General

Entity Minecraft: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:

<syntaxhighlight lang="json">{

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

}</syntaxhighlight>

Minecraft: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 Template:Cd.
- player.cursor: item held by player on screen except Minecraft:Creative mode<ref>Template:Bug</ref>.
- Template:Cd: player's crafting slots.

Changes

Blocks

Minecraft:Grindstone

No longer accepts items with Template:Nbt component that do not have an enchantment.
- If the item above has Minecraft:durability, it can be repaired with an unbreakable item and the output doesn't inherit Template:Nbt 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 Template:Nbt component remains.
No longer disenchants two Minecraft:enchanted books at the same time.

Minecraft: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

Minecraft:Wolf

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

World generation

Minecraft:Grove

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

Command formats

Template:Cmd

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 Template:Cmd.
    - 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 Template:Cmd command.
If used alone, it returns total number of items in stacks that match predicates.

General

Minecraft:Data packs

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

Template:Nbt: The root object.
- Template:Nbt: 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.
- Template:Nbt: A translation key prefix. e.g. block.minecraft.banner.custom.pattern resolves to block.minecraft.banner.custom.pattern.<color>.

Minecraft:Item stack components

Template:Nbt Template:Nbt no longer requires Template:Nbt field.
Some additional item stack components now support alternative, simple definitions:

- Template:Nbt can now be defined as Template:Nbt. e.g. dyed_color=16711680.
- Template:Nbt can now be defined as Template:Nbt. e.g. attribute_modifiers=[{type:'generic.scale',uuid:[1,2,3,4],name:'Big!',amount:1.0,operation:'add_multiplied_base'}].
- Template:Nbt can now be defined as a single potion id Template:Nbt. e.g. potion_contents="invisibility".
- Template:Nbt and Template:Nbt can be defined as an inline map of Minecraft:enchantment id to level: enchantments={sharpness:1}.
- When stored, they still are in full formats.
Template:Nbt now applies to all Minecraft:containers instead of only Minecraft:shulker boxes.
Template:Nbt is renamed to Template:Nbt.
- Template:Nbt and Template:Nbt are now moved to Template:Nbt (optional).
- When Template:Nbt does not exist, the compass spins.
Template:Nbt and Template:Nbt now allows 256 entities.

Minecraft:Recipe

Can now specify item component.
