-* SimpleExoPlayerView: Automatically apply video rotation if
-  `SimpleExoPlayerView` is configured to use `TextureView`
-  ([#91](https://github.com/google/ExoPlayer/issues/91)).
+* Downloading: Add `DownloadService`, `DownloadManager` and

 * Player interface:
-  * Add `Player.VideoComponent`, `Player.TextComponent` and
-    `Player.MetadataComponent` interfaces that define optional video, text and
-    metadata output functionality. New `getVideoComponent`, `getTextComponent`
-    and `getMetadataComponent` methods provide access to this functionality.
   * Add optional parameter to `stop` to reset the player when stopping.
   * Add a reason to `EventListener.onTimelineChanged` to distinguish between
     initial preparation, reset and dynamic updates.

     more customization of the message. Now supports setting a message delivery
     playback position and/or a delivery handler

-* UI components:
-  * Generalized player and control views to allow them to bind with any
-    `Player`, and renamed them to `PlayerView` and `PlayerControlView`
-    respectively.
-  * Made `PlayerView`'s play button behave correctly when the player is ended

+* Add `ExoPlayer.setSeekParameters` for controlling how seek operations are
+  performed. The `SeekParameters` class contains defaults for exact seeking and
+  seeking to the closest sync points before, either side or after specified seek
+  positions. `SeekParameters` are not currently supported when playing HLS 
+  streams.
+* DefaultTrackSelector:
+  * Replace `DefaultTrackSelector.Parameters` copy methods with a builder.
+  * Support disabling of individual text track selection flags.
 * Buffering:
   * Allow a back-buffer of media to be retained behind the current playback
     position, for fast backward seeking. The back-buffer can be configured by
     custom `LoadControl` implementations.
-  * Add ability for `SequenceableLoader` to reevaluate its buffer and discard
+  * Add ability for `SequenceableLoader` to re-evaluate its buffer and discard
     buffered media so that it can be re-buffered in a different quality.
   * Allow more flexible loading strategy when playing media containing multiple
     sub-streams, by allowing injection of custom `CompositeSequenceableLoader`
     factories through `DashMediaSource.Factory`, `HlsMediaSource.Factory`,
     `SsMediaSource.Factory`, and `MergingMediaSource`.
   * Play out existing buffer before retrying for progressive live streams

 * DRM: Optimistically attempt playback of DRM protected content that does not
   declare scheme specific init data in the manifest. If playback of clear
   samples without keys is allowed, delay DRM session error propagation until
   keys are actually needed
   ([#3630](https://github.com/google/ExoPlayer/issues/3630)).
 * DASH:
-  * Support in-band Emsg events targeting player with scheme id
-    "urn:mpeg:dash:event:2012" and scheme value of either "1", "2" or "3".
-  * Support DASH manifest EventStream elements.
-* DefaultTrackSelector:

+  * Support EventStream elements in DASH manifests.
 * HLS:
     * Add opt-in support for chunkless preparation in HLS. This allows an
       HLS source to finish preparation without downloading any chunks, which can
       significantly reduce initial buffering time
-      ([#3149](https://github.com/google/ExoPlayer/issues/3149)).

     * Fix ID3 context reuse across segment format changes
       ([#3622](https://github.com/google/ExoPlayer/issues/3622)).
     * Use long for media sequence numbers
       ([#3747](https://github.com/google/ExoPlayer/issues/3747))
     * Add initial support for the EXT-X-GAP tag.
-* New Cast extension: Simplifies toggling between local and Cast playbacks.
 * Audio:
   * Support TrueHD passthrough for rechunked samples in Matroska files
     ([#2147](https://github.com/google/ExoPlayer/issues/2147)).
   * Support resampling 24-bit and 32-bit integer to 32-bit float for high
     resolution output in `DefaultAudioSink`
