Support persistent licenses and offline in Shaka v2

Found many related issues to this but most of them move around shaka.media.EmeManager 
http://v1-6-2.shaka-player-demo.appspot.com/docs/shaka.media.EmeManager.html which is not found in current version of shaka player.
Was this function completely removed? If so what is the alternative  to have persistent license/licenses stored in shaka player in current API
