Notes When Upgrading
********************

* The kind() and is_executable() APIs on the WorkingTree interface no
  longer implicitly (read) locks and unlocks the tree. This *might*
  impact some plug-ins and tools using this part of the API. If you find
  an issue that may be caused by this change, please let us know,
  particularly the plug-in/tool maintainer. If encountered, the API
  fix is to surround kind() and is_executable() calls with lock_read()
  and unlock() like so::

    work_tree.lock_read()
    try:
        kind = work_tree.kind(...)
    finally:
        work_tree.unlock()

Internals
*********
* Rework of LogFormatter API to provide beginning/end of log hooks and to
  encapsulate the details of the revision to be logged in a LogRevision
  object.
  In long log formats, merge revision ids are only shown when --show-ids
  is specified, and are labelled "revision-id:", as per mainline
  revisions, instead of "merged:". (Kent Gibson)

* New ``BranchBuilder`` API which allows the construction of particular
  histories quickly. Useful for testing and potentially other applications
  too. (Robert Collins)

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

* There are two new help topics, working-trees and repositories that
  attempt to explain these concepts. (James Westby, John Arbash Meinel,
  Aaron Bentley)

* Added ``bzr log --limit`` to report a limited number of revisions.
  (Kent Gibson, #3659)

* Revert does not try to preserve file contents that were originally
  produced by reverting to a historical revision.  (Aaron Bentley)

* ``bzr log --short`` now includes ``[merge]`` for revisions which
  have more than one parent. This is a small improvement to help
  understanding what changes have occurred
  (John Arbash Meinel, #83887)

* TreeTransform avoids many renames when contructing large trees,
  improving speed.  3.25x speedups have been observed for construction of
  kernel-sized-trees, and checkouts are 1.28x faster.  (Aaron Bentley)

* Commit on large trees is now faster. In my environment, a commit of
  a small change to the Mozilla tree (55k files) has dropped from
  66 seconds to 32 seconds. For a small tree of 600 files, commit of a
  small change is 33% faster. (Ian Clatworthy)

* New --create-prefix option to bzr init, like for push.  (Daniel Watkins,
  #56322)

Bugfixes
********

* ``bzr push`` should only connect to the remote location one time.
  We have been connecting 3 times because we forget to pass around
  the Transport object. This adds ``BzrDir.clone_on_transport()``, so
  that we can pass in the Transport that we already have.
  (John Arbash Meinel, #75721)

* ``DirState.set_state_from_inventory()`` needs to properly order
  based on split paths, not just string paths.
  (John Arbash Meinel, #115947)

* Let TestUIFactoy encode the password prompt with its own stdout.
  (Vincent Ladeuil, #110204)

* pycurl should take use the range header that takes the range hint
  into account.
  (Vincent Ladeuil, #112719)

* WorkingTree4.get_file_sha1 no longer raises an exception when invoked
  on a missing file.  (Aaron Bentley, #118186)

* WorkingTree.remove works correctly with tree references, and when pwd is
  not the tree root. (Aaron Bentley)

* Merge no longer fails when a file is renamed in one tree and deleted
  in the other. (Aaron Bentley, #110279)

* ``revision-info`` now accepts dotted revnos, doesn't require a tree,
  and defaults to the last revision (Matthew Fuller, #90048)

* Tests no longer fail when BZR_REMOTE_PATH is set in the environment.
  (Daniel Watkins, #111958)

* ``bzr branch -r revid:foo`` can be used to branch any revision in
  your repository. (Previously Branch6 only supported revisions in your
  mainline). (John Arbash Meinel, #115343)
