recommended (but not installed) packages are shown in both previews
    now.

* Suggests-Important is back as a synonym for Keep-Suggests.  This
    should smooth out the transition for people who were using it.
    (Debian bug #259387)

* Changelogs can be viewed from the command-line.

* When downloading a package from the command-line, you can select
    the version to be downloaded. (Debian bug #160145)

* Added a menu/keyboard command to search for the next broken package.
    (Debian bug #162474)

* Extended the package menu with options to manipulate a package's
    automatic flag, view its information, or view its changelog.

* Dependency patterns can now match on any dependency field; see the
    documentation for details.

- Bugfixes:

* Several potential and actual memory leaks in the command-line code
    were fixed.

* The command-line mode now complains loudly in some places where it
    used to fail silently.

[2004-07-13]
Version 0.2.15.3      "Release Roulette"
- New features:

* When displaying aptitude's explanations about dependency
    situations, packages that are unavailable will be marked as such.

* Some messages from the command-line mode (eg, about packages that
    are already installed/removed) are now suppressed unless you pass
    -v on the command-line.

- Bugfixes:

* Document the Yes/No commands.

* Return the newest version available from visible_version(), which
    should make changelog viewing and a few other things work in a
    less obscure fashion.

* Correctly initialize the menu autohide setting (Debian bug #258688).

* Suppress self-conflicts more vigorously (Debian bug #258533).

* Fixed a number of bugs related to undos; they should work much better
    now (in particular, undoing an upgrade command will work reliably).

* The tracking of automatic packages is somewhat smarter about
    versions: if upgrading a package causes it to become unused, it
    will be held back; if a package is being removed because it is
    unused and something depending on its current version is
    installed, the package will be held even if it could be
    upgraded. (say that five times fast!)

Basically, aptitude won't randomly remove packages that you try to
    upgrade because they're suddenly "unused"; instead, it will refuse
    to upgrade them.

- Translation/i18n updates:

* Miroslav Kure heroically translated the entire DocBook manual into
    Czech, along with general updates to the Czech translation.

* The keybindings for Yes and No are now translatable (Debian bug #258409).

* Split the English manpage into a separate XML file (Debian bug #259089).

* Brazilian translation update (Debian bug #258667).

* Greek translation update (Debian bug #258805).

* French translation update.

* Spanish translation update from Rubes Porras (Debian bug #258243).

[2004-07-07]
Version 0.2.15.2      "Configure this!"
- New features:

* Added a configuration option Aptitude::Keep-Suggests.  This will
    cause automatically installed packages to stay on the system if
    any installed package even Suggests them.

* Added a command-line argument -o; this behaves in the same way as
    the apt-get -o command-line argument.

- Bugfixes:

* Fixed a very old bug in configuration handling.  This version of
    aptitude will only save configuration options that you have
    modified in your personal file.  (this includes options that you
    changed and re-set to their default values) This means that future
    changes in aptitude's default settings will be picked up by most
    people; right now you will only see changes to the defaults if
    you've never used an Options dialog.  You may want to revert your
    options to the defaults to take advantage of this feature.

(Debian bug #175409)

* Fixed the manpage synopsis: it said forbid-upgrade instead of
    forbid-version. (Debian bug #257901)

* Removed an accent that accidentally crept into an image filename
    in the documentation.

* In the Vertical-Split theme, version numbers are hidden by default
    (there isn't room for them on a standard terminal)

- Translation updates:

* Updated Finish translations (Debian bug #257902)

* Updated Italian translations (Debian bug #257710)

[2004-07-04]
Version 0.2.15.1      "Obligatory July 4th reference"
- Bugfixes:

* Fix a segfault that occured in certain (undetermined) circumstances:
    a codepath that never ran on my computer would inevitably dereference
    NULL.

* Include all the screen-shot images.

[2004-07-01]
Version 0.2.15        "Daniel's Adventures in the Land of DocBook"

- New features:

* aptitude now has a "proper" manual, or at least the first iteration
    of one.  It weighs in at ~7000 lines of DocBook (which is less
    impressive than it sounds, since most lines of DocBook are fluff)
    and generates HTML pages, text documentation, and a manpage from
    a single source.

* You can now keep a package at its current version without setting a
    sticky hold by pressing ':'.

* A new %-escape for the display format, %Z, has been added.  It
    displays the change in disk usage due to an individual package (or
    version); the default package format uses it.

* Several new menus added: you can now change a package's state or
    search for a package from the menu.

* A convenient keybinding for reporting a bug has been added.

* Matchers for reverse dependencies are now much more powerful;
    matchers for reverse and forward provides are available.

* Passing -v to an installation command will display packages that are
    suggested and won't be installed.

* You can now retrieve information about a package from the command-line
    mode's prompt.

* "aptitude show" will display a package's Essential flag.

* The new "--visual-preview" command-line option uses the visual mode
    to handle previews and downloads for command-line actions.
    (Debian bug #253335)

* aptitude should now display translated task descriptions; thanks
    to Denis Barbier.
    (Debian bug #203725)

- Bugfixes:

* aptitude now handles limits that match no packages more gracefully.

* All traces of Suggests-Important were removed. (Debian bug #245410)

* aptitude should compile with g++ 3.4 now.

* aptitude now looks for unused packages on startup, so the old behavior
    (where some package states would be illogical and "snap" to the correct
    values as soon as you did anything) no longer occurs.

* Handling of automatic/manual packages was tweaked in a few other
    ways; handling of automatically changed packages was also tweaked.

* Completely disabled the use of the severely broken non-hierarchical
    view; the categorical browser just uses a hierarchical display now.
    (Debian bugs #120978, #144079, #144083, #151437, #242397)

* Undoing the "forbid upgrade" command should work in all cases now.

* Removed trailing periods from all menu item descriptions.
    (Debian bug #244676)

* Fixed compilation on all 5 existing ia64 systems (Debian bug #243932).

* If the user tries to remove an essential package but then cancels
    the removal, aptitude no longer displays an ominous warning about
    removing essential packages.  (Debian bug #254422)

* Fixed the display of ORed dependencies in "aptitude show".
    (Debian bug #254740)

* Menus are now sized more intelligently; text within menus is laid
    out slightly better.

* When a very narrow terminal is being used, menus should be displayed
    a bit more gracefully.

* Fixed some bugs with rebinding keys.

* Removed references to some obsolete (unused) keybindings and colors.

* There is now a space between the current and candidate versions in
    the default display format.

* Widget alignment within a row is now written as "top" and
    "bottom", not "left" and "right".

* Reverting options affects the user's configuration file
    immediately.

* "aptitude show" no longer performs a search unless the input
    contains a tilde.

* Fixed the display of ORed dependencies when describing reasons
    for a package's state. (Debian bug #242663)

* Improved the calculation of reasons for a package's state in the
    presence of virtual packages. (Debian bug #244817)

- Translations:

* Basque updates (Debian bug #244858)

* Brizilian updates (Debian bug #242332)

* Catalan updates (Debian bug #248764)

[2004-04-03]
Version 0.2.14.1      "Spit and polish"

Thanks to Christian Perrier <bubulle@debian.org> for helping to triage
the large pile of new and updated translations that appeared in this
release.

- Bugfixes and new features:

* You can now forbid aptitude to automatically select a particular
    package version in an upgrade.  This is mainly meant to make
    situations where a known-bad package is in unstable easier to handle.
    This functionality can be accessed via "F" in visual mode, or via
    the "forbid-version" command-line action.

* Several more improvements to how autoinstalled packages are
    handled.  In particular, you no longer have to chase the whole
    dependency tree if you de-select and then re-select a package with
    many autoinstalled dependencies.

* Save whether packages are currently going to be upgraded in the
    state file (separately from whether the package should be
    installed at all).

* If the preview screen will be empty, an explanatory dialog is
    displayed instead of a blank screen.  If it looks like the user
    just forgot to press "U", suggest that.

* Added a "reinstall" command-line action. (Debian bug #240225)

* Added a "%t" formatting escape which displays the Archive of a package.
    In addition, "aptitude show" with verbosity>1 will display Archive
    information. (Debian bug #113354)

* aptitude now supports the Key attribute of tasks (Debian bug #202781)

* Fixed fetching ChangeLogs for classes with epoched versions and
    for non-free/contrib packages.  (Debian bugs #237340, #233855)

* Manpage proofreading and polishing from Danilo Piazzalunga.
    The reference to apt-get(8) has been corrected, and -t is documented.
    (Debian bugs #198891, #225053)

* Fixed the names of download views in the View menu.
    (Debian bug #234041)

* Use fragment-based layout instead of a vs_pager to display error
    messages.  This means that they will wrap to the terminal
    width. (Debian bug #233923)

* In the dependency ("d") and version ("v") lists, the description
    of the selected package is now visible by default.

* Added section descriptions for the new archive sections.
    (Debian bug #233913)

* Information on Provides is now included in the package information
    display and in "aptitude show".  (Debian bug #121979)

* Upgrades from security.debian.org should go in a separate
    top-level tree.  (note: this is untested!)  Also, re-ordered the
    toplevel trees.

