:2.4.2: 2011-10-27

This is a bugfix release. Most of the bugs dealt with portability
issues. Upgrading is recommended for all users of earlier 2.4 releases.

External Compatibility Breaks
*****************************

None.

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

None.

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

* Fixed a bug where ``bzr tags -r x..y`` loaded the branch history once for
  every revision in the range; it's now much faster. (Vincent Ladeuil, #857335)

Bug Fixes
*********

* Fixed an infinite loop when creating a repo at the root of the filesystem, 
  i.e. "/", due to posixpath.normpath() not collapsing 2 leading \ 
slashes into 
  one, thus respecting the POSIX standard, but making relpath() loop infinitely.
  (Florian Vichot, #861008)

* Fixed loading of external merge tools from config to properly decode
  command-lines which contain embedded quotes. (Gordon Tyler, #828803)

* Include declaration of 'changed' to avoid an UnboundLocalError in dirstate
  pyrex code with new Cython versions. (Denys Duchier, #837221)

* Prevent several kinds of OverflowError and other fallout from failing to fit
  stat fields into four bytes in dirstate pack_stat implementations.
  (Martin Packman, #683191 #706957)

* Return early from create_delta_index_from_delta given tiny inputs. This
  avoids raising a spurious MemoryError on certain platforms such as AIX.
  (John Arbash Meinel, #856731)
  
Documentation
*************

* Corrected documentation for ``bzr serve`` in the Admin Guide.
  (Morten Bøgeskov, Martin Pool, #832576)

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

None.

Internals
*********

No changes.

Testing
*******

* Accept both old and new style testtools output in selftest tests.
  (Jelmer Vernooij, Martin Packman, #815423)

* Fix the race for TestingThreadingTCPServer in
  test_server_crash_while_responding. (Vincent Ladeuil, #869366)

* Really corrupt the pack file without depending on a special length or value.
  (Vincent Ladeuil, #807032)
