Introducing Red5 Pro Version 3.5.0! This update introduces huge improvements in our autoscaled solution for WebRTC. We now support secure proxied Websocket calls through the Stream Manager so that you only need to install an SSL cert in one place. This simplifies large scale deployments significantly given WebRTC’s complex security requirements.

On the iOS and Android SDK side, we improved Red5 Pro's ability to receive high-quality audio and refined AV sync.

We've also included additions to our example apps like stream manager proxy publisher and subscriber examples.