* Avoid destroying all visible widgets without quitting in some corner
    cases. (Debian bug #233783)

* Removed some text that was being ignored anyway from the
    definition of the "miscellaneous" options dialog.  I would have
    left it alone, but I think it could theoretically cause a problem.
    (Debian bug #233528)

- Translation updates:

* Brazilian Portuguese program translation update.
    (Debian bugs #237866, #199306)
  * Czech translation update. (Debian bug #240604)
  * Danish program translation update. (Debian bugs #230642, #234805)
  * Finnish program translation update. (Debian bug #238188)
  * French program translation update. (Debian bug #237501)
  * German program translation update. (Debian bug #233917)
  * Italian translation update. (Debian bug #239915)
  * Japanese program translation update. (Debian bug #235256)
  * Japanese translation update. (Debian bug #239242)
  * Lituanian translation update. (Debian bug #240683)
  * Norwegian Nynorsk translation update. (Debian bug #241104)
  * Partial Greek program translation added. (Debian bug #237808)
  * Partial Traditional Chinese program translation update. (Debian bug #230893)
  * Portuguese program translation. (Debian bug #239171)
  * Simplified Chinese translation update. (Debian bug #240739)
  * Spanish program translation update. (Debian bug #234537)

[2004-02-15]
Version 0.2.14        "I say a package, and you say ah pahckahge"

- Bugfixes and new features:

* Several command-line actions no longer crash when sources.list is
    missing or unreadable.  In addition, if sources.list is present but
    unreadable, the visual frontend no longer crashes. (Debian bug #220732)

* Fixed the detection of packages broken by conflicts.

- Build system and internal changes:

* Use AS_HELP_STRING to format help output from configure.

- Translation updates

* Italian updates (including a manpage translation) from Danilo Piazzalunga.

* Fixed the translation of a format string in the Czech translation, which
    was causing segfaults.

[2004-02-13]
Version 0.2.13.9999.3 "Sisyphus Boulder Transportation and
                       Delivery Engineers, Incorporated[tm]"

- Bugfixes and new features:

* In the information area for packages, a note about disk usage
    is printed (eg, "This package will be upgraded for <v1> to <v2>,
    using 1111kB of additional disk space.")  Useful for sending
    bug reports to maintainers who accidentally upload unstripped
    binaries of their latest package version.

* (undocumented) Experimental support for "filling" some text to the
    screen width; set Aptitude::UI::Fill-Text to True to use this.

* An FAQ is now shipped with aptitude.  I could only think of two
    questions, but I expect that more will be asked over time.

- Build system and internal changes:

* aptitude can now be compiled with g++ 3.0.  g++ 2.95 is not
    supported due to at least one nasty bug in its STL which prevents
    aptitude from compiling.  However, compiling with g++ 3.0 is enough
    to get a woody backport.

- Translation updates:

* Further Italian updates from Danilo Piazzalunga.

* Spanish translation updates from Ruben Porras.

[2004-02-08]
Version 0.2.13.9999.2 "Polar Eclipse"

- Bugfixes and new features:

* Further enhancements to the new information display.  It now shows
    any packages that are broken "because of" the currently selected
    package.  In addition, the information is colorized (if the
    terminal supports it) to give a better idea of why dependencies
    are broken.

* The information area will automatically switch to showing
    dependency information when a package breaks (press 'i' to switch
    back).

* Fixed the changelog fetching code. (Debian bugs #103455, #208041)

* aptitude no longer automatically holds packages in any
    circumstance; packages can be automatically kept back, but this
    doesn't persist the way hold does.  (Debian bug #149161)

* Added support for a "show" action on the command-line.

* Invalid patterns no longer crash the search function.
    (Debian bug #214245)

* Downgrades are now written to the log.  (Debian bug #222583)
    Patch from Danilo Piazzalunga.

* Scrollbars are now clickable.

* Many minor changes not mentioned here; see ChangeLog for the gory
    details.

- Internal changes:

* Removed the HAVE_LIBAPT_PKG3 macro: this was intended to support
    compiling against old apt versions, but those versions are now
    ancient, and the program doesn't compile against them anyway.
    Even if you wanted to, aptitude relies on having a newer version
    of g++, while older apt versions won't even compile on modern g++
    versiosn.

- Translation-related changes:

* zh_CN translation of help.txt added (also from Carlos).

* pt_BR translation updated (Andre Luis Lopes).

[2004-02-03]
Version 0.2.13.9999 "It goes ZIP when it moves!"

- Bugfixes and new features:

* Don't abort loading the cache if apt generates warnings, such as
    the warning that a new source is available.  This means that
    aptitude doesn't behave pathologically when you add a new line to
    sources.list.  (Debian bug #143732)

* Holding a package back or clearing a package's hold flag no longer
    affect the auto-install flag.  (Debian bug #159582)

* Expanded the "reason" information that can be shown about
    packages, and hooked it into the visual interface (the preview
    display will show this information automatically)

* In previews, include a list of packages which are not installed
    but are suggested by packages that are being installed.

* Entering the Preferences dialog for the first time no longer
    causes Suggested packages to be automatically installed.

* Fix the way that options set via the dialogs are saved.
    (Debian bug #216268)

* Added a scrollbar for the package description.

* Added padding between the labels of options and their settings (in the
  * preference dialogs)

* Removed the idempotency option from the dialogs.

* Removed ~e: it was broken, inelegant, and superceded by regexps.
    (Debian bug #196447)

* Additional minor bugfixes and editorial changes.

- Build system and internal changes:

* Now uses autoconf2.5.

* Added a flexible system for formatting text (see fragment.cc).
    This system is now used to handle package descriptions, as well as
    a few other things.  This is a very promising addition to
    aptitude's UI toolkit, and will almost certainly be used for
    additional features in the future.  (for instance, it's about
    80-90% of the way to being able to display simple hypertext)

- Translation-related changes:

* Missing i18n markings added to many strings.
    (Debian bug #230060)

* Fixed the German translation of "limit" (Debian bug #214021)

* Added a pt_BR translation, thanks to Gustavo Silva.
    (Debian bug #214116)

* Added an Italian translation, thanks to Danilo Piazzalunga.

* Updates to da.po from Morten Bo Johansen.

* Added a Czech translation, thanks to Miroslav Kure.

[2003-06-09]
Version 0.2.13 "Pop goes the weasel"

* Fixes a number of crashes due to mishandling of memory, spotted
    by Peter Lundkvist and Sami Liedes.
    (Debian bug #192073 and #109420)

* Fix some crashes after updates, diagnosis by Peter Lundkvist.
    (Debian bug #109420)

* No longer occasionally uses the first letter of the description as
    a flag character, diagnosis by Seneca Cunningham. (Debian bug #183462)

* Translation updates to pt_BR by Andre Luis Lopes (Debian bug #195755)

* Ported to libsigc++-1.2.  Hopefully everything should work fine,
    but I can't guarantee that no problems remain.

* Added an option to disable -Werror, needed until Debian's ncurses
    implementation is fixed.

[2003-02-10]
Version 0.2.12 "O Ye of Little Faith!"
  * Compiles with g++-3.2.  (Debian bugs #166435, 177092, 177463, 178520, and
    maybe others)

* Match strings can be POSIX regular expressions.  (note that
    regular expression metacharacters which also have a special
    meaning for aptitude, such as "(", ")", and "!", must be tilde-escaped)
    (Debian bug #142450)

* You can now see how much each package's installed size changed by
    by specifying -Z on the command-line.  (only works for command-line
    upgrades so far)

* You can search for text in the internal pagers.  (Debian bug #144085)

* Fixes to formatting code (Debian bug #163749)

* When searching for packages from the command-line, you can now
    specify the order in which to sort results.

* If no version of any package could possibly fulfill a dependency,
    it is textually flagged as "UNAVAILABLE".  (Debian bug #157950)

* The quick-help bar now indicates that "g" will also remove packages.
    (Debian bug #158966)

* Disable saving/loading of packages' reinstall state, it's too annoying.
    (Debian bugs #167236, #121346)

* Bold colors can be specified in the config file (although they will
    cause problems in some contexts).  (Debian bug #168287)

* "Minor" fix to the package gc: when marking packages, follow
    pre-depends.  This fixes the bug which prevented installation of
    the new dpkg (this fix was previously introduced as a Debian revision,
    and closed bug #151701)

* Startup should be faster in certain circumstances (eg: when many new
    packages are available, or many packages have changed state)

* "aptitude install <task-name>" will install all packages in the task.
    (Debian bug #165624)

* The resize bug in curses is fixed; re-enabled asynchronous resizing.

* Equivalent to apt-get's "-t" command-line argument.
    (Debian bug #151583)  NOTE: this is untested, since I don't have a
    machine where it would have any interesting effect, but I'm setting the
    same APT option as apt-get, so it should work.  The effects on
    the interactive mode of the program are unknown at this time, use
    with caution!

* Translation updates to:
   - da.po by Morten Bo Johansen <mojo@image.dk> (Debian bug #171903)
   - pt_BR.po by Andre Luis Lopes <andrelop@ig.com.br> (Debian bug #162512)

In addition, changed the content-type of fr.po (Debian bug #156616)

* The information in the log file about how much the size changed by
    should be much more legible now.  (Debian bug #154924)

* Fixed an integer overflow when downloading really humongous packages.
    (Debian bug #171903)

* Documented "M" and "m" in the online help (Debian bugs #160936, #154000)

* Expunged all references to the "x" keybinding. (Debian bug #166571)

* Several minor fixes of bugs, memory leaks, etc.

[2002-04-21]
Version 0.2.11.1 "Data updates are my friend"
  * This release has corrections to typos and other data issues; it does
    not change a single line of code.  This should be pushed into woody.

* Merged updated Polish translations from Michal Politowski
   <mpol@charybda.icm.edu.pl>  (Debian bug #143051)

* Merged updated Finnish translations from Jaakko Kangasharju <ashar@iki.fi>

* Included information on the CVS tree (Debian bug #141371)

* Fixed the dangling reference to SEARCHING in the manpage
  (Debian bug #142651)

[2002-04-06]
Version 0.2.11 "Look Ma, No Hands!"
           aka "Hello, JoeyH :)"

* IMPORTANT: The "new" command style is now default.  The old one is
  available from the options menu, and users of previous versions may have
  it in ~/.aptitude/config.  The new style is fairly straightforward,
  and similar to dselect.  (eg: '+' tells the program to install the package
  at the most recent version, and/or cancels holds)
    With any luck, this will squeeze into woody; I don't need a whole new
  generation of users used to the old imprecise system before I change it.

