Update to 0.91:

bzr 0.91 2007-09-26
===================

  BUG FIXES

bzr 0.91rc2 2007-09-11
======================

   * Replaced incorrect tarball for previous release; a debug statement was left
     in bzrlib/remote.py.

bzr 0.91rc1 2007-09-11
======================

  CHANGES:

   * The default branch and repository format has changed to
     ``dirstate-tags``, so tag commands are active by default.
     This format is compatible with Bazaar 0.15 and later.
     This incidentally fixes bug #126141.
     (Martin Pool)

   * ``--quiet`` or ``-q`` is no longer a global option. If present, it
     must now appear after the command name. Scripts doing things like
     ``bzr -q missing`` need to be rewritten as ``bzr missing -q``.
     (Ian Clatworthy)

  FEATURES:

   * New option ``--author`` in ``bzr commit`` to specify the author of the
     change, if it's different from the committer. ``bzr log`` and
     ``bzr annotate`` display the author instead of the committer.
     (Lukáš Lalinský)

   * In addition to global options and command specific options, a set of
     standard options are now supported. Standard options are legal for
     all commands. The initial set of standard options are:

     * ``--help`` or ``-h`` - display help message
     * ``--verbose`` or ``-v`` - display additional information
     * ``--quiet``  or ``-q`` - only output warnings and errors.

     Unlike global options, standard options can be used in aliases and
     may have command-specific help. (Ian Clatworthy)

   * Verbosity level processing has now been unified. If ``--verbose``
     or ``-v`` is specified on the command line multiple times, the
     verbosity level is made positive the first time then increased.
     If ``--quiet`` or ``-q`` is specified on the command line
     multiple times, the verbosity level is made negative the first
     time then decreased. To get the default verbosity level of zero,
     either specify none of the above , ``--no-verbose`` or ``--no-quiet``.
     Note that most commands currently ignore the magnitude of the
     verbosity level but do respect *quiet vs normal vs verbose* when
     generating output. (Ian Clatworthy)

   * ``Branch.hooks`` now supports ``pre_commit`` hook. The hook's signature
     is documented in BranchHooks constructor. (Nam T. Nguyen, #102747)

  BUG FIXES

  IMPROVEMENTS:

   * Add the option "--show-diff" to the commit command in order to display
     the diff during the commit log creation. (Goffredo Baroncelli)

   * ``pull`` and ``merge`` are much faster at installing bundle format 4.
     (Aaron Bentley)

   * ``pull -v`` no longer includes deltas, making it much faster.
     (Aaron Bentley)

   * ``send`` now sends the directive as an attachment by default.
     (Aaron Bentley, Lukáš Lalinský, Alexander Belchenko)

   * Documentation updates (Martin Albisetti)

   * Help on debug flags is now included in ``help global-options``.
     (Daniel Watkins, #124853)

   * Parameters passed on the command line are checked to ensure they are
     supported by the encoding in use. (Daniel Watkins)

   * The compression used within the bzr repository has changed from zlib
     level 9 to the zlib default level. This improves commit performance with
     only a small increase in space used (and in some cases a reduction in
     space). (Robert Collins)

   * Initial commit no longer SHAs files twice and now reuses the path
     rather than looking it up again, making it faster.
     (Ian Clatworthy)

   * New option ``-c``/``--change`` for ``diff`` and ``status`` to show
     changes in one revision.  (Lukáš Lalinský)

   * If versioned files match a given ignore pattern, a warning is now
     given. (Daniel Watkins, #48623)

   * ``bzr status`` now has -S as a short name for --short and -V as a
     short name for --versioned. These have been added to assist users
     migrating from Subversion: ``bzr status -SV`` is now like
     ``svn status -q``.  (Daniel Watkins, #115990)

   * Added C implementation of  ``PatienceSequenceMatcher``, which is about
     10x faster than the Python version. This speeds up commands that
     need file diffing, such as ``bzr commit`` or ``bzr diff``.
     (Lukáš Lalinský)

   * HACKING has been extended with a large section on core developer tasks.
     (Ian Clatworthy)

   * Add ``branches`` and ``standalone-trees`` as online help topics and
     include them as Concepts within the User Reference.
     (Paul Moore, Ian Clatworthy)

  API BREAKS:

   * ``Branch.append_revision`` is removed altogether; please use
     ``Branch.set_last_revision_info`` instead.  (Martin Pool)

   * CommitBuilder now advertises itself as requiring the root entry to be
     supplied. This only affects foreign repository implementations which reuse
     CommitBuilder directly and have changed record_entry_contents to require
     that the root not be supplied. This should be precisely zero plugins
     affected. (Robert Collins)

   * The ``add_lines`` methods on ``VersionedFile`` implementations has changed
     its return value to include the sha1 and length of the inserted text. This
     allows the avoidance of double-sha1 calculations during commit.
     (Robert Collins)

   * ``Transport.should_cache`` has been removed.  It was not called in the
     previous release.  (Martin Pool)

  TESTING:

   * Tests may now raise TestNotApplicable to indicate they shouldn't be
     run in a particular scenario.  (Martin Pool)

   * New function multiply_tests_from_modules to give a simpler interface
     to test parameterization.  (Martin Pool, Robert Collins)

   * ``Transport.should_cache`` has been removed.  It was not called in the
     previous release.  (Martin Pool)

   * NULL_REVISION is returned to indicate the null revision, not None.
     (Aaron Bentley)

   * Use UTF-8 encoded StringIO for log tests to avoid failures on
     non-ASCII committer names.  (Lukáš Lalinský)

bzr 0.90 2007-08-28
===================

  IMPROVEMENTS:

    * Documentation is now organized into multiple directories with a level
      added for different languages or locales. Added the Mini Tutorial
      and Quick Start Summary (en) documents from the Wiki, improving the
      content and readability of the former. Formatted NEWS as Release Notes
      complete with a Table of Conents, one heading per release. Moved the
      Developer Guide into the main document catalog and provided a link
      from the developer document catalog back to the main one.
      (Ian Clatworthy, Sabin Iacob, Alexander Belchenko)

