The SDP used to establish a connection in WebRTC has a non-standard dialect: Plan B. Removal timeline: M93: Exception thrown in Canary. M96: Exception thrown in Beta and Stable. There is a Deprecation Trial to avoid the exception until May 25, 2022 (https://developer.chrome.com/origintrials/#/view_trial/3892235977954951169). The End Date was previously December 29. To get new new End Date, a new OT token is needed. First version with Plan B removed: M102.
Plan B is Chromium-only and has compatibility issues with for example Safari and Firefox. Some features are not available in Plan B. Unified Plan has been shipped-by-default since M72. WebRTC is now a W3C Recommendation.
