New

• Added biome and structure icons in the anchor screens, and block icons on requirement rows
• Biome and structure anchors can now share a chunk at different heights; each converts only its own vertical range
• Plains and Nether Wastes can now be built!
• /biomebuilder reload (ops) reloads both config files without a restart

Multiplayer

• The server now validates every anchor action (reach, permissions, anchor type, and tier/dimension of the target)

Fixes

• Desert, Soul Sand Valley, Bastion Remnant, Ocean Ruin, Pillager Outpost and Swamp Hut requirements now count the right blocks
• World lock didn’t work outside the development environment
• Deactivating an anchor after rebuilding it restored the wrong biome
• Structure anchors stayed lit after a nearby Biome Anchor turned them off “Elevation not met” wasn’t shown when rebuilding an active Structure Anchor
• Kelp, vines and big dripleaf now count every block of the plant, not just the top
• Some structure requirement labels weren’t shown (config typo) Requires Fabric Loader 0.15.11+ instead of 0.19.3

Notes

• World lock is now decided once, when a world is created. Changing it later doesn’t affect existing worlds, and worlds created before this update are never locked.
• Existing config files are updated automatically. Your edits are kept, and the old file is saved as .bak.
• Anchors that were active before updating still cover their whole chunk until you rebuild them.
