Yup. I'm still maintaining the current status. A few minor things are broken like the app install scripts, but so long as the container can run steam games, I'm happy. Users can follow instructions online to install lutris if they want it...
Just to reiterate, I don't provide support in this forum any longer, all support and discussion happens on the discord server and is agnostic if unraid. If anyone wants to talk to me directly, you can come join us at https://unmanic.app/discord
The container has a pipeline to automatically fetch the latest updates once a week. That's why you are seeing docker image updates weekly without commits.
Since I manage a bunch of open source projects, my time gets split across them, this one has not received any love for a few months as I moved and never setup my server at the new place until last week. I've been busy writing new applications and updating other projects. Eventually steam headless will get more dev time from me for new features.
