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.)
