     *   Rename `DecoderCounters#inputBufferCount` to `queuedInputBufferCount`.
     *   Make `SimpleExoPlayer.renderers` private. Renderers can be accessed via
         `ExoPlayer.getRenderer`.
+    *   Enable support for Android platform diagnostics via
+        `MediaMetricsManager`. ExoPlayer will forward playback events and
+        performance data to the platform, which helps to provide system
+        performance and debugging information on the device. This data may also
+        be collected by Google
+        [if sharing usage and diagnostics data is enabled](https://support.google.com/accounts/answer/6078260)
+        by the user of the device. Apps can opt-out of contributing to platform
+        diagnostics for ExoPlayer with
+        `ExoPlayer.Builder.setUsePlatformDiagnostics(false)`.
 *   Android 12 compatibility:
     *   Upgrade the Cast extension to depend on
         `com.google.android.gms:play-services-cast-framework:20.1.0`. Earlier
