The controller connected to wifi instead of the device you were playing on. That meant it could send inputs directly to the game servers in the cloud (without knowing anything about the device you were playing on) and not worry about extra hops or performance bottlenecks in trying to route through e.g. smart TVs, Chromecasts, laptops, etc. This update allows it to pair with devices like a normal controller, so input from the controller will be sent to that device instead of some cloud server.
