====================
- Add support for Python 3.3.
- Make ``Folder`` class inherit from ``BTreeContainer`` class, so that the
IContainer interface does not need to be re-implemented. Added a ``data``
attribute for BBB.
- 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.
- Send ``IContainerModifiedEvent`` *after* the container is modified
(LP705600).
- Preserve the original exception traceback in
``OrderedContainer.__setitem__``.
- Handle Broken Objects more gracefully
- Fix a bug that made it impossible to store None values in containers
(LP1070719).
