			* It has previously been rumored that Notch did not use [[Minecraft:w:LWJGL\|LWJGL]] for ''Minecraft'' until after this version. However, this is a confusion from the fact that he switched from pure Java to LWJGL ''specifically'' for a small game he was working on for a game competition during the middle of July 2009,<ref>{{twon\|143020675/i-think-i-know-what-game-im-making\|I think I know what game I’m making\|July 16, 2009}}</ref> and ''Minecraft'' has actually used LWJGL from the very beginning of its development, including the previously unreleased [[Minecraft:pre-Classic]] versions.
