Minecraft Snapshot 23w51b

Update: Coming in hot, here is Snapshot 23w51b, fixing a crash in 23w51a.

We're now releasing Snapshot 23w51a, the first snapshot for Minecraft 1.20.5. This one comes with a present for your pet Wolf in time for the holidays - and the Armadillo.

Happy brushing!

Bugs fixed in 23w51b

• Fixed a crash that would occur when the nametag of a player was visible during sleeping, swimming or dying

New Features

• Added Armadillo, Armadillo Scutes and Wolf Armor

Armadillo

• The Armadillo is a new passive mob that:
  • drops Armadillo Scutes periodically
  • drops Armadillo Scutes when brushed
  • spawns in Savannas
  • its favorite food is Spider Eye

Armadillo Rolling Up Behavior

• Armadillo rolls up when it detects a threat such as:
  • a sprinting player
  • a player in a vehicle or mounted
  • undead mobs
• It does not roll up when:
  • it is fleeing
  • in water
  • in the air or
  • on a leash
• When an Armadillo is rolled up it does not walk, cannot eat, and will not be tempted by food
  • It will continue to scan for threats: if none are detected for 3 seconds, it will unroll

Armadillo Scutes

• Armadillo Scutes can be used to craft Wolf Armor
• They are dropped by Armadillos
• Dispensers can be used to brush Armadillo Scutes off Armadillos

Wolf Armor

• Using Wolf Armor on an adult tamed Wolf will equip the armor on the wolf.
• Only a Wolf's owner can put a Wolf Armor on their tamed Wolf, and with this in mind; Dispensers cannot put Wolf Armor on wolves.
• Wolf Armor gives the same protection as Diamond Horse Armor.
• Using Shears on a Wolf that is wearing armor will make it drop the armor
• Only a Wolf's owner can shear a Wolf Armor from it, and with this in mind; Dispensers cannot remove Wolf Armor from wolves.
• If a Wolf dies while wearing armor, it will drop the armor.

Changes

• Renamed scutes that come from Turtles to Turtle Scutes
• Llamas and Shulkers are no longer able to destroy armor stands

Technical Changes

• The Data Pack version is now 27

Data Pack 27

• Llamas now use a new damage type spit instead of mob_projectile
• FactorCalculationData has been removed from mob effect instance tags
• Added generic.scale attribute that can be used to rescale any living entity
• Player reach distance can now be controlled with the generic.block_interaction_range and generic.entity_interaction_range attributes
• The maximum number of blocks that an entity can step up without jumping is now controlled by the generic.step_height attribute

Experimental Features

Breeze

• Added a new 'whirl' idle sound
• Added a 'charging up attack' sound
• Added a sound that plays while the Breeze is in the air
• Added a projectile deflection sound
• Tweaked existing sounds

Trial Spawner

• The Trial Spawner now has the same two default loot tables as they have in the Trial Chamber
