v0.13.3

Region aware routing

Introducing region-aware routing. When configured, LiveKit could route traffic to nodes that are closer to the end user. See multi region support #135 #141 (thanks @bekriebel)

Recording revamp

We've revamped our recording capabilities so that it's close to a GA release. Notable changes include RTMP simulcast support, and moving the pipelines to GStreamer from FFmpeg. Requires livekit-recorder v0.3.1 or higher #137

Opus DTX support

Opus DTX is enabled by default in this version, significantly reducing audio bandwidth utilization.
