DeepNull Reforged 4.1.3-alpha-fabric-26

First alpha for Fabric on Minecraft 26.1.

This is the first alpha build of the 26.1 Fabric branch. Core gameplay systems are ported and the current automated checks are green, but this is still an early release and you should expect rough edges while the port continues to be refined.

Highlights

• DeepNull Reforged is now available on Fabric 26.1
• DeepNull and DampNull tiers, upgrades, docking, and Null Workbench functionality have been brought forward to the new version
• JEI integration and carried crafting transfer are working on the 26.1 Fabric build
• DeepNull and DampNull client rendering, interaction flow, and screen behavior have been updated for the 26.1 client
• Fluid handling, storage sync, and docking behavior have been ported to the new Fabric environment
• This release passed regression tests, GameTests, dedicated-server smoke checks, and client startup smoke checks during release validation

Notes

• This build should be treated as an alpha, not a final stable release
• Back up worlds before updating
• Requires Minecraft 26.1, Fabric Loader 0.18.5 or newer, and Java 25
• Mekanism-related chemical features remain optional and only appear when the required compat is installed
• If you are moving from an older Fabric build, test important storage and automation setups in a backup world first
