Larger ore veins can now be discovered in cave systems, and the distribution of ore throughout a world has been adjusted to compensate for the new height and depth caps. Aquifers are another new feature in caves, leading to bodies of water such as flooded caves and underground lakes.Ĭhanges to caves also come with a few extra adjustments. These are 'Cheese Caves,' which are large and open 'Spaghetti Caves' which are wide and tunnel downward and 'Noodle Caves,' which are narrow and winding. Cave generation is also being tuned overall, with specific cave biomes able to appear directly underneath the surface and three types of noise caves also being discoverable. Two additional biomes can now be found both above and underground: Jagged Peaks and Meadows, as well as Lush Caves and Dripstone Caves, respectively. RELATED: Minecraft Biomes That Deserve Updates After Caves and Cliffs Mojang says this will result in new, unique biome placements such as deserts appearing at the top of hills.

For example, Minecraft's mountains can now reach a maximum height of 256 blocks, and biomes aren't always going to determine the local terrain shape or elevation.

New terrain is being implemented to coincide the changes to world height and depth.
