- ---------------------

  NOTES WHEN UPGRADING:

  CHANGES:

    * Broader support of GNU Emacs mail clients. Set
      ``mail_client=emacsclient`` in your bazaar.conf and ``send`` will
      pop the bundle in a mail buffer according to the value of
      ``mail-user-agent`` variable. (Xavier Maillard)

  FEATURES:

  IMPROVEMENTS:

    * Diff now handles revision specs like "branch:" and "submit:" more
      efficiently.  (Aaron Bentley)

    * More friendly error given when attempt to start the smart server
      on an address already in use. (Andrea Corbellini, #200575)

    * Pull completes much faster when there is nothing to pull.
      (Aaron Bentley)

  BUGFIXES:

    * Authentication.conf can define sections without password.
      (Vincent Ladeuil, #199440)

    * Avoid muttering every time a child update does not cause a
      progress bar update. (John Arbash Meinel, #213771)

    * ``Branch.reconcile()`` is now implemented. This allows ``bzr
      reconcile`` to fix when a Branch has a non-canonical mainline
      history. ``bzr check`` also detects this condition.
      (John Arbash Meinel, #177855)

    * ``bzr commit`` now works with Microsoft's FTP service.
      (Andreas Deininger)

    * Catch definitions outside sections in authentication.conf.
      (Vincent Ladeuil, #217650)

    * Conversion from non-rich-root to rich-root(-pack) updates
      inventory sha1s, even when bundles are used.
      (Aaron Bentley, #181391)

    * Conversion from non-rich-root to rich-root(-pack) works correctly
      even though search keys are not topologically sorted.
      (Aaron Bentley)

    * Conversion from non-rich-root to rich-root(-pack) works even when
      a parent revision has a different root id.
      (Aaron Bentley, #177874)

    * Disable strace testing until strace is fixed (see bug #103133) and
      emit a warning when selftest ends to remind us of leaking tests.
      (Vincent Ladeuil, #226769)

    * Fetching all revisions from a repository does not cause pack
      collisions.  (Robert Collins, Aaron Bentley, #212908)

    * Fix error about "attempt to add line-delta in non-delta knit".
      (Andrew Bennetts, #217701)

    * Pushing a branch in "dirstate" format (Branch5) over bzr+ssh would
      break if the remote server was < version 1.2. This was due to a
      bug in the RemoteRepository.get_parent_map() fallback code.
      (John Arbash Meinel, #214894)

    * Remove leftover code in ``bzr_branch`` that inappropriately
      creates a ``branch-name`` file in the branch control directory.
      (Martin Pool)

    * Set SO_REUSEADDR on server sockets of ``bzr serve`` to avoid
      problems rebinding the socket when starting the server a second
      time.  (John Arbash Meinel, Martin Pool, #164288)

    * Severe performance degradation in fetching from knit repositories
      to knits and packs due to parsing the entire revisions.kndx on
      every graph walk iteration fixed by using the Repository.get_graph
      API.  There was another regression in knit => knit fetching which
      re-read the index for every revision each side had in common.
      (Robert Collins, John Arbash Meinel)

    * When logging the changes to a particular file, there was a bug if
      there were ghosts in the revision ancestry.
      (John Arbash Meinel, #209948)

  DOCUMENTATION:

    * Expanded the User Guide to include new chapters on popular plugins
      and integrating Bazaar into your environment. The *Best practices*
      chapter was renamed to *Miscellaneous topics* as suggested by
      community feedback as well. (Ian Clatworthy)

    * Document outlining strategies for TortoiseBzr. (Mark Hammond)

    * Improved the documentation on hooks. (Ian Clatworthy)

    * Update authentication docs regarding ssh agents.
      (Vincent Ladeuil, #183705)

  TESTING:

    * Add ``thread_name_suffix`` parameter to
      SmartTCPServer_for_testing, to make it easy to identify which test
      spawned a thread with an unhandled exception. (Andrew Bennetts)

    * New ``--debugflag``/``-E`` option to ``bzr selftest`` for setting
      options for debugging tests, these are complementary to the the -D
      options.  The ``-Dselftest_debug`` global option has been replaced
      by the ``-E=allow_debug`` option for selftest. (Andrew Bennetts)

    * Parameterised test ids are preserved correctly to aid diagnosis of
      test failures. (Robert Collins, Andrew Bennetts)

    * The test suite modules have been modified to define load_tests()
      instead of test_suite(). That speeds up selective loading (via
      --load-list) significantly and provides many examples on how to
      migrate (grep for load_tests).  (Vincent Ladeuil)

  INTERNALS:

    * ``Hooks.install_hook`` is now deprecated in favour of
      ``Hooks.install_named_hook`` which adds a required ``name``
      parameter, to avoid having to call ``Hooks.name_hook``.
      (Daniel Watkins)

    * Implement xml8 serializer.  (Aaron Bentley)

    * New form ``@deprecated_method(deprecated_in(1, 5, 0))`` for making
      deprecation wrappers.  (Martin Pool)

    * ``Repository.revision_parents`` is now deprecated in favour of
      ``Repository.get_parent_map([revid])[revid]``. (Jelmer Vernooij)

    * The Python ``assert`` statement is no longer used in Bazaar
      source, and a test checks this.  (Martin Pool)

  API BREAKS:

    * ``bzrlib.status.show_pending_merges`` requires the repository to
      be locked by the caller. Callers should have been doing it anyway,
      but it will now raise an exception if they do not.
      (John Arbash Meinel)

    * Repository.get_data_stream,
      Repository.get_data_stream_for_search(),
      Repository.get_deltas_for_revsions(), Repository.revision_trees(),
      Repository.item_keys_introduced_by() no longer take read locks.
      (Aaron Bentley)

    * ``LockableFiles.get_utf8`` is deprecated, as a start towards
      removing LockableFiles and ``.control_files`` entirely.
      (Martin Pool)

    * Methods deprecated prior to 1.1 have been removed.
      (Martin Pool)
