Minecraft Loader Fundamentum Notes
26.1.2 NeoForge 1.25.6 the main line: everything on this wiki; works under Iris shader packs
1.21.1 NeoForge 21.1 1.25.6 everything except a few parts that need newer Minecraft (below)
26.2 NeoForge 26.2 1.25.2 the same as 26.1.2 at 1.25.2 (no Shift tooltips or Jade line yet)
26.3 NeoForge 26.3 1.25.2 the same as 26.2
1.20.1 Forge 47 1.25.2 the same as 1.21.1 at 1.25.2, with the same parts left out

What 1.21.1 leaves out

  • Wings drawn from an equipment asset's wings layer (wings still work as a slot item; mods draw their own).
  • Item model faces with light_emission: glowing faces use neoforge_data light in the model instead.
  • Whip item model conditions are ItemProperties overrides instead of item model definitions.
  • The on_shelf display context.
  • A recipe book category for portal crafting (JEI still shows the recipes).
  • Mounts saddle through Saddleable; mobs that only exist on 26.x (the happy ghast, the nautilus) aren't there.
