One of the main reasons to keep 2.5 support was for the App Engine, but I believe it now supports 2.7. I don't know of any major features from 2.6 that we're missing. I guess you could check the compatibility file to get an idea. I know it's not even close to the way it was with 2.4. I couldn't wait to drop support for that. Now 2.7 on the other hand added a lot of cool features, like ordered dicts, set literals, dict and set comprehensions, and the argparse module. But dropping 2.6 support is still probably out of the question.
The only new syntax in 2.6 as far as I can tell is "except Exception as e" (with statements can be enabled in 2.5 with "from __future__ import with_statement"). New non-syntax features can be added manually to the compatibility file.
