*Early, Mid, and Late War MAs. The latter is split in two and usually houses about 250 people in each one. The other two range between 8 and 50 players.
*Capture system changed. They're testing a new system where you must capture bases in a certain order. Also testing a system where you win by having 90% of the fields you stsrted with plus at least 33% of the fields each of the other teams started with.
*ENY effects. Previously gave a side with far greater numbers a limit on the "goodness" of aircraft they could fly. Testing a new system where you must either wait until your country shrinks or switch sides to fly if you're on the larger country.
*New planes/vehicles; B-24, T-34/76, Spitfire Mk 8 and 16, 109G-10, 109K-4, P-47N, P-38G, P-38J, F4U-1A.
*"Redone" planes that look more spiffy; B-17, Spitfires, 109s, P-51s, P-47s, 190s, Corsairs.
That's all I can think of.
