I'd like to add my vote to retaining Undo, I think it's a crucial
feature. Changing the API is not a problem, and changing the UI could
probably be an improvement. I use it all the time, especially when
fiddling with customer datatabases for upgrades or bugfixes.

Plone users tend to use Undo quite a lot. If you accidentally delete

Are you asking at the ZODB level, or at a higher level, such as Zope?

Speaking from the Zope2/Plone crowd: I'm using it during development
with a local file storage at times.
In a real ZEO production setup, undo in Plone most of the tim

We use undo from time to time in a zeo setup. When it works it can be
a life saver! :) If it goes away I guess it wouldn't be the end of
the world though.

Undo is causing some problems. For storages that support undo *and*
work with ZEO, I'd like to add a new method, transaction_oids, that returns the
oids modified by a transaction. Currently AFAIK, there are only 2
