I am not so pleased to announce the release of Mailman 2.1.29.
It turned out there was a bug in the security fix in 2.1.28 that broke the web admin and listinfo overview pages. This is fixed in Mailman 2.1.29. The patch referred to below has been corrected to fix this bug. There is also a patch attached to https://bugs.launchpad.net/mailman/+bug/1783417 which applies to 2.1.28 to fix this issue.
Python 2.6 is the minimum supported, but Python 2.7 is strongly recommended.
Mailman 2.1.28 was 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.
