Yep, the new Plone 4.0 (to be released sometime this year) is planned to
be a new more stable stepping stone to the Plone trunk work that is
going on for a while.

We have been talking about using Zope 2.11 for that release so far,
since Zope 2.12 is quite invasive. But I think that's a decision that is
still to be made and we can go with 2.12 for the new Plone 4.

If there are good reasons for the CMF developers to switch to an
exclusive Zope 2.12 platform, Plone can deal with that. If there's no
real reason except "it's newer" and the cost of being compatible with
both 2.11 and 2.12 isn't too high, targeting both Zope versions might be

Why doesn't that generate test failures? We are running nightly tests
testing CMF trunk with Zope 2.10, 2.11 and 2.12.
