Adjust the Zope 3.5 documentation to point to the Zope Toolkit instead. Also use Zope 2 instead of Zope2 throughout.

o Preserve response class as well.

Merged the two versions files into one. There's currently no maintained Zope Toolkit KGS we could reuse.

Added automatic inline migration for databases created with older Zope versions. The `Versions` screen from the `Control_Panel` is now automatically removed on Zope startup.

Removed more unused code of the versions support feature including the Globals.VersionNameName constant.

Make the set_attributes and set_schema options to <class ...><require ... /></class> issue a warning rather than throw an exception. Whilst the concept doesn't make much sense in Zope 2, it's desirable to be able to re-use existing packages that do declare such protection

add "python" option to zope.conf schema allowing for a python binary to be specified, allowed a Zope instance to run from any buildout with the appropriate eggs.
