Hi Tim,

thanks to Hanno's clarifications on IRC last week let me point out that we  
are talking about the roadmap for the ZTK 1.1.

Support for Python 2.4 *will* be dropped this year. Python 2.5 is likely  
to survive longer not least because it is the supported version on the  
current version of Debian, although it's looking likely that there will be  
a new release (Debian 6.0 aka Squeeze) in the not too distant future. And  
I guess that GAE is still tied to 2.5? Beyond that, however, I think it's  
only reasonable to start looking at the migration towards a codebase that  
runs on Python 3.x and that may, at some point, mandate dropping support  
for Python 2.5. This especially in light of the fact that Python 2.5  
itself is in maintenance mode.

At the moment I think any incomaptabilities are related to tests and  

However, this is all in the future and subject, no doubt, to review.
