Just curious if anyone else had any success in finding a way to prevent the update to the latest Steam version since I am in a similar boat. The server I set up allows friends to join who are playing on Xbox and PC Gamepass who get the latest patches after Steam does (over a week for the most recent patch). As someone else mentioned, this makes the server unusable to those players until the Xbox/Windows Store catches up. I tried to use the line ich777 mentioned to pull older branches as a test, but like the above post mentioned it seems like all branches besides the current public branch are locked.
Thanks everyone for all you do btw, newer to Unraid here but first time poster, and reading posts on this forum has been super helpful in learning things. Also thanks to ich777 for your server containers.
