[Zope] ZEO manageUndo not working - DisconnectedError

[Sebastian Tänzer]

After further testing I was able to sort this one out by downgrading ZopeUndo to 2.12.0 (pip install ZopeUndo==2.12.0 --force —upgrade).
PyPi only said 4.0 brought Py3 compability. Should I expect any problems using ZopeUndo 2.12 + ZEO/ZODB4/ZODB3 with their latest versions?

Best, Sebastian
