API and Breaking Changes

• Added hls.loadingEnabled (toggled with hls.startLoad() and hls.stopLoad() - for internal use)
• Added Events.EVENT_CUE_ENTER (for internal use)
• Added levelInfo: Level to LevelLoadingData and LevelLoadedData event data
• Added track: MediaPlaylist to TrackLoadingData and TrackLoadedData event data (audio and subtitle events)
• Added withoutMultiVariant: boolean to LevelLoadedData event
• Added LevelDetais.expired: boolean readonly getter
• Added LevelDetais.requestScheduled: number property (for internal use)
• Added readonly Fragment.bitrate and Fragment.byteLength getters
• Several Fragment properties have been changed to readonly getters or getter/setters: get baseurl(), get/set stats(), get/set programDateTime(). This impacts serialization and extension of these properties (stats will not be copied with spread operator or Object.assign).

If you are upgrading from version v0.14.17 or lower, see the MIGRATING guide for API changes between v0.14.x and v1.0.0.
