Additions

Blocks

• 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.

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.

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 tagtag 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.
