==================
- Remove ``zope.container`` dependency, as contained principals didn't make any
sense, since PrincipalRegistry never provided IContainer. Also, zope.container
pulls a number dependencies, that are not needed for non-persistent principal
registry (like, ZCML, for example).
Set ``__name__`` and ``__parent__`` by hand to provide some backward-compatibility and
to save a pointer to registry from principal objects.
- Initial release. This package was split from zope.app.security as a part
of the refactoring process to provide global principal registry without extra
dependencies.
