To Apple's credit, they have released fairly recent firmware for all their airport devices, even adding Airplay 2 support to (either 2nd or 3rd gen?) Airport Express' that had the hardware to support it, despite the devices not being mfged anymore (for many years) and the entire product line discontinued. Fwiw, I just used a 1st gen Airport (>$20) as a wifi to ethernet bridge to get a GoldenTee machine online for a client. They also work great as a wireless airplay receiver for older stereo equipment using the 3.5mm output from the Airport!
