17w47a is the sixth snapshot released for 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.

Additions

Blocks

• Trapdoors, buttons and pressure plates made from all six types of wood.
• A pumpkin block, without the face. The previous pumpkin block has been renamed "Carved Pumpkin".
  • Right-clicking a pumpkin block with shears will turn it into a carved pumpkin and make it drop 4 pumpkin seeds.
• Multiple vines facing different directions, including on the bottom of blocks, can now be placed in the same block space.

Items

• An item form for bark blocks for all six types of wood.
• An item form for petrified oak slab - the old wood slab that acts like a stone slab.
• An item form for smooth quartz, smooth red sandstone, smooth sandstone, and smooth stone.
• An item form for red and brown mushroom blocks and mushroom stems.
• A debug stick to cycle 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.

General

• Options 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).

Changes

Blocks

• The upper limit of the block ID has disappeared.
• Blocks which used to have no bottom texture (like repeaters, comparators, torches, etc.) now have a bottom texture, not including redstone wire.
• Flicking a lever on now displays redstone particles.
• Blocks with a collision box now have matching bounding boxes.
  • Affected: anvils, cauldrons, hoppers, fences, iron bars, glass panes, filled ender portal frames, vines, lily pads, stairs, brewing stands, and pistons
  • Updated the collision box of anvils and hoppers.
  • Does not affect blocks with a collision box smaller than their model, such as soul sand and snow layers.
• Beds 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.
• Chests and trapped chests can 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.
• Placing pumpkins and fence gates no longer requires a block below them.
• Silverfish-infested blocks will 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.
• Blocks now emit the block breaking particles according to their size.
• Buttons and levers can no longer be placed on top of pistons.
• Crafting a Dispenser no longer requires a fully repaired bow.
• Removed the TNT explode block state (explode on punch).

General

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

• 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).

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.

Superflat customization

• Preset strings no longer use a version number.
