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 | v15.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) |
Notes:
- Cloth Config was dropped starting with the
26.1.2/mainbranch 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/mainalso 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.
