On the Road to WebRTC 1.0, Including VP8
Safari 11 was the first Safari version to support WebRTC. Since then, we have worked to continue improving WebKit’s implementation and compliance with the spec. I am excited to announce major improvements to WebRTC in Safari 12.1 on iOS 12.2 and macOS 10.14.4 betas, including VP8 video codec support, video simulcast support and Unified Plan SDP (Session Description Protocol) experimental support.
RTCQuicTransport Coming to an Origin Trial Near You (Chrome 73)  | Blog  | Chrome for Developers
What? The RTCQuicTransport is a new web platform API that allows exchanging arbitrary data with remote peers using the QUIC protocol. It’s intended for peer to peer use cases, and therefore is used with a standalone RTCIceTransport API to establish a peer-to-peer connection through ICE. The data is transported reliably and in order (see section below for details on unordered & unreliable delivery)
