Hello I've been using Unraid for about a month now. So far, I'm very happy with it and it's running perfectly. Now for my question: I get a notification about once a week that a new version is available. How do you handle this? Do you install the update immediately, or do you only do it quarterly since the server needs to be restarted after an update?

It is really up to you.

Updates are not normally as frequent, but there have been some important recent security fixes to the Unraid 7,2.x series which have resulted in rapid updates, and also 7.3.0 has just reached stable status

Okay, thank you very much. I thought the updates were always this frequent.
