Additions

Mobs

Wolf

Added variants of wolves.
- The familiar pale wolf now spawns in taigas.
- The rusty wolf spawns in sparse jungles.
- The spotted wolf spawns in savanna plateaus.
- The black wolf spawns in old growth pine taiga.
- The striped wolf spawns in wooded badlands.
- The snowy wolf spawns in groves.
- The ashen wolf spawns in snowy taigas.
- The woods wolf spawns in forests.
- The chestnut wolf spawns in old growth spruce taiga.^[2]
- Wolves spawned with a spawn egg spawn as the variant associated with the biome the egg is used in. They default to pale wolf in any other biome.

General

Entity predicate

Added entity sub-predicate slots, used to check single or multiple slots on any entity.
- For slot ranges, only one slot needs to match for whole entry to pass.
- The field contains a map of slot names (same as ones used in item commands) to item predicate.
- Example:

{
    "condition": "minecraft:entity_properties",
    "entity": "this",
    "predicate": {
        "slots": {
            "container.*": {
                "items": "dirt"
            }
        }
    }
}

Inventory

Added new slot names:
- container.*: contains container.0 to container.53.
- hotbar.*: contains hotbar.0 to hotbar.8.
- inventory.*: contains inventory.0 to inventory.26.
- enderchest.*: contains enderchest.0 to enderchest.26.
- villager.*: contains villager.0 to villager.7.
- horse.*: contains horse.0 to horse.14.
- weapon.*: contains weapon.mainhand and weapon.offhand.
- armor.*: contains armor.head, armor.chest, armor.legs, armor.feed, and armor.body.
- player.cursor: item held by player on screen except Creative mode^[3].
- player.crafting.0, player.crafting.1, player.crafting.2, player.crafting.3, and player.crafting.*: player's crafting slots.

Changes

Blocks

Grindstone

No longer accepts items with [NBT Compound / JSON Object] unbreakable component that do not have an enchantment.
- If the item above has durability, it can be repaired with an unbreakable item and the output doesn't inherit [NBT Compound / JSON Object] unbreakable component. If the order is swapped, the item is neither repaired nor disenchanted. If the only item in the slots is an enchanted unbreakable item, it is disenchanted and [NBT Compound / JSON Object] unbreakable component remains.
No longer disenchants two enchanted books at the same time.

Player head

Now stores item name in custom_name tag.
Tags SkullOwner and ExtraType are replaced with profile to keep a consistent format with the item component form.

Items

General

Now count is stored again when there is only 1 item.
- Defaults to 1 if this field is invalid.

Mobs

Wolf

Now spawns on coarse dirt and podzol blocks.
Now spawns in sparse jungle, savanna plateau, and wooded badlands biomes.

World generation

Grove

Rabbits, wolves, and foxes are now the only passive mobs spawning in the grove biome.

Command formats

/execute

if and unless sub-commands can now use items to compare or count items.
- execute if|unless items <source> <slots> <item_predicate>
  - <source> is the same one as used in /item.
    - e.g. block <x> <y> <z> or entity <target> (selector can return multiple entities)
  - <slots> can accept single slot (like container.0) or a range (like container.*)
  - <item_predicate> is the same as item predicate in /clear command.
If used alone, it returns total number of items in stacks that match predicates.

General

Data packs

The data pack version is now 34.
Banner patterns are now be loaded into the registry from data/<namespace>/banner_pattern/<id>

[NBT Compound / JSON Object]: The root object.
- [String] asset_id: A namespaced id for the texture. e.g. custom:pattern resolves to assets/custom/textures/entity/banner/pattern.png and assets/custom/textures/entity/shield/pattern.png.
- [String] translation_key: A translation key prefix. e.g. block.minecraft.banner.custom.pattern resolves to block.minecraft.banner.custom.pattern.<color>.

Item stack components

[String][NBT Compound / JSON Object] profile no longer requires [String] name field.
Some additional item stack components now support alternative, simple definitions:
- [NBT Compound / JSON Object] profile can now be defined as [String] profile for a player name. e.g. profile="jeb_".
- [NBT Compound / JSON Object] dyed_color can now be defined as [Int] dyed_color. e.g. dyed_color=16711680.
- [NBT Compound / JSON Object] attribute_modifiers can now be defined as [NBT List / JSON Array] attribute_modifiers. e.g. attribute_modifiers=[{type:'generic.scale',uuid:[1,2,3,4],name:'Big!',amount:1.0,operation:'add_multiplied_base'}].
- [NBT Compound / JSON Object] potion_contents can now be defined as a single potion id [String] potion_contents. e.g. potion_contents="invisibility".
- [NBT Compound / JSON Object] enchantments and [NBT Compound / JSON Object] stored_enchantments can be defined as an inline map of enchantment id to level: enchantments={sharpness:1}.
- When stored, they still are in full formats.
[NBT Compound / JSON Object] container now applies to all containers instead of only shulker boxes.
[NBT Compound / JSON Object] lodestone_target is renamed to [NBT Compound / JSON Object] lodestone_tracker.
- [Int Array] pos and [String] dimension are now moved to [NBT Compound / JSON Object] target (optional).
- When [NBT Compound / JSON Object] target does not exist, the compass spins.
[NBT List / JSON Array] lore and [NBT List / JSON Array] fireworks/explosions now allows 256 entities.
Items with [NBT Compound / JSON Object] can_break and [NBT Compound / JSON Object] can_place_on can now be stacked properly.

Recipe

Can now specify item component.
- [NBT Compound / JSON Object] result field for crafting_shaped, crafting_shapeless, stonecutting, and smithing_transform now accepts [NBT Compound / JSON Object] components.
- [String] result field for smelting, blasting, smoking, and campfire_cooking recipes are now an item stack without count. That is, [String] id must be specified and [NBT Compound / JSON Object] components is now accepted.

Tags

Added coarse_dirt and podzol to #wolves_spawnable_on.

Tooltip

No longer appears when hovering outside the containing element.
