Seven years and counting, Minecraft is still growing and expanding. We
thought it is about time we add something to guide you through the vastness
of the endless overworlds. Introducing the Exploration Update!
Among your villager friends, you will now find the Cartographer residing in
the library. Spend your hard-earned emeralds to obtain maps leading you to
adventurous locations such as the Ocean Monument and the new Woodland Mansion.
This procedurally generated dungeon is the home of the villager’s outcast
cousins, the Illagers. This insidious and spooky crowd will not tolerate any
trespassers in their home, so you should expect a fight when you venture
there for the mansion’s treasure.
The Exploration Update also brings the Shulker Box, an inventory-expanding
chest originating from The End itself. This box’s primary property is to
keep items inside of itself even when the box is knocked down. This behavior
is something that contraption tinkerers should find useful as well, as it
enables large amounts of items to be transported in a predictable manner.
Speaking of transporting items, Minecraft now hosts llamas! The llamas live
in the mountains and can be equipped with chests to carry items for you.
Well-mannered as they are, they will also politely form caravans whenever you
lead one in your travels.
As always there are many other neat additions in this update, and here is the
intentionally noninformative change log:
Added cursed enchantments
Added the Observer block
Added escape portals in The End
Added the Shulker Shell and Shulker Box
Added exploration maps
Added the Woodland Mansion
Added Illagers, and the Vex
Added Llamas
New command: /locate
