21w08a is the eleventh snapshot for Java Edition 1.17, released on February 24, 2021,[1] which renames grimstone to deepslate, adds deepslate ores, and makes changes to cave generation.

Additions

Blocks

Cobbled deepslate

  • Drops from deepslate when mined with a pickaxe without Silk Touch.
  • Functions identically to cobblestone and blackstone in that it can be used to craft basic tools, furnaces, and brewing stands.
  • Is used to craft all the deepslate variant blocks instead of regular deepslate.
  • Renamed regular deepslate stairs, slabs and walls to cobbled variants.

Deepslate ores

  • Added deepslate variants of diamond, iron, gold, lapis lazuli, and redstone ores.
  • Take twice as long to mine as normal ores.
  • Have the texture of deepslate replacing the normal stone texture.
  • Take place of ores that generate in deepslate.
    • Normal stone ores may still generate deep underground if they replace a different block, such as tuff.
  • Can be used in blasting and smelting recipes like normal ores.
    • These recipes can be unlocked in the recipe book with deepslate ores as well.

Smooth basalt

World generation

Crack carvers

  • Deep, long cracks in the ground that are thinner and straighter than canyons.[2]
  • Can reach over 90 blocks in depth.
  • They are very similar to canyons in Bedrock Edition.

General

Tags

  • Added the deepslate_ore_replaceables block tag.
    • Contains deepslate.
  • Added the diamond_ores, iron_ores, lapis_ores, and redstone_ores block and item tags.
    • Contain the normal and deepslate variants of each ore type.
  • Added the stone_ore_replaceables block tag.
    • Contains stone, granite, diorite, andesite, and tuff.

Deepslate

  • Renamed from "Grimstone".
  • Is no longer used to craft or repair any blocks or items.
  • Has new unique breaking, placing, and footstep sounds.
  • Can only be mined with a Silk Touch pickaxe.

Lava

  • Now replaces air below Y=-55.

Spore blossoms

  • Particles now appear in the air around the block.

World generation

Amethyst geodes

  • Can no longer generate fully in midair.
  • The tuff layer has been replaced with smooth basalt.

Andesite

  • No longer generates below Y=0.

Caves

  • Tweaked cave sizes.[3]
  • Ravines and regular cave carvers now generate below Y=0.
  • Added more variation to carvers.[4]
  • Caves are now more filled with water.

Glow lichen

  • Generates almost twice as often.[5]

Lava

  • Once again generates at the bottom of the world starting at Y=-54.

Water

  • Water springs can now generate below Y=0.
Ore distribution changes.

Mineral distribution

  • Ore distribution has been changed again.
    • Iron now generates below Y=0, but in smaller blobs and not as frequently.
      • This was determined to be a bug, which was fixed in snapshot 21w08b.
    • Gold is a little more common, but with 50% of blocks exposed to air skipped.
