# WebRTC Definition Notes ## The WebRTC specification The WebRTC specification is currently a work in progress, but it has been implemented at a basic level in recent versions of Chrome, Opera and (to a lesser extent) Firefox. The latest version of the specification can be found at https://www.w3.org/TR/webrtc/. This particular set of definitions does not use any vendor-specific prefixes. Instead, you should probably use [adapter.js](https://github.com/webrtc/adapter). The definitions track the currently published working draft. Deprecated features are dropped.
