I can't point at any one killer feature here:
http://docs.python.org/whatsnew/2.6.html

There are assorted little things now where we have had to
add Python 2.5 specific code or fallbacks (e.g. OrderedDict).

The main other benefit is 2.6 adds a number of new features
from Python 3, which should make supporting Python 2 and 3
a little easier (e.g. byte literals).
