This release is a backport for 1.19.2.

Lithium 0.11.0 fixes a tiny difference in the collision code that was noticeable in some tnt duper designs. Furthermore a few bug fixes and mod compatibility improvements are included. Besides all of that, Lithium now uses a new system internally for the available configuration options. Now you can check out a description of all optimizations here.

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

Lithium 0.10.3 is the first release for 1.19.3. Changes from 0.10.2:

Additions

• new: world.combined_heightmap_update: update the four heightmaps together when placing/breaking blocks

Fixes

• fix: block.hopper: hoppers not reacting when placing/breaking inventories without block updates
• fix: block.hopper: hopper not notified about inventory changes anymore after placing comparator next to output inventory of hopper
• 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

• change: simplify locked hopper sleeping mixin
• change: block.hopper: replace effective overwrite redirect with inject

Fixes

• fix: block.hopper: set mixin priority to be before fabric-transfer-api-v1
• fix: hopper sleeping causing fabric api item transfer to be skipped
• fix: use set instead of list to avoid duplicated entries and memory leak with sleeping hoppers

Lithium 0.9.1 fixes a critical issue with hoppers that stopped reacting to entities after being lazy loaded.

Fixes

fix: sleeping hoppers that become lazy loaded aren't woken up from entity movements (Thanks to QPCrummer)

Lithium 0.9.0 is a large update that includes new block entity optimizations and fixes several issues. The block entity optimizations improve the performance of hoppers, shulker boxes, campfires, furnaces and brewing stands by skipping their tick when they can't do anything. Futhermore several small behavior changes were fixed and mod compatibility was improved.

Additions

• new: hopper, shulker box, campfire, furnace and brewingstand sleeping
• new: aggressive hopper sleeping with comparator, entity movement and inventory change tracking
• new: avoid sending comparator updates when there is no comparator nearby
• new: optimized hopper minecart item entity search
• new: system for hopper sleeping
• new: block entity ticker caches whether it is inside the world border
• new: use fastutil hashmap as blockentity ticker collection

Changes

• change: avoid implementing LithiumInventory in LockableContainerBlockEntityMixin (mod compatibility)
• change: stationary storage minecarts on rails no longer notify hoppers in every tick
• change: chest boats inside stationary minecarts do not trigger the movement tracking system all the time
• change: replace suffocation overwrite with inject (mod compatibility)

Fixes

• fix: math.sine_lut: slightly off sin() and cos() results
• fix: unpushable_cramming: crash when entity ids are not unique (related to Hypixel/Wynncraft server)
• fix: entity.skip_equipment_change_check: mob crossbow changes not sent to clients
• fix: entity.fast_powder_snow_check: use landing instead of stepping block state
• fix: block.hopper: run loot generation on chest boats when converting to lithium stack list
