==================
- Added ``zope.testing.setupstack.mock`` as a convenience function for
setting up mocks in tests. (The Python ``mock`` package must be in
the path for this to work. The excellent ``mock`` package isn't a
dependency of ``zope.testing``.)
- Added the base class ``zope.testing.setupstack.TestCase`` to make it
much easier to use ``zope.testing.setupstack`` in ``unittest`` test
cases.
