This release fixes two small but worthwhile bugs relevant to users on
Microsoft Windows: some commands that failed on with locking errors will
now work, and a bug that caused poor performance after committing a file
with line-ending conversion has now been fixed.  It also fixes a bug in
pushing to older servers.

Bug Fixes
*********

* Fixed a problem where using content filtering and especially end-of-line
  conversion will commit too many copies a file.
  (Martin Pool, #415508)

* Fix assertion error about ``_remember_remote_is_before`` in
  ``set_tags_bytes`` when pushing to older smart servers.  
  (Andrew Bennetts, Alexander Belchenko, #418931)

Improvements
************

* ``bzr push`` locally on Windows will no longer give a locking error with
  dirstate based formats. (Robert Collins)

* ``bzr shelve`` and ``bzr unshelve`` now work on Windows.
  (Robert Collins, #305006)

API Changes
***********

* ``bzrlib.shelf_ui`` has had the ``from_args`` convenience methods of its
  classes changed to manage lock lifetime of the trees they open in a way
  consistent with reader-exclusive locks. (Robert Collins, #305006)

* ``Tree.path_content_summary`` may return a size of None, when called on
  a tree with content filtering where the size of the canonical form
  cannot be cheaply determined.  (Martin Pool)

* When manually creating transport servers in test cases, a new helper
  ``TestCase.start_server`` that registers a cleanup and starts the server
  should be used. (Robert Collins)
