==================
- Add support for Python 3.4, 3.5, 3.6 and PyPy.
- The long-deprecated layer configuration was removed. It was only
ever available if the ``deprecatedlayers`` ZCML feature was installed.
- Modernize some of the templates. ``zope.app.apidoc`` can now be used
with Chameleon 3.2 via z3c.pt and z3c.ptcompat.
- Declared install dependency on ``zope.app.exception``.
- Docstrings are treated as UTF-8 on Python 2.
- Handle keyword only arguments and annotations in function signatures
on Python 3.
- Change the default documentation format to ``restructuredtext`` for
modules that do not specify a ``__docformat__``. Previously it was
``structuredtext`` (STX).
