There are indeed some issues to be sorted out with Zope 2.9 (Windows installer,
premature zLOG deprecation, etc.), all of which aren't too big anymore, though.
I think we can and should have a 2.9.1 bugfix release relatively soon.

By looking at http://plone.org/products/plone/roadmap, Plone 2.5 will be out by
2006/05/08. By then Zope 2.9 can be considered stable and shippable I would
say. Heck, by that time we'll already have a 2.10beta if I'm not mistaken.

I can understand that reasoning. Fortunately, time-based releases will let us
schedule these things in advance. E.g. by looking at the Plone 3.0 roadmap we
can say that it will be relatively safe for it to depend and ship with Zope
2.10, coming out more than 3 months after the Zope 2.10 final release.