* '+' on an installed package no longer reinstalls it.  A separate
  keybinding for reinstalling packages is now available, defaulting to 'L'.
  (Debian bug #183122)

* The prompt in command-line mode now allows you to enter the full UI,
  or to modify the set of installed/removed/purged packages.
  (Debian bug #136916)

* The preview in command-line mode can be more informative: it can display
  version numbers and dependency information.  (-V and -D)

* Added a -P option; passing it causes aptitude to always prompt for
  confirmation.

* Verbosity levels are now available.  Right now this only affects
  simulation (with verbosity=0, the long list of "Inst foo/Conf foo/etc"
  is suppressed)

* Many command-line options can now be given in the configuration file.
  (eg, Aptitude::CmdLine::Show-Versions for -V)

* The command-line mode now supports an "unhold" command.
  (Debian bug #137770)

* Tasks and sections now have "descriptions" which appear in the
  `package description area'.  (Debian bug #136684)

* Added a %H display escape, which expands to the hostname of the
  computer aptitude is running on.  (Debian bug #137754)

* In command-line mode, the prompt is suppressed on upgrades when nothing
  is to be done. (Debian bug #137302)

* Reinstalled packages are displayed in the preview screens again.
  (Debian bug #138120)

* Rewrote the description widget's formatting code to be reasonably
  legible; this had the side effect of fixing an otherwise tricky bug.
  (Debian bug #137783)

* Fixed a bug which made the Tasks tree virtually useless by hiding
  many packages. (Debian bug #136684)

* If the user aborts an update, reload the cache.  (Debian bug #138070)

* autoclean now defaults to false, the "safe" option.  (Debian bug #138685)

* Fixed a nasty segfault involving running off the end of the list.
  (Debian bug #136967)

* Fixed an infinite loop if the user tried to scroll the description while
  it was hidden. (Debian bug #140361)

* The "install" command-line action doesn't interpret trailing plus
  characters (or hyphens, underscores, or equal signs) in a package name
  as explicit install requests if a package by that name already exists.
    In short: "aptitude install g++" actually works.  (Debian bug #140933)

* Focus handling: you can no longer focus an empty description widget, and
  the highlight bar in the package tree is hidden when the tree loses focus.
  (Debian bug #136550)

* "aptitude --help" now documents the "download" command.
  (Debian bug #138150)

* The status messages on startup are now suppressed in the "aptitude search"
  command. (Debian bug #136873)

* When the download is stalled, "stalled" is now displayed in the progress
  bar.  (Debian bug #136520)

* The command-line mode deals sanely with window resizes.
  (Debian bug #137945)

* For obsolete and local packages, an "available" version is not displayed.
  (Debian bug #120872)

* Added a description for the "alien" section (Debian bug #136684)

* aptitude now recognizes "--version" (Debian bug #141296)

* German translation updated, courtesy of Erich Schubert <erich@debian.org>

* Thanks go to joeyh (and others) for sending in a slew of bug reports
  and suggestions.

[2002-03-02]
Version 0.2.10 "World Domination Or Bust"
  * aptitude now has support for batch/command-line mode, similar to apt-get.
    This isn't going to make everyone happy just yet, but it should cover
  most common cases.  Upgrades via this approach get all the usual benefits
  of aptitude (tracking unused packages, recommends, etc).   There are
  various other features; see aptitude(1).

* If a package matches the "never remove these packages" expression,
  not only will it not be removed automatically, but its dependencies
  are also protected.

* Documented the "p" state of packages.  (Debian bug #135112)

* Matchers now exist for upgradable and new packages.  The new meaning
  of the ~r matcher (things which would be removed due to being unused)
  has been assigned to the new ~g matcher; the old ~r meaning has been
  reinstated.  (Debian bug #135571)

* If Suggested packages are being installed by default, no packages
  will be removed automatically if something else Suggests them.  There
  are still a few odd cases here, but this is probably about as
  good as I can do for now.  (Debian bug #135956)

* There is now a menu item to mark all upgradable and not manually held
  packages for upgrade.

* Packages being downgraded are now split into their own section in the
  preview.

* Logging is now on by default; /var/log/aptitude is used.

* When Auto-Upgrade is off, packages which are not manually held are
  not displayed with "h" in the action field.

* Updated Finnish translations from Jaakko Kangasharju <ashar@iki.fi>

* Fixed a display problem in the download screen; the amount of time
  displayed in the summary always had an extra "s" appended to it.
  (Debian bug #135567)

* Removed the INSTALLATION section from the manual; however, it
  was replaced by command line options.  I'm not sure how joeyh
  will feel about this fix.  (Debian bug #136478)

[2002-02-17]
Version 0.2.9.4 "Black Holes Are Where God Divided By Zero"
  * When calculating the time remaining in a download, aptitude
  was dividing by CurrentCPS.  Unfortunately, CurrentCPS is often
  zero!  On some platforms this works anyway, but it crashes on others
  (eg, alpha)

The code now tests whether CurrentCPS is zero when generating the
  progress bar. (Debian bug #122064)

* Forget-new-on-update actually works. (Debian bug #134226)

[2002-02-10]
Version 0.2.9.3 "Curse you, gcc steering committe!"
  * g++-3 #defines _GNU_SOURCE by default, causing compilation to
  die in because it's already defined.  All #define _GNU_SOURCE
  directives are now protected.  (Debian bug #133250)

* Actually include the Polish translation of the manpage, and update
  pl.po slightly.
  (Debian bug #114396)

[2002-02-09]
Version 0.2.9.2 "Odds 'n Ends"
  * This release is because I accidentally left some uncommitted cruft on
  a computer I wasn't planning to use for a while.  I rediscovered it,
  equally accidentally, and am now releasing it officially.

* Added %M to the default column display.

* Tweaked the preview screen so that packages which are being automatically
  upgraded do not appear as being "Automatically Installed" (maybe not the best
  way of doing things?)

* Really fixed the su-to-root stuff.

* ~ahold now really does the Right Thing (same for some related stuff)
  (Debian bug #126800)

[2002-02-09]
Version 0.2.9.1 "Silence of the LANs"
  * Argh.  I left a bug in 0.2.9; marking a package as auto-installed screwed
  up undo.  Fixed now.

[2002-02-09]
Version 0.2.9 "Please Sir, Can I Have Some More?" aka
              "When Changelog Entries Attack" aka
              "Slower Than Cold Molasses"
  * This one took so long to get out and has so many bugfixes that it
   gets three release names.  Aren't you happy? :)

* aptitude now has functionality similar to debfoster/deborphan.
  It tracks whether a package was automatically installed and
  automatically marks automatically installed, but not-depended-upon,
  packages for removal.  You can of course adjust this behavior; see
  the "TRACKING UNUSED PACKAGES" section of the manual.
    (Debian bugs #122726, #102205, #114464)

* Added logic for idempotent package commands, and an option to enable
  them.  I feel that these commands are actually much more logical than
  the old-style aptitude commands.

* Packages which are held, but broken, are now visually flagged as being
  broken.  (Debian bug #120785)

* The log messages now include date/time.  (Debian bug #120874)

* Re-ordered the preview screen's grouping.  I would like feedback
  on this.  (Debian bug #128542)

* Rewrote several sections of the documentation, partly based on user
  input.  (Debian bug #126492)

* Mark all upgradable packages for upgrade before resolving any
  dependencies.  This handles a situation involving ORed version-specific
  dependencies.  (Debian bug #108379)

* Changed the symbols for collapsed/opened trees to something not
  using +/-, which seem to be ambiguous.  (Debian bugs #120890, 102033)

* When editing a string, the cursor now starts at the beginning of the
  line.  (Debian bug #120890)

* When reconfiguring packages, gracefully handle the case where
  /usr/sbin/su-to-root does not exist.  (Debian bug #130423)

* Really made translated header widths work (and I tested it this time! :) )
  (Debian bug #114401)

* Corrected a misspelling in the options dialog (Debian bug #120887)

* Updates to da.po from Morten Brix Pederson <morten@wtf.dk>

* The information bar at the top of the screen is now translatable.
  Patch from Morten Brix Pederson.

* Fixed a misspelling in de.po.  (Debian bug #123644)

* Fixed a minor display bug when a package category was longer than the
  width of the screen and the last item in the display.  (Debian bug #123652)

[2001-12-09]
Version 0.2.8.1 "Sigh"
  * Incremental search now returns the display to the starting location on
  the empty string and invalid patterns.

* There is now a matcher for packages which are not depended on in various
  ways.  (Debian bug #122726)

* The pause after a download is now optional (Debian bug #120873)

* package data moved to /var/lib by default.  (Debian bug #122334)

* Aptitude should not crash on alpha any more, at least, not the way
  it used to.

* Description of the "comm" section changed to explicitly include
  non-faxmodems. (Debian bug #121951)

* "j" and "k" were reversed in the help text.  They are now correct.
  (Debian bug #122061)

* Danish translation from Morten Brix Pedersen <morten@wtf.dk>

* es_ES.po has been renamed to es.po.  Someone who knows more about
  Spanish than me (Jordi Malloch) told me this was a better name for it.

* pt_BR.po updated from patch supplied by
  Andre Luis Lopes <andrelop@ig.com.br>  (Debian bug #122251)

[2001-11-22]
Version 0.2.8 "I Like Bunnies"
  * Better documentation for the behavior of "/" when no special search
  terms are used.  (Debian bug #120592)

* Fixes some segfaults accidentally introduced with the incsearch code.

* Incremental search is now an option (defaulting to ON)

* Added special matchers which match packages depending on another
  package.  These matchers take another matcher as an argument, so
  you can specify conditions such as "packages depending on packages
  maintained by me"

[2001-11-21]
Version 0.2.7.999 "This release will self-destruct in 10 seconds"
  * This release is a prerelease to 0.2.8, to test the new incsearch code.

