World of War Planes (brought to you from Wargaming the makers of World of Tanks) is currently in closed beta and have just rolled out their latest update: 0.3.3.1. While not as symmetrical as 0.3.3.0, updates are always nice.
With this update a number of in game bugs have been fixed, a new colour scheme added to the UI, the rewards for hitting ground and air targets has been balanced and the costs to repair your battle worn and beloved aircraft have been lowered.
New players are being accepted into the game daily so for your chance to play while the testing continues sign up at the official site: worldofwarplanes.com
