I am pleased to announce the first release candidate for Mailman 2.1.21.
Python 2.4 is the minimum supported, but Python 2.7 is strongly recommended.
This release includes a few new features and several bug fixes. See the attached README for details.
Associated with these changes are six new and two modified strings in the i18n message catalogs. I strongly encourage anyone with an interest in translations of Mailman to get this release and help with updating the translations for the final 2.1.21 release which is planned for the end of February.
This candidate is expected to be quite stable. All the changes since 2.1.20 have been installed in the python.org Mailman as they were developed and are running without known issues. The only reason why this is a candidate and not a final release is to allow time for i18n updates to be in the final.
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.
