It appears nothing major has changed in the latest Tesla update. Version 2020.48.30 starting rolling out a few days ago and today it hit my Tesla Model 3 SR+ model. The official Release Notes show the same information as the previous update (2020.48.25), which did contain many updates. So it appears that version 2020.48.30 just contains some bug fixes, which is always welcome.
