What's New in Bazaar 2.3?
*************************

Bazaar 2.3 is still under development, and will be released in February
2011.  This document accumulates a high level summary of what's changed.
See the
:doc:`../release-notes/index` for a full list.

Users are encouraged to upgrade from the other stable series.  This
document outlines the improvements in Bazaar 2.3 vs Bazaar 2.2. As well as
summarizing improvements made to the core product, it highlights
enhancements within the broader Bazaar world of potential interest to
those upgrading.

Bazaar 2.3.0 is fully compatible both locally and on the network with 2.0
2.1, and 2.2, and can read and write repositories generated by all
previous versions.

Launchpad integration
*********************

* The ``lp:`` prefix will now use your known username (from
  ``bzr launchpad-login``) to expand ``~`` to your username.  For example:
  ``bzr launchpad-login user && bzr push lp:~/project/branch`` will now
  push to ``lp:~user/project/branch``.  (John Arbash Meinel)

Performance improvements
************************

* ``bzr revert`` and ``bzr status`` are up to 15% faster on large trees
  with many changes by not repeatedly building a list of all file-ids.
  (Andrew Bennetts)

* ``bzr send`` uses less memory.  
  (John Arbash Meinel, #614576)

* Inventory entries now consume less memory (on 32-bit Ubuntu file entries
  have dropped from 68 bytes to 40, and directory entries from 120 bytes
  to 48).  This affects most operations, and depending on the size of the
  tree may substantially improve the speed of operations like ``bzr
  commit``.  (Andrew Bennetts)

* Lower memory consumption when reading many chk index pages. Helpful for
  things like ``bzr co`` or ``bzr ls -R`` on large trees.
  (John Arbash Meinel)

* When building new working trees, default to reading from the repository
  rather than the source tree unless explicitly requested. (via
  ``--files-from`` and ``--hardlink`` for ``bzr branch`` and
  ``bzr checkout``. Generally, 2a format repositories extract
  content faster than seeking and reading content from another tree,
  especially in cold-cache situations. (John Arbash Meinel, #607298)

Documentation
*************
* A beta version of the documentation is now available in GNU TexInfo
  format, used by emacs and the standalone ``info`` reader.
  (Vincent Ladeuil, #219334)
