[Zope3-Users] Re: Zope3 still not compatible with Python2.5

[Philipp von Weitershausen]

This is a rather confusing post. I'm not sure what you're trying to say 
with it.

Is Python 2.5 officially supported? No. We never said it was.

Does Zope 3.4 actually work on Python 2.5.1? Yes, it works just fine for 
me and others. For example, Grok runs on Python 2.5.1 no problem [1].

Is this a platform issue? Maybe, but your post isn't giving *any* useful 
information for tracking this down. All you're basically saying is that 
you were "experimenting with several things all at once" and that that 
was a bad idea. You certainly got that right.

I hope the rest isn't taken for FUD. I certainly encourage people to try 
out Zope 3.4 on Python 2.5 and report any problems *properly* so that we 
can chase down the bugs.
