[MM3-users] Solved issues not in Docker-mailman rolling releases

I am currently using Docker-mailman rolling releases and with great respect to the maintainer's time it was my impression from @maxking that rolling releases was likely to be one week behind the development.

In my report of https://gitlab.com/mailman/mailman/issues/444 @msapiro commented that #444 is a duplicate of #406 (closed) which was fixed by !322 (merged), but !322 was merged a month ago.

Thinking that I wasn't up to speed, I did a docker pull quay.io/maxking/mailman-core:rolling only got 'XXXXXXXXXXXX: Already exists'. Also docker images shows 'quay.io/maxking/mailman-core rolling 1654a3226db8 7 weeks ago 179.3 MB'.

Not to be umpolite, did I misunderstand the concept?
