At my work, I'm on RHEL5 and RHEL6. So I'm currently supporting python-2.4
and python-2.6. We're up to 75% RHEL6 (though, not the machines where most
of our deployed, custom written apps are running) so I shouldn't have to
support python-2.4 for much longer.

As part of work, I package for EPEL5 (addon packages for RHEL5). Sometimes
we need a new version of a package or a new package for RHEL5 and thus need
to have python-2.4 compatible versions of the package and any of its
When I no longer need to maintain python-2.4 stuff for work, I'm hoping to
not have to do quite so much of this but sometimes I know I'll still get
requests to update an existing package to fix a bug or fix a feature and
that will require updates of dependent libraries. I'll still be stuck
looking for python-2.4 compatible versions of all of these :-(

I agree that libraries have a need to go farther back than applications.
I have one library that I support on python-2.3 (for RHEL4... I'm counting
down the months on that one :-). Every other library I maintain, I make sure
I support at least python-2.4.
Application-wise, I currently have to support python-2.4+ but given that
Linux distros seem to all have some version out that supports at least
python-2.6, I don't think I'll be developing any applications that
intentionally support less than that once I get moved away from RHEL-5 at my
