Noteworthy Changes:

  • IPV6 support in WebRTC
  • Multiple BUNDLE groups
  • Tab audio capture has landed pref'd off. Plan is to extend it to screen capture and pref on screen capture in Fx44.
  • Improved ability for applications to monitor and control what devices are used in getUserMedia (DeviceId constraints and enhanced support)
  • Prefs for controlling ICE candidate generation and IP exposure
  • Hooks for extensions to allow/deny createOffer/Answer
  • Web Audio performance improvements
