Mailman 2.1.36 had a serious bug. Thanks to Joel Lord for finding and reporting it.
I have just released Mailman 2.1.37 to fix that issue. It is reported at https://bugs.launchpad.net/mailman/+bug/1950833 and is fixed at https://bazaar.launchpad.net/~mailman-coders/mailman/2.1/revision/1878
Mailman 2.1.36 should not be installed - upgrade from Mailman <= 2.1.35 directly to 2.1.37.
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 2.1.37 is the seventh such patch release.
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.
