Does Teensy 2.0 need decoupling caps on the power pin?

I always use a 100nF decoupling cap on all MCU's, but maybe it's already incorporated on the Teensy 2.0 board, I don't know.

Looking at the Teensy 2.0 schematic there is a 1μF electrolytic capacitor between the USB 5V input and ground, and another one ready for use if the optional 3V3 regulator is added.