* Incremental search implemented, finally.

* Don't crash if tasksel is missing.  (Debian bug #120578)

* Make sure to use the correct translated column widths all the time.
    (Debian bug #114401)

* Minor memory leak in search code fixed (it would leak a few bytes
  every time you entered a new search term)

[2001-11-20]
Version 0.2.7.3 "Boy I'm glad I'm not a turkey"
  * Categories updated to take into account many new packages in the
  archive.

* New pl translation finally merged.  (Debian bug #114396)

* Fixed reference to ~a/~A in README (Debian bug #116695)

[2001-11-20]
Version 0.2.7.2 "Ludicrous Speed"
  * Rewrote the task loader based on input from Jason Gunthorpe.
    The new version should be significantly faster, especially on
  low-end systems.  (Debian bug #116750)

* Fixed an annoying visual bug involving the page-up key.

* Added a menu item to reload the cache on demand (useful for debugging)
    This is a compile-time option and defaults to being disabled.

* The "f" key in Minesweeper mode is now documented in the online help.
    (Debian bug #120251)

[2001-10-01]
Version 0.2.7.1 "Millenium Hand and Shrimp"
  * Made it compile again using g++-3.

[2001-10-01]
Version 0.2.7 "All the zeros and ones"
  * Version number bumped, just because this is not merely a trivial bugfix,
  and the version numbers were getting silly.

* Added support for the Task header.  (Debian bug #113657)
    I'm not sure what will happen if you have task- packages as well as
    Task headers.  Probably something weird.

[2001-09-22]
Version 0.2.6.5 "Twisting arms"
  * Work around a g++ bug on arm by reversing the order of some #includes.

* Reverting options no longer sets options which had been set by the user's
  personal configuration to a blank string.

[2001-09-15]
Version 0.2.6.4 "If at first you don't succeed"
  * Loading keybindings works again.  In addition, it works correctly
  in the presence of themes.  (the keybindings defined in the theme can
  be individually overridden by the user)  Fixes Debian bug #112307

* The list of available keybindings in README has been corrected.

[2001-09-14]
Version 0.2.6.3 "More bug-skooshing"
  * When compiled without optimization, aptitude no longer crashes whenever
  a package is unhighlighted.  (I shudder to think why the optimized build
  wasn't crashing)

* move_forward_level no longer ever "falls off the edge of the world".
  This fixes the segfault reported in #112267.

[2001-09-13]
Version 0.2.6.2 "Bug-skooshing"
  * The program no longer crashes when the hierarchy editor is used.
  All known something-completely-doesn't-work type bugs are now fixed.

* Updated the package categorizations.

[2001-09-13]
Version 0.2.6.1 "Darkness over Manhatten"
  * Fixes a horrible bug in 0.2.6 which prevented downloads from working.
  (Debian bug #111950)

* The translations should be back in the package again.  (d'oh!)
  (Debian bug #111904)

* The default display is back to its usual configuration (oops)

* An option now appears in the "UI Options" dialog for the default grouping.

* The scrolling behavior of the line-editor should be more friendly.
  (it'll scroll by single characters to a greater extent)

[2001-09-08]
Version 0.2.6 "It's against my programming to impersonate a deity"
  * IMPORTANT NOTE: this version will not compile on potato.  If anyone
  cares about this, I can patch the code to not compile themes on
  potato.  (the problem is that a feature I use to load themes isn't
  available in potato's libapt)  Alternatively, some brave soul could
  patch aptitude to load themes using potato's libapt...

* Released despite the fact that 0.2.5.3 is not yet in testing.  From
  my glances at the testing bot's output, the problem is that the deity
  people are being lazy and not fixing RC bugs, which (since aptitude depends
  on a version of apt not in testing) is preventing the new apt from going
  into testing (which would break deity in testing).  And aptitude can't go
  into testing without the new apt.  Blah.
    By the time deity-devel fixes their bugs and gets recompiles for all archs
  and so on, this will be ready for testing.  I would have uploaded it a
  long time ago, had I realized what would happen.

* This version adds support for externally defined package hierarchies,
  one of the major original goals of aptitude.
    As usual, this turned out to integrate less well into the program than
  I had hoped.  Fixing this will probably require another tree-class rewrite,
  and I think I'll aim at fixing it in 0.4.x.  Anyway, though, the basic
  stuff is there.  A lot of the work, actually, was in a massive and concerted
  attempt to make a first-cut hierarchy of all the packages in sid.  This
  was successful, in the limited sense that such a hierarchy now exists (and
  is distributed with the program)  However, it has many problems and
  even some inconsistencies.  Further work on that front is needed.

The hierarchy stuff is documented in README.hier.  If you are an APT
  frontend author, please be aware that it is trivial to implement, and a
  (slow) generic implementation is available in src/generic/pkg_hier.{cc,h}.
  (this is currently the implementation used by aptitude itself)
    In other words: I want to encourage people to use this mechanism.

If you are interested in helping improve the categorizations, I suggest
  using the internal category editor (press "E" while viewing packages)  The
  Vertical-Split layout is particularly useful for this.

Efficiency is somewhat of a concern with this code; however, if you do
  not use it, it is my hope that it will never affect your use of the program.

* In addition, there is slightly hacky support for a "flat package browser".
  This goes hand-in-hand with the above change, as I found that complex
  hierarchies were actually harder (for my little mind :) ) to navigate using
  aptitude's traditional tree-based approach.  Do "New Categorical Browser"
  from the "Views" menu to try this out.

* The screen layout may now be configured by the user.  This is
  currently only available by editing configuration files, and is
  undocumented (because it's complicated, and I may change the format
  for a few revisions while I'm trying to figure out the best way
  of doing things)  See $prefix/share/aptitude/aptitude-defaults for
  some examples.

* "Theming support" is available.  A "theme" is basically a collection
  of settings that makes aptitude behave and look differently.  The only
  themes available are "Vertical-Split" (highly recommended by me for wide
  consoles or xterms, especially if you're editing package hierarchies), and
  "Dselect" (not particularly useful even if you are a dselect junkie)

* Aptitude::UI::Default-Grouping is now documented, and will not be
  used to set the grouping of a preview screen (bug #110704)

* Aptitude::UI::Package-Header-Format is now documented.

* Colors can be defined as being bold.  This cleans out a lot of evil
  cruft.

* A 'short priority' column is now available (added to support a
  dselect theme)

* autoclean-on-update works again.  (bug #108565)

* ~ahold works again.  (bug #111466)

* Several bugs in the table layout code were fixed; it should behave much
  more sanely now.

* If aptitude (God forbid!) crashes or is killed with a catchable signal,
  it will now properly shut the display down instead of leaving it in a
  screwy state.

* Fixed building on ia64 (old nasty debug code was breaking it)

* Deleted the note in the README about "Save Options"

* The configuration is now saved to config.new and moved to config using
  rename(2).  This should guard better against problems with the save process.

* Subtree names in small windows are no longer clipped to one character
  too short.

* Updated my mailing address in README and AUTHORS to @debian.org.

[2001-08-06]
Version 0.2.5.3 "I hate build errors"
  * getopt_long returns an int, not a char.  This caused signedness problems
  on powerpc.
  * time() and difftime() are in time.h.  This caused compile problems
  on the Hurd; it seems they were accidentally implicitly included on other
  platforms.
  * "make dist" no longer generates the ChangeLog automatically from RCS
  entries.  This means that I'll have to maintain it manually, but that
  REALLY beats having to download the full log for every file over a phone
  line every time I release a new version.

[2001-07-27]
Version 0.2.5.2 "Dashing away with a smoothing iron"
  * Fix an endianess problem that caused crashes on Alpha (among others)
  (Debian bug #106588)

[2001-07-24]
Version 0.2.5.1 "Hand me the brown paper bag, nurse!"
  * Using a widget with a history list no longer segfaults the program.
  Lesson of the day: never assume that a change is benign even if it couldn't
  possibly cause any problems!  (Debian bug #106378)

[2001-07-23]
Version 0.2.5 "Drop the text editor and back away slowly"
  * Multi-CD installs now work.  (Debian bug #104236)

* Mouse support added.  Doesn't do much now, but the menus and buttons will
  work with it, and you can double-click packages to see information on them.

* The download list can be scrolled left and right using the left and right
  arrow keys.

* Line-editors can now have a history list.  (used when entering search and
  limit terms, grouping mechanisms, and sorting policies)

* The prompt to enter a search term now defaults to an empty string; press
  up or Control-P to recall the previous term.

* The 'set group' command now displays the current group as a default
  entry.  (Debian bug #103962)

* The Minesweeper help screen should really work this time.

* The Install/Remove menu item does the same thing as pressing 'g' when
  a preview is selected.

* Added a line at the top of the screen listing some important keybindings,
  and removed the welcome dialog.  The welcome dialog was annoying, and
  extensive user testing (consisting of me watching over my sister's shoulder
  for about 5 minutes) revealed that people don't bother to read the
  keybinding information in it anyway.  (Debian bug #104483)

* The primary Undo keybinding (ie, the one displayed in the menu) is now
  C-u, not C-_.

[2001-07-19]
Version 0.2.4 "C++ standard?  What C++ standard?"
  * aptitude compiles with g++-3.0.  (Debian bug #104723)
  * help-fi.txt is now in CVS (it was in the distribution tar.gz, but never
  got added to CVS.  Go figure)

[2001-07-11]
Version 0.2.3 "Curse you, Peter Pan!"
  * Finally, a new version..unfortunately, aptitude 0.2.2 needs two more days
  to get into testing, and I'm going to be gone in a few days.  I want to
  upload this version significantly before the freeze, since it fixes some
  bugs and could also add some that'll have to be squashed.  So I'm going to
  say farewell to my dreams of 0.2.2 in testing, and upload this.  Maybe I
  should increase the urgency, I really don't want the version in testing
  to be released with woody.

