- Ensure that the ``SimpleKeyReference`` implementation (used for testing) also implements rich comparison properly.
4.0.0a1
====================
- Add support for Python 3.3.
- Replace deprecated ``zope.component.adapts`` usage with equivalent ``zope.component.adapter`` decorator.
- Replace deprecated ``zope.interface.implements`` usage with equivalent ``zope.interface.implementer`` decorator.
- Drop support for Python 2.4 and 2.5.
3.6.4
==================
- Fix tests broken by removal of ``zope.testing`` from test dependencies: avoid the ``ZODB3`` module that needs it.
3.6.3
==================
- Prefer the standard libraries doctest module to the one from ``zope.testing``.
3.6.2
==================
- Make the tests pass with ZODB3.9, which changed the repr() of the persistent classes.
3.6.1
==================
- Load keyreferences, pickled by old zope.app.keyreference even if its not installed anymore (so don't break if one updates a project that don't directly depends on zope.app.keyreference).