  API CHANGES:

    * The static convenience method ``BzrDir.create_repository``
      is deprecated.  Callers should instead create a ``BzrDir`` instance
      and call ``create_repository`` on that.  (Martin Pool)

bzr 0.90rc1 2007-08-14
======================

  BUGFIXES:

    * ``bzr init`` should connect to the remote location one time only.  We
      have been connecting several times because we forget to pass around the
      Transport object. This modifies ``BzrDir.create_branch_convenience``,
      so that we can give it the Transport we already have.
      (John Arbash Meinel, Vincent Ladeuil, #111702)

    * Get rid of sftp connection cache (get rid of the FTP one too).
      (Vincent Ladeuil, #43731)

    * bzr branch {local|remote} remote don't try to create a working tree
      anymore.
      (Vincent Ladeuil, #112173)

    * All identified multiple connections for a single bzr command have been
      fixed. See bzrlib/tests/commands directory.
      (Vincent Ladeuil)

    * ``bzr rm`` now does not insist on ``--force`` to delete files that
      have been renamed but not otherwise modified.  (Marius Kruger,
      #111664)

    * ``bzr selftest --bench`` no longer emits deprecation warnings
      (Lukáš Lalinský)

    * ``bzr status`` now honours FILE parameters for conflict lists
      (Aaron Bentley, #127606)

    * ``bzr checkout`` now honours -r when reconstituting a working tree.
      It also honours -r 0.  (Aaron Bentley, #127708)

    * ``bzr add *`` no more fails on Windows if working tree contains
      non-ascii file names. (Kuno Meyer, #127361)

    * allow ``easy_install bzr`` runs without fatal errors.
      (Alexander Belchenko, #125521)

    * Graph._filter_candidate_lca does not raise KeyError if a candidate
      is eliminated just before it would normally be examined.  (Aaron Bentley)

    * SMTP connection failures produce a nice message, not a traceback.
      (Aaron Bentley)

  IMPROVEMENTS:

    * Don't show "dots" progress indicators when run \ 
non-interactively, such
      as from cron.  (Martin Pool)

    * ``info`` now formats locations more nicely and lists "submit" and
      "public" branches (Aaron Bentley)

    * New ``pack`` command that will trigger database compression within
      the repository (Robert Collins)

    * Implement ``_KnitIndex._load_data`` in a pyrex extension. The pyrex
      version is approximately 2-3x faster at parsing a ``.kndx`` file.
      Which yields a measurable improvement for commands which have to
      read from the repository, such as a 1s => 0.75s improvement in
      ``bzr diff`` when there are changes to be shown.  (John Arbash Meinel)

    * Merge is now faster.  Depending on the scenario, it can be more than 2x
      faster. (Aaron Bentley)

    * Give a clearer warning, and allow ``python setup.py install`` to
      succeed even if pyrex is not available.
      (John Arbash Meinel)

    * ``DirState._read_dirblocks`` now has an optional Pyrex
      implementation. This improves the speed of any command that has to
      read the entire DirState. (``diff``, ``status``, etc, improve by
      about 10%).
      ``bisect_dirblocks`` has also been improved, which helps all
      ``_get_entry`` type calls (whenever we are searching for a
      particular entry in the in-memory DirState).
      (John Arbash Meinel)

    * ``bzr pull`` and ``bzr push`` no longer do a complete walk of the
      branch revision history for ui display unless -v is supplied.
      (Robert Collins)

    * ``bzr log -rA..B`` output shifted to the left margin if the log only
      contains merge revisions. (Kent Gibson)

    * The ``plugins`` command is now public with improved help.
      (Ian Clatworthy)

    * New bundle and merge directive formats are faster to generate, and

    * Annotate merge now works when there are local changes. (Aaron Bentley)

    * Commit now only shows the progress in terms of directories instead of
      entries. (Ian Clatworthy)

    * Fix ``KnitRepository.get_revision_graph`` to not request the graph 2
      times. This makes ``get_revision_graph`` 2x faster. (John Arbash
      Meinel)

    * Fix ``VersionedFile.get_graph()`` to avoid using
      ``set.difference_update(other)``, which has bad scaling when
      ``other`` is large. This improves ``VF.get_graph([version_id])`` for
      a 12.5k graph from 2.9s down to 200ms. (John Arbash Meinel)

    * The ``--lsprof-file`` option now generates output for KCacheGrind if
      the file starts with ``callgrind.out``. This matches the default file
      filtering done by KCacheGrind's Open Dialog. (Ian Clatworthy)

    * Fix ``bzr update`` to avoid an unnecessary
      ``branch.get_master_branch`` call, which avoids 1 extra connection
      to the remote server. (Partial fix for #128076, John Arbash Meinel)

    * Log errors from the smart server in the trace file, to make debugging
      test failures (and live failures!) easier.  (Andrew Bennetts)

    * The HTML version of the man page has been superceded by a more
      comprehensive manual called the Bazaar User Reference. This manual
      is completed generated from the online help topics. As part of this
      change, limited reStructuredText is now explicitly supported in help
      topics and command help with 'unnatural' markup being removed prior
      to display by the online help or inclusion in the man page.
      (Ian Clatworthy)

    * HTML documentation now use files extension ``*.html``
      (Alexander Belchenko)

    * The cache of ignore definitions is now cleared in WorkingTree.unlock()
      so that changes to .bzrignore aren't missed. (#129694, Daniel Watkins)

    * ``bzr selftest --strict`` fails if there are any missing features or
      expected test failures. (Daniel Watkins, #111914)

    * Link to registration survey added to README. (Ian Clatworthy)

    * Windows standalone installer show link to registration survey
      when installation finished. (Alexander Belchenko)

  LIBRARY API BREAKS:

