Mark Sapiro wrote this message describing the unintended breakage in Mailman 2.1.9: http://mail.python.org/pipermail/mailman-users/2006-September/ 053290.html So the big difference between 2.1 and 2.2 was the unification of classes and types, which also changed the built-in factory functions like int() and str() to be types instead of functions. No one should use Python 2.2 for anything really. It was a fairly radical release and many of the new features didn't stabilize until Python 2.3. The main reason I want to drop Python 2.1 and 2.2 is that I simply can't build them on OS X any more, so I can't effectively test them. I'm not sure if Tokio and Mark are in the same boat though. I can't build Python 2.3 either, but at least there, I don't have to (thanks Apple!). As for Mailman 2.2, there are lots and lots of features I want to use from Python 2.4. Built-in sets, generators, PEP 292 $-strings (pioneered in Mailman), decorators, and the subprocess module to name a few. Of the new-in-Python 2.5 features I'd use but can live without, probably conditional expressions absolute imports, and the with statement are the most interesting. Oh, and the built-in sqlite3 package <wink>. http://www.python.org/doc/2.3/whatsnew/whatsnew23.html http://www.python.org/doc/2.4/whatsnew/whatsnew24.html http://www.python.org/doc/2.5/whatsnew/whatsnew25.html - -Barry -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iQCVAwUBRRsx7nEjvBPtnXfVAQI3SgP/b3jeJti1AVveujcH1gwfwcwtG1LpU23X ECNQP2wybm6xwIhIl2Hjop58A6CjrauAZvWtF2YspMHeg6l/NnZ7DcCzc1VbKZQT cAhmsrHOh+MK5tIdLaOkQtl4T8D8i8tmtLrTDO+Wh6rhfG/oVhDa2IbNrdUZ59LQ yDvB1Nc+1m0= =yYt8 -----END PGP SIGNATURE----- _______________________________________________ Mailman-Developers mailing list Mailman-Developers@python.org http://mail.python.org/mailman/listinfo/mailman-developers Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-developers%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-developers/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq01.027.htp
