* DRM:
* Fix playback failure when switching from PlayReady protected content to
Widevine or Clearkey protected content in a playlist.
* Analytics:
* Pass a `DecoderReuseEvaluation` to `AnalyticsListener`'s
`onVideoInputFormatChanged` and `onAudioInputFormatChanged` methods. The
`DecoderReuseEvaluation` indicates whether it was possible to re-use an
existing decoder instance for the new format, and if not then the
reasons why.
* IMA extension:
* Upgrade IMA SDK dependency to 3.21.0, and release the `AdsLoader`
([#7344](https://github.com/google/ExoPlayer/issues/7344)).
