 Compatibility Breaks
 ********************

+* bzrlib library users now need to call ``__enter__`` and ``__exit__`` on
+  the result of ``bzrlib.initialize``. This change was made when fixing
+  the bad habit recent bzr versions have had of leaving progress bars
+  behind on the screen. That required calling another function before
+  exiting the program, and it made sense to provide a full context
+  manager at the same time. (Robert Collins)
+
+* The ``bzr`` front end now requires a ``bzrlib.ui.ui_factory`` which is a
+  context manager in the Python 2.5 and above sense. The bzrlib base class
+  is such a manager, but third party UI factories which do not derive from
+  ``bzrlib.ui.UIFactory`` will be incompatible with the command line front
+  end.
+
 * URLs like ``foo:bar/baz`` are now always parsed as a URL with scheme "foo"
   and path "bar/baz", even if bzr does not recognize "foo" as a known URL
   scheme.  Previously these URLs would be treated as local paths.
