I've just uploaded the Mailman 2.0 beta 2 tarball to the following locations:
http://www.list.org/mailman.tar.gz http://download.sourceforge.net/mailman/mailman-2.0beta2.tgz ftp://ftp.python.org/pub/mailman/mailman-2.0beta2.tgz
See the UPGRADING file for details on upgrading from 1.1 or 2.0beta1. See the NEWS file for a complete description of changes for every version; below is an excerpt for changes since 2.0beta1.
Barring any showstopping bugs, this will be the last release until I finish my taxes. :)
-------------------- snip snip --------------------
Rewritten gate_news cron script which should be more efficient and avoid race and locking problems. Each list now maintains its own watermark, and when you use the admin CGI script to turn on gating from Usenet->mail, an automatic mass catch up is done to avoid flooding the mailing list. cron/gate_news's command line interface has also changed. See its docstring for details.
A new cron script called qrunner has been added to retry message deliveries that fail because of temporary smtpd problems.
New command line script called bin/list_lists which does exactly that: lists all the mailing lists on the system (much like the listinfo CGI does).
bin/withlist is now directly executable, however if you want to use python -i, you must still explicitly invoke it. bin/withlist also now cleans up after itself by unlocking any locked lists. It does NOT save any dirty lists though - you must do this explicitly.
$prefix permissions (and all subdirs) must now be 02775. bin/check_perms has been updated to fix all the subdir permissions.
"make update" (a.k.a. bin/update) is run automatically when you do a "make install"
The CGI driver script now puts information about the Python environment into the logs/error file (but not the diagnostic web page).
Bug fixes and some performance improvements
