 # Release notes
 
-### dev-v2 (not yet released)
+### 2.16.0 (2021-11-04)
 
 *   Core Library:
+    *   Deprecate `SimpleExoPlayer`. All functionality has been moved to
+        `ExoPlayer` instead. `ExoPlayer.Builder` can be used instead of
+        `SimpleExoPlayer.Builder`.
+    *   Add track selection methods to the `Player` interface, for example,
+        `Player.getCurrentTracksInfo` and `Player.setTrackSelectionParameters`.
+        These methods can be used instead of directly accessing the track
+        selector.
     *   Enable MediaCodec asynchronous queueing by default on devices with API
         level >= 31. Add methods in `DefaultMediaCodecRendererFactory` and
         `DefaultRenderersFactory` to force enable or force disable asynchronous
         queueing ([6348](https://github.com/google/ExoPlayer/issues/6348)).
-    *   Add 12 public method headers to `ExoPlayer` that exist in
-        `SimpleExoPlayer`, such that all public methods in `SimpleExoPlayer` are
-        overrides.
+    *   Remove final dependency on `jcenter()`.
+    *   Fix `mediaMetadata` being reset when media is repeated
+        ([#9458](https://github.com/google/ExoPlayer/issues/9458)).
+    *   Adjust `ExoPlayer` `MediaMetadata` update priority, such that values
+        input through the `MediaItem.MediaMetadata` are used above media derived
+        values.
     *   Move `com.google.android.exoplayer2.device.DeviceInfo` to
         `com.google.android.exoplayer2.DeviceInfo`.
     *   Move `com.google.android.exoplayer2.drm.DecryptionException` to
         `com.google.android.exoplayer2.decoder.CryptoException`.
     *   Move `com.google.android.exoplayer2.upstream.cache.CachedRegionTracker`
         to `com.google.android.exoplayer2.upstream.CachedRegionTracker`.
-    *   Remove `ExoPlayerLibraryInfo.GL_ASSERTIONS_ENABLED`. Use
-        `GlUtil.glAssertionsEnabled` instead.
     *   Move `Player.addListener(EventListener)` and
         `Player.removeListener(EventListener)` out of `Player` into subclasses.
-    *   Fix `mediaMetadata` being reset when media is repeated
-        ([#9458](https://github.com/google/ExoPlayer/issues/9458)).
-    *   Remove final dependency on `jcenter()`.
-    *   Adjust `ExoPlayer` `MediaMetadata` update priority, such that values
-        input through the `MediaItem.MediaMetadata` are used above media derived
-        values.
-*   Video:
-    *   Fix bug in `MediaCodecVideoRenderer` that resulted in re-using a
-        released `Surface` when playing without an app-provided `Surface`
-        ([#9476](https://github.com/google/ExoPlayer/issues/9476)).
-*   DRM:
-    *   Log an error (instead of throwing `IllegalStateException`) when calling
-        `DefaultDrmSession#release()` on a fully released session
-        ([#9392](https://github.com/google/ExoPlayer/issues/9392)).
 *   Android 12 compatibility:
     *   Keep `DownloadService` started and in the foreground whilst waiting for
         requirements to be met on Android 12. This is necessary due to new
