          packages to worker that causes the situation that some of
          automatically installed packages are not marked as such. If you
          installed something big with 0.6.{0-2} libcupt-perl versions, you
          will need to go and mark needed packages as automatically installed
          manually (e.g. using 'cupt markauto'). Sorry for the inconvenience.

  * Cupt:
    - Cache:
      - Package:

          mandate it.
      - SourceVersion, BinaryVersion:

          mutator methods (fields). Documented all fields.
        - Don't choke if 'Section' field is not defined.
        - [API break] The field 'avail_as' has been renamed to 'available_as'.

          including "essentialness" of the version.
        - Fixed a crash when performing a deep search for versions that have
          other than original version have, but still satisfiable
          pre-dependency relation expression.
        - Check Recommends/Suggests only when all hard dependencies are
          satisfied.
        - Resolver doesn't unconditionally pre-install Recommends and/or
          Suggests of manually installed/upgraded/downgraded packages
          (if 'apt::install-recommends' and 'apt::install-suggests' turned on,
          respectively) anymore. This change has two main consequences:
          + The common pinning/resolver rules are now applied to
            Recommends/Suggests of manually specified packages too. Besides of
            grown inner flexibility, you can now pin out specific packages or
            versions you don't like.
          + If you upgrade/downgrade the package which has unsatisfied
            Recommends/Suggests and the old and new version of the package
            has the same relation expression, resolver won't try to change
            anything.

          (directly or indirectly) on appropriate 'configure' one.
        - Detect the packages that break Pre-Depends in inavoidable way, list
          them and exit with an error.
        - Fixed a crash while re-checking hash sums of existing archives
          (introduced after 0.5.2). Thanks to Cyril Brulebois.

          uncompressing.
        - 'update_release_and_index_data': remove the downloaded Release.gpg if
          signature verification failed and 'cupt::update::keep-bad-signatures'
          is false (this is the default setting) for the compatibility with APT.
          Thanks to Goswin von Brederlow <goswin-v-b@web.de>.
          (Closes: #533753). Urgency is set to 'medium' because of this fix.
        - 'update_release_and_index_data': download index file even if
          signature download/check failed.
      - Resolvers/Native:
        - Reworked solution rank system.
        - Dropped 'first-good' solution chooser. It can be mimicked by setting
          'max-solution-count' option to 1.
        - Run cleaning auto-installed packages also before resolving, aiming
          to reduce number of solutions resolver should work with.
        - Made "zero" line for actions 400 points less, affecting ordering
          solutions for processing for default 'fair' resolver type. Leads to
          significant (several times) speed-up for some cases. Makes possible
          to obtain at least one solution for some hard queries (like removing
          core system components).

          by 'satisfy' query.
    - Download:

        - Worker thread: pass correct URI to download progress in case of
          ACKed download.
        - 'download' method: switched to modern interface of File::Temp,
          getting rid of compatibility one.
        - 'download' method: use POSIX::mkfifo instead of calling 'mkfifo'
          program.

cupt (0.1.4) unstable; urgency=low

  * cupt:
    - 'policy' subcommand:

