I just noticed on one page of the Python website that it said: "We are pleased to announce the release of Python 2.4.3 (final), a bugfix release of Python 2.4, on March 29, 2006."
Yet elsewhere it refers to it as a "release candidate" and still refers to 2.4.2 as the "current production version". -- http://mail.python.org/mailman/listinfo/python-list
