AirPlay Overhaul for iOS 9
While the changes won’t affect app developers simply using AirPlay APIs for offering users the ability to stream from within an app to an AirPlay device like an Apple TV, it will break many screen mirroring apps that tap into the AirPlay protocol for screen sharing like Reflector. The apps that are often used in education, enterprise, and within the tech world for things like screen recording and display mirroring to devices not supported by Apple.
Though developers of screen mirroring and streaming apps piggybacking on the protocol will have to implement workarounds to avoid issues with the changes in iOS 9, the overall changes appear to be a move by Apple to vastly improve device pairing and in the process improve the overall AirPlay experience across devices.
