Command format

 * Syntax
 * Added an alert telling the player to use item names when you spawn item in using its ID, due to soon becoming deprecated.

General

 * Achievements
 * The "Diamonds to you" achievement can now be obtained by throwing a diamond at a zombie with the "CanPickUpLoot" NBT-tag.


 * Main Menu
 * Added an alert in the main menu warning the player of a change in the far future, which will result in Minecraft requiring an OpenGL feature set version of 2.1 or higher.
