* ``pull``, ``merge`` and ``push`` will no longer silently correct some
  repository index errors that occured as a result of the Weave disk format.
  Instead the ``reconcile`` command needs to be run to correct those
  problems if they exist (and it has been able to fix most such problems
  since bzr 0.8). Some new problems have been identified during this release
  and you should run ``bzr check`` once on every repository to see if you
  need to reconcile. If you cannot ``pull`` or ``merge`` from a remote
  repository due to mismatched parent errors - a symptom of index errors -
  you should simply take a full copy of that remote repository to a clean
  directory outside any local repositories, then run reconcile on it, and
  finally pull from it locally. (And naturally email the repositories owner
  to ask them to upgrade and run reconcile).
  (Robert Collins)

* ``VersionedFile.fix_parents`` has been removed as a harmful API.
  ``VersionedFile.join`` will no longer accept different parents on either
  side of a join - it will either ignore them, or error, depending on the
  implementation. See notes when upgrading for more information.
