• Fixed an issue to work around a bug in the Google IMA SDK affecting Android Chrome 84 only where unplayable linear ad MIME types were being erroneously selected.

• Fixed an issue where calling stop() disables sound completely when resuming playback on HLS streams.
• Fixed a bug where some data was not being exposed in the on('meta') and on('metadataCueParsed') events.
• Fixed a bug where the mute/unmute button was not properly read by a screen reader.
• Fixed an issue causing some streams to show an erroneously long duration.

Service release, no new features.

Updates

• Added a method, setFloating(), which starts and stops the player from floating, and getFloating(), which returns the current floating status.
• Added a new configuration option in the floating object, mode, which defaults to notVisible, which is current behavior for floating when the original container would be out of view. always can be used to start floating and never stop unless updated with the API, and never can be used to not float, unless updated by API.
• Made some big improvements to the way we do scheduling in the Google IMA client:
  • We now make ad request for each ad break, rather than creating a VMAP for the entire schedule for each playlist item.   
  • The adRequest event has been changed to fire each time we make ad request to IMA SDK.   
  • Added a new adLoaded event, which fires when IMA's LOADED event fires.
• Deprecated the ability to use the playlistItem event to update an ad schedule. By the time that event fires, the schedule for the playlist item has already been created, so the change does not have an effect. Please use setPlaylistItemCallback to properly update the ad schedule.

Fixes

• Fixed a bug preventing preloading on Safari desktop and iOS browsers.
• Fixed a bug causing the wrong audio track to appear selected after the setCurrentAudioTrack is called.

• Fixed an issue causing some mid-roll emsg cues to be missed.

• Fixed overlapping right-to-left text displayed over ads in the Google IMA client.
• Fixed a bug causing captions to not be cleared when going to an ad break on iOS Safari.
• Fixed a bug on IE11 where the volume slider could not be used.
• Fixed an issue where the player errors or gets stuck in an idle state when loading the last playlist item if it is rejected by the async playlist API callback.

Updates

Updates

• Improved compatibility with the AMP framework and quality assurance capabilities of our amp-jwplayer component.
• To supplement documentation we maintain on amp.dev, we created JWP developer documentation on embedding an AMP player and working with AMP analytics.
• Added a configuration option, playlistIndex, which enables a playlist to be loaded and start playback from any item within it, not just the first. The default of this option is a 0 index.

Fixes

• Fixed a bug preventing captions from working on some live streams.
• Fixed a problem with Chromecast where captions were not casting.
• Fixed an issue where the wrong captions track appeared to be selected if both in-manifest and side-loaded captions tracks are present.

Known Issue

• The video-seconds-played trigger listed for configuration in amp-video-analytics does not work properly in this release. This will be fixed in a future release. All other triggers listed should operate as expected.

Updates 

Core Player

• Added a new property, cueType, to the addCues event, which adds a custom CSS class that can be used for additional cue styling in the format of .jw-cue-type-{cueType}.
• Added a new CSS class .jw-cue-type-ads to ad cues so they can be styled separately from other cues, such as chapter markers.
• Added support for 608 caption track names defined in the parent manifest via #EXT-X-MEDIA:TYPE=CLOSED-CAPTIONS tags.

Advertising

• To the VAST client, added support for the VAST 4.1 viewableImpression node, which adds a tracking pixel to the page when the adImpression event fires based on whether the ad is viewable at that time.
