These are patch notes relating to all of the new features added in the Minecraft 1.18 update.
Increased world height and depth
Overworld height and depth for new and existing worlds has been extended to y320 and y-64, opening up more space to explore and build in
World blending
Players can now update existing worlds to include the new overworld height dimensions and world generation features. See our for more details
The bedrock layer at y0 below saved chunks will be replaced with Deepslate and feature new cave generation underneath
Biomes and terrain generating across new and existing chunk borders will blend seamlessly, creating natural-looking environmental transitions
New terrain and mountain generation
Terrain shape and elevation is no longer always determined by biome, resulting in new biome placements such as deserts on top of hills
Mountains are taller than ever and can now generate up to a maximum height of 256 blocks
New biomes, 3D biome generation, and biome distribution
Added 3D biomes - cave biomes can now generate directly below surface biomes
New cave and mountain biomes added, including Jagged Peaks, Meadows, Lush Caves and Dripstone Caves
New cave generation
Added noise caves - the three primary types of noise caves are large, open Cheese Caves, wide, tunnelling Spaghetti Caves and the narrow, winding Noodle Caves
Added aquifers - these create local level bodies of water such as flooded caves or underground lakes
Ore distribution and large ore veins
Added large ore veins - these long formations stretch through cave systems and contain larger deposits of ore than the clusters usually found underground
Ore distribution has been adjusted to compensate for the new world height
Mob spawning
Monsters will now only spawn in complete darkness. Players can spawn-proof dark areas such as caves using light sources
New music
Added new music by Lena Raine and Kumi Tanioka
Added a new music disc from Lena Raine titled "otherside". This can be found rarely in Stronghold corridor chests or much more rarely in Dungeon chests
Mobile players: To hear the new music, you will need to download the updated Minecraft Original Music Pack, available FREE from Marketplace
New achievements/ trophies
Caves & Cliffs - Free fall from the top of the world (build limit) to the bottom of the world and survive
Feels Like Home - Take a Strider for a loooong ride on a lava lake in the Overworld
Sound of Music - Make the Meadows come alive with the sound of music from a jukebox
Star trader - Trade with a villager at the build height limit
