The answer to this, of course, is "it depends".  Do you require 
particular third-party extensions, and if so, are they available for 
2.3?  Is there any critical applications that you're running that 
break under some of the backwards-incompatibilities introduced in 2.3? 
(This isn't likely, but it is possible.)  Presuming that neither of 
these issues are a problem, then there's little reason to use any 
"older" versions of Python.  If either of these are a problem, then 
you'll want to install (the latest bugfixed release of) 2.2 -- IIRC, 
PythonLabs has declared that they will keep supporting 2.2 for quite 
some time, whereas they've dropped direct support of 2.0 and 2.1, and 
almost every third-party extension packages that you'd be interested 
in will already be available for it.  (Note, however, that there's 
some backwards-incompatibilities introduced between 1.6 and 2.2, so 
you'll want to test everything right away regardless of whether you 
choose 2.2 or 2.3 ...)

2.2 is the more conservative choice, but 2.3 should be stable and 
ready for production use as well.
