More than a decade after its last major rewrite, the GNU Mailman mailing list manager project aims to release its 3.0 suite in April, during the sprints following PyCon North America. Mailman 3 is a major rewrite that includes a new user membership system, a REST API, an archiver replacement for Pipermail, and a better web interface for subscriptions and settings — but it carries with it a few new dependencies as well.
