Highlights

1.21.7 beta

I've marked 1.21.4 and 1.21.5 as stable since they aren't buggy, but they are still missing a few mods. 1.21.7 may possibly be buggy. No release was made for 1.21.6 as the changes between 1.21.6 and 1.21.7 are pretty minimal.

Missing mods in 1.21.4

  • EBE
  • CLL/SLC
  • CIT Resewn

Missing mods in 1.21.5

  • EBE
  • CLL/SLC
  • ModernFix

Missing mods in 1.21.7 beta

  • ModernFix
  • Noisium
  • CIT Resewn

Capes Provider

Capes has been replaced with Capes Provider on 1.21.4, 1.21.5, and 1.21.7. It offers some extra features that Capes doesn't have.

Highlights

mc1.21.4 beta

mc1.21.4 beta is missing Enhanced Block Entities (mod is updated but has bugs) and leaf culling. Also missing Animatica, CIT Resewn, and FabricSkyboxes+Interop. Other than that, it should be pretty stable.

Missing mods
  • Enhanced Block Entities
  • Sodium Leaf Culling
  • CIT Resewn
  • Animatica
  • Fabric Skyboxes + Interop

Updated mods

Most of the mods in the modpack have been updated. Fabric loader has been updated.

Simulation distance 5->8

Improves vanilla parity with mob spawning. This should not matter if you play on servers. If you play in single player and need the most performance, you can change it back.
