On behalf of the rest of the Mailman Cabal, I'm very happy (and somewhat relieved) to announce the release of Mailman 1.0. I've just uploaded the tarball to www.list.org so follow the links there to download it.
Mailman -- the GNU Mailing List Manager -- is software to help manage email discussion lists, much like Majordomo and Smartmail. Unlike most similar products, Mailman gives each mailing list a web page, and allows users to subscribe, unsubscribe, etc. over the web. Even the list manager can administer his or her list entirely from the web. Mailman also integrates most things people want to do with mailing lists, including archiving, mail-to-news gateways, and so on.
Mailman is written almost completely in Python (there's a little bit of C for security purposes). Mailman is distributed under the terms of the GPL.
From the NEWS file, here are the list of changes since 1.0rc3:
Configure script now allows $PREFIX (by default /home/mailman) to be permissions 02755. Also, configure now tests for vsnprintf()
Workaround, taken from GNU screen, for systems missing vsnprintf()
Return-Receipt-To: and Disposition-Notification-To: headers are always removed from posted messages (they can be used to troll for list membership).
Workaround for MSIE4.01 (and possibly other versions) bug in the handling of cookies.
A small collection of other bug fixes.
