Well, this depends on what release ships when. We made a decision not to  
ship Zope 2.8.0 as the standard in the installers when shipping Plone 2.1  
- and that turned out to be a good choice, based on the number of problems  
it had.

I can guarantee you that Plone 2.5 will not ship with a Zope 2.9.0. A Zope  
2.9.(1|2|3) might be possible, but there's no way we are shipping a .0  
release of Zope with Plone. Once burnt, twice shy. :)

What we ship in installers is one thing, what we personally use and  
recommend is another. The installers will always be more conservative when  
choosing versions.

Most developers using Plone 2.1 uses it with Zope 2.8, but the installers  
ship with Zope 2.7, and it turned out to be a good decision in hindsight.
