Though the AirPort lineup of routers has been officially discontinued, but Apple has pushed out an update for AirPort Utility for iOS, adding support for the iPhone X.

Despite being discontinued, the AirPort Express received an update a few days back that adds support for AirPlay 2 to the router. Those of you who are unaware, the Express (smallest from the AirPort lineup of routers) has a 3.5mm jack at the back, allowing users to connect a set of speakers which they can then use to play stuff using the AirPlay protocol. But now, Apple has given the router a new lease of life by adding support for AirPlay 2, allowing multiple protocol supporting speaker systems to play the exact same thing in perfect harmony.
