BCLib

Features

• Block items can show hand-written tooltip lines (DescriptionBlockTrait, as on 26.x)

Changes

• Saplings of BetterX mods take bone meal like vanilla saplings (45% per use, about 4-5 per tree instead of ~32); natural growth is unchanged
• JEI anvil recipes show how many items one craft consumes, with the usable hammers and anvils, in one Anvil Smithing category
• World patches that do not apply are only listed in the log with WorldWeaver's verbose logging
• Block model traits are bound through WorldWeaver model keys instead of client-only lambdas
• org.betterx.ui.ColorUtil is deprecated, use ColorUtilARGB32 (or ClientColorUtil for texture colors)
• Removed StructureNBT, StructureWorldNBT and StructureHelper; use WorldWeaver's StructureNBT
• SaplingBlockTrait.ticking(): the sapling behaviour without the bundle
• Composting rates snap to a fixed set of tiers

Fixes

• The "Survives on" tooltip of plants with several soil rules lists each block once, in one sorted list
• Recipes disabled in a datapack's bclib/config/recipes.json could still be crafted
• Colors read from item textures (e.g. infusion particles) had red and blue swapped
• SDF fills read blocks outside their write bounds
• StructureErode.erode let dislodged blocks vanish instead of falling, could move or duplicate a block more than once and shifted the remaining columns after a move
• StructureWorld pieces left block entities behind when they replaced a block
• StructureErode.erodeIntense read outside its box, which logged unsafe terrain reads for BetterEnd crashed ships
• Worn anvils stored their wear ambiguously, so some dropped anvils came back one stage more or less worn (BCLib#128)
• /bclib place empty and /bclib place nbt crashed with the 'at' placement (BCLib#124)
• The world patcher logged a warning for every rewritten chunk; it now reports the number of rewritten chunks and files in its summary line (BCLib#195)
• Structure placement types failed to load on servers with a Turkish system locale (BetterNetherBCLib#285)
• Dedicated servers no longer crash at startup on BCLib's client-only references
• A new world on a dedicated server no longer logs "Failed fixing Level-Data"
• Voxel structures (giant ice stars, giant mossy glowshrooms) stored several megabytes per structure, too large to send to clients (BetterEnd#582)
• Hide custom fog options that no longer have any effect (BetterNether#175, BetterNether#131, BCLib#244)
• Receiving a BCLib data-exchange packet would close the Minecraft client
• Custom command argument types broke Velocity proxies (BCLib#124)
• World patch inspection logged one unprefixed line per region file (BCLib#195)
• DataFixer re-inspected the whole world on every server start when a region held an unreadable chunk (BCLib#146)
• Feature seeds changed with neighbouring biomes, causing chunk seams (BCLib#227)
• Recipe lookups sorted every matching recipe on each call (BCLib#225)
• Shears loot check could misfire when loot ran on several threads (BCLib#233, BCLib#239)
• Placing a fully worn leveled anvil crashed (BCLib#128)
• BCLib could not be hidden as a library in Mod Menu (BCLib#229)
• SpawnRuleBuilder.maxNearby counted every entity instead of only the given type (BetterNether#281)
• World fixer aborted on backpacks holding a non-string "id"
• Patches supplying only a chunk or block-state patcher never ran
• Stalactite tip did not re-render as pointy after mining the block beyond it
• Compostable items could not be composted by a hopper
