  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)
