Upgrade or not ??

Of course.

Carrots and sticks.  And why wouldn't you?  It's free!

More than a year passed between 1.5.1 and 1.5.2, spanning hundreds of little
improvements and bugfixes, along with a few major ones.  So, e.g., if you
find a bug in 1.5.1, the response will be (http://www.python.org/1.5/):

    Forget about reporting a bug until you've confirmed that the bug
    still occurs in the 1.5.2 release

IOW, 1.5.1 is no longer supported.  And while the dozen <wink> lines of code
you've already written for 1.5.1 are very likely to work fine under 1.5.2,
as time goes on more & more new useful modules and code snippets are likely
to require new-in-1.5.2 features.

Not a Tk guy, so I'll skip to the end:

If you can get a prototype done in Python 10x faster than in anything else,
and get the first crucial rounds of redesign done at that speed too, you win
big overall even if you do end up recoding the refined design in some other
language.

IOW, be realistic here:  you lose the work done for a prototype no matter
what language you write it in.  That's why they call it a prototype instead
of a product <wink>.
