Main changes, other than those already posted and a couple of hints:
1) Best bogs are in the Museum - your race ticket gets you in for free.
2) The bank inside the track on Karting Nord has disappeared
3) Good spectating at the Porsche curves
4) Mulsanne and Arnage are an utter nightmare to park in - pick your time carefully.
5) Most of the old stands have been demolished and replaced by new ones on the start/finish straight. New stands at the new Esses.
Have fun
