I don't think they added any sensor ports - still just the four. But now it comes with a gyro sensor built into the brick.
The 4th motor port is huge for some things. It was almost impossible to build a holonomic drive with only 3 motor ports. Now you can have two drive motors and two for manipulators, so you can have a simple articulated arm with a motorized grabber. But I'd sure love to have six of each port.
