### r2.1.1 ###
### r2.2.0 ###
Bugfix release only. Users of r2.1.0 and r2.0.x should proactively update to
this version.
* Demo app: Automatic recovery from BehindLiveWindowException, plus improved
handling of pausing and resuming live streams
([#2344](https://github.com/google/ExoPlayer/issues/2344)).
* AndroidTV: Added Support for tunneled video playback
([#1688](https://github.com/google/ExoPlayer/issues/1688)).
* DRM: Renamed StreamingDrmSessionManager to DefaultDrmSessionManager and
added support for using offline licenses
([#876](https://github.com/google/ExoPlayer/issues/876)).
* DRM: Introduce OfflineLicenseHelper to help with offline license acquisition,
renewal and release.
* UI: Updated player control assets. Added vector drawables for use on API level
21 and above.
* UI: Made player control seek bar work correctly with key events if focusable
([#2278](https://github.com/google/ExoPlayer/issues/2278)).
* HLS: Improved support for streams that use EXT-X-DISCONTINUITY without
EXT-X-DISCONTINUITY-SEQUENCE
([#1789](https://github.com/google/ExoPlayer/issues/1789)).
* HLS: Support for EXT-X-START tag
([#1544](https://github.com/google/ExoPlayer/issues/1544)).
* HLS: Check #EXTM3U header is present when parsing the playlist. Fail
gracefully if not ([#2301](https://github.com/google/ExoPlayer/issues/2301)).
* HLS: Fix memory leak
([#2319](https://github.com/google/ExoPlayer/issues/2319)).
* HLS: Fix non-seamless first adaptation where master playlist omits resolution
tags ([#2096](https://github.com/google/ExoPlayer/issues/2096)).
* HLS: Fix handling of WebVTT subtitle renditions with non-standard segment file
extensions ([#2025](https://github.com/google/ExoPlayer/issues/2025) and
[#2355](https://github.com/google/ExoPlayer/issues/2355)).
* HLS: Better handle inconsistent HLS playlist update
([#2249](https://github.com/google/ExoPlayer/issues/2249)).
* DASH: Don't overflow when dealing with large segment numbers
([#2311](https://github.com/google/ExoPlayer/issues/2311)).
* DASH: Fix propagation of language from the manifest
([#2335](https://github.com/google/ExoPlayer/issues/2335)).
* SmoothStreaming: Work around "Offset to sample data was negative" failures
([#2292](https://github.com/google/ExoPlayer/issues/2292),
[#2101](https://github.com/google/ExoPlayer/issues/2101) and
[#1152](https://github.com/google/ExoPlayer/issues/1152)).
* MP3/ID3: Added support for parsing Chapter and URL link frames
([#2316](https://github.com/google/ExoPlayer/issues/2316)).
* MP3/ID3: Handle ID3 frames that end with empty text field
([#2309](https://github.com/google/ExoPlayer/issues/2309)).
* Added ClippingMediaSource for playing clipped portions of media
([#1988](https://github.com/google/ExoPlayer/issues/1988)).
* Added convenience methods to query whether the current window is dynamic and
seekable ([#2320](https://github.com/google/ExoPlayer/issues/2320)).
* Support setting of default headers on HttpDataSource.Factory implementations
([#2166](https://github.com/google/ExoPlayer/issues/2166)).
* Fixed cache failures when using an encrypted cache content index.
* Fix visual artifacts when switching output surface
([#2093](https://github.com/google/ExoPlayer/issues/2093)).
* Fix gradle + proguard configurations.
* Fix player position when replacing the MediaSource
([#2369](https://github.com/google/ExoPlayer/issues/2369)).
* Misc bug fixes, including
[#2330](https://github.com/google/ExoPlayer/issues/2330),
[#2269](https://github.com/google/ExoPlayer/issues/2269),
[#2252](https://github.com/google/ExoPlayer/issues/2252),