* This version of aptitude should compile on Progeny Linux and on potato.

* aptitude can now attempt to automatically su to the root user when
  running as a non-root user.  Treat this with some care, as it's a fairly
  complex and new feature -- ie, there are probably bugs and unexpected
  behavior lurking in it.

However, this should provide an escape route in "OMG, I just spent an hour
  picking programs to install and forgot I wasn't root!" situations.

* aptitude now supports some command-line options, see "man aptitude" for
  details.

* "status bar" downloads aren't any more; "split-screen" is more
  accurate.  They display the currently active items and leave out the
  history of past downloads.

* With any luck, the media-change message should now fit on one line.
  This still doesn't handle the case where the CD name is longer than the
  screen width, but I hope it'll do for now.

* Pressing "q" while a 'status bar' download is in progress now stops it.

* If the package list is resized so that the selection would be off the
  screen, the selection will now be preserved. (Debian bug #103963)

* A package description with a word which is longer than the screen width
  will no longer crash aptitude.  (Debian bug #103691)

* Broken dependencies now have a visual marking other than color.
  (Debian bug #79047)

* If the menubar autohides and the user opted to be able to close all
  screens without exiting the program, force the menu to be visible
  anyway if no screens are active. (Debian bug #102918)

* Fixed bugs that prevented the "utils" and "hamradio" sections from having
  descriptions displayed.

* If you try to start aptitude as root while the apt cache is locked, it
  will open the cache read-only. (previously it just refused to run at all)

* A limit type based on the action to be taken with a package
  (install/upgrade/remove/purge/reinstall/hold) is now available.
  (Ted Tso's suggestion, no bug #)

* The 'action' keys can now advance the cursor to the next item at the
  current level.  They won't advance into subtrees or out of the current
  subtree; this is because it's nontrivial for me to move to the "next"
  subtree due to the design, and moving out of a subtree violates the
  Principle of Least Surprise (not to mention probably causing you to delete
  half your packages)  (Debian bug #104209)

* Pressing '?' while playing Minesweeper will actually show a help screen
  now.

* You can now run dpkg-reconfigure from within aptitude (it's a silly
  feature, but it's also about 10 lines of code..)

* When aptitude starts for the first time, it will *not* mark every
  package as new.

[2001-06-29]
Version 0.2.2 "Finlandia"
  * The Finnish translations have been updated to work with 0.2.0.  This is
  the major change in this release.

* Default widths can now be set by the translator, albiet in a slightly
  hacky way.  (you can translate a string of numbers to set them.  See
  pkg_columnizer.cc for a short description)

* A short description of each section is now displayed next to the section
  itself.  This clutters things up a bit and may be modified or removed in
  a future release.

[2001-06-28]
Version 0.2.1 "Another Fine Mess"
  * Options are now automatically saved when you hit "OK".  Let's hope I was
  overly paranoid earlier about the possible consequences of this..

* Installing from CD-ROMs works.  Amazingly, this worked perfectly in every
  release through 0.1.9 -- 0.2.0 broke it when I changed the semantics of
  popup_widget(), and I couldn't test it until I finally found a CD..

* Minesweeper's dialog boxes (new game, etc) work.  (although pressing
  Enter while Cancel is selected does the Wrong Thing..)

* The original behavior of the tree widgets has been restored: they only
  scroll one line at a time.  Personally, I find this to be much better; I
  hope you do too.

* Really fixed the signedness issues with addch() this time.  (I hope..)

* The ancient bug that caused the root of the tree to be hidden when you
  pressed End has been found and terminated (with extreme prejudice)

[2001-06-25]
Version 0.2.0 "Damn The Torpedoes, Full Speed Ahead!"
  * Ok, it took a bit longer than I expected.  Sue me.

This is the first version in the 0.2.0 "stable" series, where "stable"
means "working reasonably well".  User-visible changes from 0.0.x include:

* The UI has been completely rewritten.  Several changes below
  follow from this, but in general it allowed the interface to become
  more flexible and dynamic.

* aptitude now supports a split-screen display.  It isn't visible by
  default in all screens; press 'D' to show or hide it.

* There is a global menubar.

* The currently active views are arranged less like a stack: you can
  cycle between them or jump to a particular one.

* 'x' no longer has any function.  You cannot say "revert all
  changes I made in this display", because with a non-stack display
  model, "all changes I made in this display" doesn't make sense.

* You can read this document from within the program.

* The program options can be modified from within the program.

* You can configure the way in which packages are grouped and
  sorted.

* You can play Minesweeper from within the program.

* The download display has been entirely rewritten.  ie, it works
  now and isn't so much of a hack.

* When a package is marked for installation, aptitude can now
  install the packages it recommends and/or suggests as well.

* aptitude can now perform clean and autoclean operations.

* much, much more.  (well, maybe not.  Do I look like I know?)

Changes from version 0.1.9:

* Aptitude::UI::Prompt-On-Exit works again.

* The extended description area can be hidden by default.

* Autoclean actually works, rather than just saying that it works.

* The menubar now automatically pops up the first menu, rather than
  doing this "select the menu name" thing.

* It should now be possible to view the NEWS file from the Help
  menu.

* Removed the Test Error.

* Added src/vscreen/README.layout to the files which are included in
  the distribution.

* You now get the extended description area, status line, and so on
  in all screens, even if you access them via a version item (oops)

* The extended description no longer allows you to scroll off the bottom.

* Fixed sorting, in an only slightly ugly way.  (the configurable
  sorting was only being applied to the first level of hierarchy)

* Eight-bit characters should work again in vs_pager, I hope.

* vscreen/ compiles with g++-3.0.
    The convention I'm now using for STL classes is this: header files
  should explicitly use "std::" to access them; .cc files should
  declare "using std" (AFTER all #includes!)

* Several strings were still hard to translate because they were
  used in concatenation to produce a result.

* Menu tweaks: the "o" in "Remove obsolete packages" is now
  highlighted.

* Fixed some random deadlocks by using recursive mutexes.

* Documentation updated, although not as much as I wanted to.

Pre-0.2.0 versions:
===============================================================================
[2001-06-18]
Version 0.1.9 "Speak Now Or Forever Hold Your Peace."
  * If there are no serious bug reports about this, APTITUDE 0.2 WILL
  BE UPLOADED TO UNSTABLE IN THE NEAR FUTURE!  Therefore, if you know of
  a problem that should prevent this from being released into the wild,
  PLEASE TELL ME!  Thank you.

* There is now a header which displays various useful information.

* The views all display a header, description area, and status line.
  (previously only the main package list displayed them)

* The status line now does something slightly more sensible when no package
  is selected.  Suggestions for further refinement welcome

* Changing the status layout configuration now has an immediate effect.

* You can now have a separate limit for preview screens
  (Aptitude::UI::Preview-Limit)

* Various informational messages are displayed in the status line now if
  the "minibuffer interaction" option is set.

* Package matchers for Origin and Archive are now available.

* There is now an option ("Aptitude::UI::Welcome-Dialog") controlling
  whether the potentially annoying welcome dialog is displayed on startup.

* Various potential crashes fixed, I hope.

[2001-06-15]
Version 0.1.8 "Making a List and Checking It Twice"
  * Viewing dependencies no longer causes Aptitude to enter an infinite loop

* Added consistency checking: you can no longer perform an installation
  run if there are broken packages (the problem-resolver will run and you
  will be sent back to the preview screen)

* Aptitude can now install Recommends and Suggests when a package is
  selected for installation.  (note, however, that libapt is a little screwy
  and seems to behave incorrectly if there is an OR in the Recommends: or
  Suggests: line.  I'll work up a proper bug report when I have a chance)

This only works if Auto-Install is on.  Therefore:

* Auto-Install IS NOW ON BY DEFAULT!  I think this should be fine, but people
  should be aware of this.

* Aptitude can now perform the "autoclean" operation of apt-get.  It can
  also perform the "autoclean" operation automatically whenever packages are
  updated.  Addresses Debian bug #97653.

THIS IS ON BY DEFAULT!
  If you think having it be on by default is bad, PLEASE LET ME KNOW!
  If you think having it be on by default is good, PLEASE LET ME KNOW!

I have mixed feelings about this, because while naive users who just take
  the defaults will probably benefit from this, I feel that it violates the
  "principle of least surprise".

* Reinstalled packages are no longer listed as broken in the preview screen.

* Reinstalled packages and versions of reinstalled packages are colorized
  correctly.

* Aptitude::Log is now documented.

* Action logs are now sorted by type and package name.  In other words: it
  should now be possible to make sense of them.

* Essential packages can be selected using a matcher.

* Packages which are essential have a line saying "Essential: Yes" in
  their info screens.

* Marking an essential package for removal is now difficult (if you can get
  the problem-resolver to do it, though, the program won't complain when you
  try to remove them.  I don't think the problem-resolver will ever do this,
  though..)  Addresses Debian bug #86115

* Packages can be grouped and sorted by priority.

* Cleaning the package cache gives more feedback.

* Recommends and suggests are colored red if they are not met.

* Certain trees (specifically package installation modes and priorities)
  now are sorted in a non-alphabetical order.  For instance, with priorities,
  the highest priority comes first, followed by the next-highest, and so on.

* Fixed a crash when using ANDs in matching expressions.

[2001-06-04]
Version 0.1.7 "No."
  * Scrollbars should now be fixed in the popup pagers.  (there are still some
  visual artifacts, which I'm tempted to attribute to Curses bugs..)

* A Minesweeper game is now available in aptitude, to liven up those long
  downloads.  Select "play Minesweeper" from the main menu..

* Trying to repeat a search before a search has been performed no longer
  crashes the program.

* Many more items added to the options menu and dialogs.  Internally we now
  use static tables to build the option dialogs, which should make it easier
  to add new options to them.

