General

Minecraft:Recipe book

• Recipe book icon now is a separate file, it's stored in the recipe_button.png.
• Added a recipe book for the furnace.
  • Furnace recipes have been moved to JSON files.
    • They use "type": "smelting".
    • cookingtime is used to determine the time it should take to smelt an item in the furnace.
    • experience is used to determine the amount of experience a player should get when picking the resulting item out of the furnace manually.
    • Fuel is not included and is still hardcoded.
• "Unlocked recipe" toasts now show an icon in the top left to specify whether the unlocked recipe is a crafting or smelting recipe.

  • minecraft:banners, minecraft:wooden_pressure_plates, minecraft:wooden_slabs, and minecraft:wooden_stairs.
• Added new vanilla item tags:
  • minecraft:banners, minecraft:boats, minecraft:wooden_pressure_plates, minecraft:wooden_slabs, and minecraft:wooden_stairs.

Changes

Items

Minecraft:Crops

• Wheat, carrots, potatoes, beetroots, melons, and pumpkins now can grow at night. Previously, they needed at least an Minecraft:internal light level of 9, but this was changed so that they needed only a sky or block light of the same level.

World generation

General

• Rewrote the world generation system.
• Structures previously grouped under "Temple" have their spawning locations changed, this allowed Template:Cmd to differentiate between the structures.
• In Minecraft:the Nether, vertical air cavities — stretching from bedrock level to as far as Y=35, and filled with Minecraft:lava from bedrock level to Y=10 – now occur in chains across the bottom of the Nether, often forming extensive ravines.

Customized world type

• Removed as a result of the world generation changes.

Minecraft:Trees

• Large Minecraft:spruce trees now transform nearby Minecraft:grass blocks into Minecraft:podzol when they grow.
• Trees occasionally generated upside down.<ref>Template:Bug</ref>

Command format

General

• Whitespaces are now allowed in entity selectors & blockstate arguments.

Template:Cmd

• Now accepts different structure names for all structures previously grouped under temple.
  • desert_pyramid, igloo, jungle_pyramid, and swamp_hut.

Trivia

• Unlike most of the first-of-the-week snapshots, this was released on a Friday instead of Wednesday.
