===<big>'''IMPORTANT:'''</big> Simulcast landed and is pref'd on ===

We landed our implementation of simulcast.  This should not impact non-simulcast use cases.  '''If you think you've found a problem or a regression, please let [mailto:mreavy@mozilla.com Maire] (mreavy on irc) know as soon as you can. ''' (See {{Bug|1230197}}, {{Bug|1210170}}, {{Bug|1231507}}, {{Bug|1242203}} for details on the landing.)   

Between now and release: If we run into problems we can't easily solve or if we're concerned about the quality/stability of WebRTC calls (especially for any non-simulcast use cases) as we test during the Dev Edition and Beta cycles, '''we may pref off before Release. Please help us test.'''

* Landed full duplex support for pulse audio (Linux) in WebRTC.  (See {{Bug|1221587}}, {{Bug|1241476}}, {{Bug|1221576}}.)

** '''Feature is currently pref'd off, but we may pref on during the Dev Edition Fx46 cycle, depending on how well testing in Fx47 goes.'''  

* Landed packetization code necessary to pref on VP9 in WebRTC.  (See {{Bug|1237023}})

** '''Feature is currently pref'd off, but we may pref VP9 ON during Dev Edition Fx46 cycle, depending on how Nightly testing in Fx47 goes.'''   

* Rewrote MSG shutdown code to be less fragile.  (See {{Bug|1239873}}.)

** This means a number of intermittents should go away and shutdown should be more reliable.

* Added RTCRtpReceiver and fire ontrack for remote tracks (See {{Bug|1232082}}.)

* Fixed the label property on a media stream track for gUM-based Media Streams (See {{Bug|866513}}.

* Implemented echoCancellation, mozAutoGainControl and mozNoiseSuppression gUM constraints  (See {{Bug|987186}}.)\

* Fixed getting microphone share permission when camera share permission is pending and vice versa  (See {{Bug|1224766}}.)

* Re-enabled all disabled WebRTC e10s tests.  (See {{Bug|1234363}}.)
