WorldWeaver

Features

• Startup parameter -Dwover.suppressScreens=true hides the welcome, update and experimental-world screens for automated clients
• wover-test-api: StructureTemplateAudit checks a mod's shipped structure templates
• StructureNBT.readTemplate and getTemplate: the single structure template loader
• Build for Minecraft 26.3

Changes

• WorldWeaver refuses to start next to Polymer 0.18.3, whose virtual entities (e.g. Universal Graves) crash the server once a mod adds Nether biomes through Fabric API
• WorldWeaver logs only at info level by default
• Deprecated ClientBlockTraits.MODEL, attach a BlockModelBinding (ModelKey + client factory) instead
• Deprecated the ClientBlockTraits render aliases, use BlockRenderTraits and ItemRenderTraits
• Modded compostables use the minecraft:compostable component

Fixes

• Vanilla Nether biomes almost never generated next to biomes of other mods (e.g. Biomes O' Plenty)
• Servers crashed when Polymer-based mods (e.g. Universal Graves) created virtual entities
• Food built with RecipeBuilder.cookableFood could not be cooked in a furnace
• The world preset info registry was not loaded when TerraBlender was installed, so new worlds stored the wrong overworld preset
• End structure pieces (BetterEnd villages) decided whether they are buried by reading blocks two chunks away, which logged unsafe terrain reads and could cut pieces off
• The fabric tool tags (axes, hoes, pickaxes, shears, shovels, swords, spears) had no translation
• The warning for level-type=minecraft:normal claimed modded Nether/End biomes would not generate; they do, only the WorldWeaver biome layout is missing (WorldWeaver#29)
• Turkish system locale broke loading of BetterNether/BetterEnd worldgen data (BetterNetherWorldWeaver#285)
• BiomeBuilder colors no longer use the client-only ColorHelper, which crashed a dedicated server
• StructureNBT did not upgrade older structure templates, so they loaded as air on 26.3
• Spears exposed a tool rule without a tag key, crashing mods that inspect tool rules, and lost their spear attack speed (BetterEnd#601)
• Tool sets were missing the tags vanilla lists its tools in by item (#minecraft:cluster_max_harvestables, #c:tools/mining_tool, #c:tools/melee_weapon) (BetterNether#197)
• Bookshelves didn't count as #minecraft:enchantment_power_provider, and the magic-source check ignored #enchantment_power_transmitter (BetterNether#216)
• Silk-touch loot tables with several drop pools dropped the block once per pool (BetterNether#226)
• Structures placed oxidized copper, amethyst and netherite debug blocks (BetterNether#316, BetterNether#231)
• Worlds affected by the bed-foot home POI bug kept the stale entries, so villagers stayed stuck (BCLib#231)
• Biomes with genChance 0 crashed the biome source instead of being disabled (BCLib#216)
• Game crashed on startup with an ExceptionInInitializerError when installed alongside Nyf's Quivers (WorldWeaver#19)
• Dedicated servers silently created a vanilla Nether and End when server.properties set level-type=minecraft:normal; they now warn and explain how to pick the BetterX preset (WorldWeaver#29)
• Surface rules that other mods add to the End through TerraBlender (e.g. Biomes O' Plenty) were ignored (WorldWeaver#25)
• Several WorldWeaver tags had no translation, so Fabric reported untranslated item tags (WorldWeaver#28)
• The welcome screen reappeared on every start when it was closed with Escape instead of Proceed (WorldWeaver#31)
• Servers crashed with "Tags not bound" when another mod registered a flammable block tag before WorldWeaver blocks (WorldWeaver#37)
• Building from a fresh clone failed without a maven publishing token (WorldWeaver#16)
• WorldWeaver was not marked as a library in Mod Menu (WorldWeaver#23)
• Tools from an EquipmentSet rendered flat instead of handheld
• Biome modifications can insert features before existing ones
