External Compatibility Breaks

New Features
************
* The ``log_format`` configuration can be used with ``-Olog_format=line`` to
change the format ``push`` and ``pull`` use to display the
revisions. I.e.: ``bzr pull -v -Olog_format=short`` will use the ``short``
format instead of the default ``long`` one. (Vincent Ladeuil, #861472)
* The new config scheme allows an alternative syntax for the 'appenpath'
policy relying on option expansion and defining a new 'relpath' option
local to a section. Instead of using '<option>:policy=appendpath', the
option value can de defined as 'option=xxxx/{relpath}'.
(Vincent Ladeuil, #832013)
Improvements
************
* ``bzr info -v`` now shows the number of colocated branches
for control directories that support them.
(Jelmer Vernooij, #863285)
* ``bzr version-info`` now takes a ``--revision`` argument.
(Jelmer Vernooij, #238705)
* ``bzr revno`` now takes a ``--revision`` argument.
(Jelmer Vernooij, #870649)
* ``bzr serve`` now can serve from URLs rather than just from the
file system. I.e.: ``bzr serve -d lp:bzr`` or
``bzr serve -d file:///data/bzr`` (Jelmer Vernooij)
* all input prompts are now char-based when possible, and can be forced to
line-based mode by setting the ``BZR_TEXTUI_INPUT`` environment variable
to 'line-based'. This replace the previous shelf UI only patch using
``INSIDE_EMACS``. (Benoît Pierre)
Bug Fixes
*********
* ``bzr info`` now shows the master branch location too for
treeless local branches. (Jelmer Vernooij, #258355)
* ``bzr mkdir --quiet`` now does not print a line for every created
directory. (Martin von Gagern, #869915)
* ``bzr mv`` does not crash when attempting to move the root of a
branch. (Jonathan Riddell, #809728)
* ``bzr shelve`` now use ``UIFactory.choose`` for input handling, making
it usable when creating a custom ``UIFactory`` implementation. (Benoît
Pierre)
* ``bzr clean-tree`` now use ``UIFactory.get_boolean`` for confirmation
prompt, making it usable when using a custom ``UIFactory``
implementation. (Benoît Pierre)
* If sending a crash through Apport fails report the Apport failure to
bzr.log rather than stderr. (Jonathan Riddell, #766735)
* ``bzr upgrade`` no longer treats 'already up-to-date' exceptions as
errors. (Benoît Pierre, #716560).
* ``bzr version-info`` no longer populates the clean state for custom
templates unless {clean} is explicitly asked for.
(Lawrence Mitchell, #882541)
* Fix finding the CPU count when using Python >= 2.6 on BSD-based systems.
(Jelmer Vernooij, #887151)
* ``WorkingTree.clone()`` now supports its ``revision_id`` being set
to the null revision. (Jelmer Vernooij, #876423)
* ``WorkingTree.pull`` can now pull ``NULL_REVISION``.
(Jelmer Vernooij, #887556)
API Changes
***********
* ``Branch.revision_history`` is now deprecated. (Jelmer Vernooij, #799519)
* Methods ``add`` and ``items`` of ``LRUCache`` and ``LRUSizeCache`` are
deprecated. Use normal dict-style access instead. (Martin Packman)
* New flag ``RepositoryFormat.supports_unreferenced_revisions`` which
indicates whether revisions can be present in a repository without
being referenced from e.g. a branch history at the same time.
(Jelmer Vernooij)
* ``UIFactory.choose`` has been added: prompt the user for a list of
choices. (Benoît Pierre)
Internals
*********
* ``ControlDirFormat`` now has a new method ``supports_transport``
which format implementations can use whether or not they can access
a control dir over a particular transport. (Jelmer Vernooij)
* ``BranchBuilder.build_commit`` now take ``parent_ids`` and
``allow_leftmost_as_ghost`` arguments. (Jelmer Vernooij)
Testing
*******
* Ensure TestCase instances are deallocated immediately after running where
possible. This greatly reduces the peak resource needs of a full test suite
run. The new ``-Euncollected_cases`` selftest flag will add failures if any
case which persists pasts its expected lifetime. (Martin Packman, #613247)
* Report exceptions from child processes during fork instead of swallowing the
error and reporting that everything went okay. (Martin Packman, #804130)
