Here’s the apple change-log, to save you a click:

Stolen Device Protection

Stolen Device Protection increases security of iPhone and Apple ID by requiring Face ID or Touch ID with no passcode fallback to perform certain actions.

Security Delay requires Face ID or Touch ID, an hour wait, and then an additional successful biometric authentication before sensitive operations like changing device passcode or Apple ID password can be performed.

Lock Screen

New Unity wallpaper honors Black history and culture in celebration of Black History Month.

Music

Collaborate on playlists allows you to invite friends to join your playlist and everyone can add, reorder, and remove songs.
