Lithium

This is the first experimental release for Lithium 0.14.0 which supports both the fabric and neoforge modloader. Make sure to take a backup of your world before using this experimental version. In case you find any bugs, please report them at the issue tracker. You can check the description of each optimization and how to disable it when encountering a problem.

Changes

• Adapt almost all optimizations and settings to work with neoforge

Lithium 0.13.1 fixes one bug and a compatibility issue with carpet mod.

Fixes

• fix: incompatability with fabric-carpet's scarpet explosion event. (#565) (Thanks to wendavid552)
• fix: disable broken mixin.world.game_events.dispatch optimization by default

Lithium 0.13.0 is the first release for 1.21.1. It fixes an issue and adds two new optimizations for goats and frogs.

Additions

• new: LongJumpTask random weighted choice optimization
• new: nonvanilla FrogAttackablesSensor optimization (enable with mixin.minimal_nonvanilla=true in the lithium.properties file. The frog target selection will deviate slightly from vanilla behavior.)

Fixes and Changes

• fix: Hoppers not transferring to ChiseledBookshelfBlockEntity when multiple books are in a stack
• change: replace hashmap in brain collection optimization
• change: enable explosion exposure optimizations by default

Lithium 0.12.5 is a bugfix release, fixing a critical hopper minecart issue affecting comparators.

What's Changed

• fix: Item stack resurrection causing incorrect internal state of LithiumStackList

Lithium 0.12.7 fixes a few issues like sculk sensors not working after a chunk reload, too few chickens spawning from thrown eggs, fluids flowing towards the wrong hole and hopper minecarts making inventories have incorrect signal strengths. In case you find any bugs, please report them at the issue tracker. You can check https://github.com/CaffeineMC/lithium-fabric/blob/mc1.21-0.12.7/lithium-mixin-config.md for a description of each optimization and how to disable it.

What's changed

• fix: fluid flow using incorrect direction in bfs
  • Affected all fluid flowing (#526)
• fix: Item stack resurrection causing incorrect internal state of LithiumStackList
  • Affected comparators after hopper minecarts performed a failed item extraction attempt from the inventory (#524)
• fix: empty space search incorrectly returning space as fully occupied when completely empty
  • Affected thrown eggs, entity pose calculations and entity positioning inside nether portals (#525)
• fix: chunk reload causing game event dispatchers to not be registered
  • Affected all types of game event listeners (e.g. sculk sensors and catalysts, wardens, allays) (#522)

Lithium 0.12.5 is the first release for 1.21. It includes several new optimizations. For now, some new optimizations are disabled by default, because mod compatibility issues still need to be resolved. Check https://github.com/CaffeineMC/lithium-fabric/blob/mc1.21-0.12.5/lithium-mixin-config.md for a description of each optimization and how to disable them if any issues arise.

Additions

• new: optimized explosion entity exposure (thanks to RacoonDog)
• new: general raycast optimization
• new: empty space search optimization for entity positioning when using nether portal
• new: disable useless nearest item sensor in goats
• new: skip sprinting particle creation logic used by all mobs on server side
• new: fluid flow (nearest hole search) optimization
• new: skip ticking mob equipment when there aren't any tickable enchantments (only soul speed)
• new: avoid creating and dispatching game events (vibrations) to sections without any listeners
• new: skip accessing chunks when trying to dispatch game events

Changes

• change: vanilla's supporting block used for additional entity movement fast- path
• change: track mob equipment using the item stack listening system to optimize checking whether updates must be sent
• change: enable block entity supporting block caching by default

Bugfixes

• fix: wolf armor not updating visually
• fix: use correct entity box for world border collision check
• fix: neighbor path node types initialized to OPEN, allowing mobs to pathfind directly next to dangerous blocks

Lithium 0.12.4 is a bugfix release, fixing a critical pathfinding issue.

What's Changed

• fix: wolf armor not updating visually
• fix: use correct entity box for world border collision check
• fix: neighbor path node types initialized to OPEN, allowing mobs to pathfind directly next to dangerous blocks

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
