Minecraft Snapshot 25w34b

August 20, 2025

This week brings a refreshing update, featuring a new main menu panorama, a comprehensive Code of Conduct for servers, and continued enhancements alongside our new companions, the Copper Golems. As the mining adventures unfold, players can look forward to a more structured gaming experience.

Developer’s Note: The rendering changes introduced in version 25w31a for entities have now been extended to encompass block entities and items. Please report any issues you encounter in these areas.

In the latest update, Snapshot 25w34b has been released, addressing some connectivity errors with Realms, ensuring a smoother experience for players.

Fixed bugs in 25w34b

MC-300911 – Glowing items and blocks will no longer display a glow.

New Features

Servers can now implement an in-game Code of Conduct.

Server Code of Conduct

Upon connecting to a server, players will now encounter a Code of Conduct screen:

Acceptance of the Code of Conduct is mandatory to access the server.
A checkbox allows players to opt out of seeing the same Code of Conduct in the future:
- If the Code of Conduct is updated, it will be displayed again.

Server Setup

A new boolean field has been introduced in server.properties, named enable-code-of-conduct:
- Setting this to true prompts the server to search for code of conduct files in the codeofconduct subfolder, located alongside server.properties.
- Each file should follow the format <languagecode>.txt</languagecode>:
 - The language displayed will attempt to match the player’s language.
 - If a match isn’t found, the en_us code of conduct will be used.
 - If that also doesn’t exist, an arbitrary available entry will be utilized.

Changes

The main menu has been refreshed with an updated background panorama featuring Copper Golems in a village setting.

The End Light Flashes

The sound effect produced by a flash now has an increased delay.
The “Hide Lightning Flashes” accessibility setting has been renamed to “Hide Sky Flashes,” which now also disables the End Flashes:
- When the flash is disabled via this setting, the world will not be illuminated by the flash, though the source of the flash will still be visible in the sky, and the sound effect will continue to play.

Minor Tweaks to Blocks, Items, and Entities

The eyes of the Copper Golem will now also be invisible when splashed with a Potion of Invisibility.
The hitbox of the Copper Golem has been adjusted:
- The width is now 0.6 blocks, allowing it to navigate through open doors.
- The height has been set to 1.01 blocks to prevent it from getting stuck in certain blocks.

Sounds

The Copper Golem and Copper Chests can now be heard from up to 12 blocks away.
The sounds associated with copper sorting have been modified to be quieter.

Technical Changes

The Data Pack version has been updated to 84.0.
The Resource Pack version has been updated to 66.0.

Data Pack Version 84.0

Player profiles in data components and block entities will no longer resolve automatically.
A new fetchprofile command has been introduced for downloading player profiles.

Block States

The alignitemsto_bottom block state property has been removed from the Shelf block:
- This has been replaced with a similarly named boolean field on the Shelf block entity.
- Shelves created with this property in the last snapshot will revert to the default value (false).

Commands

Added fetchprofile

This new command allows users to fetch the contents of a player profile from Minecraft servers.
Due to the potential time required for this operation, it functions asynchronously:
- Results will be displayed only upon completion, while the game continues to run unpaused.
Upon successful completion, a message will allow users to copy the contents of a fully resolved minecraft:profile component or /give @s minecraft:player_head with said component.
As the result is unknown at the time of execution, this command will always return 1.

Syntax:

fetchprofile name – resolves profile by name (case-insensitive).
fetchprofile id – resolves profile by id.

Data Components

Modified minecraft:profile

Previously, the contents of this component would change permanently when the profile was resolved, i.e., downloaded from the Minecraft service.
To prevent issues with this unexpected change, the resolved value will no longer be stored, and the contents of the profile will remain unchanged.
This component now exhibits two behaviors:
- Static: when it contains a properties field, or when both name and id are present, or when both are absent:
 - In this state, the profile will always render as-is.
 - If the properties field is missing, a default skin will be used (selected based on id, similar to offline mode).
 - This means the skin will be frozen at the moment of component creation, making it preferable for decorative uses.
- Dynamic: when it contains either name or id (but not both):
 - When an item containing this profile is rendered on the client side, the profile will resolve to the most recent value.
 - This means that the item will always display the current skin of the targeted player:
 - Note: if a player changes their skin while the game is running, the change will not be visible until clients restart.
 - Resolution may occur with a delay, during which the item will display a default skin.
 - The profile name will replace the item name only when present:
 - Items with only id will show a default name.
 - Items with dynamic profiles will be distinguished from static ones with a label in the tooltip.
- Items stack based on exact contents, so even if a dynamic component eventually resolves to the same profile as a static one, they will not stack together.
- Player heads in older maps that have not been loaded in newer versions will typically convert to dynamic contents.

Block Entity Data

Modified minecraft:skull

The profile field has been updated to align with the minecraft:profile component:
- This means it also becomes immutable and is resolved only when necessary.

Text components

Bold and italic styles are disregarded when rendering sprites.

Resource Pack Version 66.0

The block state alignitemsto_bottom has been removed from the Shelf block:
- Refer to the above details for further information.
