I am pleased to announce the release of Mailman 2.1.26.
Python 2.4 is the minimum supported, but Python 2.7 is strongly recommended.
This is a security and bug fix release with a couple of new features. See the attached README.txt for details.
For those who are concerned about the security vulnerability and can't upgrade immediately, there is a patch at https://bugs.launchpad.net/mailman/+bug/1747209/+attachment/5048344/+files/options.patch to fix the security issue. More information on the issue itself is in the bug report at https://bugs.launchpad.net/mailman/+bug/1747209.
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.
