    - https://github.com/google/shaka-player/issues/13

Features:
  - The isTypeSupported polyfill has been removed and all EME APIs have been
    updated to the [Feb 9 2015 EME spec].
    - https://github.com/google/shaka-player/issues/2
  - Gaps and overlaps in SegmentTimeline are no longer treated as an error.
    Large gaps/overlaps will still generate a warning.
    - https://github.com/google/shaka-player/issues/24
  - HDCP-related failures are now translated into error events in Chrome 42+.
    - https://github.com/google/shaka-player/issues/14
  - The MPD Role tag is now supported as a way of indicating the main
    AdaptationSet for the purposes of language matching.
    - https://github.com/google/shaka-player/issues/20
  - More detail added to AJAX error events.
    - https://github.com/google/shaka-player/issues/18
  - The Player now dispatches buffering events.

  - Parser support for the new v1 PSSH layout, including parsing of key IDs.
    - https://github.com/google/shaka-player/issues/19
  - The fullscreen polyfill has been updated and expanded.
  - DashVideoSource refactored to split DASH-independent functionality into the
    generic StreamVideoSource.  This should simplify the implementation of new
    video sources for non-DASH manifest formats.  (Contributions welcome.)
  - Automatic build numbering has been added, with version numbers appearing in
    the test app UI.
  - The library has been published on [npm] and [cdnjs].
  - Release version numbering follows the [semantic versioning spec].
