==================
- Add support for Python 3.4, 3.5 and 3.6 and PyPy.
- Remove support for Python 2.6 and 3.3.
- Change the default source suffix from ``.txt`` to ``.rst``. You can
override this using the new ``extra-conf`` setting.
- Add the ability to specify arbitrary configuration in the
``extra-conf`` setting. This is useful for things like configuring
extensions, overriding the defaults set by this recipe, and
configuring a sphinx theme.
- Stop forcing a value of ``default.css`` for ``html_style`` even when
the ``default.css`` setting is configured to an empty value. This
makes it possible to use ``html_theme`` to set a sphinx theme, and
it properly lets the default Sphinx theme be used (by setting both
``default.css`` and ``layout.html`` to empty values).
- Ignore bad eggs in the documentation working set. Previously they
would raise internal errors without any explanation. Now, they log a
warning pinpointing the bad egg. Fixes `issue 6
<https://github.com/zopefoundation/z3c.recipe.sphinxdoc/issues/6>`_.