* Fixed several small problems with the documentation of configuration
  options.

* A popup window now appears for the entire time that aptitude is setting
  up after loading the cache.  (it currently says "loading cache")  The real
  solution is to make this not take so long, but..

* NOTE: this version does NOT have the "don't let the user do something
  broken" code featured in 0.0.8.7.  With luck, 0.1.8 will have its own
  version of that logic.

[2001-05-03]
Version 0.1.6 "Are We There Yet?"
  * Merged with the stable branch through 0.0.8.6

* File menu renamed to Actions (since that's what it is)

* Undo re-enabled, and created an "Undo menu".  Note that undo no longer has
  the mark/revert behavior it used to -- in fact, it cannot, because the UI
  is no longer a strict stack (you can switch from one screen to another freely)

* The README can now be viewed (from within the program) from the Help menu.

* The menus and a lot more UI stuff should now be fully translatable.

* Fixed a nasty little bug where undoing one action would make all
  auto-upgraded packages revert to being held.  (backported to 0.0.8.6)

* When displaying a keybinding to the user, C-_ is displayed as C-_ rather
  than C-^?.

* Information about the currently selected item is now displayed in the
  "status bar" style, with an additional "bold" attribute.  Makes it easier to
  tell apart from, say, an extended description.

* Fixed some bugs in the logic for causing the download display to
  constantly stick to the end: in particular, the currently downloading
  item should now be on the bottom line of the screen rather than being
  off the bottom (and thus invisible)

* If ~/.aptitude does not exst when the user selects "save options",
  it is now created.

[2001-04-27]
Version 0.1.5 "Will Debianize For Food"
  * All changelog entries which are really from 2001 are now listed as being
  from 2001.  However much I wish I could stop the forward march of time, I
  don't think that's the way to go about doing it.

* Split-screen!  Ok, it's slightly hacky, unconfigurable, can't display
  anything besides the package description, and the bindings are quirky, but
  hey, the idea is there :)
    For lazy people :), 'D' shows/hides the description window and 'a' and 'z'
  move up/down in it.  'Tab' can be used to switch to it, at which point the
  usual navigation keys work.  At least, the ones I've implemented (up one line
  and down one line) work.

* A precompiled matcher is now always used to perform searches.  This not
  only makes searches (hopefully) faster, it also prevents crashes when a bad
  search term is encountered a la bug #95455.

* Packages which don't have an explicit source package listed should have
  a source package which has the same name as the package itself.  The info
  screen now makes use of this fact.

* Exiting now saves the selection info again (there's not yet an
  "exit and discard changes" -- just Ctrl-C :-) )

[2001-04-10]
Version 0.1.4 "Once there was an Elephant, who tried to use the Telephant"
  * Merged with stable up through 0.0.8.3.

* The multiplexer now jumps to the "previous" widget when the current
  one is destroyed.  The point of this is that the main aptitude display will
  act more or less like a stack again, which is a lot more convenient than how
  it was acting in 0.1.3.

* The "Cancel" button displayed after downloading packages actually works.

* When downloading stuff, the "saving extended information" progress
  bar is hidden.

* The (non-minibuffer) download screens now have an "overall progress"
  indicator.

* The status line now displays information about the currently
  selected menu item.

[2001-03-23]
Version 0.1.3 "South Blue Quickly"
  * Still a BETA DEVELOPMENT RELEASE.

* Worked around a dumb autoconf bug.

* Merged with stable updates through 0.0.8.0.

* Added a match type for versions (~V)

* Fixed a bug that caused the download-list to be updated at very
  irregular intervals.

* Added a popup after the download that claims you can continue
  or cancel.  You can't.  But it's a nice thought anyway.  (see the first item)

* Added sorting policies.  It was harder than it sounds.  See README.

[2001-02-21]
Version 0.1.2 "Erlkönig"
  * Still a BETA DEVELOPMENT RELEASE.

* How packages are grouped into the hierarchy can finally be configured!
  Currently there are only a few totally new options, but I'm sure people will
  find novel ways to brea^H^H^H^Hconfigure their systems.  Also, it's dead
  simple to add parsing for new policies (see load_config.cc and
  pkg_grouppolicy.cc)
    See the "GROUPING CONFIGURATION" section in the README for more information.

* The download screen now scrolls automagically!  This closes one of the
  longest-standing and most just complaints about Aptitude. (TODO: add a
  scollbar widget -- not hard)

* The "bytes downloaded" message shown when download completes now allows you
  to scroll the download screen behind it.  (TODO: display this as a "minibuffer"
  if the user requests it)

* Synced with 0.0.7.15, fixes various minor issues and makes the default
  grouping more sane.

* When you do a "forget new", the display is updated to reflect that fact.

* Supposedly, package-info lines should be hidden when you perform a download.
  I'm not sure this actually works..

* There's code to allow different sorting policies, not that you can actually
  use it.  (eg, sort by size..)

* Divide-by-zero errors no longer randomly happen while you're downloading.

[2001-01-30]
Version 0.1.1 "Fool!  I told you the Electric Rubber Ducky Incident
               was never to be mentioned in my presence again!"
  * Still a BETA DEVELOPMENT RELEASE.

* Updating package lists and installing packages is now possible!  This is
  still a little dicey and will improve in coming releases, but you can do it.

* aptitude now compiles (and works) with APT 0.4, in addition to APT 0.3
    No 0.4 special features are explicitly supported yet.

* configure.in now aborts if libsigc++ can't be found.

* Keybindings for the current view were incorrectly active while the menu was
  being used.  Fixed.

* You can now choose whether the menu should auto-hide, and by default it
  doesn't.

* Searching for packages is again possible.  I've tried something that will
  hopefully make it less slow..

* The apt package cache can be cleared from aptitude.

* Various crashes fixed.

[2000-12-03]
Version 0.1.0 "Release without a name"
  * This is a BETA DEVELOPMENT RELEASE.  It is not fully functional yet; please
  use older versions if you need missing features.

* The ui-rewrite tag finally belches forth a working binary!  Yes,
  aptitude 0.1.0 is here at last.  Changes are too numerous to really list, but:

* vscreen is now a full widget library based on libsigc++, supporting real
  layout, signals/slots (of course), and..um..lots of other good stuff.  Look
  at the header files for more info (yes, I'll probably eventually fork it into
  another project)

* this means that aptitude now depends (build and runtime) on libsigc++0.
    Sorry, potato users :(

* On the plus side, we finally have a (links-style) menubar.

* User-specific options (in ~/.aptitude/config) are supported, and can be
  explicitly saved by the user.

* The new version doesn't handle small terminals so well yet (and resizing
  an xterm will cause a segfault!)

===============================================================================
Pre-0.1.0 versions begin here:

[2001-06-08]
Version 0.0.8.7.1 "D'oh"
  * The limit of the preview screen can once again be modified.  Thanks to
  Michael Politowski for pointing out a simple typo.

[2001-06-04]
Version 0.0.8.7 "Home from the Hospital"
  * Displaying information about a particular package version will now use
  the description of THAT version.

* Fixed some problems with the autotools suite.

* If the user's selections in the preview screen mean that something has
  to be fixed-up, the program now does the fixing and presents another preview.
  This addresses the following Debian bugs: #87774, #96559.  It may not fully
  close them; I am not certain whether the problem in those bugs is that I
  am incorrectly displaying the state of the packages, or that the problem
  resolver is doing stuff behind the user's back.
    Note: this is NOT forward-ported to version 0.1.x; this code is different
  enough in that track that I'll have to come up with a solution separately.

[2001-05-03]
Version 0.0.8.6 "Groundhog Day"
  * Really don't save extended state info if that info was modified (I thought
  this worked in 0.0.8.4, but, doh, I actually had done it in the unstable
  branch)

* Hitting "purge" on a package version now does the expected.
  (Debian buf #96228, reported by the same JP)

[2001-05-01]
Version 0.0.8.5 "Bring Me A Shrubbery!"
  * Fixed two bugs relating to translations, reported by the ever-vigilant
  Michal Politowski:
     - Reran gettextize so that translations get installed with usable names.
     (Debian bug #95749)
     - Changed "purge" to "purged" when it is used to describe a package's
     current state.  (this lets translators distinguish between them, and is
     probably better anyway) (Debian bug #95867)

[2001-04-27]
Version 0.0.8.4 "I hate finals"
  * aptitude now only saves its extended state information if that information
  was modified (Debian bug #93135, reported by JP Sugarbroad <taral@taral.net>)

* Don't segfault when the user searches while the cursor is on the last
  item in the tree.  (Debian bug #95495, reported by
  Len Sorensen <lsorense@opengraphics.com>)

* Added description of action/state flags to online help and README.
  (Debian bug #93216, reported by Piotr Krukowiecki <piotr@pingu.ii.uj.edu.pl>)

PS - debian bug #90909, referenced below, dealt with a crash that occured when
  updating the package lists while viewing information about a package.  Sorry
  for the overly terse entry.

[2001-04-05]
Version 0.0.8.3 "Palindrome"
  * Fix Debian bug #90909, reported by Robert Bihlmeyer <robbe@orcus.priv.at>
    This bug was due to the fact that I inexplicably overrode an important
  method to do nothing.

* Added a Galacian manpage and help file.
   Thanks go to Jacobo Tarrio <jtarrio@iname.com>.

[2001-03-23]
Version 0.0.8.2 "Midterms suck"
  * Fix compile problems with apts in the 0.3 series.  (this one was actually
  tested with 0.3, so there)

[2001-03-18]
Version 0.0.8.1 "Do you know how hard it is to come up with dozens of
                 clever and witty release names?  I bet you don't!  I bet
                 no-one even reads these!  I bet it doesn't matter if I rant
                 for pages and pages and pages about teapots in the sky!"
  * Fixed a long-standing but undetected bug.  It turns out that some packages
  exist in the database but aren't available (they are called into existence by,
  for instance, a dependency on a non-existant package)  But aptitude was storing
  "sticky" state information for these packages.  This had a number of
  subtle but potentially startling consequences; among them is the
  fact that if a package of that name was eventually uploaded to the
  archive, it wouldn't show up as "new".

