17w47a[1] is the sixth snapshot released for Java Edition 1.13, which added a new type of pumpkin, debug sticks, an item form of many blocks which previously could only be placed using commands, tweaked the placement conditions for many blocks, performed The Flattening, and much more.



Buttons, pressure plates, and trapdoors
  • Now made from all six types of wood.
  • New block, without the face.
  • Previous pumpkin block has been renamed to "Carved Pumpkin".
    • Right-clicking a pumpkin block with shears will turn it into a carved pumpkin and makes it drop 4 pumpkin seeds.


Bark, mushroom blocks, mushroom stems, petrified oak slabs, smooth quartz, smooth red sandstone, smooth sandstone, and smooth stone
  • Now have an item form.
Debug stick
  • Cycles between different block states.
    • Left-clicking cycles through states; right-clicking cycles through values.
    • Shift-clicking will cycle through the states or values in reverse order.


  • New option when editing a world to make a backup and open the backups folder.
  • An option in chat settings to toggle automatic command suggestions (defaults on, otherwise hit tab to bring them up).



  • Now require a block below it as a support.
    • Previously, this was only required when placing the bed and the block could be destroyed afterward without the bed being destroyed.
  • Can no longer be placed on top of pistons.
  • Now break if signs or banners are placed directly next to it.
    • Previously, these blocks couldn't be placed like this.
Chests and trapped chests
  • Can now be put directly next to their double variants instead of requiring one block between them.
    • Shift right-clicking a chest or trapped chest next to a chest or trapped chest respectively will not make the two chests or 2 trapped chests combine into a double chest or double trapped chest.
  • Crafting it no longer requires a fully repaired bow.[2]
Fence gates and pumpkins
Note blocks
Silverfish-infested blocks
  • Now break instantly, regardless of a tool that the player is using.
    • When broken with Silk Touch, the non-infested counterpart of the block will drop.
  • Removed the explode block state (explode on punch).[3]
  • Multiple vines facing different directions, including on the bottom of blocks, can now be placed in the same block space.


Carrot on a stick
  • It's now possible to craft a carrot on a stick with a damaged fishing rod.[2]

World generation[]

Witch huts

Creative inventory
  • Because of The Flattening, certain blocks and items have been moved around in their respective groups, for example, the purpur block is now after obsidian.
  • Mushroom Blocks, farmland and grass path are added to the inventory, under the Decoration Blocks group; blank firework rockets are added to the Miscellaneous group; and bark, smooth stone, sandstone, red sandstone and quartz are added to the Building Blocks group.


The "flattening"
  • Numeric block metadata completely phased out in favor of block states.
  • Split, merged, created, deleted, and renamed a lot of blocks, block states, block entities and items.
    • Blocks and items previously differing because of damage value have gotten their own id, for example white_wool instead of wool:0
    • Damage has been moved to the tag tag and is only used by tools, armor and maps.
    • Files and commands no longer use data or set_data.
  • Statistics are being updated.
    • stat.(stat) is now minecraft.custom:minecraft.(stat).
    • stat.(stat).minecraft.(block/item/entity ID) is now minecraft.(stat):minecraft.(block/item/entity ID).
Superflat customization
  • Preset strings no longer use a version number.
