Data version


20w48a is the third snapshot for Java Edition 1.17, released on November 25, 2020,[1] which adds dripstone blocks and pointed dripstone.



Dripstone Block
  • Decoration block.
  • Does not generate anywhere currently, is only available from the creative inventory.
Pointed Dripstone
  • Can be placed on the floor or ceiling, creating stalagmites or stalactites respectively.
    • Can be combined to form longer stalactites and stalagmites.
  • Stalagmites break if not attached to something below, and hurt entities which fall on top of them.
    • Enemies that fall on the stalagmites deal three times more fall damage
  • Stalactites fall if unsupported, and hurt entities they fall on.
    • Damage is relative to height: For example, one falling from 2 blocks deals 2♥ of damage, and one falling from 3 blocks deal 4♥♥ of damage.
    • They drip water or lava into cauldrons if a source block is placed above the stalactite, and gradually fill the cauldron. Water drips even without any water above the block, but does not fill the cauldron.
  • Thrown tridents break pointed dripstone.

Command format[]

  • freezeDamage
    • Whether entities take damage from freezing inside of powder snow.


  • Added new freeze_immune_wearables item tag.
    • Contains leather boots, leather pants, leather tunic, and leather cap.
    • Having an item in this tag in an armor slot prevents players from freezing.
  • Added new particle types: dripping_dripstone_lava, dripping_dripstone_water, falling_dripstone_lava, and falling_drip_water.



Budding Amethyst
  • The texture has been changed. Has a more prominent "X" in its center.
Block of Amethyst
  • The texture has been changed. It is now slightly less busy, striking a middle ground between the 20w45a and 20w46a textures.
  • Can now only be placed on solid surfaces.
    • If the block a candle is placed on is broken, the candle stays floating.
Cut Copper Slabs
  • Crafting all variants of cut copper into slabs now gives 6 slabs instead of 4.
Powder Snow
  • Players in creative mode can now freeze.


  • Now show fullness as a number when advanced tooltips are enabled.
  • Right-clicking a bundle in the inventory now empties one item from the bundle.
  • Using a bundle now throws out its entire content into the world.
  • The item textures have been changed to only have one candle.
  • The texture has been changed. The gold is now more vibrant and better matches other instances of gold in the Texture Update texture.
Compass and Lodestone Compass
  • The texture has been changed. The iron is now more vibrant and better matches other instances of iron in the Texture Update texture.
Leather armor
  • Wearing any piece of leather armor now prevents freezing entirely.
  • The spyglass is now a 3D model instead of a flat sprite.
  • Using the spyglass now better anchors it to the player's "eye" when viewed in 3rd person.


Recipe Book
  • Some recipe-unlocking advancements had criteria names changed.
  • The chiseled nether bricks recipe is now unlocked by having a nether brick slab instead of a nether bricks block.


  • The snow_step_sound_blocks block tag was renamed to inside_step_sound_block.
