Bazaar 2.3 has been released on the 3rd of February 2011 and marks the start
6
of another long-term-stable series. From here, we will only make bugfix
7
releases on the 2.3 series (2.3.1, etc), while 2.4 will become our new
8
development series. The 2.1 and 2.2 series will also continue to get
9
bugfixes. (Currently 2.0 is planned to be EOLed circa September 2011.)

20
Bazaar 2.3.1 includes all the fixes in the un-released 2.0.7, 2.1.4 and 2.2.5
21
versions that weren't included in 2.3.0 and fixes some bugs on its own.

See the :doc:`../release-notes/index` for details.
25
Bazaar 2.3 is fully compatible both locally and on the network with 2.0, 2.1,
26
and 2.2. It can read and write repositories generated by all previous
32
* Committing a new revision in a stacked branch is now supported, as long as
33
you are using the current repository format (2a). It will preserve the
34
stacking invariants, etc, so that fetching after commit is guaranteed to
35
work. (John Arbash Meinel, #375013)
37
* Support for some old development formats have been removed:
38
``development-rich-root``, ``development6-rich-root``, and
39
``development7-rich-root``. These formats were always labelled experimental
40
and not used unless the user specifically asked for them. If you have
41
repositories using these old formats you should upgrade them to ``2a`` using
42
Bazaar 2.2. (Andrew Bennetts)
23
44
* The default ``ignore`` file created by Bazaar will contain ``__pycache__``,
24
45
which is the name of the directory that will be used by Python to store
31
52
get the old behavior, one can use ``bzr tags --sort=alpha``.
32
53
(Neil Martinsen-Burrell, #640760)
55
* On platforms other than Windows and Mac OS X, Bazaar will use configuration
56
files that live in $XDG_CONFIG_HOME/bazaar if that directory exists. This
57
allows interested individuals to conform to the XDG Base Directory
58
specification. The plugin location has not changed and is still
59
~/.bazaar/plugins. To use a different directory for plugins, use the
60
environment variable BZR_PLUGIN_PATH. (Neil Martinsen-Burrell, #195397)
62
* ``bzr upgrade`` now operates recursively when run on a shared
63
repository, automatically upgrading the branches within it, and has
64
grown additional options for showing what it will do and cleaning up
65
after itself. (Ian Clatworthy, Matthew Fuller, #89830, #374734, #422450)

Launchpad integration

*********************
39
72
``bzr launchpad-login user && bzr push lp:~/project/branch`` will now
40
73
push to ``lp:~user/project/branch``. (John Arbash Meinel)
75
* Launchpad has announced that the ``edge.launchpad.net`` instance is
76
deprecated and may be shut down in the future
77
<http://blog.launchpad.net/general/edge-is-deprecated>. Bazaar has therefore
78
been updated in this release to talk to the main (``launchpad.net``) servers,
79
rather than the ``edge`` ones.

Performance improvements

************************

88
* ``bzr send`` uses less memory.
50
89
(John Arbash Meinel, #614576)
91
* Fetches involving stacked branches and branches with tags now do slightly less
92
I/O, and so does branching from an existing branch. This also improves the
93
network performance of these operations. (Andrew Bennetts)
52
95
* Inventory entries now consume less memory (on 32-bit Ubuntu file entries
53
96
have dropped from 68 bytes to 40, and directory entries from 120 bytes
54
97
to 48). This affects most operations, and depending on the size of the
111
154
default behaviour is specified (if needed) by setting the variable to
112
155
``conflict``. (Vincent Ladeuil, #323111)
157
* ``bzr resolve --take-this`` and ``bzr resolve --take-other`` can now be
158
used for text conflicts. This will ignore the differences that were merged
159
cleanly and replace the file with its content in the current branch
160
(``--take-this``) or with its content in the merged branch
161
(``--take-other``). (Vincent Ladeuil, #638451)
163
* ``bzr resolve`` now provides more feedback about the conflicts just
164
resolved and the remaining ones. (Vincent Ladeuil)
124
``bzr`` can be configure via environment variables, command-line options
176
``bzr`` can be configured via environment variables, command-line options
125
177
and configurations files. We've started working on unifying this and give
126
178
access to more options. The first step is a new ``bzr config`` command that
127
179
can be used to display the active configuration options in the current
128
working tree or branch as well as the ability to set or remove an option.

Expected releases for the 2.3 series
131
************************************
133
The 2.3 series has entered the beta phase and 2.3.0 should be released soon
134
enough to be included into Natty Narwhal.
136
As a rough estimate, consider that 2.3.0 will be released in February
137
2011 and be supported until August 2012. Additional releases will be
138
made if critical bugs are encountered
180
working tree or branch as well as the ability to set or remove an
181
option. Scripts can also use it to get only the value for a given option.
