+**Bug Fix**
+* When built for AirPlay 2, ensure the hexadecimal string that prefixes the AirPlay 1 Service Name in the Bonjour text strings matches the AirPlay 2 Device ID. For example, if the Service Name is `Kitchen` and the AirPlay 2 Device ID is `b8:2f:eb:d7:85:df`, the AirPlay 1 Service Name should be `B82FEBD785DF@Kitchen`. (When built for AirPlay 1, the hexadecimal prefix is simply a hash of the Service Name.)