    * Deprecated dictionary ``bzrlib.option.SHORT_OPTIONS`` removed.
      Options are now required to provide a help string and it must
      comply with the style guide by being one or more sentences with an
      initial capital and final period. (Martin Pool)

    * KnitIndex.get_parents now returns tuples. (Robert Collins)

    * Ancient unused ``Repository.text_store`` attribute has been removed.
      (Robert Collins)

    * The ``bzrlib.pack`` interface has changed to use tuples of bytestrings
      rather than just bytestrings, making it easier to represent multiple
      element names. As this interface was not used by any internal facilities
      since it was introduced in 0.18 no API compatibility is being preserved.
      The serialised form of these packs is identical with 0.18 when a single
      element tuple is in use. (Robert Collins)

  TESTING:

    * Remove selftest ``--clean-output``, ``--numbered-dirs`` and
      ``--keep-output`` options, which are obsolete now that tests
      are done within directories in $TMPDIR.  (Martin Pool)

    * The SSH_AUTH_SOCK environment variable is now reset to avoid
      interaction with any running ssh agents.  (Jelmer Vernooij, #125955)

    * run_bzr_subprocess handles parameters the same way as run_bzr:
      either a string or a list of strings should be passed as the first
      parameter.  Varargs-style parameters are deprecated. (Aaron Bentley)

Log message:
Modify the COMMENT so that seraches for "bazaar" should hit this package,
as well as "bzr".

Clean up some lint.

  BUGFIXES

bzr 0.18rc1  2007-07-10

  BUGFIXES

  IMPROVEMENTS:

    * The --lsprof-file option now dumps a text rendering of the profiling
      information if the filename ends in ".txt". It will also convert the
      profiling information to a format suitable for KCacheGrind if the
      output filename ends in ".callgrind". Fixes to the lsprofcalltree
      conversion process by Jean Paul Calderone and Itamar were also merged.
      See http://ddaa.net/blog/python/lsprof-calltree. (Ian Clatworthy)

    * ``info`` now defaults to non-verbose mode, displaying only paths and
      abbreviated format info.  ``info -v`` displays all the information
      formerly displayed by ``info``.  (Aaron Bentley, Adeodato Simó)

    * ``bzr missing`` now has better option names ``--this`` and ``--other``.
      (Elliot Murphy)

    * The internal ``weave-list`` command has become ``versionedfile-list``,
      and now lists knits as well as weaves.  (Aaron Bentley)

    * Automatic merge base selection uses a faster algorithm that chooses
      better bases in criss-cross merge situations (Aaron Bentley)

    * Progress reporting in ``commit`` has been improved. The various logical
      stages are now reported on as follows, namely:

      * Collecting changes [Entry x/y] - Stage n/m
      * Saving data locally - Stage n/m
      * Uploading data to master branch - Stage n/m
      * Updating the working tree - Stage n/m
      * Running post commit hooks - Stage n/m

      If there is no master branch, the 3rd stage is omitted and the total
      number of stages is adjusted accordingly.

      Each hook that is run after commit is listed with a name (as hooks
      can be slow it is useful feedback).
      (Ian Clatworthy, Robert Collins)

    * Various operations that are now faster due to avoiding unnecessary
      topological sorts. (Aaron Bentley)

    * Make merge directives robust against broken bundles. (Aaron Bentley)

    * The lsprof filename note is emitted via trace.note(), not standard
      output.  (Aaron Bentley)

    * ``bzrlib`` now exports explicit API compatibility information to assist
      library users and plugins. See the ``bzrlib.api`` module for details.
      (Robert Collins)

    * Remove unnecessary lock probes when acquiring a lockdir.
      (Martin Pool)

    * ``bzr --version`` now shows the location of the bzr log file, which
      is especially useful on Windows.  (Martin Pool)

    * -D now supports hooks to get debug tracing of hooks (though its currently
      minimal in nature). (Robert Collins)

    * Long log format reports deltas on merge revisions.
      (John Arbash Meinel, Kent Gibson)

    * Make initial push over ftp more resilient. (John Arbash Meinel)

    * Print a summary of changes for update just like pull does.
      (Daniel Watkins, #113990)

    * Add a -Dhpss option to trace smart protocol requests and responses.
      (Andrew Bennetts)

  BUGFIXES

bzr 0.17rc1  2007-06-12

  NOTES WHEN UPGRADING:

    * The kind() and is_executable() APIs on the WorkingTree interface no
      longer implicitly (read) locks and unlocks the tree. This *might*
      impact some plug-ins and tools using this part of the API. If you find
      an issue that may be caused by this change, please let us know,
      particularly the plug-in/tool maintainer. If encountered, the API
      fix is to surround kind() and is_executable() calls with lock_read()
      and unlock() like so::

        work_tree.lock_read()
        try:
            kind = work_tree.kind(...)
        finally:
            work_tree.unlock()

  IMPROVEMENTS:

    * There are two new help topics, working-trees and repositories that
      attempt to explain these concepts. (James Westby, John Arbash Meinel,
      Aaron Bentley)

    * Added ``bzr log --limit`` to report a limited number of revisions.
      (Kent Gibson, #3659)

    * Revert does not try to preserve file contents that were originally
      produced by reverting to a historical revision.  (Aaron Bentley)

    * ``bzr log --short`` now includes ``[merge]`` for revisions which
      have more than one parent. This is a small improvement to help
      understanding what changes have occurred
      (John Arbash Meinel, #83887)

    * TreeTransform avoids many renames when contructing large trees,
      improving speed.  3.25x speedups have been observed for construction of
      kernel-sized-trees, and checkouts are 1.28x faster.  (Aaron Bentley)

    * Commit on large trees is now faster. In my environment, a commit of
      a small change to the Mozilla tree (55k files) has dropped from
      66 seconds to 32 seconds. For a small tree of 600 files, commit of a
      small change is 33% faster. (Ian Clatworthy)

    * New --create-prefix option to bzr init, like for push.  (Daniel Watkins,
      #56322)

