The Bazaar team is happy to announce availability of a new releases of
the bzr adaptive version control system. Bazaar is part of the GNU
system <http://gnu.org/>.

The third release of Bazaar 2.0 (2.0.3) has a small handful of bugfixes.
As expected, this has no internal or external compatibility changes
versus 2.0.2 (or 2.0.0).

The fourth beta release in the 2.1 series brings with it a significant
number of bugfixes (~20). The test suite is once again (finally) "green"
on Windows, and should remain that way for future releases. There are a
few performance related updates (faster upgrade and log), and several UI
tweaks. There has also been a significant number of tweaks to the
runtime documentation. 2.1.0b4 include everything from the 2.0.3 release.

It is expected that the next release in the 2.1 series will be 2.1.0rc1,
which means it will then enter into its stable bugfix-only phase (and
2.2.0b1 will be opened for development.)

Thanks to everyone who contributed patches, suggestions, and feedback.

Both the source and platform specific binaries can be downloaded from
  https://launchpad.net/bzr/2.0/2.0.3

As always, all releases are available from

bzr 2.1.0b4
###########

:Codename: san francisco airport
:2.1.0b4: 2009-12-14

The fourth beta release in the 2.1 series brings with it a significant
number of bugfixes (~20). The test suite is once again (finally)
"green" on Windows, and should remain that way for future releases.
There are a few performance related updates (faster upgrade and log),
and several UI tweaks. There has also been a significant number of
tweaks to the runtime documentation. 2.1.0b4 include everything from
the 2.0.3 release.


Compatibility Breaks
********************

* The BZR_SSH environmental variable may now be set to the path of a
  secure shell client. If currently set to the value ``ssh`` it will
  now guess the vendor of the program with that name, to restore the
  old behaviour that indicated the SSH Corporation client use
  ``sshcorp`` instead as the magic string.
  (Martin <address@hidden>, #176292)

New Features
************

* ``bzr commit`` now has a ``--commit-time`` option.
  (Alexander Sack, #459276)

* ``-Dhpss`` now increases logging done when run on the bzr server,
  similarly to how it works on the client. (John Arbash Meinel)

* New option ``bzr unshelve --keep`` applies the changes and leaves
  them on the shelf.  (Martin Pool, Oscar Fuentes, #492091)

* The ``BZR_COLUMNS`` envrionment variable can be set to force bzr to
  respect a given terminal width. This can be useful when output is
  redirected or in obscure cases where the default value is not
  appropriate. Pagers can use it to get a better control of the line
  lengths.  (Vincent Ladeuil)

Bug Fixes
*********

* After renaming a file, the dirstate could accidentally reference
  ``source\\path`` rather than ``source/path`` on Windows. This might
  be a source of some dirstate-related failures. (John Arbash Meinel)

* ``bzr commit`` now detects commit messages that looks like file
  names and issues a warning.  (Gioele Barabucci, #73073)

* ``bzr ignore /`` no longer causes an IndexError.
  (Gorder Tyler, #456036)

* ``bzr log -n0 -rN`` should not return revisions beyond its merged
  revisions.  (#325618, #484109, Marius Kruger)

* ``bzr merge --weave`` and ``--lca`` will now create ``.BASE`` files
  for files with conflicts (similar to ``--merge3``). The contents of the
  file is a synthesis of all bases used for the merge.
  (John Arbash Meinel, #40412)

* ``bzr mv --quiet`` really is quiet now.  (Gordon Tyler, #271790)

* ``bzr serve`` is more clear about the risk of supplying
  --allow-writes.  (Robert Collins, #84659)

* ``bzr serve --quiet`` really is quiet now.  (Gordon Tyler, #252834)

* Fix bug with redirected URLs over authenticated HTTP.
  (Glen Mailer, Neil Martinsen-Burrell, Vincent Ladeuil, #395714)

* Interactive merge doesn't leave branch locks behind.
  (Aaron Bentley)

* Lots of bugfixes for the test suite on Windows. We should once again
  have a test suite with no failures on Windows. (John Arbash Meinel)

* ``osutils.terminal_width()`` obeys the BZR_COLUMNS environment
  variable but returns None if the terminal is not a tty (when output
  is redirected for example). Also fixes its usage under OSes that
  doesn't provide termios.TIOCGWINSZ. Make sure the corresponding
  tests runs on windows too.
  (Joke de Buhr, Vincent Ladeuil, #353370, #62539)
  (John Arbash Meinel, Vincent Ladeuil, #492561)

