Unless I am mistaken, Zope 2.5.1, 2.6.0, 2.6.1 all *require* Python 2.1.3 and will not work with Python 2.2 and later.
Do we have a problem?
No, because
* Python 2.1.3 runs very reliably. We do not need maintenance for it.
* Zope 2.6 does run with Python 2.x (for "x >= 2")
Really? Is that official? Because actually, there's a lot of 3rd party modules that require 2.2+ (the first that comes to mind is the "constraints" module), that I would like to start using. So being forced to stick with 2.1 has been a bit annoying (have to maintain two versions of Python, can't integrate some packages with Zope, etc).
If it works, thanks for the info. I'll definitely try it out.
I assume it's a no-brainer that Zope3 will work with later Python versions, of course.
There's an opinion from one person (from russian zopylist) who had big practice in connecting Zope & Python222: The workability of Zope & Python222 is finished when you try to inherit from object & extension class at once, as well as other analog innovations; they're conflicting with ExtensionClass. If he's reading the list he would probably explain it in more details.. WBR, Serge