  BUGFIXES

bzr 0.16  2007-05-07

  BUGFIXES

  IMPROVEMENTS:

    * Move developer documentation to doc/developers/. This reduces clutter in
      the root of the source tree and allows HACKING to be split into multiple
      files. (Robert Collins, Alexander Belchenko)

    * Clean up the ``WorkingTree4._iter_changes()`` internal loops as well as
      ``DirState.update_entry()``. This optimizes the core logic for ``bzr
      diff`` and ``bzr status`` significantly improving the speed of
      both. (John Arbash Meinel)

bzr 0.16rc2  2007-04-30

  BUGFIXES

bzr 0.16rc1  2007-04-26

  NOTES WHEN UPGRADING:

    * ``bzr remove`` and ``bzr rm`` will now remove the working file, if
      it could be recovered again.
      This has been done for consistency with svn and the unix rm command.
      The old ``remove`` behaviour has been retained in the new option
      ``bzr remove --keep``, which will just stop versioning the file,
      but not delete it.
      ``bzr remove --force`` have been added which will always delete the
      files.
      ``bzr remove`` is also more verbose.
      (Marius Kruger, #82602)

  IMPROVEMENTS:

    * Merge directives can now be supplied as input to `merge` and `pull`,
      like bundles can.  (Aaron Bentley)

    * Sending the SIGQUIT signal to bzr, which can be done on Unix by
      pressing Control-Backslash, drops bzr into a debugger.  Type ``'c'``
      to continue.  This can be disabled by setting the environment variable
      ``BZR_SIGQUIT_PDB=0``.  (Martin Pool)

    * selftest now supports --list-only to list tests instead of running
      them. (Ian Clatworthy)

    * selftest now supports --exclude PATTERN (or -x PATTERN) to exclude
      tests with names that match that regular expression.
      (Ian Clatworthy, #102679)

    * selftest now supports --randomize SEED to run tests in a random order.
      SEED is typically the value 'now' meaning 'use the current time'.
      (Ian Clatworthy, #102686)

    * New option ``--fixes`` to commit, which stores bug fixing annotations as
      revision properties. Built-in support for Launchpad, Debian, Trac and
      Bugzilla bug trackers. (Jonathan Lange, James Henstridge, Robert Collins)

    * New API, ``bzrlib.bugtracker.tracker_registry``, for adding support for
      other bug trackers to ``fixes``. (Jonathan Lange, James Henstridge,
      Robert Collins)

    * ``selftest`` has new short options ``-f`` and ``-1``.  (Martin
      Pool)

    * ``bzrlib.tsort.MergeSorter`` optimizations. Change the inner loop
      into using local variables instead of going through ``self._var``.
      Improves the time to ``merge_sort`` a 10k revision graph by
      approximately 40% (~700->400ms).  (John Arbash Meinel)

    * ``make docs`` now creates a man page at ``man1/bzr.1`` fixing bug 107388.
      (Robert Collins)

    * ``bzr help`` now provides cross references to other help topics using
      the _see_also facility on command classes. Likewise the bzr_man
      documentation, and the bzr.1 man page also include this information.
      (Robert Collins)

    * Tags are now included in logs, that use the long log formatter.
      (Erik BÃ¥gfors, Alexander Belchenko)

    * ``bzr help`` provides a clearer message when a help topic cannot be
      found. (Robert Collins, #107656)

    * ``bzr help`` now accepts optional prefixes for command help. The help
      for all commands can now be found at ``bzr help commands/COMMANDNAME``
      as well as ``bzr help COMMANDNAME`` (which only works for commands
      where the name is not the same as a more general help topic).
      (Robert Collins)

    * ``bzr help PLUGINNAME`` will now return the module docstring from the
      plugin PLUGINNAME. (Robert Collins, #50408)

    * New help topic ``urlspec`` which lists the availables transports.
      (Goffredo Baroncelli)

    * doc/server.txt updated to document the default bzr:// port
      and also update the blurb about the hpss' current status.
      (Robert Collins, #107125).

    * ``bzr serve`` now listens on interface 0.0.0.0 by default, making it
      serve out to the local LAN (and anyone in the world that can reach the
      machine running ``bzr serve``. (Robert Collins, #98918)

    * A new smart server protocol version has been added.  It prefixes requests
      and responses with an explicit version identifier so that future protocol
      revisions can be dealt with gracefully.  (Andrew Bennetts, Robert Collins)

    * The bzr protocol version 2 indicates success or failure in every response
      without depending on particular commands encoding that consistently,
      allowing future client refactorings to be much more robust about error
      handling. (Robert Collins, Martin Pool, Andrew Bennetts)

    * The smart protocol over HTTP client has been changed to always post to the
      same ``.bzr/smart`` URL under the original location when it can.  This allows
      HTTP servers to only have to pass URLs ending in .bzr/smart to the smart
      server handler, and not arbitrary ``.bzr/*/smart`` URLs.  (Andrew Bennetts)

    * digest authentication is now supported for proxies and HTTP by the urllib
      based http implementation. Tested against Apache 2.0.55 and Squid
      2.6.5. Basic and digest authentication are handled coherently for HTTP
      and proxy: if the user is provided in the url (bzr command line for HTTP,
      proxy environment variables for proxies), the password is prompted for
      (only once). If the password is provided, it is taken into account. Once
      the first authentication is successful, all further authentication
      roundtrips are avoided by preventively setting the right authentication
      header(s).
      (Vincent Ladeuil).

