   show how to render video to a `GLSurfaceView` while applying a GL shader.
   ([#6920](https://github.com/google/ExoPlayer/issues/6920)).
   ([#6920](https://github.com/google/ExoPlayer/issues/6920)).
-*   Core library:
-    *   Add API in `AnalyticsListener` to report video frame processing offset.
-        `MediaCodecVideoRenderer` reports the event.
-    *   Add fields `videoFrameProcessingOffsetUsSum` and
-        `videoFrameProcessingOffsetUsCount` in `DecoderCounters` to compute the
-        average video frame processing offset.
-    *   Add playlist API
-        ([#6161](https://github.com/google/ExoPlayer/issues/6161)).
-    *   Add `play` and `pause` methods to `Player`.
-    *   Add `Player.getCurrentLiveOffset` to conveniently return the live
-        offset.
-    *   Add `Player.onPlayWhenReadyChanged` with reasons.
-    *   Add `Player.onPlaybackStateChanged` and deprecate
-        `Player.onPlayerStateChanged`.
-    *   Deprecate and rename `getPlaybackError` to `getPlayerError` for
-        consistency.
-    *   Deprecate and rename `onLoadingChanged` to `onIsLoadingChanged` for
-        consistency.
-    *   Make `MediaSourceEventListener.LoadEventInfo` and
-        `MediaSourceEventListener.MediaLoadData` top-level classes.
-    *   Rename `MediaCodecRenderer.onOutputFormatChanged` to
-        `MediaCodecRenderer.onOutputMediaFormatChanged`, further clarifying the
-        distinction between `Format` and `MediaFormat`.
-    *   Move player message-related constants from `C` to `Renderer`, to avoid
-        having the constants class depend on player/renderer classes.
-    *   Split out `common` and `extractor` submodules.
-    *   Allow to explicitly send `PlayerMessage`s at the end of a stream.
-    *   Add `DataSpec.Builder` and deprecate most `DataSpec` constructors.
-    *   Add `DataSpec.customData` to allow applications to pass custom data
-        through `DataSource` chains.
-    *   Add a sample count parameter to `MediaCodecRenderer.processOutputBuffer`
-        and `AudioSink.handleBuffer` to allow batching multiple encoded frames
-        in one buffer.
-    *   Add a `Format.Builder` and deprecate all `Format.create*` methods and
-        most `Format.copyWith*` methods.
-    *   Split `Format.bitrate` into `Format.averageBitrate` and
-        `Format.peakBitrate`
-        ([#2863](https://github.com/google/ExoPlayer/issues/2863)).
-*   Text:
-    *   Parse `<ruby>` and `<rt>` tags in WebVTT subtitles (rendering is coming
-        later).
-    *   Parse `text-combine-upright` CSS property (i.e. tate-chu-yoko) in WebVTT
-        subtitles (rendering is coming later).
-    *   Parse `tts:combineText` property (i.e. tate-chu-yoko) in TTML subtitles
-        (rendering is coming later).
-    *   Fix `SubtitlePainter` to render `EDGE_TYPE_OUTLINE` using the correct
-        color ([#6724](https://github.com/google/ExoPlayer/pull/6724)).
-    *   Add support for WebVTT default
-        [text](https://www.w3.org/TR/webvtt1/#default-text-color) and
-        [background](https://www.w3.org/TR/webvtt1/#default-text-background)
-        colors ([PR #4178](https://github.com/google/ExoPlayer/pull/4178),
-        [issue #6581](https://github.com/google/ExoPlayer/issues/6581)).
-    *   Catch-and-log all fatal exceptions in `TextRenderer` instead of
-        re-throwing, allowing playback to continue even if subtitles fail
-        ([#6885](https://github.com/google/ExoPlayer/issues/6885)).
-    *   Parse `tts:ruby` and `tts:rubyPosition` properties in TTML subtitles
-        (rendering is coming later).
-*   DRM:
-    *   Add support for attaching DRM sessions to clear content in the demo app.
-    *   Remove `DrmSessionManager` references from all renderers.
-        `DrmSessionManager` must be injected into the MediaSources using the
-        MediaSources factories.
-*   Downloads: Merge downloads in `SegmentDownloader` to improve overall
-    download speed ([#5978](https://github.com/google/ExoPlayer/issues/5978)).
-*   MP3: Add `IndexSeeker` for accurate seeks in VBR streams
-    ([#6787](https://github.com/google/ExoPlayer/issues/6787)). This seeker is
-    enabled by passing `FLAG_ENABLE_INDEX_SEEKING` to the `Mp3Extractor`. It may
-    require to scan a significant portion of the file for seeking, which may be
-    costly on large files.
-*   MP4: Store the Android capture frame rate only in `Format.metadata`.
-    `Format.frameRate` now stores the calculated frame rate.
-*   Testing
-    *   Upgrade Truth dependency from 0.44 to 1.0.
-    *   Upgrade to JUnit 4.13-rc-2.
-*   UI
-    *   Move logic of prev, next, fast forward and rewind to ControlDispatcher
-        ([#6926](https://github.com/google/ExoPlayer/issues/6926)).
-*   Demo apps: Add
-    [GL demo app](https://github.com/google/ExoPlayer/tree/dev-v2/demos/gl) to
-    show how to render video to a `GLSurfaceView` while applying a GL shader.
-    ([#6920](https://github.com/google/ExoPlayer/issues/6920)).
-*   Metadata: Add minimal DVB Application Information Table (AIT) support
