Today is an important day. First, we just released two new WWI fighters for all Flying Circus: Volume I customers - Fokker D.VII and Sopwith Dolphin. They are 5th and 6th aircraft released for it, so along with the map of Arras being actively developed, we can say that Flying Circus project is progressing nicely and more than half of it is already completed. 

 Second, our Tank Crew project finally includes visible crew for two already released tanks. Since we'll be releasing four new tanks and Prokhorovka map really soon, this project is also maturing at a good pace.

 Of course, we also prepared a list of many other improvements for you:
