Minecraft Snapshot 24w20a

After some recent irregularities in our Snapshot schedule (public holidays, we're looking at you!) we're back to shipping on a Wednesday! Among other things, 24w20a includes a buff to the amount of Redstone Dust dropped by Witches, as well as a long requested change to make Piston sounds a tad more pleasing to the ear. We're also throwing 41 new bug fixes into the mix, because we like squashing bugs.

Happy mining!

Changes

• Witches now always drop 4-8 redstone dust on death
  • This is to improve the viability of farms that utilize Witch Huts to obtain Redstone Dust
• 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
• Updated credits

Sounds

• Updated Piston sounds to lower volume and attenuation
  • This was done to address the long-received feedback on the old sounds being too harsh and loud, creating very noisy redstone builds

Technical Changes

• Data Pack version is now 44

Data Pack Version 44

• dimension_padding jigsaw structure NBT 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

Predicates

Entity Predicate

• New option: 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
