value "enterprise ready" meaning they run ancient stuff should be perfectly
fine with numpy 1.4 + scipy 0.8 for a long time from now. And otherwise they
can upgrade python itself quite easily. 2.4 doesn't even get security
updates anymore.

We now support python 2.4-2.6, for the next versions we'll add 2.7, 3.1 and
3.2. Supporting more versions has a cost. And it's clear that the amount of
people running 2.4 from svn is at or close to zero, because recent syntax
errors for 2.4 have gone unnoticed for a long period. I think it's about
time to drop 2.4.
