Just a notice if you suddenly find out your programs dont work anymore:

Note : NODE/LAP - To allow laps up to 2047 to be reported, without increasing the size of
NLP and MCI packets, the next 3 high bits of the current lap are now placed in the highest
3 bits of the Node_Lap_Hi3 member (of NodeLap and CompCar structures).

Look at InSim.txt for more information.
