The one above - which was not raced - was quite extreme, without the uppermost flap. This reduced downforce dramatically.
They also tried another new design (below) with two different options of flaps tested by the drivers: one with a cut-in the top flap (inset), which they eventually raced, and another with a new flap. The leading edge of both these wings had two stiffening points to maintain rigidity and avoid flexing.

Bringing three wings to Monza shows that Toro Rosso are pushing hard. The wings have limited use beyond this race, possibly only in Mexico, which looks set to be a high-speed circuit.
