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

This is the first release candidate of Lithium for Minecraft 1.18. It is missing many of the old optimizations which haven't been ported to 1.18 yet. Also parity with changes introduced in Minecraft 1.18 hasn't been well tested. Expect bugs and backup the world before testing this version.

This release adds fixes for several issues introduced in previous Lithium versions. Besides a serious chunk save format incompatibility with 1.18 snapshots, a memory leak and a mistake in the hopper logic are fixed. It is recommended that all users upgrade to this release.
Worlds that were used with Lithium will have chunk corruption when upgrading due to the breaking save format changes in the 1.18 snapshots. The datafixer responsible for upgrading to the new format is missing (MC-239610), which leads to chunk corruption and regeneration.
If you have used Lithium in the past and you want upgrade your world to Minecraft 1.18 snapshots, you need to follow these instructions for each world to avoid severe chunk corruption:
Instructions to avoid chunk corruption when updating to 1.18 snapshots:
If you are upgrading a world that has never been used with Lithium, or you are upgrading to a version that includes a fix for MC-239610, you are likely to be unaffected by this issue. If you are unsure, follow the instructions anyway.
- Singleplayer instructions: Start the game with Lithium 0.7.5 installed. Instead of opening your world, select it in the list of worlds, press "Edit", press "Optimize World", then "Create Backup and Load". Wait for the world to load, this will take a long time depending on the world size. After closing the world you can upgrade it to a newer Minecraft version.
- Server Instructions: Make a backup of the world. Start the game with the launch parameter
--forceUpgrade=true, e.g. by launching the server.jar withjava -jar server.jar --forceUpgrade=true. Wait for the world to load, this will take a long time depending on the world size. After closing the server you can upgrade it to a newer Minecraft version.
