16
* An API break has been made to the lock_write method of ``Branch`` and
 
17
  ``Repository`` objects; they now return ``branch.BranchWriteLockResult``
 
18
  and ``repository.RepositoryWriteLockResult`` objects. This makes
 
19
  changing the API in future easier and permits some cleaner calling code.
 
20
  The lock_read method has also changed from having no defined return
 
21
  value to returning ``LogicalLockResult`` objects.

107
* Lock methods on ``Tree``, ``Branch`` and ``Repository`` are now
 
108
  expected to return an object which can be used to unlock them. This reduces
 
109
  duplicate code when using cleanups. The previous 'tokens's returned by
 
110
  ``Branch.lock_write`` and ``Repository.lock_write`` are now attributes
 
111
  on the result of the lock_write. ``repository.RepositoryWriteLockResult``
 
112
  and ``branch.BranchWriteLockResult`` document this. (Robert Collins)
