  • The WindowClient.navigate() method has been implemented. This method lets you open a specified URL into a client window which is being controlled by the service worker (error 1218148).

Audio/Video

  • The AlignSetting enum (representing possible values for VTTCue.align) incorrectly previously included the value "middle" instead of "center". This has been corrected (error 1276130).
  • The non-standard and experimental method HTMLMediaElement.seekToNextFrame() now seeks to the next frame in the media asynchronously, rather than synchronously, and returns a Promise which resolves once the seek is complete.
  • The implementation of HTMLTrackElement has been corrected to allow <track> elements to load resources even if not in a document (error 871747).
