Hello Minecrafters!


Today we have exciting news!  Make sure to remember the date of June 8th as that's when the Caves & Cliffs part one update is planned to be released!  Until then, Mojang Studios is hard at work squashing the last remaining bugs, and any help from the community to find these before release is much appreciated!