  BUGFIXES

Log message:
update to bzr 0.15

bzr 0.15 2007-04-01

  BUGFIXES:

    * Handle incompatible repositories as a user issue when fetching.
      (Aaron Bentley)

    * Don't give a recommendation to upgrade when branching or
      checking out a branch that contains an old-format working tree.
      (Martin Pool)

bzr 0.15rc3  2007-03-26

  CHANGES:

    * A warning is now displayed when opening working trees in older
      formats, to encourage people to upgrade to WorkingTreeFormat4.
      (Martin Pool)

  IMPROVEMENTS:

    * HTTP redirections are now taken into account when a branch (or a
      bundle) is accessed for the first time. A message is issued at each
      redirection to inform the user. In the past, http redirections were
      silently followed for each request which significantly degraded the
      performances. The http redirections are not followed anymore by
      default, instead a RedirectRequested exception is raised. For bzrlib
      users needing to follow http redirections anyway,
      bzrlib.transport.do_catching_redirections provide an easy transition
      path.  (vila)

  INTERNALS:

    * Added ``ReadLock.temporary_write_lock()`` to allow upgrading an OS read
      lock to an OS write lock. Linux can do this without unlocking, Win32
      needs to unlock in between. (John Arbash Meinel)

    * New parameter ``recommend_upgrade`` to BzrDir.open_workingtree
      to silence (when false) warnings about opening old formats.
      (Martin Pool)

    * Fix minor performance regression with bzr-0.15 on pre-dirstate
      trees. (We were reading the working inventory too many times).
      (John Arbash Meinel)

  BUGFIXES:

    * Take smtp_server from user config into account.
      (vila, #92195)

    * Restore Unicode filename handling for versioned and unversioned files.
      (John Arbash Meinel, #92608)

    * Don't fail during ``bzr commit`` if a file is marked removed, and
      the containing directory is auto-removed.  (John Arbash Meinel, #93681)

    * ``bzr status FILENAME`` failed on Windows because of an uncommon
      errno. (``ERROR_DIRECTORY == 267 != ENOTDIR``).
      (Wouter van Heyst, John Arbash Meinel, #90819)

    * ``bzr checkout source`` should create a local branch in the same
      format as source. (John Arbash Meinel, #93854)

    * ``bzr commit`` with a kind change was failing to update the
      last-changed-revision for directories.  The
      InventoryDirectory._unchanged only looked at the parent_id and name,
      ignoring the fact that the kind could have changed, too.
      (John Arbash Meinel, #90111)

    * ``bzr mv dir/subdir other`` was incorrectly updating files inside
      the directory. So that there was a chance it would break commit,
      etc. (John Arbash Meinel, #94037)

    * Correctly handles mutiple permanent http redirections.
     (vila, #88780)

bzr 0.15rc2  2007-03-14

  NOTES WHEN UPGRADING:

    * Release 0.15rc2 of bzr changes the ``bzr init-repo`` command to
      default to ``--trees`` instead of ``--no-trees``.
      Existing shared repositories are not affected.

  IMPROVEMENTS:

    * New ``merge-directive`` command to generate machine- and human-readable
      merge requests.  (Aaron Bentley)

    * New ``submit:`` revision specifier makes it easy to diff against the
      common ancestor with the submit location (Aaron Bentley)

    * Added support for Putty's SSH implementation. (Dmitry Vasiliev)

    * Added ``bzr status --versioned`` to report only versioned files,
      not unknowns. (Kent Gibson)

    * Merge now autodetects the correct line-ending style for its conflict
      markers.  (Aaron Bentley)

  INTERNALS:

    * Refactored SSH vendor registration into SSHVendorManager class.
      (Dmitry Vasiliev)

  BUGFIXES:

    * New ``--numbered-dirs`` option to ``bzr selftest`` to use
      numbered dirs for TestCaseInTempDir. This is default behavior
      on Windows. Anyone can force named dirs on Windows
      with ``--no-numbered-dirs``. (Alexander Belchenko)

    * Fix ``RevisionSpec_revid`` to handle the Unicode strings passed in
      from the command line. (Marien Zwart, #90501)

    * Fix ``TreeTransform._iter_changes`` when both the source and
      destination are missing. (Aaron Bentley, #88842)

    * Fix commit of merges with symlinks in dirstate trees.
      (Marien Zwart)

    * Switch the ``bzr init-repo`` default from --no-trees to --trees.
      (Wouter van Heyst, #53483)

bzr 0.15rc1  2007-03-07

  SURPRISES:

    * The default disk format has changed. Please run 'bzr upgrade' in your
      working trees to upgrade. This new default is compatible for network
      operations, but not for local operations. That is, if you have two
      versions of bzr installed locally, after upgrading you can only use the
      bzr 0.15 version. This new default does not enable tags or nested-trees
      as they are incompatible with bzr versions before 0.15 over the network.

    * For users of bzrlib: Two major changes have been made to the working tree
      api in bzrlib. The first is that many methods and attributes, including
      the inventory attribute, are no longer valid for use until one of
      lock_read/lock_write/lock_tree_write has been called, and become invalid
      again after unlock is called. This has been done to improve performance
      and correctness as part of the dirstate development. (Robert Collins,
      John A Meinel, Martin Pool, and others).

    * For users of bzrlib: The attribute 'tree.inventory' should be considered
      readonly. Previously it was possible to directly alter this attribute, or
      its contents, and have the tree notice this. This has been made
      unsupported - it may work in some tree formats, but in the newer dirstate
      format such actions will have no effect and will be ignored, or even
      cause assertions. All operations possible can still be carried out by a
      combination of the tree API, and the bzrlib.transform API. (Robert
      Collins, John A Meinel, Martin Pool, and others).

