I subscribe to the mailman support list and have been following a tthread on mailman 3. An excerpt here:

Mailman 2 is definitely end of life. I am the only one actively supporting it at this point and while I continue to offer help and fix bugs, it's not what I want to be doing.
Is there any planned date where security updates end?
Is there a plan, especially a migration plan for existing mailman 2 users in VM?
