Minecraft wiki entry for Easter_eggs, associated text: 15w14a was released as an April Fools' joke for version 1.10, when the next update was supposed to be 1.9. This "update" is called the Love and Hugs Update.[8] There was also a QR code written in the snow that generated in a superflat world that, when scanned, reads "Minecraft 1.9: The Combat Update". Swords were replaced with "hearts". The only world name available was "There can only be one". Survival was called "Existence". Players were also unable to take damage from The Void.
