Items

 * Music Disc
 * Added a new music disc from Lena Raine titled "otherside".
 * Can be found on rare occasions in stronghold corridor chests, or much more rarely in dungeon chests.
 * Has a blue and green color to the ring area of the disc.

World generation

 * Caves
 * Completely overhauled.
 * Now stretch down to Y=-59.
 * The caves now generate in 2 layers of different stone bases depending on the depth.
 * The layer above Y=0 is made up of regular stone.
 * Stone transitions to deepslate from Y=0 to Y=-7.
 * Deepslate completely replaces stone from Y=-8 to bedrock.
 * Certain types of ores and structures still generate in the deepslate layer, as well as tuff and gravel.
 * Dirt, diorite, granite and andesite do not generate in this layer.
 * Biomes such as the dripstone caves and lush caves now generate in the underground.
 * Contain aquifers, bodies of water with different heights, independent of sea level (Y=63).
 * Aquifers below Y=0 sometimes generate with lava instead of water.
 * Improved old caves to blend in with the new generations of caves better
 * New noise caves, coming in 3 forms, "cheese", "spaghetti", and "noodle".
 * Cheese caves have large stone towers stretching from the bottom of the cave to the top, and are often large enough to allow safe elytra flight.
 * Spaghetti caves are long, thin caves that have small aquifers and are more similar to original caves.
 * Noodle caves are thinner, squigglier, and more claustrophobic variants of spaghetti caves.


 * Mountains
 * Come in 6 sub-biomes:
 * Meadow
 * A grassy elevated biome that looks like a flowery and colder plains, with an aqua grass color and dark blue water color.
 * Generates in plateaus and the lowest layers of some mountains, usually near plains and other temperate biomes.
 * Contains grass, tall grass, dandelions, azure bluets, cornflowers, poppies, daisies and alliums

 * Grove
 * Generates in the slopes of a snowy mountain when next to forested biomes.
 * Reminiscent of a snowy taiga with a surface of snow blocks and powder snow, instead of grass blocks.
 * Rabbits, wolves, foxes, sheep, pigs, chickens and cows spawn in this biome.
 * Pillager outposts can generate in this biome.
 * Snowy Slopes
 * Generates in the slopes of a mountain when next to plains and snowy tundra.
 * Covered in snow, snow block and powder snow.
 * Only rabbits and goats spawn in this biome.
 * Igloos and pillager outposts can generate in this biome.
 * Jagged Peaks
 * One of three biomes that generate in the mountain peaks.

 * Pillager outposts can generate in this biome.
 * Frozen Peaks
 * One of three biomes that generate in the mountain peaks.
 * Covered in snow, snow blocks, ice, and packed ice.

 * Only goats spawn in this biome.
 * Pillager outposts can generate in this biome.
 * Stony Peaks
 * One of three biomes that generate in the mountain peaks.
 * Covered in stone, gravel, and strips of calcite.

 * Copper ore veins mixed with granite and blocks of raw copper generate above Y=0.

 * Upgrading of old worlds
 * Terrain from new chunks will now blend with existing terrain from old chunks. Any player-made structures in these chunks will be either intact, buried, or deteriorated.
 * The old bedrock layer between Y=0 and Y=4 in old chunks gets replaced with deepslate.
 * If there is bedrock at Y=0, lower places in old chunks will be filled with deepslate and caves.
 * A new bedrock layer is placed at Y=-64.

 * Lapis lazuli ore attempts to generate twice: once, as a spread between the altitudes of Y=32 and Y=-32, peaking at an altitude of 0; and evenly between the altitudes of Y=64 and Y=-64, generating buried like ancient debris.
