New patch. Some nice changes.
Also as I thought gamma glitching at night has been fixed in the beta patch.
HOTFIX : 19 JUNE 2012
	Affected addons:
		* dayz_code		1.7.1.5
		* dayz_equip	1.3.3
		* dayz_weapons	1.3.2
	
	Developer's Note:
		* A designation of [NEW] doesn't necessarily mean a new feature, 4chan, it means a change in operation not directly related to a bug. Could be for better performance or rebalancing.
		
	Changelog:
		* [NEW]		Infected raycast for line-of-sight less often (improves performance)
		* [FIXED]	Infected can see through terrain ( https://dev-heaven.net/issues/33787 )
		* [FIXED]	Raycasting being taken from wrong body position (ensured it is from eye level)
		* [FIXED]	Infected sometimes spawn close to a player (previous check once, now up to ten times)
		* [NEW]		Infected bodies will despawn after 5 minutes of their death (improves performance)
		* [FIXED]	Sometimes infected will stand still after loosing line-of-sight ( https://dev-heaven.net/issues/33715 )
		* [FIXED]	Can dupe tent's by right clicking (forgot to close the window)
		* [FIXED]	Poor performance caused by infected search behavior (MAJOR performance increase during closed testing)
		* [FIXED]	Audibility is far to high (completely rebalanced, in line with how it was in previous updates)
		* [FIXED]	Can dupe food during cooking if click really fast (now you cannot)
		* [FIXED]	Trying to pick up a hatchet would create fake ammo (now will not)
		* [FIXED]	Hatchet takes up too much room (can now be transferred between toolbelt and primary slot through gear action)
		* [REVERT]	Hatchet now collected as an Item (toolbelt) and can be equipped to primary (gear action)
		* [NEW]		Flashlights can now be packed to toolbelt also (gear action)
		* [NEW]		New players will spawn with flashlight added to their toolbelt not backpack
		* [FIXED]	Infected sometimes not inspecting thrown items (they will walk to the location of a noise, 20-40m away)
		* [FIXED]	Unlimited Infected spawning (now has a cooldown enabled so it won't spawn too many at once)
		* [FIXED]	Melee weapon sounds non-existent/terrible (now has placeholder sounds)
