What's New in Bazaar 2.3?
3
*************************
5
Bazaar 2.3 is still under development, and will be released in February
6
2011. This document accumulates a high level summary of what's changed.
8
:doc:`../release-notes/index` for a full list.
10
Users are encouraged to upgrade from the other stable series. This
11
document outlines the improvements in Bazaar 2.3 vs Bazaar 2.2. As well as
12
summarizing improvements made to the core product, it highlights
13
enhancements within the broader Bazaar world of potential interest to
16
Bazaar 2.3.0 is fully compatible both locally and on the network with 2.0
17
2.1, and 2.2, and can read and write repositories generated by all
23
* The ``lp:`` prefix will now use your known username (from
24
``bzr launchpad-login``) to expand ``~`` to your username. For example:
25
``bzr launchpad-login user && bzr push lp:~/project/branch`` will now
26
push to ``lp:~user/project/branch``. (John Arbash Meinel)

Performance improvements
29
************************
31
* ``bzr revert`` and ``bzr status`` are up to 15% faster on large trees
32
with many changes by not repeatedly building a list of all file-ids.
35
* ``bzr send`` uses less memory.
36
(John Arbash Meinel, #614576)
38
* Inventory entries now consume less memory (on 32-bit Ubuntu file entries
39
have dropped from 68 bytes to 40, and directory entries from 120 bytes
40
to 48). This affects most operations, and depending on the size of the
41
tree may substantially improve the speed of operations like ``bzr
42
commit``. (Andrew Bennetts)
44
* Lower memory consumption when reading many chk index pages. Helpful for
45
things like ``bzr co`` or ``bzr ls -R`` on large trees.
48
* When building new working trees, default to reading from the repository
49
rather than the source tree unless explicitly requested. (via
50
``--files-from`` and ``--hardlink`` for ``bzr branch`` and
51
``bzr checkout``. Generally, 2a format repositories extract
52
content faster than seeking and reading content from another tree,
53
especially in cold-cache situations. (John Arbash Meinel, #607298)
57
* A beta version of the documentation is now available in GNU TexInfo
58
format, used by emacs and the standalone ``info`` reader.
