Re: ZopeUndo.Prefix is still used

Hi again.

Looking into this a bit more, I changed the Zope2 code on master and
dropped the ZopeUndo dependency.

Undo management in Zope2 is now available in its ZMI control panel on
each configured database object, instead of contextually on ZMI folders.

Hope this helps,
Hanno
