* Issue 313: Removed built-in support for subversion. Projects wishing to
retain support for subversion will need to use a third party library. The
extant implementation is being ported to :pypi:`setuptools_svn`.
* Issue 315: Updated setuptools to hide its own loaded modules during
installation of another package. This change will enable setuptools to
upgrade (or downgrade) itself even when its own metadata and implementation
change.