[2001-03-16]
Version 0.0.8.0 "Roll over, roll over.."
  * Galician translations, thanks to Jacobo Tarrio <jtarrio@iname.com>.
   (is it a sign that your program is popular when people translate it to
   languages you've never heard of?  Thank God for web1913 :) )

* Spent a few minutes figuring out how to do (non-sticky, sorry) installation
   of a particular version.  Finally those version lists do what they oughta!
   More or less.

* Incremented the third digit of the version.  Please don't laugh.

[2001-03-04]
Version 0.0.7.19 "Jubjub"
  * help-pl.txt is really installed.
  * Don't print spurious errors when the user enters blank patterns.
  * The "search again" binding now really has two values instead of just one.

[2001-03-03]
Version 0.0.7.18 "Jabberwocky"
  * Retroactively corrected NEWS entries which were in '00 but should have been
   in '01.
  * Fixed bugs reported by Michal Politowski <mpol@charybda.icm.edu.pl>
    - Accented characters in the status line are no longer displayed
     incorrectly (a stupid sign-extension bug)
    - Fixed a few cases of overeager marking of strings for translation.
    - Fixed three crashes in the parsers for matchers and limits
  * Entering an invalid limit will no longer occasionally cause dozens of
   errors.
  * Gave in and made "n" an alternate binding for "search again".
  * Added Polish translation, contributed by Michal Politowski.

[2001-02-24]
Version 0.0.7.17 "I will not make a stupid Brown Paper Bag reference here"
  * Fixed a horribly STUPID bug in the APT 0.5 support, involving me misreading
   the prototype of VersioningSystem::CheckDep and passing the arguments
   in reverse order from what it expected!  Oops.

[2001-02-23]
Version 0.0.7.16 "Brought to you by the letter F"
  * Added two new translations:
    - Finnish, contributed by Jaakko Kangasharju <ashar@iki.fi>
    - French, contributed by Martin Quinson <mquinson@ens-lyon.fr>

* Made some formerly untranslatable strings in load_config.cc translatable
   (thanks to Jaakko for pointing this out)

* configure.in now hacks around brokenness in some autoconf releases
  that caused C++ code to break.

[2001-02-01]
Version 0.0.7.15 "Coda"
  * Fixed a whole slew of bugs that Zack Weinberg <zackw@stanford.edu> was
  unfortunate to run into simultaneously:
    - Running into an error while loading the configuration no longer causes
     the program to panic and display a blank "we couldn't start successfully"
     screen.
    - Keybinding subgroups don't cause a spurious error message.
    - If startup isn't successful (and thus the package file wasn't read),
     trying to exit no longer causes a crash.  (just in case, added checks in
     several other places for NULL pointers as well)
    - The bindings for vs_tree (Aptitude::UI::Keybindings::Tree) can now also
     be reconfigured from the toplevel, as expected.

[2000-12-18]
Version 0.0.7.14 "Grouping therapy"
  * Suggestions and patches from Arto Jantunen <viiru@debian.org>:
    - Tasks are now displayed as a separate "section"
    - The hierarchy has been 'inverted'.  The primary grouping mechanism is now
     the 'subsection', with the 'top section' above it.
    - Redundant hierarchy such as "virtual/virtual" is no longer there.
    - the online help explains about the 'f' key.
  * Various bugs, crashes, and bad behavior with APT 0.4 thrashed out.

[2000-12-12]
Version 0.0.7.13 "Portage"
  * aptitude should now compile without modifications against APT 0.4.  The
  fancy new features won't be used and will probably never be hooked into this
  branch -- the long-vapoured (but still slowly approaching) rewritten version
  will be where I fiddle with that stuff.

[2000-11-27]
Version 0.0.7.12 "Bored in Providence"
  * The long-standing TODO item of allowing a single package to be installed
   without affecting anything else is more-or-less fixed, although I'm not
   sure if it's the best implementation (actually, I'm sure it probably has
   unfortunate glitches still..)  Press "I" and read about it in the README
   (although I should clear that documentation up..)

[2000-11-26]
Version 0.0.7.11 "My Grandma, what big Segfaults you have!"
  * Fix a long-standing bug that triggered a segfault-on-start in extremely
   unusual circumstances (which is how it avoided me for so long)

[2000-11-26]
Version 0.0.7.10 "I didn't do it!  No-one saw me do it!"
  * Errr...the changes in the last version included a hack to make packages
   appear in the right indentation from the left-hand side of the screen.  This
   hack also happened to cause the program to misbehave very badly in some
   circumstances (eg, when trying to download packages)  I've replaced it with
   a more invasive hack that actually works.  Oh, and I tested it this time.
   Testing things is a good idea..

[2000-11-25]
Version 0.0.7.9 "YOW!  I've been LAID OUT by a COLUMN GENERATOR!"
  * The only change in this release is a total rewrite of the column-generation
  code.  It's much less crufty and should allocate space more cleverly on
  larger displays. (this also fixes a debbts report)
    The column configuration is slightly different; if you have a custom
  configuration, you might want to check the README.

[2000-11-22]
Version 0.0.7.8 "Silence of the Turkeys"
  * Fixed a minor typo in the README reported in the Debian BTS.
  * Similarly, fixed a small interface bug with the package-limit string.
  * Finally got around to adding the delete-to-end-of-line and
   delete-to-beginning-of-line functions to the line-editor.
  * Logs of install runs now display (for upgraded packages) the version being
   upgraded from and the version being upgraded to.

[2000-10-27]
Version 0.0.7.7 "Pentecost"
  * More translations (es_ES and pt_BR) added.  Thanks to
   Jorge Carrasquilla Soares and Douglas Moura Ferreira for contributing
   these.

[2000-10-15]
Version 0.0.7.6 "Package Management for Pern"
  * Debian bug #74788 fixed: threads are eliminated if not available, allowing
   aptitude to compile on the Hurd.  (go Hurders!)

[2000-10-13]
Version 0.0.7.5 "Friday the 13th"
  * Fixed the bug reported by Jordi Mallach <jordi@debian.org>, where "x"
   had its view of its arguments backwards.  (this was introduced by the change
   in 0.0.7.2 which altered the messages displayed when saving as an
   unprivileged user)

[2000-10-11]
Version 0.0.7.4 "Ich bin ein Berliner!"
  * corrected German translations.  Hopefully .de users won't mind no longer
   being amused by my fractured Deutsch.  Thanks to Sebastian Schaffert
   for contributing these.

* Masato Taruishi has contributed a patch to internationalize even more
   strings (it is even possible to have language-specific online help,
   although no internationalized help files are written yet)  He also
   updated the Japanese translation to reflect this.  (the German translation,
   unfortunately, continues to lag behind)

[2000-10-03]
Version 0.0.7.3 "If I only had a brain"
  * aptitude now REALLY has a manpage.  (if it doesn't get installed by
   "make dist", it's not in the program..)

[2000-09-23]
Version 0.0.7.2
  * "Bug-reports keep fallin' on my head"

* aptitude now has a manpage.

* The program now works properly with local files (this was a problem
   that arose from my abuse of libapt)

* If aptitude is run as an unprivileged user, pressing "q" and "x" no longer
   mention saving anything.

* Merged in an i18n patch (thanks to Masato Taruishi for this and the
   Japanese translation)  There is a German translation done by me, but
   given the state of my German, a native speaker may want to send me
   a corrected translation.

[2000-08-03]
Version 0.0.7.1
  * "Faster than a speeding river of molasses" release.

* The lengthy hiatus here was due to the fact that I was originally
   planning to fix a bunch of cruft and release quickly towards the
   beginning of the summer <sarcastic laughter>  Then I decided to rewrite
   the UI in a branch in CVS.  That's not done, but the more braindead
   mistakes really ought to be fixed, and should have been back in May when
   I found them...

* Aptitude can now generate a simple logfile when doing a dpkg run
   (and optionally pipe it into a command)  It's not much (it should really
   be sorted, or at least include more info), but it can help with "err, what
   were those 500 packages I just upgraded?" situations :-)

* Column-formatting uses printf-style %-escapes instead of the old
   method.

* Fixes the "DOH, lockfiles don't go in /" bug.

* file: URLs (ie, local package repositories) now work.

[2000-04-18]
Version 0.0.7
  * The segfault that plagued 0.0.6.9 seems to be gone.  Thanks go to
   Panu Hällfors <panupa@iki.fi> for helping me narrow the problem down.
   Please let me know if you encounter similar problems (or, indeed, any
   problems :) ).

The following changes were in 0.0.6.9 but not mentioned (oops):

* Wrote a proper help screen, so you don't get the full README when you press
   '?'.  We still don't have a mechanism for dynamically adjusting the display
   based on keybindings, but this should make things somewhat nicer for
   newbies.

[2000-04-09]
Version 0.0.6.9
  *  This version introduces undo capabilities.  You can undo any number of
    actions on packages (install, remove, etc--even "forget new")  See the
    manual for details.

*  As a result, there are now two ways to quit: "q" quits and saves changes,
    and "x" quits and discards changes.

*  Major restructuring of the directory tree.  The toplevel now contains only
    code for aptitude itself--low-level UI stuff is in vscreen/ and generic
    useful routines (eg, the apt-cache wrapper) are in generic/

*  Major changes to the keybinding code; keybindings are now mostly shared
    between the different contexts they occur in, with the ability to override
    a keybinding in a particular context.

*  Added some alternative keybindings (vi-style and others), by popular
    request.

*  Reorganized the TODO list and added a bunch of stuff to it.

