* Support encrypted initialization segments
([#5441](https://github.com/google/ExoPlayer/issues/5441)).
* Parse `EXT-X-MEDIA` `CHARACTERISTICS` attribute into `Format.roleFlags`.
* MPEG-TS: enable HDMV DTS stream detection only if a flag is set. By default
(if the flag is not set), the 0x82 elementary stream type is now treated as an
SCTE subtitle track
([#5330](https://github.com/google/ExoPlayer/issues/5330)).
* `ExtractorMediaSource` renamed to `ProgressiveMediaSource`.
* Support for playing spherical videos on Daydream.
* Improve decoder re-use between playbacks. TODO: Write and link a blog post
