I can't remember any decision to move the authoritative copy of
Products.GenericSetup to the servers of GitHub Inc.
So either the place for making authoritative decisions about
Products.GenericSetup has also moved somewhere else or the canonical
repository is still svn.zope.org .
Why was https://pypi.python.org/pypi/Products.GenericSetup/1.7.5
released from a different repository and why was this change made:
Zope-CMF maillist - Zope-CMF@zope.org
See https://bugs.launchpad.net/zope-cmf/ for bug reports and feature requests
