==================
- Raise more "Pythonic" errors from ``__setitem__``, losing the dependency
on ``zope.exceptions``:
o ``zope.exceptions.DuplicationError`` -> ``KeyError``
o ``zope.exceptions.UserError`` -> ``ValueError``
- Move import of ``IBroken`` interface to use new ``zope.broken``
package, which has no dependencies beyond ``zope.interface``.
- Make ``test`` part pull in the extra test requirements of this package.
- Split the ``z3c.recipe.compattest`` configuration out into a new file,
``compat.cfg``, to reduce the burden of doing standard unit tests.
- Strip out bogus develop eggs from ``buildout.cfg``.
