- Add support for Python 3.7 and drop support for Python 3.3.
- Fix a DeprecationWarning from ``zope.annotation.attribute``. See `issue 16 <https://github.com/zopefoundation/zope.annotation/issues/16>`_.
4.6.0
==================
- Make ``AttributeAnnotations`` have a ``__parent__``. The ``__parent__`` is the object that it stores ``__annotations__`` on. This is a convenience for upwards traversal as used by things like ``zope.keyreference``. See https://github.com/zopefoundation/zope.annotation/issues/11
