Lithium

Lithium 0.12.3 is the first release for 1.20.6. The new minimal_nonvanilla package is introduced, which is meant for optimizations which technically are different from vanilla in an observable way, but do not affect any gameplay or any contraptions. If any negative effect on your contraptions or gameplay is noticeable, please report this to our issue tracker, as this would be considered to be a bug. Check https://github.com/CaffeineMC/lithium-fabric/blob/mc1.20.6-0.12.3/lithium-mixin-config.md for a detailed description of what each package does, and how to disable certain optimizations if needed.

What's Changed

• Replace axis.choose() with switch in VoxelShapeAlignedCuboid
• Move mixin.experimental.chunk_tickets package to minimal_nonvanilla.world.expiring_chunk_tickets
• Move mixin.world.chunk_tickets package to mixin.collections.chunk_tickets

Lithium 0.12.2 is the first release for 1.20.5.

What's Changed

• Mod compatibility improvements contributed by embeddedt, ishland and Steveplays28
• Added missing lithium$ prefixes to mixin methods
• Slight improvements and 1.20.5 adaptation for existing optimizations

Lithium 0.10.4 fixes a critical issue that causes heightmaps to store wrong values when placing or breaking blocks. It might have affect beacons, mob spawning and more. After fixing the bug the wrong values will still be in the world save. If you notice wrong heightmap behavior in some locations, placing and breaking a normal block (e.g. stone) above the location will update the heightmap to the correct value.

Fixes

• fix: combined_heightmap_update always using y & 15 as height causing incorrect heightmap

• fix: world.tick_scheduler: chunk tick scheduler peek returning wrong scheduled tick in some cases leading to wrong ticking order
• fix: world.tick_scheduler: chunk tick scheduler broken after loading a structure block
