I am pleased to announce the third release candidate for Mailman 2.1.16.
Python 2.4 is the minimum supported, but Python 2.7 is recommended.
This release has a few new features and several bug fixed as detailed in the attached README.
Differences from the second candidate are the renaming of the author_is_list feature to from_is_list to more accurately describe what it does. This feature has also been extended to provide the option of leaving the original message intact and wrapping it in an outer part with Content-Type: message/rfc822.
The from_is_list feature is considered experimental and subject to change in future releases. It is being released now as a "candidate" to allow some exposure before the final 2.1.16 release which should occur in October.
Mailman is free software for managing email mailing lists and e-newsletters. Mailman is used for all the python.org and SourceForge.net mailing lists, as well as at hundreds of other sites.

I anticipate that the 2.1.16 final release will be in Mid October. Bugs found between now and then will be fixed if possible, but I hope that most if not all changes between now and then will be i18n updates. Please send any updates to the templates and/or message catalogs in the 2.1.16rc3 release directly to me no later than 15 Oct 2013.
