When a game is in Alpha players often find and exploit the mechanics of the gameplay that maybe the developers haven't yet had the time to fix or fully implement properly yet. One part of the popular game DayZ (in which you must survive the attacks of zombies and often the other players) that has been exploited since its early origins as an add-on to the ARMA 2 game is the ability to leave and quickly rejoin a game if you didn't like the server or spawn location you landed in. With the next patch to the standalone game though, such things will quickly lead to players being 'timed-out' for a short while to stop this from happening so often.
The line of the patch notes that refers to this reads thus: “Login: Player queuing system introduced. Penalty waiting time added for switching server or disconnecting a server quickly.” which seems to allow breathing room for the random disconnects that happen to every player, especially during the Alpha and Beta stages.
Other highlights of this patch, which is still in the Experimental stage for the moment, include that defibs now work on players with less than 500 units of blood, morphine can now fix broken legs and both machetes and crafting knives can open cans, which should be a relief for those players who find it hard to scavenge any can openers in the wilds of the game.
The last patch implemented to DayZ put an end to the infamous 'backpack-ception' part of the game which allowed players to carry as many filled backpacks with them as there were spaces in a backpack.
