;[[Add-On]]s and Script Engine
*Added the ability to define the order for the items for the creative inventory and recipe book, called the crafting item catalog, for new items added by packs. New items can either merge with existing groups, create new groups with your own item for the icon, or just become added as loose items without a group. This catalog should be saved as {{cd|item_catalog/crafting_item_catalog.json}} in player's behavior pack.
*Item and Block json files now require a namespace for group names in the {{cd|menu_category}} object. 
*Added new Creator toggle setting "Show Content Log GUI On Error During Load".
**This setting with make the Content Log GUI automatically open and display after loading into a world and there was either warnings or errors found during the loading process.
**This setting is disabled in the [[Editor]].

;[[API]]
*Updated numeric JavaScript enums now properly handle and support reverse value mappings. 
*{{cd|InputPermissions}}
**Moved the following {{cd|InputPermissionCategory}} enum values to {{cd|1.17.0}}: {{cd|LateralMovement}}, {{cd|Sneak}}, {{cd|Jump}}, {{cd|Mount}}, {{cd|Dismount}}, {{cd|MoveForward}}, {{cd|MoveBackward}}, {{cd|MoveLeft}}, and {{cd|MoveRight}}.
**Moved the following methods on {{cd|PlayerInputPermissions}} to {{cd|1.17.0}}:
***{{cd|isPermissionCategoryEnabled(permissionCategory: InputPermissionCategory): boolean;}}
***{{cd|setPermissionCategory(permissionCategory: InputPermissionCategory, isEnabled: boolean): void;}}
*Removed the {{cd|compostingChance}} available from the {{cd|ItemStack}} API. The composting chance for Vanilla items can now be accessed via the singular {{cd|CompostableItemComponent-}}.

;[[Block]]s
*Removed "Upcoming Creator Feature" toggle requirement for {{cd|minecraft:item_visual}} component.
*Updated {{cd|minecraft:material_instances}} component
**Removed "Upcoming Creator Features" experiment requirement for {{cd|abmient_occlusion}} field to be {{cd|float}} type.
*Fence gate blocks use state {{cd|minecraft:cardinal_direction}} instead of {{cd|minecraft:direction}}. Uses string values ({{cd|north}}, {{cd|south}}, {{cd|east}}, {{cd|west}}).
*Door blocks use state {{cd|minecraft:cardinal_direction}} instead of {{cd|minecraft:direction}}. Uses string values ({{cd|north}}, {{cd|south}}, {{cd|east}}, {{cd|west}}).

;Collisions
*Entities with no collision box but with the {{cd|minecraft:custom_hit_test}} component are no longer sometimes unable to be interacted with.

;[[Command]]s
*The {{cd|mine}} overload of the {{cmd|loot}} command has been moved to outside of "Upcoming Creator Features" experiments.
*The {{cmd|kick}} command now allows use of target selectors on Realms.

;Components
*The [[strider]] now makes use of the {{cd|minecraft:movement_sound_distance_offset}} component for its movement sound distance offset.
*Added the {{cd|minecraft:renders_when_invisible}} component, which enables entities to render even when invisible.
**Appropriate rendering behavior can then be specified in the corresponding {{cd|minecraft:client_entity}}.
*Moved the {{cd|minecraft:liquid_detection}} component out of the Upcoming Creator Features experiment for {{cd|format_versions}} 1.21.60 and above.
*Expand the {{cd|minecraft:breedable}} component to allow inheriting properties to child entities.
**Adds the new {{cd|property_inheritance}} field which takes property name keyed objects.
**The objects in {{cd|property_inheritance}} can contain a {{cd|mutation_chance}} which give the chance it should not inherit from either parent.
**They can also contain the {{cd|mutation_values}} array of values to select from if mutating and the component has random mutation set.

;Entity Components
*The {{cd|minecraft:breedable}} component now has a field that enables the offspring's {{cd|minecraft:color}} attribute to be a blend of the parents' {{cd|minecraft:color}}.
**{{cd|combine_parent_colors}}, If a color mutation will not happen, the baby will get a combination of the parents' colors if the colors are compatible. Color combinations follow the rules of {{cd|DyeItem}} combinations. If the colors are not compatible the baby will get one of the parents colors chosen randomly.
***Valid values: {{cd|true}}, {{cd|false}}.

;Entity Filters
*Added new entity filter {{cd|home_distance}}, which checks the distance of an entity from its home.
**Requires the subject entity to have a {{cd|minecraft:home}} component.
**Returns {{cd|false}} if the subject has no home or if the home is in a different dimension.
*Added new entity filter {{cd|is_bound_to_creaking_heart}}, which checks if the creaking heart that spawned the subject creaking still exists.

;Graphical
*Improved logic for handling very large textures within atlases. Textures that are guaranteed to overflow the maximum atlas size will now have mips dropped individually rather than forcing the entire atlas to drop mips.
*Single-channel textures in resource packs are now interpreted as grayscale, rather than red. This change does not apply to single-channel UI textures, which were already interpreted as such.

;Graphics
*{{cd|client_biome}} JSON files now support a {{cd|surface_opacity}} field in the {{cd|minecraft:water_appearance}} component.
**This change also restores {{cd|swampland}} and {{cd|warm_ocean}} surface opacity to what they were until recently when the {{cd|client_biome}} JSON files were introduced.

;[[Item]]s
*Added a content warning to the {{cd|minecraft:durability_sensor}} item component's {{cd|particle_type}} when an invalid value is provided.
*The following legacy item (pre 1.16.100) components are now synced to the client:
**{{cd|minecraft:camera}}
**{{cd|minecraft:seed}}
**{{cd|minecraft:max_damage}}
**{{cd|minecraft:hand_equipped}}
**{{cd|minecraft:stacked_by_data}}
**{{cd|minecraft:foil}}
**{{cd|minecraft:block}}
**{{cd|minecraft:use_duration}}
**{{cd|minecraft:max_stack_size}}

;[[Sound]]s
*Added {{cd|base}} parameter to block sounds specifying another block sound they should use sounds for if they do not define a sound themselves.

;Network Protocol
*Added {{cd|ActorFlags::RENDERS_WHEN_INVISIBLE}}.
