New Overworld Biomes

Dripstone Caves

Frozen Peaks

  1. Smooth mountain peaks with ice and snow
  2. Spawns Goats and Yeti. Wait, no, actually it’s just Goats

Patch Notes & Changelog Minecraft 1.18

Patch Notes & Changelog Minecraft 1.18

New Ore Distribution

  1. Changed ore generation to match the new world height, and to add more strategy to mining. There is no longer a single height level that is best for all ores – you need to make tradeoffs!
  2. Iron Ore generates below height 72, with a strong bias towards height 16. Iron Ore also generates above 80, with more Iron Ore as you go higher.
  3. Copper Ore generates between height 0 and 96, with a strong bias towards height 48. Copper Ore generates in larger amounts in Dripstone Caves Biome.
  4. Lapis Lazuli Ore generates below height 64, with a strong bias towards height 0. However, Lapis Lazuli Ore below height -32 or above height 32 cannot generate exposed to air. It will either be buried or inside water.
  5. Coal Ore generates above height 0, with a strong bias towards height 96 and above. Coal Ore has reduced air exposure, so you will find more Coal Ore buried or underwater than exposed to air.
  6. Gold Ore generates below height 32, with a strong bias towards height -16. Extra Gold Ore generates below height -48. Extra Gold Ore can be found in Badlands biomes above height 32.
  7. Redstone Ore generates below height 16. Redstone Ore generation gradually increases as you go below height -32 and further down.
  8. Diamond Ore generates below height 16, with more Diamond Ore the lower you go. Diamond Ore has reduced air exposure, so you will find more Diamond Ore buried or underwater than exposed to air.
  9. Emerald Ore generates above height -16 in mountainous biomes, with more Emerald Ore the higher you go. Emerald Ore below height 0 is very rare!

Noise Caves and Aquifers

  1. Noise caves are a new way of generating caves, providing more natural variety. They can get really huge sometimes! Noise caves come in three flavors:
    • Cheese caves: Like the holes in swiss cheese. These often form caverns of various sizes.
    • Spaghetti caves: Long squiggly tunnels, sometimes wide like tagliatelle
    • Noodle caves: Thinner, squigglier, and a more claustrophobic variant of spaghetti caves
  2. No, they aren’t loud. The “noise” part of noise caves is a technical term and has nothing to do with sound.
  3. The old cave carvers and canyons still generate, combining with the noise caves to form interesting cave systems
  4. As with carvers, noise caves form cave entrances where they intersect the surface
  5. An aquifer is an area with the local water level, independent of sea level
  6. Aquifers are used during world generation to generate bodies of water inside noise caves
  7. This sometimes results in large underground lakes
  8. They can also form inside mountains and on the surface
  9. Aquifers below y0 will sometimes be lava aquifers instead of water aquifers
  10. Magma Blocks sometimes generated at the bottom of underground bodies of water
  11. Underwater cave carvers and underwater canyons have been removed since aquifers are used to generate water in caves instead


  • Previously, any collision with a block would reduce sprinting to walking. Now, for very minor angles of collision with a block, players retain their sprint. For larger angles of collision, the old behavior is retained.

Upgrading of Old Worlds

  1. The transition between new and old terrain is less “cliffy”
    • Will surface height blend? Yes.
    • In Minecraft 1.18, will biomes blend? Yes.
    • Will caves blend? Your mileage may vary.
  2. In old chunks, if there is any Bedrock at y=0, the sections below non-air blocks will be filled with new generation
  3. The old Bedrock between y=0 and y=4 in old chunks gets replaced with Deepslate
  4. A new Bedrock layer is placed at y=-64

World Generation What Was Added In Minecraft 1.18

  1. Generation range and build limits have been expanded by 64 blocks up and 64 blocks down, to a total range of 384 blocks
  2. Underground features, structures, and caves generate all the way down to y-64
  3. Exception: Diorite, Granite, Andesite, and Dirt will not generate below y0
  4. Tweaked size and positioning of Diorite, Andesite, and Granite generation
  5. Dripstone clusters can no longer be found in normal caves, only in Dripstone Caves biomes
  6. Starting from y8 and below, Deepslate gradually replaces all Stone
  7. Deepslate blobs no longer generate above y0
  8. The terrain shape and elevation varies dramatically, independently from biomes
    • For example, forests and deserts could form up on a hill without needing a special biome just for that
  9. Less Diorite, Granite, and Andesite generates above y 60
  10. Strips of Gravel can generate on stony shores
  11. Swamp trees can grow in water 2 blocks deep (instead of just 1 block deep)
  12. Removed water lake features, aquifers provide local water levels
  13. A bunch of biome variants with similar features but different shapes have been merged into one since the shape is controlled independently now
  14. Renamed some biomes
  15. Geodes now only generate up to height 30


  1. Added an accessibility option to stop the sky from flashing during thunderstorms
  2. Added fall_from_height and ride_entity_distance advancement triggers
  3. Changed nether_travel to match other similar triggers
  4. Added an option to specify the audio device used by the game
  5. Replaced light and barrier particles with block_marker
  6. Replaced the client bound chunk update network packet with another one that additionally contains light update data
    • The separate light update packet still exists and is sent when a light update happens without a chunk update
  7. New video setting called “Chunk Builder”
  8. Changed the prioritization order of the chunk rendering pipeline
    • Unrendered chunk holes in the world should not appear anymore while flying fast with high render distance
  9. View distance now causes chunks to load cylindrically around players instead of in a square
  10. Added “Toggle Sprint” and “Toggle Sneak” to the Controls settings
  11. Moved Keybinds out to their own settings screen, accessible from Controls
  12. Information about the world generation noise is now displayed on the debug screen
  13. Added illageralt, rune-like font from Minecraft Dungeons (currently only usable via commands)
  14. Added startup option –jfrProfile and command jfr to start profiling with Java Flight Recorder as well as a few custom events
  15. Loot table functions set_contents and set_loot_table now require a type field with a valid block entity type

More Technical Changes

  1. Added new loot table function set_potion
  2. The maximum amount of background threads are increased
  3. Worlds last saved before Minecraft 1.2 (pre “Anvil”) can no longer be opened directly
  4. Data pack format has been increased to 8
  5. Resource pack format has been increased to 8
  6. –report option in the data generator now creates reference files for the entirety of the worldgen, instead of just the biomes
  7. Removed length limits for the scoreboard, score holder, and team names
  8. Standalone server.jar now bundles contains individual libraries instead of being a flat archive
  9. Size limit for server resource packs has been increased to 250 MB
  10. Servers can now set property hide-online-players to true in order to not send a player list on status requests
  11. A new setting called “Simulation Distance”
  12. Mob spawners can now override light checks for spawning
  13. Added telemetry for world loading
