### 2.8.2 ###
* IMA: Don't advertise support for video/mpeg ad media, as we don't have an
extractor for this ([#4297](https://github.com/google/ExoPlayer/issues/4297)).
* DASH: Fix playback getting stuck when playing representations that have both
sidx atoms and non-zero presentationTimeOffset values.
* HLS:
* Allow injection of custom playlist trackers.
* Fix adaptation in live playlists with EXT-X-PROGRAM-DATE-TIME tags.
* Mitigate memory leaks when `MediaSource` loads are slow to cancel
([#4249](https://github.com/google/ExoPlayer/issues/4249)).
* Fix inconsistent `Player.EventListener` invocations for recursive player state
changes ([#4276](https://github.com/google/ExoPlayer/issues/4276)).
* Fix `MediaCodec.native_setSurface` crash on Moto C
([#4315](https://github.com/google/ExoPlayer/issues/4315)).
* Fix missing whitespace in CEA-608
([#3906](https://github.com/google/ExoPlayer/issues/3906)).
* Fix crash downloading HLS media playlists
([#4396](https://github.com/google/ExoPlayer/issues/4396)).
* Fix a bug where download cancellation was ignored
([#4403](https://github.com/google/ExoPlayer/issues/4403)).
* Set `METADATA_KEY_TITLE` on media descriptions
([#4292](https://github.com/google/ExoPlayer/issues/4292)).
* Allow apps to register custom MIME types
([#4264](https://github.com/google/ExoPlayer/issues/4264)).
