IFI is currently working on Master Code 11,
it fixes an issue with PWMs 6-12 where the pwms would become active for a fraction of a second, when the robot is not powered in disabled mode (the way it is normally powered at FIRST events) it will not be required for The Championships, it isn't a typo,
Hope that helps, and here is the link for update 19
