Apple just dropped a surprise firmware update that adds AirPlay 2 support to the AirPort Express. Firmware Update 7.8 supports the 2012 AirPort Express 802.11n model.
AirPlay 2 is Apple’s streaming audio protocol that supports playing from multiple devices in multiple rooms without any latency issues. AirPlay 2 is available on Apple’s HomePod, Apple TV, and speaker products from other companies such as Sonos.
There were hints in iOS 12 betas that AirPort Express might get AirPlay 2 support, but until today the mini Wi-Fi router seemed to be left in the past. Seeing support now is both welcome and a surprise since Apple stopped making its AirPort Basestation products earlier this year.
