==================
- Remove backward-compatibility imports:
- ``zope.copy.clone`` (aliased as ``zope.location.pickling.locationCopy``)
- ``zope.copy.CopyPersistent`` (aliased as
``zope.location.pickling.CopyPersistent``).
- ``zope.site.interfaces.IPossibleSite`` (aliased as
``zope.location.interfaces.IPossibleSite``).
- Add Python 3.2 support.
- Make ``zope.component`` dependency optional. Use the ``component`` extra
to force its installation (or just require it directly). If
``zope.component`` is not present, this package defines the ``ISite``
interface itself, and omits adapter registrations from its ZCML.
- Add support for PyPy.
- Add support for continuous integration using ``tox`` and ``jenkins``.
- Bring unit test coverage to 100%.
- 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.component.adapts`` usage with equivalent
``zope.component.adapter`` decorator.
- Replace deprecated ``zope.interface.implements`` usage with equivalent
``zope.interface.implementer`` decorator.
- Drop support for Python 2.4 and 2.5.