  IMPROVEMENTS:

    * Support for OS Windows 98. Also .bzr.log on any windows system
      saved in My Documents folder. (Alexander Belchenko)

    * ``bzr mv`` enhanced to support already moved files.
      In the past the mv command would have failed if the source file doesn't
      exist. In this situation ``bzr mv`` would now detect that the file has
      already moved and update the repository accordingly, if the target file
      does exist.
      A new option ``--after`` has been added so that if two files already
      exist, you could notify Bazaar that you have moved a (versioned) file
      and replaced it with another. Thus in this case ``bzr move --after``
      will only update the Bazaar identifier.
      (Steffen Eichenberg, Marius Kruger)

    * ``ls`` now works on treeless branches and remote branches.
      (Aaron Bentley)

    * ``bzr help global-options`` describes the global options.
      (Aaron Bentley)

    * ``bzr pull --overwrite`` will now correctly overwrite checkouts.
      (Robert Collins)

    * Files are now allowed to change kind (e.g. from file to symlink).
      Supported by ``commit``, ``revert`` and ``status``
      (Aaron Bentley)

    * ``inventory`` and ``unknowns`` hidden in favour of ``ls``
      (Aaron Bentley)

    * ``bzr help checkouts`` descibes what checkouts are and some possible
      uses of them. (James Westby, Aaron Bentley)

    * A new ``-d`` option to push, pull and merge overrides the default
      directory.  (Martin Pool)

    * Branch format 6: smaller, and potentially faster than format 5.  Supports
      "append_history_only" mode, where the log view and revnos do not \ 
change,
      except by being added to.  Stores policy settings in
      ".bzr/branch/branch.conf".

    * append_only branches:  Format 6 branches may be configured so that log
      view and revnos are always consistent.  Either create the branch using
      "bzr init --append-revisions-only" or edit the config file as \ 
descriped
      in docs/configuration.txt.

    * rebind: Format 6 branches retain the last-used bind location, so if you
      "bzr unbind", you can "bzr bind" to bind to the \ 
previously-selected
      bind location.

    * Builtin tags support, created and deleted by the ``tag`` command and
      stored in the branch.  Tags can be accessed with the revisionspec
      ``-rtag:``, and listed with ``bzr tags``.  Tags are not versioned
      at present. Tags require a network incompatible upgrade. To perform this
      upgrade, run ``bzr upgrade --dirstate-tags`` in your branch and
      repositories. (Martin Pool)

    * The bzr:// transport now has a well-known port number, 4155, which it will
      use by default.  (Andrew Bennetts, Martin Pool)

    * Bazaar now looks for user-installed plugins before looking for site-wide
      plugins. (Jonathan Lange)

    * ``bzr resolve`` now detects and marks resolved text conflicts.
      (Aaron Bentley)

  INTERNALS:

    * Internally revision ids and file ids are now passed around as utf-8
      bytestrings, rather than treating them as Unicode strings. This has
      performance benefits for Knits, since we no longer need to decode the
      revision id for each line of content, nor for each entry in the index.
      This will also help with the future dirstate format.
      (John Arbash Meinel)

    * Reserved ids (any revision-id ending in a colon) are rejected by
      versionedfiles, repositories, branches, and working trees
      (Aaron Bentley)

    * Minor performance improvement by not creating a ProgressBar for
      every KnitIndex we create. (about 90ms for a bzr.dev tree)
      (John Arbash Meinel)

    * New easier to use Branch hooks facility. There are five initial hooks,
      all documented in bzrlib.branch.BranchHooks.__init__ - 'set_rh',
      'post_push', 'post_pull', 'post_commit', 'post_uncommit'. These hooks
      fire after the matching operation on a branch has taken place, and were
      originally added for the branchrss plugin. (Robert Collins)

    * New method ``Branch.push()`` which should be used when pushing from a
      branch as it makes performance and policy decisions to match the UI
      level command ``push``. (Robert Collins).

    * Add a new method ``Tree.revision_tree`` which allows access to cached
      trees for arbitrary revisions. This allows the in development dirstate
      tree format to provide access to the callers to cached copies of
      inventory data which are cheaper to access than inventories from the
      repository.
      (Robert Collins, Martin Pool)

    * New Branch.last_revision_info method, this is being done to allow
      optimization of requests for both the number of revisions and the last
      revision of a branch with smartservers and potentially future branch
      formats. (Wouter van Heyst, Robert Collins)

    * Allow 'import bzrlib.plugins.NAME' to work when the plugin NAME has not
      yet been loaded by load_plugins(). This allows plugins to depend on each
      other for code reuse without requiring users to perform file-renaming
      gymnastics. (Robert Collins)

    * New Repository method 'gather_stats' for statistic data collection.
      This is expected to grow to cover a number of related uses mainly
      related to bzr info. (Robert Collins)

    * Log formatters are now managed with a registry.
      ``log.register_formatter`` continues to work, but callers accessing
      the FORMATTERS dictionary directly will not.

    * Allow a start message to be passed to the ``edit_commit_message``
      function.  This will be placed in the message offered to the user
      for editing above the separator. It allows a template commit message
      to be used more easily. (James Westby)

    * ``GPGStrategy.sign()`` will now raise ``BzrBadParameterUnicode`` if
      you pass a Unicode string rather than an 8-bit string. Callers need
      to be updated to encode first. (John Arbash Meinel)

    * Branch.push, pull, merge now return Result objects with information
      about what happened, rather than a scattering of various methods.  These
      are also passed to the post hooks.  (Martin Pool)

    * File formats and architecture is in place for managing a forest of trees
      in bzr, and splitting up existing trees into smaller subtrees, and
      finally joining trees to make a larger tree. This is the first iteration
      of this support, and the user-facing aspects still require substantial
      work.  If you wish to experiment with it, use ``bzr upgrade
      --dirstate-with-subtree`` in your working trees and repositories.
      You can use the hidden commands ``split`` and ``join`` and to create
      and manipulate nested trees, but please consider using the nested-trees
      branch, which contains substantial UI improvements, instead.
      http://code.aaronbentley.com/bzr/bzrrepo/nested-trees/
      (Aaron Bentley, Martin Pool, Robert Collins).

  BUGFIXES:

    * ``bzr annotate`` now uses dotted revnos from the viewpoint of the
      branch, rather than the last changed revision of the file.
      (John Arbash Meinel, #82158)

    * Lock operations no longer hang if they encounter a permission problem.
      (Aaron Bentley)

    * ``bzr push`` can resume a push that was canceled before it finished.
      Also, it can push even if the target directory exists if you supply
      the ``--use-existing-dir`` flag.
      (John Arbash Meinel, #30576, #45504)

    * Fix http proxy authentication when user and an optional
      password appears in the ``*_proxy`` vars. (Vincent Ladeuil,
      #83954).

