To reiterate, because it's rather important: Airfoil for Windows v3.6 (or later) is required for Airfoil Commander to function after this update! The bold letters mean I'm super serious, so please be sure to upgrade to that version if you haven't already.
A big hearty "thank you!" goes out to the good folks at Rogue Amoeba for their hard work making the protocol changes that allowed the above two items to happen.
And finally, there's the usual round of bug squashing and stability improving that accompanies every single update to every Android app ever. Seriously, when was the last time you looked at the details for an app update and didn't see "bugfixes and stability improvements" tacked onto the end? Airfoil Commander is proud to be absolutely no different in that regard.
Enjoy the update!
