Another data point: I write some Python code in my work and some for
hobby/private use, and I am very happy with 2.3.  List comprehensions
(or whatever they are called) and generators are the most recent
features I would hate living without.

OP: keep in mind that your users do not see any gain from you using
2.5. All they see is something that makes your software harder to
install. At some point you can dismiss them as living in the Stone Age,
but the Stone Age is currently 2.1 or something. Maybe 2.2 is, too.
