Zope 2.10 contains Zope 3.3 which most likely doesn't work on Python 
2.5. Nobody has bothered to take a look, really, since it's ages old.

Zope 2.11 contains the Zope 3.4 KGS, as far as I'm aware. If the 3.4 KGS 
refers to the latest bugfix releases of all packages, then it works on 
Python 2.5.

Superficially, many Zope 3 packages also work on Python 2.6 (e.g. Grok 
runs), but a closer look reveals various test failures.


IMHO we shouldn't worry about 2.10 and 2.11 and just care about 2.12 at 
this point. By now it should work with Python 2.5, right? Let's release 
it soonish. Not only will it bring Python 2.5 compatibility but it also 
gets rid of Acquisition-wrapped views and introduces (optional) 
__parent__ pointers. Three years after having started the 
implementation, I think it's time to get it out there :)
