Juli Clover, MacRumors:
Apple in April announced that its entire AirPort wireless router lineup, AirPort Express included, had been discontinued. Apple sold the AirPort Express until available stock ran out, but it is no longer available for purchase at this time.
Because the AirPort Express was discontinued, it wasn’t clear if it would indeed gain AirPlay 2 support because Apple’s AirPort unit was disbanded, but Apple did indeed opt to introduce support for customers who are still using the AirPort Express units.
According to John Voorhees over at MacStories, this only works for the second-generation AirPort Express that looks like a white Apple TV, and it needs to be added manually to the Home app — that is, you can’t just scan it to add it. But, all told, it apparently works quite well. Kudos to Apple for continuing to support a discontinued product, though it raises the question — for me, at least — as to why they decided to no longer build a great and inexpensive combination of an AirPlay 2 receiver and a WiFi signal repeater.
