1.7.0 fixed the time it takes to get into a ingame(if you get into a server now, it's almost guaranteed you get ingame), reduced ingame lagg(including stuff taking forever to get into your backpack). Added a few new small bugs, but hey, DayZ has been suffering from server problems ever since it boomed, if he finally got rid of that it means he can actually start working on the game, instead of on the servers.
