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)
