Surprise, the AirPort Express isn’t dead! While Apple stopped selling AirPort products back in April, the company is still updating the firmware of the once beloved AirPort Express.

This firmware update is quite significant as it adds support for AirPlay 2 and the Home app. In other words, you can now plug speakers to a dusty AirPort Express and turn them into wireless speakers for your home sound system.
