I am pleased to announce the release of Mailman 2.1.28.
Python 2.6 is the minimum supported, but Python 2.7 is strongly recommended.
This is a minor security fix release. It also has some i18n updates and a couple of bug fixes and adds the ability to edit list specific templates through the web admin UI in a supported language other than the list's default. See the attached README.txt for details.
For details of the security issue, see the report at https://bugs.launchpad.net/mailman/+bug/1780874 which also includes a patch for those who want to fix this issue without upgrading.
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.
