Here is the release note:
Dashcam is now easier to setup or erase. After plugging in a USB drive, tap Controls > Safety & Security > FORMAT USB DEVICE to format and create the associated folders for Dashcam. Note: Formatting the USB drive will also delete any existing clips.
Playing Backgammon against your Tesla has now become more difficult. The most difficult level has now been trained with 20+ million games. Challenge your Tesla to a game by tapping the Application Launcher, then tap Entertainment > Arcade > Backgammon. Note: As usual, the Tesla Arcade is only available when your car is in PARK.
This release contains minor improvements and bug fixes.
It is less bug fixes and more an entirely new difficulty. Obviously not as important to many owners, but it is the first "Tesla trained AI" difficulty in any games.— Teslascope (@teslascope) May 6, 2020
That alone is pretty cool!
