The JS SDK Method getCaptionLanguages() has been removed. Use getCaptions() from now on.
The JS SDK Method getAudioLanguages() has been replaced by getAudioTracks(). It will return an Array of Objects with language and isAudioDescription Attributes from now on.
The JS SDK now exposes the getCurrentMediaParent() Method, which can be called, if a Container (Playlist, AudioAlbum etc) is currently played. The Method will return the basic Metadata for the current parent Media.
The Configuration Option "sharingData" has been removed. If needed, the Configuration Option webURLRepresentation can be used. Although designed primarily for VAST Purposes, it is used too in creating the Sharing Dialogue, if present. Furthermore, it can be updated during Playback with updateConfiguration (on all Platforms).
the getMediaData() Method of the JS SDK for querying about the "current Media" has been deprecated, as its response was too big and confusing. It mixed various States of the currently playing Media and the current State of Playback.
Therefore, it was replaced by the new Methods getCurrentMedia() AND getCurrentPlaybackState() to better distinguish between the two types of information.
