I am running mailman 3 in docker and trying to figure out -how to upgrade -can you back out.
For example I installed docker with a git pull • git clone https://github.com/maxking/docker-mailman
docker images shows
REPOSITORY TAG IMAGE ID CREATED SIZE
maxking/mailman-web 0.3 9ba9d3d7084d 4 months ago 487MB
maxking/mailman-core 0.3 26c920c0094b 4 months ago 178MB

I only installed it a few months ago, am I really on 0.3.0 , I assume I am on 3.0 from 2019 and that is what "git clone https://github.com/maxking/docker-mailman" gets????
looking at the release matrix "https://github.com/maxking/docker-mailman/releases?page=2" It looks like the latest releases are 0.4.1 for core & 0.4.2 for web,
How do I upgrade, is it a "git pull" or "docker update" command? If something does not work, is there a way to back out?
What version should I go to from 0.3? I am thinking it should be v0.3.12 cause that won't break anything? But how do I do that?
The documentation at https://asynchronous.in/docker-mailman/. says
