BCLib

Changes

• Config warnings about ignored entries show the full entry path
• Startup warnings about ignored config entries name the full entry path, so leftover switches in config files that are no longer read are easy to find
• Blocks and items can no longer be disabled in the config; old disabled entries are ignored with a warning instead of crashing the game (BetterEnd#281)
• Built for Fabric API 0.92.12+1.20.1 (Fabric Loader 0.19.5)

Fixes

• Slabs and stairs made from obsidian blocks keep their obsidian behaviour, so pistons can no longer push them
• The chair seat entity has a proper name instead of "entity.bclib.chair"
• Loading a singleplayer world no longer logs "Tried to read from global registry!" errors
• Sub-biomes and features are chosen the same way on every server start, so biomes and terrain no longer change at chunk borders after a restart
• World generation of BCLib-based mods no longer reads or writes blocks outside the area vanilla allows, which could crash or misplace blocks with C2ME
• The game no longer crashes when loading or creating a world with BetterNether and Colormatic, Vanadium or PCA (Carpet addon) installed (BetterNether#290, BetterNether#246, BetterNether#299)
• Mob spawners set with a BetterNether spawn egg spawned nothing when other entities were nearby (BetterNether#281)
• BetterEnd foods no longer share their food values with vanilla items, so mods that change food values per item (e.g. IguanaTweaks Reborn) only affect the intended item (BetterEnd#504)
• Signs of BetterEnd/BetterNether woods (e.g. Umbrella Tree signs in End houses) no longer crash the game when another mod loads the sign textures early (BetterEnd#308, BetterEnd#297)
• Players other than the one who placed a chair or bar stool are shown seated on it again instead of walking around while the server thinks they sit (BetterEnd#353)
• Unbreaking protects armored and crystalite elytras during flight as well as it protects the vanilla elytra (BetterEnd#321)
• Anvils from BCLib-based mods are part of the vanilla anvil block and item tags (BetterEnd#303)
• Voxel structures (giant ice stars, giant mossy glowshrooms) stored several megabytes per structure, too large to send to clients (BetterEnd#582)
• Eroded structure blocks no longer all slide in one direction with parallel worldgen (C2ME) (BetterEnd#477, BetterEnd#587)
• /bclib dump_datapack writes the "type" key into worldgen/betterx/biome files again, so the dump can be used as a datapack (BCLib#156)
• The game no longer crashes on startup when a custom block or item model can not be created; the model is skipped with a warning (BCLib#151, BCLib#211)
• Biomes listed in force_exclude of config/bclib/biomes.json no longer generate in the End and Nether, including vanilla and sub-biomes like End Highlands (BCLib#154)
• Existing worlds keep their End and Nether generator settings on restart, and dedicated servers only use server.json to pick the BetterX world preset (BCLib#160)
• Lithium no longer floods dedicated server consoles with "Class Analysis Error" for our blocks and items (BCLib#240)
• Dedicated servers no longer re-inspect every region file of the world on each start; unreadable chunks are skipped and the per-file log spam is gone (BCLib#146)
• Recipe lookups no longer sort every matching recipe on each call, which slowed down machines and furnaces (BCLib#225)
• BCLib no longer hooks every item check in the game for its shears support, which was blamed for server freezes (BCLib#233, BCLib#239)
• Players can join through a Velocity proxy again; /bclib no longer sends custom command argument types (BCLib#124)
• Placing a fully worn anvil no longer crashes, and dropped anvils keep their exact wear (BCLib#128, BetterEnd#289)
• EMI shows the anvil (hammer) recipes again, also on servers, and joining a server no longer logs "Tried to read from global registry!" (BCLib#193, BetterEnd#385)
• Axes mine wood fast again, and all tags BCLib ships load without "missing following references" errors (BCLib#234, BCLib#141, BCLib#145, BCLib#158, BCLib#171, BCLib#192, BCLib#206)
• Smithing with a hammer on an anvil no longer crashes dedicated servers (BCLib#127, BCLib#123, BCLib#164, BCLib#230)
• Dedicated server crashed on start because the update checker loaded a client-only class

Validation

• ✅ Dedicated server (Minecraft 1.20.1) started (BCLib 3.0.15, BetterNether 9.0.11, BetterEnd 4.0.12, wunderreich 6.0.5)
