+1 from me too. I too think we might as well go from 2.4 to 2.6, since there are relatively few live platforms that only have 2.5. bzr 2.3 will keep supporting python2.4 and getting at least bug fixes through late 2011, and critical fixes even beyond that. We should make sure people get a clean message if they do try to run it on 2.4. Martin
