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.
23
Bazaar 2.3.2 is a bugfix release that was never released.
25
Bazaar 2.3.3 is a bugfix release including the fixes in 2.3.2 and
26
fixing the test helpers deprecated by python-2.7.
28
Bazaar 2.3.4 is a bugfix release.
30
See the :doc:`../release-notes/index` for details.
32
Bazaar 2.3 is fully compatible both locally and on the network with 2.0, 2.1,
33
and 2.2. It can read and write repositories generated by all previous
39
* Committing a new revision in a stacked branch is now supported, as long as
40
you are using the current repository format (2a). It will preserve the
41
stacking invariants, etc, so that fetching after commit is guaranteed to
42
work. (John Arbash Meinel, #375013)
44
* Support for some old development formats have been removed:
45
``development-rich-root``, ``development6-rich-root``, and
46
``development7-rich-root``. These formats were always labelled experimental
47
and not used unless the user specifically asked for them. If you have
48
repositories using these old formats you should upgrade them to ``2a`` using
49
Bazaar 2.2. (Andrew Bennetts)
23
51
* The default ``ignore`` file created by Bazaar will contain ``__pycache__``,
24
52
which is the name of the directory that will be used by Python to store
31
59
get the old behavior, one can use ``bzr tags --sort=alpha``.
32
60
(Neil Martinsen-Burrell, #640760)
62
* On platforms other than Windows and Mac OS X, Bazaar will use configuration
63
files that live in $XDG_CONFIG_HOME/bazaar if that directory exists. This
64
allows interested individuals to conform to the XDG Base Directory
65
specification. The plugin location has not changed and is still
66
~/.bazaar/plugins. To use a different directory for plugins, use the
67
environment variable BZR_PLUGIN_PATH. (Neil Martinsen-Burrell, #195397)
69
* ``bzr upgrade`` now operates recursively when run on a shared
70
repository, automatically upgrading the branches within it, and has
71
grown additional options for showing what it will do and cleaning up
72
after itself. (Ian Clatworthy, Matthew Fuller, #89830, #374734, #422450)

Launchpad integration

75
*********************
39
79
``bzr launchpad-login user && bzr push lp:~/project/branch`` will now
40
80
push to ``lp:~user/project/branch``. (John Arbash Meinel)
82
* Launchpad has announced that the ``edge.launchpad.net`` instance is
83
deprecated and may be shut down in the future
84
<http://blog.launchpad.net/general/edge-is-deprecated>. Bazaar has therefore
85
been updated in this release to talk to the main (``launchpad.net``) servers,
86
rather than the ``edge`` ones.

Performance improvements

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

95
* ``bzr send`` uses less memory.
50
96
(John Arbash Meinel, #614576)
98
* Fetches involving stacked branches and branches with tags now do slightly less
99
I/O, and so does branching from an existing branch. This also improves the
100
network performance of these operations. (Andrew Bennetts)
52
102
* Inventory entries now consume less memory (on 32-bit Ubuntu file entries
53
103
have dropped from 68 bytes to 40, and directory entries from 120 bytes
54
104
to 48). This affects most operations, and depending on the size of the
111
161
default behaviour is specified (if needed) by setting the variable to
112
162
``conflict``. (Vincent Ladeuil, #323111)
164
* ``bzr resolve --take-this`` and ``bzr resolve --take-other`` can now be
165
used for text conflicts. This will ignore the differences that were merged
166
cleanly and replace the file with its content in the current branch
167
(``--take-this``) or with its content in the merged branch
168
(``--take-other``). (Vincent Ladeuil, #638451)
170
* ``bzr resolve`` now provides more feedback about the conflicts just
171
resolved and the remaining ones. (Vincent Ladeuil)
124
``bzr`` can be configure via environment variables, command-line options
183
``bzr`` can be configured via environment variables, command-line options
125
184
and configurations files. We've started working on unifying this and give
126
185
access to more options. The first step is a new ``bzr config`` command that
127
186
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
187
working tree or branch as well as the ability to set or remove an
188
option. Scripts can also use it to get only the value for a given option.
