The release notes in Beats’ own words for iOS:
“You asked for it, and we listened! In this latest release we’ve added:
● Tune Your Taste — Want to switch up your Just For You recommendations? Change your favorite genres and artists with the Tune Your Taste feature in Settings
● Sentence History — View your most recently played songs from The Sentence
● Verified Badges — That red check mark means the profile is certified as legit by Beats
● Player Improvements — We fixed a ton of bugs to make playback more smooth and reliable
…and much, much more!”