* Terminate ssh subprocesses when no references to them remain, fixing
  subprocess and file descriptor leaks.  (Andrew Bennetts, #426662)

* The ``--hardlink`` option of ``bzr branch`` and ``bzr checkout`` now
  works for 2a format trees.  Only files unaffected by content filters
  will be hardlinked.  (Andrew Bennetts, #408193)

* The new glob expansion on Windows would replace all ``\`` characters
  with ``/`` even if it there wasn't a glob to expand, the arg was
  quoted, etc. Now only change slashes if there is something being
  glob expanded.  (John Arbash Meinel, #485771)

* Use our faster ``KnownGraph.heads()`` functionality when computing
  the new rich-root heads. This can cut a conversion time in half
  (mysql from 13.5h => 6.2h) (John Arbash Meinel, #487632)

* When launching a external diff tool via bzr diff --using, temporary
  files are no longer created, rather, the path to the file in the
  working tree is passed to the external diff tool. This allows the
  file to be edited if the diff tool provides for this.
  (Gary van der Merwe, #490738)

* The launchpad-open command can now be used from a subdirectory of a
  branch, not just from the root of the branch.  (Neil
  Martinsen-Burrell, #489102)


Improvements
************

* ``bzr log`` is now faster. (Ian Clatworthy)

* ``bzr update`` provides feedback on which branch it is up to date
  with.  (Neil Martinsen-Burrell)

* ``bzr upgrade`` from pre-2a to 2a can be significantly faster (4x).
  For details see the xml8 patch and heads() improvements.
  (John Arbash Meinel)

* ``bzrlib.urlutils.local_path_from_url`` now accepts
  'file://localhost/' as well as 'file:///' URLs on POSIX.  (Michael
  Hudson)

* The progress bar now shows only a spinner and per-operation counts,
  not an overall progress bar.  The previous bar was often not
  correlated with real overall operation progress, either because the
  operations take nonlinear time, or because at the start of the
  operation Bazaar couldn't estimate how much work there was to do.
  (Martin Pool)

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

* Lots of documentation tweaks for inline help topics and command help
  information.

API Changes
***********

* ``bzrlib.textui`` (vestigial module) removed.  (Martin Pool)

Internals
*********

* New test Feature: ``ModuleAvailableFeature``. It is designed to make
  it easier to handle what tests you want to run based on what modules
  can be imported. (Rather than lots of custom-implemented features
  that were basically copy-and-pasted.) (John Arbash Meinel)

* ``osutils.timer_func()`` can be used to get either ``time.time()``
  or ``time.clock()`` when you want to do performance timing.
  ``time.time()`` is limited to 15ms resolution on Windows, but
  ``time.clock()`` gives CPU and not wall-clock time on other
  platforms.  (John Arbash Meinel)

* Several code paths that were calling ``Transport.get().read()`` have
  been changed to the equalivent ``Transport.get_bytes()``. The main
  difference is that the latter will explicitly call ``file.close()``,
  rather than expecting the garbage collector to handle it. This helps
  with some race conditions on Windows during the test suite and sftp
  tests. (John Arbash Meinel)

Testing
*******

* TestCaseWithMemoryTransport no longer sets $HOME and $BZR_HOME to
  unicode strings. (Michael Hudson, #464174)


bzr 2.0.3
#########

:Codename: little italy
:2.0.3: 2009-12-14

The third stable release of Bazaar has a small handful of bugfixes. As
expected, this has no internal or external compatibility changes
versus 2.0.2 (or 2.0.0).


Bug Fixes
*********

* ``bzr push --use-existing-dir`` no longer crashes if the directory
  exists but contains an invalid ``.bzr`` directory.  (Andrew
  Bennetts, #423563)

* Content filters are now applied correctly after pull, merge and
  switch. (Ian Clatworthy, #385879)

* Fix a potential segfault in the groupcompress hash map handling
  code.  When inserting new entries, if the final hash bucket was
  empty, we could end up trying to access if ``(last_entry+1)->ptr ==
  NULL``.  (John Arbash Meinel, #490228)

* Improve "Binary files differ" hunk handling.
  (Aaron Bentley, #436325)
