What about to give us a way to disable update message?

Okay, guys. I'm very happy that 0.8.5 is released. I'm very happy that this game is continues to develop.

But I'm not happy that when I tried to play locally today with my friends I had this annoying floating message about update. It really distracts us, and we have not too good internet connection to download your update right here and right now. Maybe you will give us an easy way to disable it for now?

Try this:
(before you need  to open the console via "~"-key or "SHIFT+ESC" while running the game)
write at the console (in the game):

Code:

menu_updatecheck_getpacks 0
seta menu_updatecheck 0

restart the game.
