Bazaar full changelog

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.
· Add short option alias ``-N`` for ``--no-recurse``.
· Avoid 'Invalid range access' errors when whole files are retrieved with transport.http.get() .
· ``bzr rmbranch`` now supports removing colocated branches.
· ``bzr rmbranch`` no longer removes active branches unless ``--force`` is specified.
· ``bzr verify-signatures`` now shows a progress bar.
· Two new command hooks, ``pre_command`` and ``post_command``, provide notification before and after a command has been run.

Bug Fixes:
· Fix ``bzr config`` display for ``RegistryOption`` values.

API Changes:
· ``GPGStrategy.do_verifications`` has been deprecated.
· File ids in the ``Tree`` API can now be bytestring as previously, or tuples of bytestrings.

External Compatibility Breaks:
· The '.bzr/branch/email' file is no longer read to determine the users' identity. Instead, the 'email' setting in '.bzr/branch/branch.conf' should be used. (Jelmer Vernooij, #903894)

New Features:
· quot;bzr mkdirquot; now includes -p (--parents) option for recursively adding parent directories. (Jared Hance, Jelmer Vernooij, #253529)
· ``config.Option`` can now declare ``override_from_env``, a list of environment variables which, when set, that takes precedence over values defined in configuration files. (Vincent Ladeuil, #907279)

Improvements:
· New HPSS call for ``Repository.reconcile``. (Jelmer Vernooij, #894455)
· Merge now has two new hooks ``pre_merge`` and ``post_merge`` that are called before and after a merge and can make additional modifications to the trees involved. (Jelmer Vernooij, #906877)
· Override the value returned by ``sys.getfilesystemencoding()`` for the bzr script to utf-8 when it would otherwise be ascii on a posix system.

New Features:
· Provides a ``po_merge`` plugin to automatically merge ``.po`` files with ``msgmerge``. See ``bzr help po_merge`` for details. (Vincent Ladeuil, #884270)

Improvements:
· ``bzr branch --stacked`` now only makes a single connection to the remote server rather than three. (Jelmer Vernooij, #444293)
· ``bzr export --uncommitted`` will export the uncommitted tree. (Jelmer Vernooij, #555613)
· ``bzr rmbranch`` can now remove colocated branches. (Jelmer Vernooij, #831464)
· ``bzr status`` no longer shows shelves if files are specified. (Francis Devereux)
· ``bzr switch`` now accepts colocated branch names to switch to. (Jelmer Vernooij, #826814)
· Plugins can now register additional quot;location aliasesquot;. (Jelmer Vernooij)
· Revision specifiers will now only browse as much history as they need to, rather than grabbing the whole history unnecessarily in some cases. (Jelmer Vernooij)

New Features:
· A ``from_unicode`` parameter can be specified when registering a config option. This implements boolean, integer and list config options when the provided ``bool_from_store``, ``int_from_store`` and ``list_from_store`` are used for this parameter. (Vincent Ladeuil)
· Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now checks to see if the most recent published source package version for that project is present in the branch tags. This should help developers trust whether the packaging branch is up-to-date and can be used for new changes. The level of verbosity is controlled by the config item ``launchpad.packaging_verbosity``
· Add a config option gpg_signing_key for setting which GPG key should be used to sign commits. Also default to using the gpg user identity which matches user_email() as set by whoami. (Jonathan Riddell, #68501)

Bug Fixes:
· Accept some differences for ``bound_location`` from the config files that were leading to a 'ReadOnlyError: A write attempt was made in a read only transaction' error.
· Don't fail with traceback if `bzr serve` is running as a service on Windows, and there is no USERNAME, nor BZR_EMAIL or other whoami-related environment variables set.

External Compatibility Breaks:
· Do not treat configuration option 'check_signatures = require' as if it were 'create_signatures = always'

New Features:
· Hooks have been added for config stacks: ``get``, ``set`` and ``remove`` are called when an option is repsectively read, modified or deleted. Also added ``load`` and ``save`` hooks for config stores, called when the stores are loaded or saved.
· New hook server_exception in bzrlib.smart.server to catch any exception caused while running bzr serve.
· New hook set_commit_message in bzrlib.msgeditor to set a commit message and revision properties.
· Support ``-S`` as an alias for ``--short`` for the ``log`` and ``missing`` commands.

Improvements:
· ``bzr annotate`` can be run without setting whoami data first.

External Compatibility Breaks:
· ``bzr-2.4`` has officially dropped support for python2.4 and python2.5. We will continue to maintain ``bzr-2.3`` for people who still need to use those versions of python. (John Arbash Meinel)

New Features:
· The text compressor used for 2a repositories now has a tweakable parameter that can be set in bazaar.conf. ``bzr.groupcompress.max_entries_per_source`` default of 65536. When doing compression, we build up an index of locations to match against. Setting this higher will result in slightly better compression, at a cost of more memory. Note that a value of 65k represents fully sampling a 1MB file. So this only has an effect when compressing texts larger than N*16 bytes. (John Arbash Meinel, #602614)

Improvements:
· ``bzr branch --stacked`` from a smart server uses the network a little more efficiently. For a simple branch it reduces the number of round-trips by about 20%. (Andrew Bennetts)

Bug Fixes:
· Correctly resolve text conflicts for files in subdirs.
· Fix quot;AssertionError: repository.user_url ... does not match URL from server responsequot; when reusing a smart transport.
· Restore proper logging of bytes transferred. We accidentally reset the counter when commands finished before we logged the total transferred.
· This is a bugfix and polish release over the 2.2 series, with a large number of bugs fixed (>130), and some performance improvements. Some features have been enhanced including commits on stacked branches, upgrades of related branches, shortcut URL schemes for ubuntu and debian on launchpad and better conflict resolution.
· Only bugfixes from other stables series have been included since 2.3b5 so all known fixed bugs are included here.

· This release marks the start of another long-term-stable series. From here, we will only make bugfix releases on the 2.3 series (2.3.1, etc, and support it until August 2012), while 2.4 will become our new development series. The 2.1 and 2.2 series will also continue to get bugfixes. (Currently 2.0 is planned to be EOLed circa September 2011 and will receive only critical bugfixes.)
