------------------
- Add support for PyPy.
N.B.: the C extension is *not* built under PyPy.
- Add a pure-Python reference / fallback implementations of
``zope.proxy.ProxyBase`` and the proxy module API functions.
N.B.: the pure-Python proxy implements all regular features of
``ProxyBase``; however, it does not exclude access to the wrapped object
in the same way that the C version does. If you need that information
hiding (e.g., to implement security sandboxing), you still need to use
the C version.
- Add support for continuous integration using ``tox`` and ``jenkins``.
- 100% unit test coverage.
- Add Sphinx documentation: moved doctest examples to API reference.
- Add 'setup.py docs' alias (installs ``Sphinx`` and dependencies).
- Add 'setup.py dev' alias (runs ``setup.py develop`` plus installs
``nose`` and ``coverage``).
- Replace deprecated ``zope.interface.implements`` usage with equivalent
``zope.interface.implementer`` decorator.
- Drop support for Python 2.4 and 2.5.
- Add Python 3.2 support.
