Just to continue clarifying, Minecraft 1.8 was not "leaked" per-say it is a pre-release version, and
that the distribution was authorized by Jeb.If you do download this, Notch said that he is ok with it, but make sure you download it form the reccomended "URL we are hosting". Aswell don't spam him with "
Zomg Notch this is borkenz FIZ IT FIX IT".
Along if you do encounter bugs please report them at the following address
