What does the 0.7.0 in the doge camo mean?

churchill50: If I remember correctly, the Doge camo was originally offered as a reward in an event. The event gave you an opportunity to log onto a server running a past instance of the game so you could relive the nostalgic days of WoT now gone. And, if I remember correctly, that server was running a patch 0.7.0 version of the game. I'm pretty sure that's the reason, but I'm not totally sure, so please someone correct me if I'm wrong.