    - Fixed skipping option-like arguments when searching for a command.
    - Implemented option '--show-reasons' for management actions.
    - New 'copyright' subcommand, similar to 'changelog' subcommand. Currently
      implemented only for installed packages and official Debian and Ubuntu
      repositories.
    - 'changelog', 'copyright' subcommands: work around dropping an epoch from
      version strings in links to Debian/Ubuntu pages.
    - The option '--install-unpacked' went away in favor of new
      '--no-install-unpacked' one, installing unpacked packages is now the
      default.
  * Cupt:
    - System:
      - Resolver:
        - Fixed erroneous autovivification of package entries which are not
          installed when checking for sticks of candidate versions than can
          satisfy forward dependencies.
        - Fixed wrong sharing 'fake satisfied' entries between package entries
          in different solution branches.
        - Honor 'cupt::resolver::track-reasons' configuration option.
      - Worker:
        - APT mangles ':' chars in names of deb archives. Cupt doesn't do the
          same. So, to pick up debs downloaded by libapt, worker now generates
          symlinks from 'right' names to 'mangled' names whenever possible.
        - Moved downloading stage to start of 'do_actions' method.
        - Reverted "Don't introduce action loops when uniting 'remove' and
          'unpack' actions".
        - Instead, tried to drop extraneous action interdepedencies by using and
          checking saved relation info and merging 'unpack' with 'configure'.
        - And, since unconditional merging 'unpack' with 'configure' can
          introduce another dependency loops, perform merge only if the
          operation can "eat" some dependencies.
        - In case some package have only 'configure' action without 'unpack',
          check for conflicts too in a straightforward way.
        - In the series of heterogeneous actions pass '--force-conflicts' to
          the '--unpack' and '--install'.
        - Generate stdin version 2 for the 'dpkg::pre-install-pkgs' hook for
          all hooks declared, not only for apt-listchanges.
        - Implemented the installs, downgrades and removes for the stdin
          version 2 for the 'dpkg::pre-install-pkgs' hook.
    - Config:
      - New configuration option 'cupt::resolver::track-reasons'.

          had the download been processed before or not, and 'download' won't
          run post-action for already processed downloads; this change should
          avoid future race conditions when the multiple downloads of the same
          file with enabled postprocessing were scheduled.
        - Worker thread and 'download' method: delay sending result to
          download progress before 'download' acked the result
          (i.e. run post-check for it).
      - Method:

        - Road all progress requests through own pipe, not directly.
        - Update progress meter several times during a second.
        - Made more strings translatable.
      - Progress:
        - New method 'get_start_time'.
        - New method 'get_long_alias_for_uri'.
        - New method 'get_short_alias_for_uri'.
        - [API break] The control and flow logic was moved from
          Progresses/Console to 'progress' method.
        - New method 'hook' for subclasses.
        - New method 'get_overall_download_progress'.
        - New accessor/mutator 'download_entries'.
        - New method 'get_download_speed'.
        - New class-wide parameter variable 'o_download_speed_accuracy';
        - Various documentation improvements.
      - Progresses/Console:
        - Substituted obsoleted 'progress' method with new 'hook' method.
        - Fixed dangling, wrong-placed console cursor.
        - Also output download speed.
        - Output count of downloaded bytes for each package in
          human-readable form too (in addition to all size bytes count for
          package). In four words, "10829837/15.9MiB" -> '10.1MiB/15.9MiB'.
    - System:
      - Worker:
        - Honor 'cupt::worker::download-only' option.
        - Added 'debug::worker' config option to print some debug info.
        - Bump Pre-Depends requirements to 'configure' to make sure to not
          violate Debian Policy.
        - Merge all 'unpack' + 'configure' actions into 'install' action
          unconditionally.
        - Don't create fake 'remove' actions, just use existing 'install'
          ones instead. This should resolve problems with scheduling
          upgrading packages containing 'Pre-Depends'.
        - Made all inter-action relations unversioned, this should ensure that
          all 'install' -> 'remove' and 'remove' -> 'install' dependencies are
          not underestimated.
        - Ensure that download manager is destroyed before processing the
          result of downloads.
    - Config:
      - New option 'cupt::worker::download-only', defaults to false.
      - Use value of 'dir::bin::dpkg', not plain 'dpkg' to obtain
        archirecture.
      - The option 'gpgv::trustedkeyring' now defaults to
        '/var/lib/cupt/trusted.gpg'.
    - Cache:
      - Introduce the hack to copy APT's trusted keyring whenever possible to
        cupt's keyring place. It will be removed once key update mechanism
        would be implemented.
      - When checking signatures, generate proper error message if the keyring
        file doesn't exist.
      - Relation:
        - New free subroutine 'parse_relation_line' for parsing relation
          sequences.
  * debian/libcupt-perl.postinst:
    - Don't mess with /etc/apt/trusted.gpg for now. Instead copy it to cupt's
      own keyring place.
  * debian/libcupt-perl.prerm:
    - Introduced to clean up /var/lib/cupt directory.
