This is an unofficial maintenance fork of Thaumic JEI, originally created by Buuz135.
Original project: https://modrinth.com/mod/thaumic-jei
This fork keeps the original Thaumcraft recipe browsing features, including Arcane Workbench, Crucible, Infusion, aspect compound recipes, aspect source lookup, and research-aware recipe display.
Differences from the original project:
Improves aspect source cache behavior so cached data can be reused and refreshed incrementally instead of being rebuilt every startup by default. Adds cache migration support for the original aspect cache format. Improves research sync behavior for hiding and showing recipes based on player research progress.
Adds additional logging to make recipe registration, cache syncing, and research syncing easier to diagnose.
