Yes, but the point is that you could achive everything you can now before this update, just with the DS Audio App I.E. Select music with your iPhone/Touch with the App over WiFi selecting music from your NAS and sending it via WiFi to an Apple TV2 (or just to your device) conected to your Amp via Optical.
The issue has never been for the NAS to see the Apple TV2 but that the Apple TV2 cannot see the NAS as a stand alone drive from which your could stream music/movies via iTunes and not Audio Station, control it with the Apple TV2 remote without the need for an iPhone/Touch device to control it.
