If you don't want to play American Truck Simulator on the latest public version and would rather play a different beta branch to play older versions, here's how to change the version of your American Truck Simulator server.

When changing server versions, you must also change your ATS game version to match the version of your server. The process for downgrading your game version can be found here.
