• New release schedule – a fresh minor version will ship on the last weekend of every month.

• Multi-codec negotiation lets peers negotiate for media sections with different audio/video codecs.
• ICE improvements
  • Add a ufrag extension to generated candidates.
  • ToICE converts webrtc.Candidate to ice.Candidate.
  • New APIs to add and retrieve ICE extensions.
  • AddCandidate rejects candidates from old generations.
