Hi Nils,
thank you very much for the response and the links provided. Knowing to
also check on the published Release Notes will be helpful.
Regards,
Juan

I'm aware of Firefox Platform Status
(https://platform-status.mozilla.org/) but I'd like to know if there
are other sources of information for updates on the Firefox WebRTC
features; maybe some place where announcements are made just like the
PSAs done in the discuss-webrtc group
(https://groups.google.com/forum/#!forum/discuss-webrtc
<https://groups.google.com/forum/#%21forum/discuss-webrtc>)
For example, a month ago I wanted to track implementation of the
RTCRtpSender.replaceTrack() method. For Chrome this was easy: their
Platform Status website had (still has) an entry called
"RTCRtpSender.replaceTrack" where it stated that the planned release
version would be 65; and also the discuss-webrtc group has
(coincidentally today in the first position) an entry named "PSA:
replaceTrack() shipping in M65", where they give more detail.
However, in Mozilla's Platform Status website there are no results
for either "replaceTrack", "RTCRtpSender", or
"RTCRtpSender.replaceTrack". There are not many useful results either
in this google group. However I'm pretty sure the replaceTrack
feature has been developed between Firefox versions 58 and 59: in
Firefox 58, sender.replaceTrack(null) wasn't supported, but in
Firefox 59 this call started working. So, support for a 'null'
argument has been added.
I just would like to know if there would have been some resource
where I could have known ahead of time (say a month ago) that this
feature was going to be added to Firefox 59. Same for other similar
features.
Let me start with pointing out that we try to publish Firefox WebRTC
Release Notes shortly after a new version of Firefox gets started. For
example for Firefox you can find them here
https://wiki.mozilla.org/Media/WebRTC/ReleaseNotes/59
And for the current Firefox Beta 60 they are here
https://wiki.mozilla.org/Media/WebRTC/ReleaseNotes/60
In the future I’ll try to send out emails to this list when new
release notes are available.
Normally I would also point you at MDN for documentation of features
in Firefox. But it seems that the documentation for replaceTrack() is
actually missing in there - I notified our MDN folks about it.
In terms of your specific issue my guess is that it is a side effect
of Transceivers becoming available in Firefox 59, and not specific
work on replaceTrack().
And lastly we encourage everyone working on or with WebRTC to always
test with Firefox Nightly or at lest Beta to ensure their products
keep working with browser implementations which try to keep up with
the changing WebRTC spec as good as they can.
Best regards
Nils Ohlmeier
