bzr 2.0.1
#########

:Codename: Stability First
:2.0.1: 2009-10-14

The first of our new ongoing bugfix-only stable releases has arrived. It
includes a collection of 12 bugfixes applied to bzr 2.0.0, but does not
include any of the feature development in the 2.1.0 series.

Bug Fixes
*********

* ``bzr add`` in a tree that has files with ``\r`` or ``\n`` in the
  filename will issue a warning and skip over those files.
  (Robert Collins, #3918)

* bzr will attempt to authenticate with SSH servers that support
  ``keyboard-interactive`` auth but not ``password`` auth when using
  Paramiko.  (Andrew Bennetts, #433846)

* Fixed fetches from a stacked branch on a smart server that were failing
  with some combinations of remote and local formats.  This was causing
  "unknown object type identifier 60" errors.  (Andrew Bennetts, #427736)

* Fixed ``ObjectNotLocked`` errors when doing some log and diff operations
  on branches via a smart server.  (Andrew Bennetts, #389413)

* Handle things like ``bzr add foo`` and ``bzr rm foo`` when the tree is
  at the root of a drive. ``osutils._cicp_canonical_relpath`` always
  assumed that ``abspath()`` returned a path that did not have a trailing
  ``/``, but that is not true when working at the root of the filesystem.
  (John Arbash Meinel, Jason Spashett, #322807)

* Hide deprecation warnings for 'final' releases for python2.6.
  (John Arbash Meinel, #440062)

* Improve the time for ``bzr log DIR`` for 2a format repositories.
  We had been using the same code path as for <2a formats, which required
  iterating over all objects in all revisions.
  (John Arbash Meinel, #374730)

* Make sure that we unlock the tree if we fail to create a TreeTransform
  object when doing a merge, and there is limbo, or pending-deletions
  directory.  (Gary van der Merwe, #427773)

* Occasional IndexError on renamed files have been fixed. Operations that
  set a full inventory in the working tree will now go via the
  apply_inventory_delta code path which is simpler and easier to
  understand than dirstates set_state_from_inventory method. This may
  have a small performance impact on operations built on _write_inventory,
  but such operations are already doing full tree scans, so no radical
  performance change should be observed. (Robert Collins, #403322)

* Retrieving file text or mtime from a _PreviewTree has good performance when
  there are many changes.  (Aaron Bentley)

* The CHK index pages now use an unlimited cache size. With a limited
  cache and a large project, the random access of chk pages could cause us
  to download the entire cix file many times.
  (John Arbash Meinel, #402623)

* When a file kind becomes unversionable after being added, a sensible
  error will be shown instead of a traceback. (Robert Collins, #438569)

Documentation
*************

* Improved README. (Ian Clatworthy)

* Improved upgrade documentation for Launchpad branches.
