* Added new item stack components.
* Added <code>food</code> item stack component.
** When present, this item behaves as if a food (can be eaten)
** Format: object with fields:
*** <code>nutrition</code>: non-negative integer, number of food points to restore when eaten.
*** <code>saturation_modifier</code>: float, amount of saturation to restore when eaten.
*** <code>can_always_eat</code>: boolean (default: <code>false</code>)

**** <code>probability</code>: float between 0 and 1, chance for the effect to be applied (default: <code>1</code>)
*** Example: <code>food={nutrition:4,saturation_modifier:0.1}</code>
** On food items, has an implicit default value for that food type.
* Added <code>max_stack_size</code>.
** Controls the maximum stacking size of this item.
** Format: integer between 1 and 99.
*** Example: <code>max_stack_size=4</code>
** Has an implicit default value according to the item type (usually <code>64</code> but can also be <code>16</code> and <code>1</code>)
* Added <code>max_damage</code>.
** Controls the maximum amount of damage than an item can take.
** If not present, the item cannot be damaged.
** Format: positive integer.
*** Example: <code>max_damage=123</code>

**** <code>correct_for_drops</code> (optional): boolean, overrides whether this tool is considered 'correct' if present and matched.
***** <code>true</code> causes the block to mine at its most efficient speed, and drop items if the targeted block requires that.
*** <code>default_mining_speed</code>: float, mining speed to use if no rules match and override mining speed (default: 1.0).
*** <code>damage_per_block</code>: non-negative int, amount of durability to remove each time a block is mined with this tool.

*** <code>storage</code>: namespaced id of command storage.
*** <code>path</code>: NBT path to field.

=== Gameplay ===
'''[[Minecraft:Advancement]]s'''
* Added a <code>crafter_recipe_crafted</code> trigger which is triggered when a [[Minecraft:crafter]] ejects a successfully crafted item into the world.
** <code><player></code> an entity predicate matching the player who is nearby.
** <code><recipe_id></code> is the ID of the recipe being crafted.
** <code><ingredients></code> is a list of item predicates matching the ingredients that form the recipe being crafted.

** <code><start_position></code> a location predicate matching the position the player was at when they were hit by the explosion or burst.
** <code><distance></code> a distance predicate matching how far the player must be from <code>start_position</code> to cause the trigger to activate.
** <code><cause></code> an entity predicate matching the entity which caused the explosion or burst to happen.

=== General ===

* Added <code>incorrect_for_wooden_tool</code>, <code>incorrect_for_gold_tool</code>, <code>incorrect_for_stone_tool</code>, <code>incorrect_for_iron_tool</code>, <code>incorrect_for_diamond_tool</code>, <code>incorrect_for_netherite_tool</code> block tags.
** These tags combine the existing <code>needs_diamond_tool</code>, <code>needs_iron_tool</code>, and <code>needs_stone_tool</code> tags for each specific tool tier.
* Added <code>meat</code> collection item tag.
** Contains {{cd|d=and|beef|chicken|cooked_beef|cooked_chicken|cooked_mutton|cooked_porkchop|cooked_rabbit|mutton|porkchop|rabbit|rotten_flesh}}

* Added <code>sensitive_to_smite</code> entity type tag.
** For entity types that take extra damage from the [[Minecraft:Smite]] enchantment.

== Changes ==
=== Command format ===
'''General'''
* Command arguments that previously accepted namespaced ids of loot tables, modifiers and predicates can now also accept inline definitions:
** <code>loot</code>
** <code>item</code>
** <code>execute if predicate</code>
** Values have same structure as matching JSON files, though they are encoded as SNBT. Example: <code>execute if predicate {condition:weather_check, raining:true}</code>

'''[[Minecraft:Entity sub-predicates]]'''
* <code>wolf</code>
** New <code>wolf</code> sub-predicate has been added to match wolf variantsFields: <code>variant</code> - wolf variant to match (single entry, list of entries or tag)
* <code>cat</code>, <code>frog</code>, <code>painting</code>
** Field <code>variant</code> now accepts single entries, list of entries or tags.
* <code>wolf</code>, <code>cat</code>, <code>frog</code> and <code>painting</code> entity sub-predicates now accept tags and plain lists instead of just single elements.

