Hey Everyone,

I am pleased to announce that Mailman Core 3.3.4 is now out.

Because of incompatibility with the new version of a downstream library (SQLAlchemy), this release add is setting 1.3.x as the max supported version of SQLAlchemy.

Even though it comes soon after 3.3.3, it has a lot of bug fixes and new features. Some notable ones are: * Email -join command now supports subscribing as digests with digest=<no|mime|plain> options being honored. * For anonymous lists, Mailman will filter all the headers except a few that can be configured using a new config option. * Mailman can do max_size checks on filtered message rather than original message (which might be larger before being filtered) * Previously deprecated --add, --del and --sync options from `mailman members` command are now removed. Their alternatives are `addmembers`, `delmembers` and `syncmembers` subcommands. * If configured, Mailman will add a report about content filtering.

A complete change log is available here:
