Changes[edit | edit source]

Items[edit | edit source]

Wolf armor

Changed the crack textures.

Mobs[edit | edit source]

Bees and parrots

Adjusted their flying behavior to keep them from overshooting their position when flying up and down.

Wolf

When summoned using spawn eggs or commands, the variant selection now follows the natural spawning biome rules with the following extensions:
- Rusty wolf is selected in jungles and bamboo jungles.
- Spotted wolf is selected in savannas and windswept savannas.
- Striped wolf is selected in badlands and eroded badlands.

Command format[edit | edit source]

Predicates

Removed any entity sub-predicate.
Added slot name contents for single-slot entities like item frames and item displays.
Contents of item entity can now be accessed through contents slot name.
Component-specific item predicate properties have been moved to separate field predicates.
- Some fields from item predicate have been moved to a map in an optional field predicates.
- The new field is similar to the components field on item stacks.
- This was done to simplify addition for future predicates and to allow sub-predicates to more closely resemble names of components they match.
- The following fields have been moved:
  - enchantments - field moved to sub-predicate minecraft:enchantments
  - stored_enchantments - field moved to sub-predicate minecraft:stored_enchantments
  - potions - field moved to sub-predicate minecraft:potion_contents
  - custom_data - field moved to sub-predicate minecraft:custom_data
durability field has been expanded to minecraft:damage predicate:
- This check now works for any item that has minecraft:damage component
- An item that does not have a minecraft:damage component can never match
- To check for unbreakable items, query value of minecraft:unbreakable component
- Fields:
  - damage - optional bounds for value of minecraft:damage component
  - durability - optional bounds for durability (max damage minus value of minecraft:damage)
Predicates minecraft:enchantments, minecraft:stored_enchantments, minecraft:potion_contents and minecraft:damage require matching component to exist on item
- That means that, for example, matching for empty enchantment list doesn't pass on items without minecraft:damage component
- Note: some components, like minecraft:enchantments have default values, so they always match

General[edit | edit source]

Background

Menu background blur has been updated to look better and improve performance.

Experimental[edit | edit source]

Additions[edit | edit source]

Blocks[edit | edit source]

Heavy core

A mysterious, dense block which can be combined with a breeze rod to craft a mace.
Can be found as a loot reward in vaults with a chance of 2.2%.
When placed, it has the same size as a player head, and can be oriented in 12 directions.
Mining a heavy core is pretty slow - it takes 45 seconds to mine and has no correct tool.
Are fully resistant to explosions.
Pop off immediately if pushed by a piston.

Items[edit | edit source]

Banner patterns

Added two new banner patterns:
- Flow banner pattern
- Guster banner pattern

Breeze rod

Dropped by the breeze.
Can be crafted into 4 wind charges.
Can be used with the heavy core to craft a mace.

Mace

A new heavy weapon that can be crafted from a breeze rod and a heavy core.
Using the weapon while falling can increase the damage output. The higher the player falls, the more damage is dealt.
- This can be done by jumping towards the target and hitting them before the player hits the ground.
- Successfully striking a target in this way negates any damage accumulated from the fall, similar to how a wind charge works.
- Other entities near the struck enemy receive knockback.
Can not be enchanted.
Can be repaired with breeze rods using an anvil.
Can be used to mine cobwebs, dropping string.
Players can use a mace in combination with wind charges to launch up and deliver devastating smash attacks on their enemies.

Pottery sherds

Added 3 new pottery sherds, that can be found on decorated pots inside of trial chambers:

Smithing templates

Added two new smithing templates, that are exclusively obtained from vaults:
- Bolt armor trim
- Flow armor trim

Changes[edit | edit source]

Blocks[edit | edit source]

Trial spawners

Now appear more frequently in the trial chambers corridors.

Vaults

Their loot tables have been updated to address some inventory management issues.
- The player now gets no more than 1 unstackable item per vault.
- The player more often gets rewards which can stack together.
- Horse armor and saddles have been removed from the loot table.
Can now eject:

Mobs[edit | edit source]

Breeze

Drops 1-2 breeze rods instead of wind charges when killed by a player.
- The number of breeze rods dropped is affected by Looting.

World generation[edit | edit source]

Trial chambers

Added new chambers and variations, with new challenges.

- Remade chamber_9, and renamed it to slanted.
- Remade chamber_3, and renamed it to pedestal.
Added flow, guster, and scrape pottery sherds to the decorated pots in the decor structure pool.
Changed the layout of the blocks around vaults.
