    - http://www.reviewboard.org/docs/releasenotes/dev/rbtools/0.4.3/
    - New Features:
        * Added support for posting from Bazaar repositories
        * Passing --basedir to post-review will override the computed base
          directory used for Subversion diffs
        * Added better support for moved files in Perforce
    - Bug Fixes:
        * General:
          * Fixed problems authenticating with the server when anonymous access is
            disabled
          * Fixed loading settings from the user’s ~/.reviewboardrc when it’s the
            only .reviewboardrc in the search path
          * Fixed a crash when the user’s home directory isn’t writable
          * Added a fallback when failing to get the API version from a Review
            Board server
          * The "Username" prompt is now printed to stderr instead of stdout, to
            match the “Password” prompt’s inputted text
          * Unicode URLs are now encoded as UTF-8, preventing an encoding conflict
            when talking to Review Board
        * Git:
          * Git diffs no longer contain move/rename information if the Review Board
            server doesn’t support it
        * Mercurial:
          * Fixed --guess-summary when it has newline characters in it
        * Subversion:
          * Fixed problems generating diffs containing deleted files
