24w20a is the fourth snapshot for Java Edition 1.21, released on May 15, 2024,[1] which fixes bugs.

Changes[edit | edit source]

Mobs[edit | edit source]

Witch
  • Now always drops 4–8 redstone dust on death.
    • This is to improve the viability of farms that utilize witch huts to obtain redstone dust.[1]

Gameplay[edit | edit source]

Effects
  • Improved player attribute and effect handling.
    • Custom set base attributes are now kept when respawning.
    • Active effects and modifiers are kept when changing dimension or winning the game.
Enchantments
  • Wind Burst
    • Invalidates the fall damage protection of mace smash attacks once again, reverting the fix of MC-270687.[2]

Sounds[edit | edit source]

Pistons
  • Changed sounds to lower their volume and attenuation.
    • This was done to address the old sounds being too harsh and loud when used in redstone contraptions.[1]

General[edit | edit source]

Credits
  • Have been updated.
Data pack
  • The version is now 44.
Custom structure
  • dimension_padding jigsaw structure tag was changed.
    • Now it is an object with fields:
      • bottom: the vertical padding at the bottom of the dimension, non-negative integer.
      • top: the vertical padding at the top of the dimension, non-negative integer.
    • Can be written as a single non-negative integer instead to be applied to both top and bottom fields.
      • e.g. both dimension_padding: 10 or dimension_padding: { bottom: 10, top: 5 } are valid.
  • Data-driven enchantment field weight now has an upper bound of 1024.
  • Data-driven enchantment field max_level now has an upper bound of 255.
  • New entity sub predicate movement_affected_by - optional location predicate.
    • When present, adds requirements on a block at most 0.5 blocks below the entity which can affect its movement.
