==================
- Add support for Python 3.5 and 3.6.
- Drop support for Python 2.6, 3.2 and 3.3.
- Certain internal test support objects in the ``tests`` package were
removed or modified.
- The ``TraversableModuleImporter`` properly turns ``ImportError``
into ``TraversalError``. Previously it was catching ``KeyError``,
which cannot be raised.
- Reach 100% code coverage and maintain it through automated testing.
