 __NOTE:__ A settings reset will be performed on an update for versions earlier than 20211122. Backup and restore of settings is recommended.  
 __IMPORTANT!__  A new setting has been introduced for ganged axes motors in version 20211121.  
 I have only bench tested this for a couple of drivers, correct function should be verified after updating by those who have more than three motors configured.