'''[[Minecraft:Loot functions]]'''
*<code>set_lore</code> function:
** The <code>replace</code> field has been removed.
** Now has <code>mode</code> like <code>set_fireworks</code> and <code>set_written_book_pages</code>.
* <code>set_written_book_pages</code> function:
** <code>pages</code> is now a JSON object rather than a string containing JSON.
* Nested lists are no longer supported in function lists.

'''[[Minecraft:Item predicate argument]]'''
* The item predicate syntax (used in <code>execute if|unless items</code> and <code>clear</code> commands) has been significantly expanded.
* The general syntax is: <code><type> [comma-separated list of <test>]</code>
* <code><type></code> can be one of:
** item id
** item tag id prefixed with <code>#</code>
** <code>*</code> to match any item.
* <code><test></code> can have one of 3 forms:
** <code><component_id>=<value></code> - match exact value of component (same as in previous format)
*** <code><value></code> is a representation of component value in SNBT format (same as in <code>item give</code> argument)
** <code><component_id></code> - check if component exists.
** <code><predicate_id>~<value></code> - check item sub-predicate.
*** <code><value></code> is a representation of item sub-predicate in SNBT format (but otherwise same as one used for advancement and loot table JSON files)
*** Example: <code>*[damage~{durability:{min:3}}]</code> matches any stack with at least 3 uses left.
* The special name <code>minecraft:count</code> can be used for matching the stack size.
** <code>count=<positive int></code> passes only when the stack size equals the given value.
** <code>count~<int range></code> passes when the stack size is in the specified range.
*** Example: <code>*[count~{max:2}]</code> matches any stack with count <= 2.
** <code>count</code> always passes.
* Any <code><test></code> entry can be negated by prefixing with <code>!</code>
** Example: <code>*[!count=1]</code> matches any stack that has count other than 1.
* <code><test></code> elements can be also joined with | to check multiple alternatives.
** Example: <code>*[!damage|damage=0]</code> looks for items without damage component or with 0 damage.
* Removed redundant custom data section (<code>{...}</code>) from item arguments (it's fully replaced by <code>[custom_data={...}]</code>)
** To make this transition easier, <code>custom_data</code> item sub-predicate has been changed to allow unquoted SNBT.
* The syntax for custom data partial matching (<code>{}</code>) has been removed in favor of using <code>custom_data</code> predicates.
** So <code>stick{a:2}</code> becomes <code>stick[custom_data~{a:2}]</code>

'''[[Minecraft:Item sub-predicates]]'''
* Predicate <code>minecraft:custom_data</code> now accepts both SNBT data written as a string (existing format) and unflattened tags.
** That means that <code>*[custom_data~{a:1}]</code> and <code>*[custom_data~"{a:1}"]</code> are equivalent.
** Flattened string format has been kept since NBT type information can't be expressed in JSON.

=== General ===
'''[[Minecraft:Data pack]]s'''
* The data pack version is now <code>36</code>.

'''[[Minecraft:Resource pack]]s'''
* The resource pack version is now <code>30</code>.
* Changed texture asset paths in <code>wolf_variant</code> to better match other formats.
** Field <code>texture</code> has been renamed to <code>wild_texture</code>
** <code>wild_texture</code>, <code>tame_texture</code> and <code>angry_texture</code> no longer require values to be prefixed with <code>textures/</code> and suffixed with <code>.png</code>.
* Particle <code>entity_effect</code> takes color argument when spawned from command <code>/particle entity_effect {{cd|r}} {{cd|g}} {{cd|b}} {{cd|a}}</code>.
** 4 float values ranging from 0.0 to 1.0 representing RGBA.
* Removed <code>map_icons.png</code>{{more info}}
** Map decoration icons have been split from the former <code>map_icons.png</code> to use an atlas loaded from the <code>textures/map/decorations/</code> directory.
** The atlas is now generated upon loading resources: [[Minecraft:map_decorations.png-atlas]]
* The process of upgrading a pack can be assisted by using an automated Slicer tool.<ref>https://github.com/Mojang/slicer/releases/tag/v1.1.4</ref>
* Added <code>trial_chambers</code> map decoration icon.

'''[[Minecraft:Tag]]s'''
* <code>axolotl_tempt_items</code> has been renamed to <code>axolotl_food</code>.
