Hi,

>I feel very strongly that we must reference a stable version or else there is no way to know what is reviewed. The w3c spec was not approved before and was a draft
>so it was hard but at this point I think the REC version is the correct references. 

I don't object to referencing a specific version - I actually agree.

My question is why JSEP uses an INFORMATIVE WebRTC reference WITH a version, while other RTCWEB RFCs use NORMATIVE WebRTC references WITHOUT a version...

>So it should reference https://www.w3.org/TR/2021/REC-webrtc-20210126

RFC 8829 references https://www.w3.org/TR/2020/PR-webrtc-20201215/. I just want to verify that there is no text etc in 8829bis that is not aligned with 20210126.

Regards,

Christer
