The 2024 version allows casting as an action or ritual, whereas 2014 is only action. It specifies "up to 10 minutes" duration, but duration remains functionally the same. The 2024 version grants immunity to thunder damage and the Deafened condition, whereas 2014 states immunity to thunder damage and deafening effect.
