I think Flex libs (mx.geom.Transform) should be updated to work with the latest versions of AIR. From the mobile perspective, it doesn't make much sense to support older ones as you can't publish apps if you are lower than AIR 32 for iOS or AIR 33 for Android.
I am not sure if there is any similar issue for desktops and web. -- Sent from: http://apache-flex-users.2333346.n4.nabble.com/
