Bazaar Release Notes
####################

.. toctree::
   :maxdepth: 1

bzr 2.6b3
#########

:2.6b3: NOT RELEASED YET

External Compatibility Breaks
*****************************

.. These may require users to change the way they use Bazaar.

New Features
************

* ``bzr switch --store`` now stores uncommitted changes in the branch, and
  restores them when switching back to the branch. (Aaron Bentley)

* New option '--context' for 'bzr diff' command, to configure the amount of 
  context (i.e. showing lines that have not changed).  Also available as the 
  named parameter 'context_lines' to bzrlib.diff.internal_diff(). (Paul Nixon)

* The 'ping' plugin is now shipped with bzr. (Jelmer Vernooij)

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

* ``bzr help env-variables`` now points users at ``bzr help configuration``
  which has much more detailed information on the same stuff.
  (Robert Collins)

* ``bzr lp-find-proposal`` now only cares about the revision-id that is
  specified, not the branch you use.  This was enabled by a new API call in
  Launchpad's web service.  (Aaron Bentley)

* Implement authentication.conf password obfuscation, the password_encoding
  option can now be set to base64. (Florian Dorn)

* Local configurations files (i.e. accessed on the local file system like
  ``bazaar.conf`` and ``locations.conf``) are now shared, reducing the
  number of IOs when querying a configuation option. (Vincent Ladeuil, #832042)

Bug Fixes
*********

* Add a ``progress_bar`` configuration option defaulting to
  ``BZR_PROGRESS_BAR``. This can be set in ``bazaar.conf`` or specified from
  the command line with ``-Oprogress_bar=text``. (Vincent Ladeuil, #388275)

* Fixed a bug where the entire contents of ``/etc/mailname`` is read in.
  We only want to read in the first line so that comments could be added
  and would be ignored.
  (Haw Loeung, #932515)

* Warn when ``--show-base`` is used for ``pull`` in a treeless branch
  instead of failing. It's useless but harmless. (Vincent Ladeuil, #1022160)

* When a missing referenced chk root error is encountered, bzr now suggests
  running ``bzr reconcile --canonicalize-chks``. (Jelmer Vernooij, #1021537)

* When pushing a specific revision, create the new working tree at
  that revision. (#484516, Neil Martinsen-Burrell)

Documentation
*************

.. Improved or updated documentation.

* Clarify ``bzr config`` usages especially around other option references
  expansion. (Vincent Ladeuil, #996401)

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

.. Changes that may require updates in plugins or other code that uses
   bzrlib.

Internals
*********

* The launchpad plugin now requires API 1.6.0 or later.  This version shipped
  with Ubuntu 9.10.  (Aaron Bentley)

Testing
*******

.. Fixes and changes that are only relevant to bzr's test framework and 
   suite.  This can include new facilities for writing tests, fixes to 
   spurious test failures and changes to the way things should be tested.


bzr 2.6b2
#########

:2.6b2: 2012-09-10

August 2012.

New Features
************

  (Jelmer Vernooij, #681792)

* The 'grep' plugin is now shipped with bzr. (Jelmer Vernooij)

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

  the more complex 'file://.,branch=NAME'. (Jelmer Vernooij, #833665)

Bug Fixes
*********

* "bzr missing" now shows tag names when displaying revision information.
  (#559072, Neil Martinsen-Burrell)

* Fix ``branch.conf`` saving when unlocking the branch for BranchFormat4.

* Implement ``ResponseFile.readline`` and ``ReponseFile.tell``,
  fixing some clones over HTTP. (Jelmer Vernooij, #963769)

  is finally unlocked. (Vincent Ladeuil, #948339)

Documentation
*************

* Document "bzr lp-propose", "bzr register-branch" and
  the other Launchpad plugin commands in bzr(1).
  (Jelmer Vernooij, #843801, #163995)

* Force format registration to avoid generate_docs.py traceback when the
  registry is empty. (Vincent Ladeuil, #956860)

* Generate ``ENVIRONMENT`` section in bzr(1) from known environment variable
  list rather than hardcoding. (Jelmer Vernooij, #197618)


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

* ``register_filter_stack_map`` and ``lazy_register_filter_stack_map``
  are noew deprecated. Instead, use ``filter_stacks_registry.register``
  and ``filter_stacks_registry.register_lazy``.

Internals
*********

None.

Testing
*******

* Fix test failures by removing a remaining reference to ``features.sphinx``
  which isn't needed anymore since we don't test the texinfo sphinx builder
  anymore either. (Vincent Ladeuil)

bzr 2.6b1
#########

with 2.6b1.

External Compatibility Breaks
*****************************

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

* Access to HTTPS URLs now uses the urrllib implementation by default.
  For the old pycurl-based implementation, specify ``https+pycurl://`` as
  the URL scheme when accessing a HTTPS location.
  (Jelmer Vernooij, #125055)

* Add short option alias ``-N`` for ``--no-recurse``.

  an old style Config object. (Jelmer Vernooij)

* New method ``Repository.verify_revision_signatures``.
  (Jelmer Vernooij)

* New configuration option class ``RegistryOption`` which is backed
