2.2 -> 2.5 is a minor step, the 2.2-code should in general work out on 2.5 without problems. 2.6 -> 3.0 will be a major step, and code written for 2.6 or earlier will in general not run on python 3.0. Hopefully this issue can be partially solved by automatic code converting. -- Tobias Brox, 69°42'N, 18°57'E -- http://mail.python.org/mailman/listinfo/python-list
