Quick question: is a saved configuration in v12 beta (Backup and Restore) backward compatible with v11.xx?
Opus 12 can load configurations from Opus 11 and earlier versions.
Going the other way may work but isn't guaranteed, since there will be things in a newer config which older versions did not know how to handle. Instead, you should make a backup of your Opus 11 config (Settings > Backup & Restore) before installing Opus 12, in case you wish to go back to it.
Makes sense. Thanks.
