I am pleased to announce the release Mailman 2.1.20.
Python 2.4 is the minimum supported, but Python 2.7 is recommended.
This release has one new feature, a few bug fixes, an update to the Polish message catalog and a fix for a recently discovered security vulnerability.
See the attached README for more details.
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.
