Changes

Blocks

Minecraft:Ender chest

• Now pick the closest Minecraft:structure more accurately, regardless of structure type.

Minecraft:Glow squid

• Now require complete darkness to spawn.

Minecraft:Tropical fish

• Now only spawn if the block above is a full Minecraft:water block.

World generation

Minecraft:Bastion remnant

• Bounding boxes are now slightly more accurate to the shape of the structure.

Minecraft:Custom world generation

• Some fields in worldgen structures that previously only lists of element IDs now accept tags.
  • Those entries now accept [id, ...], id (shortcut for [id]), and #tag.
  • Changed fields are:
    • feature.glow_lichen configuration: can_be_placed_on
    • feature.spring_feature configuration: valid_blocks
    • feature.simple_random_selector configuration: features
    • block_predicate_type.matching_blocks: blocks
    • block_predicate_type.matching_fluids: fluids
    • biome: inner list in features, map value in carvers
    • biome_source.checkerboard: biomes
• Some tag fields now require id to be prepended with #, however they are not yet accepting element list:
  • dimension_type: infiniburn
  • feature.geode configuration: blocks.cannot_replace, blocks.invalid_blocks
  • feature.vegetation_patch, feature.waterlogged_vegetation_patch configuration: replaceable
  • feature.root_system configuration: root_replaceable
  • structure_processor.protected_blocks: value
• Structure fields in noise settings no longer have separate subfields for strongholds and non-stronghold structures. Instead each structure has a tag field which is tag: concentric_rings for strongholds and tag: random_spread for non-stronghold structures.

Seed

• A seed of the number zero is no longer handled as a special case.
• Any spaces before/after an inputted seed are trimmed.

Minecraft:Superflat

• "Redstone Ready" preset's top layer of blocks has increased to height Y=55 instead of Y=-9 in order to prevent Minecraft:slimes from spawning.
• Changed the "Water World" preset, by replacing Minecraft:sand with Minecraft:gravel, and adding additional 64 layers of Minecraft:deepslate above the Minecraft:bedrock layer, in order to fix the Minecraft:ocean monument generation issue in worlds using this preset.

Command format

Template:Cmd

• Now uses a namespaced ID parameter.
• Now support Minecraft:tags, using Template:Cd prefix to distinguish from normal IDs.
• The parameter is now a configured structure rather than a structure type.
