Python 1.5.2 is still in active use. Some of the extension
writers simply can't drop 1.5.2 because of an active user
base still working with it (either because they are using
commercial products built on top of 1.5.2 or because
they like the speed... Python 2.x is slower than 1.5.2, or
because their books still reference the old version).
Python's release schedule has changed dramatically over
the last few years -- I would expect that the Python 2.0
user base will also last a few more years.
