* Add `PlayerView.isControllerVisible`
([#4385](https://github.com/google/ExoPlayer/issues/4385)).
* Improved performance when playing high frame-rate content, and when playing
at greater than 1x speed
([#2777](https://github.com/google/ExoPlayer/issues/2777)).
* Expose all internal ID3 data stored in MP4 udta boxes, and switch from using
CommentFrame to InternalFrame for frames with gapless metadata in MP4.
* Allow setting the `Looper`, which is used to access the player, in
