What's New in Bazaar 2.4?
3
*************************
5
Bazaar 2.4 is still under development, and will be released in August 2011.
6
This document accumulates a high level summary of what's changed. See the
7
:doc:`../release-notes/index` for a full list.
9
Users are encouraged to upgrade from the other stable series. This
10
document outlines the improvements in Bazaar 2.4 vs Bazaar 2.3. As well as
11
summarizing improvements made to the core product, it highlights
12
enhancements within the broader Bazaar world of potential interest to
15
Bazaar 2.4.0 is fully compatible both locally and on the network with 2.0,
16
2.1, 2.2 and 2.3, and can read and write repositories generated by all
22
External merge tool configuration has been added to ``bzr`` core. The name
23
and commandline of one or more external merge tools can be defined in
24
bazaar.conf. See the help topic ``configuration`` for more details.
26
Tagged Revisions are Copied
27
***************************
29
When tags are copied from a branch, the associated revisions are now copied
30
too. Previously operations like branching, merging or pulling might have
31
copied new tags visible in ``bzr tags``, but not copied the revisions. Now
32
revisions from tags will always be present, so that operations like ``bzr
33
log -r tag:foo`` will always work.
38
Option values can now refer to other options in the same configuration file by
39
enclosing them in curly brackets (``{option}``). This is an opt-in feature
40
during the beta period controlled by the ``bzr.config.expand`` option that
41
should be declared in ``bazaar.conf`` and no other file.
43
Changelog merge plugin
44
**********************
46
The ``changelog_merge`` plugin has been added. It provides a merge hook
47
to automate merging of changes to ``ChangeLog`` files in GNU's change log
48
format. Refer to ``bzr help changelog_merge`` for documentation on how to
49
enable it and what it can do.
