-### dev-v2 (not yet released)
-*   Core Library:
-    *   Move `com.google.android.exoplayer2.device.DeviceInfo` to
-        `com.google.android.exoplayer2.DeviceInfo`.
-*   Android 12 compatibility:
-    *   Disable platform transcoding when playing content URIs on Android 12.
-    *   Add `ExoPlayer.setVideoChangeFrameRateStrategy` to allow disabling of
-        calls from the player to `Surface.setFrameRate`. This is useful for
-        applications wanting to call `Surface.setFrameRate` directly from
-        application code with Android 12's `Surface.CHANGE_FRAME_RATE_ALWAYS`.
-*   GVR extension:
-    *   Remove `GvrAudioProcessor`, which has been deprecated since 2.11.0.
-*   Remove deprecated symbols:
-    *   Remove `Renderer.VIDEO_SCALING_MODE_*` constants. Use identically named
-        constants in `C` instead.
-    *   Remove `C.MSG_*` constants. Use identically named constants in
-        `Renderer` instead, except for `C.MSG_SET_SURFACE`, which is replaced
-        with `Renderer.MSG_SET_VIDEO_OUTPUT`.
-    *   Remove `DeviceListener`. Use `Player.Listener` instead.