    * ``bzr log branch/file`` works for local treeless branches
      (Aaron Bentley, #84247)

    * Fix problem with UNC paths on Windows 98. (Alexander Belchenko, #84728)

    * Searching location of CA bundle for PyCurl in env variable (CURL_CA_BUNDLE),
      and on win32 along the PATH. (Alexander Belchenko, #82086)

    * ``bzr init`` works with unicode argument LOCATION.
      (Alexander Belchenko, #85599)

    * Raise DependencyNotPresent if pycurl do not support https. (Vincent
      Ladeuil, #85305)

    * Invalid proxy env variables should not cause a traceback.
      (Vincent Ladeuil, #87765)

    * Ignore patterns normalised to use '/' path separator.
      (Kent Gibson, #86451)

    * bzr rocks. It sure does! Fix case. (Vincent Ladeuil, #78026)

    * Fix bzrtools shelve command for removed lines beginning with "--"
      (Johan Dahlberg, #75577)

  TESTING:

    * New ``--first`` option to ``bzr selftest`` to run specified tests
      before the rest of the suite.  (Martin Pool)

Log message:
update to bzr-0.14

bzr 0.14  2007-01-23

  IMPROVEMENTS:

    * ``bzr help global-options`` describes the global options. (Aaron Bentley)

  BUG FIXES:

    * Skip documentation generation tests if the tools to do so are not
      available. Fixes running selftest for installled copies of bzr.
      (John Arbash Meinel, #80330)

    * Fix the code that discovers whether bzr is being run from it's
      working tree to handle the case when it isn't but the directory
      it is in is below a repository. (James Westby, #77306)

bzr 0.14rc1  2007-01-16

  IMPROVEMENTS:

    * New connection: ``bzr+http://`` which supports tunnelling the smart
      protocol over an HTTP connection. If writing is enabled on the bzr
      server, then you can write over the http connection.
      (Andrew Bennetts, John Arbash Meinel)

    * Aliases now support quotation marks, so they can contain whitespace
      (Marius Kruger)

    * PyCurlTransport now use a single curl object. By specifying explicitly
      the 'Range' header, we avoid the need to use two different curl objects
      (and two connections to the same server). (Vincent Ladeuil)

    * ``bzr commit`` does not prompt for a message until it is very likely to
      succeed.  (Aaron Bentley)

    * ``bzr conflicts`` now takes --text to list pathnames of text conflicts
      (Aaron Bentley)

    * Fix ``iter_lines_added_or_present_in_versions`` to use a set instead
      of a list while checking if a revision id was requested. Takes 10s
      off of the ``fileids_affected_by_revision_ids`` time, which is 10s
      of the ``bzr branch`` time. Also improve ``fileids_...`` time by
      filtering lines with a regex rather than multiple ``str.find()``
      calls. (saves another 300ms) (John Arbash Meinel)

    * Policy can be set for each configuration key. This allows keys to be
      inherited properly across configuration entries. For example, this
      should enable you to do::

        [/home/user/project]
        push_location = sftp://host/srv/project/
        push_location:policy = appendpath

      And then a branch like ``/home/user/project/mybranch`` should get an
      automatic push location of ``sftp://host/srv/project/mybranch``.
      (James Henstridge)

    * Added ``bzr status --short`` to make status report svn style flags
      for each file.  For example::

        $ bzr status --short
        A  foo
        A  bar
        D  baz
        ?  wooley

    * 'bzr selftest --clean-output' allows easily clean temporary tests
      directories without running tests. (Alexander Belchenko)

    * ``bzr help hidden-commands`` lists all hidden commands. (Aaron Bentley)

    * ``bzr merge`` now has an option ``--pull`` to fall back to pull if
      local is fully merged into remote. (Jan Hudec)

    * ``bzr help formats`` describes available directory formats. (Aaron Bentley)

  INTERNALS:

    * A few tweaks directly to ``fileids_affected_by_revision_ids`` to
      help speed up processing, as well allowing to extract unannotated
      lines. Between the two ``fileids_affected_by_revision_ids`` is
      improved by approx 10%. (John Arbash Meinel)

    * Change Revision serialization to only write out millisecond
      resolution. Rather than expecting floating point serialization to
      preserve more resolution than we need. (Henri Weichers, Martin Pool)

    * Test suite ends cleanly on Windows.  (Vincent Ladeuil)

    * When 'encoding_type' attribute of class Command is equal to 'exact',
      force sys.stdout to be a binary stream on Windows, and therefore
      keep exact line-endings (without LF -> CRLF conversion).
      (Alexander Belchenko)

    * Single-letter short options are no longer globally declared.  (Martin
      Pool)

    * Before using detected user/terminal encoding bzr should check
      that Python has corresponding codec. (Alexander Belchenko)

    * Formats for end-user selection are provided via a FormatRegistry (Aaron \ 
Bentley)

  BUG FIXES:

    * ``bzr missing --verbose`` was showing adds/removals in the wrong
      direction. (John Arbash Meinel)

    * ``bzr annotate`` now defaults to showing dotted revnos for merged
      revisions. It cuts them off at a depth of 12 characters, but you can
      supply ``--long`` to see the full number. You can also use
      ``--show-ids`` to display the original revision ids, rather than
      revision numbers and committer names. (John Arbash Meinel, #75637)

    * bzr now supports Win32 UNC path (e.g. \\HOST\path).
      (Alexander Belchenko, #57869)

    * Win32-specific: output of cat, bundle and diff commands don't mangle
      line-endings (Alexander Belchenko, #55276)

    * Replace broken fnmatch based ignore pattern matching with custom pattern
      matcher.
      (Kent Gibson, Jan Hudec #57637)

    * pycurl and urllib can detect short reads at different places. Update
      the test suite to test more cases. Also detect http error code 416
      which was raised for that specific bug. Also enhance the urllib
      robustness by detecting invalid ranges (and pycurl's one by detecting
      short reads during the initial GET). (Vincent Ladeuil, #73948)

