Note those are the versions of the containers, not the versions of the software they contain. See the core/requirements.txt and web/requirements.txt files for the actual Mailman component versions that go into them.
If you build your own images (I plan to do so), you can also change the pip calls to build from any git repository.
Are these images still maintained and suitable for a new deployment, or is another container image or installation method now recommended?
They're still maintained (most recent commit in June 2026). I think they're just stable enough that Abhilash isn't playing with the containers much at this point. They're not a polished product, but both docker and Mailman are strong enough for a straightforward implementation to be production-ready for "small vanilla" instances. I suspect that most enterprise installs will want to tweak them, but it's as good a place to start as any I know of.
