bzr 1.13.1 2009-03-19
---------------------
A couple regessions where found in the 1.13 release. The pyrex-generated C
extensions are missing from the .tar.gz and .zip files.  Documentation on how
to generate GNU ChangeLogs is wrong.

  BUG FIXES:

    * Change ``./bzr``'s ``_script_version`` to match ./bzrlib/__init__.py
      version_info. (Bob Tanner, Martin Pool, #345232)

    * Distribution archives for 1.13 do not contain generated C extension
      modules (Jean-Francois Roy, Bob Tanner, #344465)

    * GNU ChangeLog output can now be produced by bzr log --format
      gnu-changelog is incorrect (Deejay, Bob Tanner, Martin Pool,
      Robert Collins, #343928)

    * ``merge --force`` works again. (Robert Collins, #342105)