*  Searching now handles virtual packages

*  Limiting on package names no longer segfaults

*  Columns with nothing to display should display a placeholder value
    (eg, "<none>") instead of simply being blank.

*  Fixed various problems with detecting and flagging broken dependencies

*  Fixed various problems with the handling and displaying of OR groups

*  Reverse dependencies which occur because of Provides are now displayed
    correctly.

*  There is no longer a default binding for just displaying a package's
    description; "i" will display the full information screen by default.
    (it's just as easy to see the description this way, and you get more
     information as well)  The old behavior can be regained by binding
    Description to "i": 'Aptitude::UI::Keybindings::Description "i";' in
    /etc/apt/apt.conf  (you may need to remove the binding for InfoScreen
    as well)

*  Various segfaults when trying to get information about virtual packages
    were fixed.

*  You can now perform a package-list update or an install run from any apt
    tree, not just a package list (or at least you should be able to)  Of course,
    if the package you are viewing vanishes from the cache as a result, you will
    be sent back to where you came from.

*  Added a match type, ~c, which matches removed packages with conffiles
    remaining on the system.

*  You can now easily toggle the display of column headers at runtime by
    pressing "h".

[2000-02-06]
Version 0.0.6a
  *  Fixed a rather embarassing compile error that got into 0.0.6.

[2000-02-06]
Version 0.0.6
  *  Greatly improved search capabilities.  You can now match on many different
    attributes of a package, and combine search terms into complex expressions.
    This is used both for searching and implementing "display limits", which
    act as a filter for the visible list of packages.  See README for details.

*  Added commands to expand and collapse an entire tree of packages.

*  Searches now have a 'wraparound' behavior.

*  Actually set up a binding for Refresh, handle it globally.

*  Made the display of broken packages more uniform.

*  Fixed a problem that caused packages to be put on hold when you cancelled
    a removal or an install.

*  Pressing "hold" on a package which can't be upgraded now /toggles/ the
    sticky-hold state (it was hard to turn it off previously)

*  Fixed another dependency-OR handling bug which caused OR lists to appear
    to include the first package before the list.

*  Changed the install-preview screen to more correctly packages whose state
    was changed by fixing broken dependencies.  Packages which are being
    installed or deleted for this reason get their own trees.

*  The amount of padding after a column can now vary by column and is
    configurable.

*  Errors now use a single color definition, and are white on red.

*  You can now download and view the Changelog for a package (not perfect
    yet: you get HTML cruft, not all packages work (that I may not be able
    to fix) )

*  Fixed a bug which caused problems with displaying errors.

*  Added column types for the section and priority.

*  Added a minimal online-help system (just displays the README)

*  Internal change (not used yet): the vscreen main loop now supports the
    registration of timers.  (configure with --with-periodic-beep to
    enable a really annoying beep at one-second intervals)

*  Internal change: the status/header-lines and status widget handling of
    vs_tree were split into a new class, vs_minibuf_win.

*  Internal change: vscreen::repaint no longer implicitly calls refresh.

*  Internal change: the code to orchestrate downloads moved to
    download.{cc,h}

[2000-01-19]
Version 0.0.5
  *  This release has a lot of bugfixes, column formatting support, and a
    greatly fixed status-line editor.

*  Sanitized and made consistent a lot of arbitrary decisions about what
    version to use when looking statistics up about a package.  The function
    pkg_item::visible_version() handles this.

*  You can now get package information by pressing Enter while a particular
    version of a package is selected.  Information about that version will
    be displayed.

*  Don't crash if the user tries to update the package lists while not root
    or while another apt is running.  (oops..)

*  The preview screen *should* separate out packages which can't be upgraded
    because of broken dependencies.

*  Broken versions weren't being displayed with a "broken" color; fixed.

*  Throttle the update frequency of the progress bars; previously I was
    updating as quickly as possible, which lead to a massive loading up of the
    system.  This change greatly improved startup times.

*  libncurses5 sometimes sends KEY_RESIZEs -- don't assert their absence
    anymore, just ignore them :)

*  column support!  Configurable!  This is really the major feature in this
    release; see the README for more

*  Overhauled the status-line editing widget to fix a lot of small bugs and
    greatly improve editing.

*  Added a single keystroke to repeat the last search (bind something to
    ReSearch)

*  At the request of omega@anomie.dhis.net, added a status tree for obsolete
    packages.

[2000-01-10]
Version 0.0.4a
  *  "Faster than a speeding bullet" release.  (I really am starting to regret
    trying to come up with clever names for releases. :) )

*  Had a sudden flash of inspiration and added the three-line fix needed to
    hack around libncurses5's leaveok() brokenness.

[2000-01-10]
Version 0.0.4
  *  "New Year's Resolution" release.  I actually managed to fix everything
    which I claimed I would, but I've resolved never to promise to fix
    something in the next release again.  Even to myself. ;-)  Also, I want
    to release versions more often..

*  Aptitude now tries to Do The Right Thing with regard to the dselect
    state of a package by adjusting its own state when the dselect state
    changes in between runs.  This prevents the really bad problems I
    experienced.

*  The interface coloration is now configurable (see README for details)

*  More information is available in the download screen -- the actual amount
    of data dowloaded for each item and an estimated time to completion (for
    everything) are displayed.

*  Compiles against libncurses5, although there's an annoying visual bug when
    using libncurses5 that I can't get rid of (leaveok doesn't seem to hide
    the cursor anymore..)

*  Fixed the bug which caused ORs in dependencies to apparently continue
    forever (that is, "Depends: libc6, mutt | mail-reader, libncurses4" would
    be displayed as "Depends: libc6, mutt | mail-reader | libncurses4")

*  Rewrote the various messages and interaction involving the status line
    to be done the Right Way[tm].

*  Aptitude now (by default) displays what changes will be made -- that
    is, which packages will be installed, removed, etc, before
    performing a package run -- press the "install packages" key again to
    continue.

*  Setting Aptitude::Auto-Install to true will cause dependencies of a
    package to automatically be marked for installation when you select it to
    be installed.

*  Aptitude now (by default) attempts to resolve missing dependencies and
    fix broken packages before doing an install run.  To disable this, set
    "Aptitude::Fix-Broken" to false.

*  A screen with all information about the package collected into one
    location is now available (by default, you can access it by pressing
    Enter while a package is selected)

*  Finally got rid of the visual bug that caused non-selectable things to
    appear selected (I fixed it by not displaying them as selected even when
    they are ;-) )

*  Added descriptive headers to the version and dependency lists.

*  Made the behavior of selections around non-selectable items much more
    logical.

*  Package trees now display, in the header, an estimate of the number of
    bytes which will be downloaded and installed on the next package run.

*  Packages can now be reinstalled.

*  Removed a lot of the old test code.  The next release will probably (see
    my resolution :) ) rename "testscr.cc" to "main.cc".

*  Documentation updates.  Rewrote aptitude-hackers-guide.txt to be less a
    file-by-file tour and more a high-level overview.

*  Included a real CVS commit log (see ChangeLog)

[1999-12-20]
Version 0.0.3
  *  "Merry Christmas and a Happy Armageddon" release.  This'll probably be the
    last Aptitude release before the year 2000.  Assuming that civilization has
    not collapsed, expect to see another version early in the new year.
    (hopefully before potato freezes ;-) )  If not, I guess I'll have to start
    porting it to the abacus platform..

*  Configurable keybindings!  Rejoice!  See README for more info and
    examples.

*  aptitude now has persistent state, stored (by default) in
    /var/state/aptitude.

*  This is used to implement some dselect-like capabilities, including
    'sticky' selections that persist across sessions and the ability to track
    new packages.  New packages are implemented in a manner entirely orthogonal
    to selection state, which means (in short words) that a package can
    remain "new" for an indefinite amount of time, even after it's installed.

*  Two configuration options, Aptitude::Forget-New-On-Update and
    Aptitude::Forget-New-On-Install, are provided to automatically clear the
    list of new packages.

*  As an unforunate side-effect, dselect selections are no longer inherited.
    The main reason is that I couldn't think of a clean way to save the
    package states into the dselect database (calling dpkg --set-selections
    should work, but you have to play with lockfiles then..)  And it's tricky
    in general to try to manage two almost-but-not-quite identical databases
    of info.
     This may come back in the next release if I can work out how to do it
    (but it'll probably be controlled by a flag and off by default)  On the
    other hand, it's not really needed unless you're trying to mix dselect
    and aptitude.

*  The package list can be searched.  This occasioned at least one really
    nasty (but non-buggy!) hack, which I'll fix in the next release.  Currently
    *only* package lists (not version lists, etc) can be meaningfully searched,
    and searching only looks for substrings in the package name -- no
    regexps or checking of descriptions. (guess when this'll be fixed?)

*  A progress bar is now available for initialization and so on

*  Errors are displayed by the UI (needs a little work still, but
    functional..)

*  An annoying resize bug in 0.0.2 was fixed -- if you resized the xterm
    during a download, everything would start to flicker.

*  Various segfaults, crashes, hangs, and visual quirks were eliminated.

*  This is the first release to get a tag in CVS! :)

[1999-12-05]
Version 0.0.2
  * aptitude can now download and install packages!  This means that it's
   now technically possible to use it in place of other package management
   tools, although it's still lacking some stuff that would make it a really
   useful program.  This is the major change, and the reason for the new
   release.
  * dselect selections are now inherited
  * short package descriptions are displayed in the status line of the package
   tree
  * you can mark package *versions* for installation and removal (sometimes)
  * broken dependencies should be visually flagged
  * Various other bugfixes and tweaks.

[1999-11-18]
Version 0.0.1  --  Very preliminary alpha version released for comment and/or
                   criticism.

[1999-10-20]
Version 0.0.0  --  Added automake support, it requires this file.
                   Nothing else to say, I don't have enough code to make
		   this file useful yet.
