I entered the U.S. at Newark this past Thursday via Global Entry, and the same thing happened to me. I had no notice about the change, so it surprised me that the kiosk took my (unflattering) picture and spit out the form right away.

I had food to declare, so I verbally declared it to the officer who was manning the exit from the Global Entry machines. He said the food I had was okay, and that was the end of it.
