Latest Edition of Flight Simulator

Hi
I would be very grateful for your help. I am currently using Flight Simulator X Deluxe Edition 2006 and I have now flown every commercial airliner in it I.E 737/800 737/400 and a few Airbus jets, learjets and bombardier. The problem is I want to fly the latest airliners. Is there a more up to date version of Flight Simulator or an expansion pack to add the latest commercial jets? As I say any help would be much appreciated.
