You can opt-in automatic updates. If you install the non-container package, you can set it to auto upgrade.

With containers it's a questionable/clunky implementation but possible. It only works in one flavor of their official image. On startup it will check if there is an update and download it and replace the application in the container. It breaks the point of containers obviously. It also only runs on startup, so you need to restart the container to get it to run.

Nope, at least not on the platform I'm on. Just get the popup when accessing media when there is an update and can automate it or schedule for evening, but no way to automatically update it.

I don't think they force upgrade but it looks like the fix was part of 1.43.3 and my app is on 1.43.4
