Diablo III Patch 1.0.6 - v.188.8.131.5200
Fixed an issue that allowed players to bypass the one-second trade timer when exchanging items via the Trade window
Fixed an issue that caused the same item to occasionally drop for players using Threatening Shout with the Grim Harvest rune.
it's a new number because it not longer fixes issues with patch 1.0.5 or fixes isues they wanted to fix with 1.0.5. Also the stuff we can't see (the login changes...ect) are big (for blizzard) The numbers are more for them than us
