4.263.0.0-rc.2

Second release candidate for Minecraft 26.3, available for Fabric and NeoForge.

Changed

• Replaced Cloth Config with EasyConfig for the client and server settings screens.
• Client preferences are accessible from Fabric's Mod Menu and NeoForge's mod-list config button.
• Settings screens edit a temporary draft. Save applies valid changes; Done closes without saving, Reload reads the latest client file or synchronized server settings, and Reset restores defaults in the draft. Invalid input blocks saving.
• Client and server settings now use EasyConfig-generated TOML files.
• Server edits retain operator permission checks and validation; item-weight datapacks continue to use JSON.

Installation and upgrading

• Requires Minecraft 26.3 and Java 25, with matching Heavy Inventories builds on clients and servers.
• Install EasyConfig 1.263.0.9 or newer for your loader. Fabric also requires Fabric API. EasyConfig is required on both clients and dedicated servers, including NeoForge.
• Heavy Inventories no longer requires Cloth Config. Keep it installed if another mod needs it.
