Minecraft Java Edition - 26.3 Snapshot 1 – Minecraft Feedback

Word around the campfire is the new forest biome is out in testing! But if nobody's been to the dappled forest before, who built the abandoned camp? And what loot did they leave among the poplar trees and red shrubs? Scout out the place and set up shelter using the new wood set and other features from our next game drop. The expedition into wilderness starts now in testing!

Happy mining!

Minor Tweaks to Blocks, Items and Entities

Sherds dropped from breaking a Decorated Pot will now preserve data, for example custom name

Technical Changes

The Data Pack version is now 108.0
The Resource Pack version is now 89.0
Some log lines that server software might look out for have been removed
- The Minecraft Server Management Protocol can be used instead
- If you are missing access to specific events, please create a feature request on the Feedback site

Minecraft Server Management Protocol 3.1.0

Added notifications indicating when the server performs a full world upgrade on startup
- minecraft:notification/world/upgrade_started
- minecraft:notification/world/upgrade_progress
- minecraft:notification/world/upgrade_finished
- minecraft:notification/world/upgrade_failed

Data Pack Version 108.0

Commands like /give, /unpublish, and /tick should now properly signal errors
Pottery sherds are now data-driven
Entries stored in minecraft:pot_decorations component and minecraft:decorated_pot block entity are now full item stacks

Commands

Changes to give

When the amount of items passed to the give command is above limit, the command will now signal an error instead of just printing an error message and returning 0

Changes to tellraw

The nbt component in a raw chat message will only be resolved up to 64k times

Changes to tick

The following subcommands will now signal an error instead of just printing an error message and returning 0:
- tick step
- tick step stop
- tick sprint stop

Changes to team

The result of team join and team leave subcommands now reflects the exact count of entities that have joined or left (i.e. excluding entities for which teams have not changed)

Changes to item

Now takes a slot source as argument in place of anywhere a slot was previously used
- It will be evaluated with the minecraft:command_slot_source loot type
- Can be a slot source in either inline or reference form
- Can be a slot source targeting multiple slots
- The replace sub-command has new semantics:
  - One by one in the order they are provided by the slot source, the contents of each destination slot are replaced with the corresponding source item
  - When there are more destination slots than there are source items, the remaining slots are ignored
    - Example: replace [12345] with (ABC) -> [ABC45]
  - When there are fewer destination slots than there are source items, the remaining items are ignored
    - Example: replace [123] with (ABCDE) -> [ABC]
- String notation slot ranges in the form <slot_type> or <slot_type>.<slot_number> are still permitted
  - Can be a single slot, such as armor.chest
  - Can be multiple slots, such as container.*
  - Acts as shorthand for a minecraft:slot_range slot source using that slot range
    - Example: hotbar.4 is the same as {type:"minecraft:slot_range",slots:"hotbar.4"}
The entity argument in the from entity item source can now be a selector targeting multiple entities
- When more than a single entity is targeted, the slots sourced from each are concatenated
Added new fill and override sub-commands, each with syntax identical to /item replace
- /item fill
  - Fills each destination slot with a source item
  - When there are more destination slots than there are source items, the items repeat until every slot is filled
    - Example: fill [12345] with (ABC) -> [ABCAB]
- /item override
  - Overrides the contents of each destination slot with the corresponding source item
  - When there are more destination slots than there are source items, the remaining slots are cleared
    - Example: override [12345] with (ABC) -> [ABC__] (where _ represents an empty slot)

Changes to execute

Added new slots condition sub-command
- Counts the number of slots from the slot source that are present on the targeted block or entity
- The slot source will be evaluated with the minecraft:command_slot_source loot type
- Syntax:
  - /execute if|unless slots block <pos> <slot source>
  - /execute if|unless slots entity <targets> <slot source>
The items condition sub-command now takes a slot source as argument instead of a slot
- The slot source will be evaluated with the minecraft:command_slot_source loot type
- Syntax:
  - /execute if|unless items block <pos> <slot source> <item predicate>
  - /execute if|unless items entity <targets> <slot source> <item predicate>

Data Components

Added minecraft:provides_pottery_pattern

Describes the pottery pattern stored on a stack
Format:
- namespaced ID pointing to an element of minecraft:decorated_pot_pattern registry

Added durability_damage field - optional non-negative integer, amount of durability to consume on each use
Updated use_duration field - can now be 0 for no cooldown

Block Entity Data

minecraft:decorated_pot

Field sherds no longer stores a list of 4 item IDs. Instead, the new format is an object with 4 optional item stack fields named:

front

Slot Sources

Slot sources can now be defined as files inside a Data Pack, within the slot_source folder
- Can be used in commands which take slot sources as arguments
- Can be used in inline slot sources using the minecraft:reference type
minecraft:contents is no longer restricted to only selecting non-empty slots

Added minecraft:reference

Uses the referenced slot source
Fields:
- name - the namespaced id of the slot source

Changed minecraft:slot_range

The source field has a new valid type container, which sources slots from a container or inventory provided through loot context

Noise Settings

The surface_rule field has been renamed to material_rule
- Format: inline Material Rule or Material Rule ID reference

Material Rule Registry

A new data-driven registry has been introduced, loaded from data/<namespace>/worldgen/material_rule/<id>.json.

Elements in this registry define a pipeline for selecting what base block to place in the world at a given position.

The format is identical to that which was formerly written in the surface_rule field within Noise Settings files, with the following extensions:

Material Rules can now be specified either inline (as previously), or as an ID reference to an element in the worldgen/material_rule registry
Material Conditions can also now be specified as an ID reference to an element in the worldgen/material_condition registry

Material Condition Registry

A new data-driven registry has been introduced, loaded from data/<namespace>/worldgen/material_condition/<id>.json.

Elements in this registry define a condition that can be referenced within a Material Rule pipeline (e.g. testing biome or surface depth).

Palette Textures

All armor trim palette textures have been moved from textures/trim/color_palettes/ to textures/palettes/trim/
- The base armor trim palette texture has instead been moved to textures/palettes/trim_base.png
Entity armor trim material textures are no longer generated into the minecraft:trims atlas with paletted_permutations, but rather generated on-demand
