For the third time in as many days I have released a new Mailman 2.1 version. This one is 2.1.33 and fixes another content injection vulnerability. See the attached README.txt and the bug report at https://bugs.launchpad.net/mailman/+bug/1877379 for details.
Again, for those who don't want to install the full update, the above bug report contains a simple patch to fix the security issue.
As noted Mailman 2.1.30 was the last feature release of the Mailman 2.1 branch from the GNU Mailman project. There has been some discussion as to what this means. It means there will be no more releases from the GNU Mailman project containing any new features. There may be future patch releases to address the following:
i18n updates. security issues. bugs affecting operation for which no satisfactory workaround exists.
Mailman 2.1.31 is the first such patch release, Mailman 2.1.32 is the second and Mailman 2.1.33 is the third.
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.
