* Add `Player.onPlaybackSuppressionReasonChanged` to allow listeners to
detect playbacks suppressions (e.g. audio focus loss) directly
([#6203](https://github.com/google/ExoPlayer/issues/6203)).
* Expose the raw ICY metadata through `IcyInfo`
([#6476](https://github.com/google/ExoPlayer/issues/6476)).
