Yes, my needs are similar. Ive discussed this capabaility with Jim Fulton=
=20
before, and he argues that this type of history should be retained at=20
application level, not in the ZODB. I think this capability will be usefu=
l=20
for proving that there hasnt been a change, in cases where changes are=20
exceptional. If you are wanting to track many changes then Jims approach =
is=20
better.

Do you really mean undo?

Supporting a longer-than-normal history for undo means retaining extra=20
revisions of other objects that happen to be modified in the same=20
transaction. I dont think you or I need that. Right?
