Noteworthy Changes:
IMPORTANT: We've unprefixed the main WebRTC APIs:
- mozRTCPeerConnection
- mozRTCSessionDescription
- mozRTCIceCandidate
- HTMLMediaElement.mozSrcObject.
We will continue to support the prefixed APIs for several releases and will publish a PSA *before* we drop support for the prefixed APIs, but *please* update your implementations as soon as you can. (See bug 1155923.)
Other noteworthy changes:
- gUM now captures at 32kHz (See bug 953265.)
- MediaStream.addTrack() and MediaStream.removeTrack() are now supported (See bug 1103188.)
- HTMLCanvasElement::CaptureStream now works on mobile (Android and B2G) (See bug 1210286.)
- MediaRecorder now supports all streams you can get from APIs in gecko (See bug 1182426.)
- Screensharing now respects the framerate passed in via GUM constraints (See bug 1211658.)
- Web Audio performance improvements (See bug 1200579, bug 1205540, bug 1205558, bug 1207003, bug 1210280, bug 1214493)
