Noteworthy Changes:

Full-duplex audio is now turned on for all primary supported platforms by default:

• bug 1333438 Pref on full-duplex for Android
• bug 1325577 Use aggregate devices API in audiounit backend
  • This means that issues with drift when using full-duplex on Mac should be solved, and full-duplex will be the default on Mac. (It became the default in linux a number of releases ago, and the default on Windows in 53)

bug 1335939 Pref on ICE TCP support

bug 1340718 If a audio device (Citrix) disappears and fails on re-open attempts, output can be hung until restart You never want to leave the audio system hung, and this fixes a problem for a major user of 52ESR. (Fix uplifted to 53 and 52ESR)

bug 1320170 Screensharing previews are broken in current nightlies

bug 1300665 Missing support for RTP toffset, abs-time header extensions Note: we did not yet add support for 3gpp:video-orientation

bug 1219468 Replace PRLogModuleInfo usage with LazyLogModule in webrtc This means that all logging can be done through MOZ_LOG (NSPR_LOG_MODULES is no longer needed); see [Media/WebRTC/Logging]
