About this project

What does OPAC-UI add?

Dependencies

opac-ui always requires Open Parties and Claims - it's a client-side add-on, not a standalone mod. Exact versions per branch:

Branch Minecraft Loader(s) Open Parties and Claims Cloth Config API Fabric API Forge Config API Port
1.20.1/main 1.20.1 Fabric ≥ 1.20.1 ≥ 11.x 0.92.11+1.20.1 Fabric only
1.21.1/main 1.21.1 Fabric, Forge, NeoForge ≥ 1.21.1 ≥ 15.x 0.105.0+1.21.1 (Fabric) Fabric and Forge (not needed on NeoForge)
26.1.2/main 26.1.2 Fabric, Forge, NeoForge ≥ 26.1.2 not used 0.145.4+26.1.2 (Fabric) Fabric and Forge (not needed on NeoForge)
26.2/main 26.2 Fabric, Forge, NeoForge ≥ 26.2 not used 0.159.0+26.2 (Fabric) Fabric and Forge (not needed on NeoForge)

Notes:

  • Cloth Config was dropped starting with the 26.1.2/main branch since it no longer ships a Forge build - the party screen there is built entirely with Minecraft's own UI components instead.
  • 26.1.2/main also needs Java 25 (bundled with the game; only relevant when building from source).

Check the README and CHANGELOG on each branch on Github for further loader-specific notes.
