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

• 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)
