Changes

A warning is now displayed when opening working trees in older formats, to encourage people to upgrade to WorkingTreeFormat4. (Martin Pool)

HTTP redirections are now taken into account when a branch (or a bundle) is accessed for the first time. A message is issued at each redirection to inform the user. In the past, http redirections were silently followed for each request which significantly degraded the performances. The http redirections are not followed anymore by default, instead a RedirectRequested exception is raised. For bzrlib users needing to follow http redirections anyway, bzrlib.transport.do_catching_redirections provide an easy transition path. (vila)

Added ReadLock.temporary_write_lock() to allow upgrading an OS read lock to an OS write lock. Linux can do this without unlocking, Win32 needs to unlock in between. (John Arbash Meinel)
New parameter recommend_upgrade to BzrDir.open_workingtree to silence (when false) warnings about opening old formats. (Martin Pool)
Fix minor performance regression with bzr-0.15 on pre-dirstate trees. (We were reading the working inventory too many times). (John Arbash Meinel)
Remove Branch.get_transaction() in favour of a simple cache of revision_history. Branch subclasses should override _gen_revision_history rather than revision_history to make use of this cache, and call _clear_revision_history_cache and _cache_revision_history at appropriate times. (Andrew Bennetts)

Take smtp_server from user config into account. (vila, #92195)
Restore Unicode filename handling for versioned and unversioned files. (John Arbash Meinel, #92608)
Don’t fail during bzr commit if a file is marked removed, and the containing directory is auto-removed. (John Arbash Meinel, #93681)
bzr status FILENAME failed on Windows because of an uncommon errno. (ERROR_DIRECTORY == 267 != ENOTDIR). (Wouter van Heyst, John Arbash Meinel, #90819)
bzr checkout source should create a local branch in the same format as source. (John Arbash Meinel, #93854)
bzr commit with a kind change was failing to update the last-changed-revision for directories. The InventoryDirectory._unchanged only looked at the parent_id and name, ignoring the fact that the kind could have changed, too. (John Arbash Meinel, #90111)
bzr mv dir/subdir other was incorrectly updating files inside the directory. So that there was a chance it would break commit, etc. (John Arbash Meinel, #94037)
Correctly handles mutiple permanent http redirections. (vila, #88780)
