Minecraft (Windows) as well as the various Pocket Editions of Minecraft will soon be receiving the Discovery Update, numbered 1.1. According to Mojang, "it’s not called The Discovery Update for no reason: there are many mysterious and wondrous things to uncover."
There are llamas, new enchantments and more on the way in the update:
Barter with a cartographer for a treasure map, sling your supplies into a llama’s pack (or into a shulker box) and embark on an epic quest to locate the dank and dangerous forest mansion! Does your route take you across an impassable river? The Enchantment of Frostwalking will solve that problem! Meanwhile, the Enchantment of Mending will keep your swordblade sharp no matter how many mobs you slay along the way. Defeat the sinister illagers who lurk within the mansion and make off with their precious loot - the Totem of Undying - and cheat death as you throw yourself into further peril!
Crafters looking for a more sedate pace of discovery will be pleased to hear you can now dye beds, smelt ingots, and build with the fancypants new blocks: glazed terracotta and concrete. And those with an even more experimental inclination, will find the expansion of Add-Ons to their liking: you’ll now be able to remix mobs’ movement properties!
According to Mojang's post introducing the update, it'll be available soon in beta testing for Android users. There is no date for the update other than "soon," and no word yet on when it will be making its way to consoles, so be sure to keep your eyes peeled for more information. They promise to reveal more about the update in the coming days.
