While there are some library updates in this release, they aren't major.
The main feature added to this version is a custom API that allows the following website to access CORS-protected websites. It also allows to access cross-mixed remote resources.
The point of this all is to allow users to use IP cameras (mjpeg-based) as camera sources for VDO.Ninja. So for example you can share a local IP security camera with others on the Internet, via WebRTC/VDO.Ninja, bypassing firewalls and with optimized bandwidth controls.
