+2.12.1 (2009-04-15)
 -------------------
 
 - Update for iteration proxying: The proxy for `__iter__` must not rely on the
   object to have an `__iter__` itself, but also support fall-back iteration via
   `__getitem__` (this fixes https://bugs.launchpad.net/zope2/+bug/360761).

+2.12 (2009-01-25)

 - Release as separate package.
