Minecraft Snapshot 25w35a

August 27, 2025

This week’s update introduces an innovative Minecraft Server Management Protocol, enhancing server capabilities by allowing real-time queries of player activity, adjustments to game rules, and updates to server settings. Notably, several server properties have been transitioned into game rules, enabling modifications while the server is operational. Players can now express themselves more creatively in chat with the addition of player icons, while the copper golem has received various enhancements, alongside a collection of bug fixes aimed at improving overall gameplay experience.

New Features

Support for the Halychian language has been added, broadening the game’s accessibility.

Changes

Recipes

Hanging Signs can now exclusively be crafted using Iron Chains, streamlining the crafting process.

UI

The server list now requires a manual entry for new server names, reverting to a default name if left blank.
Enhanced text input functionality allows users to select text via mouse dragging in more areas.

Mouse Cursor

UI components will now alter the mouse cursor’s shape for better user interaction, including:

Text inputs
Numeric sliders
Buttons
Scroll bars

Clickable text labels will display a hand-shaped cursor, enhancing usability. This feature can be disabled in the “Mouse Settings…” menu.

Minor Tweaks to Blocks, Items, and Entities

The hitbox of Copper Golems has been adjusted to 0.98 blocks in height, improving their pathfinding capabilities in one-block-high spaces.
Copper Chests spawned by Copper Golems now correctly connect to adjacent Copper Chests.
The Copper Golem’s functionality has been refined, allowing it to utilize the Saddle equipment slot for blocks placed on its Lightning Rod, while its Head equipment slot now operates like a standard head slot.

Technical Changes

The Data Pack version has been updated to 85.0.
The Resource Pack version is now at 67.0.
The new Minecraft Server Management Protocol has been introduced.

Server Properties

In a move to streamline server management, several properties have been removed in favor of game rules, allowing for dynamic changes during gameplay:

Removed server property allow-nether in favor of a new game rule.
Removed server property spawn-monsters in favor of a new game rule.
Removed server property enable-command-block in favor of a new game rule.
Removed server property pvp in favor of a new game rule.

Introduced server property management-server-port, defaulting to 25585.
Introduced server property management-server-host, defaulting to localhost.
Introduced server property status-heartbeat-interval, defaulting to 0, meaning it’s disabled.

Minecraft Server Management Protocol

The newly added server management API (JSON-RPC over WebSocket) is designed for dedicated servers:

By default, the API is disabled but can be activated in the server properties file.
Accessible at ws://: when enabled.
Supports querying and updating server state, including players, allowlist, operators, settings, and game rules.
Notifies users of state changes, such as player joins and game rule updates.
Complies with JSON-RPC 2.0 specifications, featuring namespaced methods for extensibility.