    * The urllib connection sharing interacts badly with urllib2
      proxy setting (the connections didn't go thru the proxy
      anymore). Defining a proper ProxyHandler solves the
      problem.  (Vincent Ladeuil, #74759)

    * Use urlutils to generate relative URLs, not osutils
      (Aaron Bentley, #76229)

    * ``bzr status`` in a readonly directory should work without giving
      lots of errors. (John Arbash Meinel, #76299)

    * Mention the revisionspec topic for the revision option help.
      (Wouter van Heyst, #31663)

    * Allow plugins import from zip archives.
      (Alexander Belchenko, #68124)

Update to 0.13:

bzr 0.13  2006-12-05

  No changes from 0.13rc1

bzr 0.13rc1  2006-11-27

  IMPROVEMENTS:

    * New command ``bzr remove-tree`` allows the removal of the working
      tree from a branch.
      (Daniel Silverstone)

    * urllib uses shared keep-alive connections, so http
      operations are substantially faster.
      (Vincent Ladeuil, #53654)

    * ``bzr export`` allows an optional branch parameter, to export a bzr
      tree from some other url. For example:
      ``bzr export bzr.tar.gz http://bazaar-vcs.org/bzr/bzr.dev``
      (Daniel Silverstone)

    * Added ``bzr help topics`` to the bzr help system. This gives a
      location for general information, outside of a specific command.
      This includes updates for ``bzr help revisionspec`` the first topic
      included. (Goffredo Baroncelli, John Arbash Meinel, #42714)

    * WSGI-compatible HTTP smart server.  See ``doc/http_smart_server.txt``.
      (Andrew Bennetts)

    * Knit files will now cache full texts only when the size of the
      deltas is as large as the size of the fulltext. (Or after 200
      deltas, whichever comes first). This has the most benefit on large
      files with small changes, such as the inventory for a large project.
      (eg For a project with 2500 files, and 7500 revisions, it changes
      the size of inventory.knit from 11MB to 5.4MB) (John Arbash Meinel)

  BUG FIXES:

    * ``bzrlib/bzrdir.py`` was directly referencing ``bzrlib.workingtree``,
      without importing it. This prevented ``bzr upgrade`` from working
      unless a plugin already imported ``bzrlib.workingtree``
      (John Arbash Meinel, #70716)

    * Suppress the traceback on invalid URLs (Vincent Ladeuil, #70803).

    * Give nicer error message when an http server returns a 403
      error code. (Vincent Ladeuil, #57644).

    * When a multi-range http GET request fails, try a single
      range one. If it fails too, forget about ranges. Remember that until
      the death of the transport and propagates that to the clones.
      (Vincent Ladeuil, #62276, #62029).

    * Handles user/passwords supplied in url from command
      line (for the urllib implementation). Don't request already
      known passwords (Vincent Ladeuil, #42383, #44647, #48527)

    * _KnitIndex.add_versions() dictionary compresses revision ids as they
      are added. This fixes bug where fetching remote revisions records
      them as full references rather than integers. (John Arbash Meinel,
      #64789)

    * ``bzr ignore`` strips trailing slashes in patterns.
      Also ``bzr ignore`` rejects absolute paths. (Kent Gibson, #4559)

    * ``bzr ignore`` takes multiple arguments. (Cheuksan Edward Wang, #29488)

    * mv correctly handles paths that traverse symlinks.
      (Aaron Bentley, #66964)

    * Give nicer looking error messages when failing to connect over ssh.
      (John Arbash Meinel, #49172)

    * Pushing to a remote branch does not currently update the remote working
      tree. After a remote push, ``bzr status`` and ``bzr diff`` on the remote
      machine now show that the working tree is out of date.
      (Cheuksan Edward Wang #48136)

    * Use patiencediff instead of difflib for determining deltas to insert
      into knits. This avoids the O(N^3) behavior of difflib. Patience
      diff should be O(N^2). (Cheuksan Edward Wang, #65714)

    * Running ``bzr log`` on nonexistent file gives an error instead of the
      entire log history. (Cheuksan Edward Wang #50793)

    * ``bzr cat`` can look up contents of removed or renamed files. If the
      pathname is ambiguous, i.e. the files in the old and new trees have
      different id's, the default is the file in the new tree. The user can
      use "--name-from-revision" to select the file in the old tree.
      (Cheuksan Edward Wang, #30190)

Log message:
Update to 0.12:

bzr 0.12  2006-10-30

  IMPROVEMENTS:

    * ``bzr log`` now shows dotted-decimal revision numbers for all revisions,
      rather than just showing a decimal revision number for revisions on the
      mainline. These revision numbers are not yet accepted as input into bzr
      commands such as log, diff etc. (Robert Collins)

    * revisions can now be specified using dotted-decimal revision numbers.
      For instance, ``bzr diff -r 1.2.1..1.2.3. (Robert Collins)

    * ``bzr help commands`` output is now shorter (Aaron Bentley)

    * New connection: ``bzr+http://`` which supports tunnelling the smart
      protocol over an HTTP connection. If writing is enabled on the bzr
      server, then you can write over the http connection.
      (Andrew Bennetts)

    * ``bzr`` now uses lazy importing to reduce the startup time. This has
      a moderate effect on lots of actions, especially ones that have
      little to do. For example ``bzr rocks`` time is down to 116ms from
      283ms. (John Arbash Meinel)

    * New Registry class to provide name-to-object registry-like support,
      for example for schemes where plugins can register new classes to
      do certain tasks (e.g. log formatters). Also provides lazy registration
      to allow modules to be loaded on request. (John Arbash Meinel, Adeodato
      Simó)

  API INCOMPATABILITY:

    * LogFormatter subclasses show now expect the 'revno' parameter to
      show() to be a string rather than an int. (Robert Collins)

As well as changes to the internals, tests, and bug fixes.
