== Additions ==
=== Blocks ===
'''[[File:Pumpkin JE1 BE1.png|32px]] [[Minecraft:Pumpkin]]s'''
* New block, without the face.
* Previous pumpkin block has been renamed to "Carved Pumpkin".
** Right-clicking a pumpkin block with [[Minecraft:shears]] turns it into a carved pumpkin and makes it drop 4 [[Minecraft:pumpkin seeds]].

'''{{Animate|Oak Button (S) JE3.png; Spruce Button JE1 BE1.png; Birch Button JE1 BE1.png; Jungle Button JE1 BE1.png; Acacia Button JE1 BE1.png; Dark Oak Button JE1 BE1.png|32px}} {{Animate|Oak Pressure Plate JE3 BE1.png; Spruce Pressure Plate JE1 BE1.png; Birch Pressure Plate JE1 BE1.png; Jungle Pressure Plate JE1 BE1.png; Acacia Pressure Plate JE1 BE1.png; Dark Oak Pressure Plate JE1 BE1.png|32px}} {{Animate|Oak Trapdoor JE3.png; Spruce Trapdoor JE1 BE1.png; Birch Trapdoor JE1 BE1.png; Jungle Trapdoor JE1 BE1.png; Acacia Trapdoor JE1 BE1.png; Dark Oak Trapdoor JE1 BE1.png|32px}} [[Minecraft:Button]]s, [[Minecraft:pressure plate]]s, and [[Minecraft:trapdoor]]s'''
* Can now be made from all six types of wood.

=== Items ===
'''{{Animate|Oak Wood (UD) JE3.png; Spruce Wood (UD) JE3.png; Birch Wood (UD) JE3.png; Jungle Wood (UD) JE3.png; Acacia Wood (UD) JE4.png; Dark Oak Wood (UD) JE4.png|32px}} {{Animate|Red Mushroom Block (ESU) JE1 BE1.png; Brown Mushroom Block (ESU) JE1 BE1.png|32px}} [[File:Mushroom Stem (ESU) JE1 BE1.png|32px]] [[File:Petrified Oak Slab JE3.png|32px]] [[File:Smooth Quartz Block JE1 BE1.png|32px]] [[File:Smooth Red Sandstone JE1.png|32px]] [[File:Smooth Sandstone JE3.png|32px]] [[File:Smooth Stone JE1 BE1.png|32px]] [[Minecraft:Bark]], [[Minecraft:mushroom block]], [[Minecraft:mushroom stem]], [[Minecraft:petrified oak slab]], [[Minecraft:smooth quartz]], [[Minecraft:smooth red sandstone]], [[Minecraft:smooth sandstone]], and [[Minecraft:smooth stone]]'''
* Now have item forms in the creative inventory.

'''[[File:Debug Stick.gif|32px]] [[Minecraft:Debug stick]] '''
* Cycles between different block states.
** Left-clicking cycles through states; right-clicking cycles through values.
** Shift-clicking cycles through the states or values in reverse order.
** Only obtainable through commands

=== General ===
'''[[Minecraft:Options]]'''
* 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).

== Changes ==
=== Blocks ===
'''General'''
* [[Minecraft:Java Edition pre-flattening data values#Block IDs|Numeric block IDs]] no longer exist; there is no longer a limit to distinct possible block IDs.
* Blocks with a collision box now have matching bounding boxes.
** Affected: [[Minecraft:anvil]]s, [[Minecraft:brewing stand]]s, [[Minecraft:cauldron]]s, [[Minecraft:fence]]s, filled [[Minecraft:end portal frame]]s, [[Minecraft:glass pane]]s, [[Minecraft:hopper]]s, [[Minecraft:iron bars]], [[Minecraft:lily pad]]s, [[Minecraft:piston]]s, [[Minecraft:stairs]], and [[Minecraft:vines]]
** Updated the collision box of anvils and hoppers.
** Does not affect blocks with a collision box smaller than their [[Minecraft:model]], such as [[Minecraft:soul sand]] and [[Minecraft:snow]] layers.
* Blocks now emit the block breaking particles according to their size.
* The outline for block hitboxes can now have other shapes than just one cuboid. This causes the outline of stairs and other blocks to match with the hitbox.

'''[[Minecraft:Banner]]s'''
* Now make a sound when placed.

'''[[Minecraft:Bed]]s'''
* 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.

'''[[Minecraft:Button]]s'''
* Can no longer be placed on top of [[Minecraft:piston]]s.
* Renamed "Button" to "Stone Button".

'''[[Minecraft:Cacti]]'''
* Now break if [[Minecraft:sign]]s or [[Minecraft:banner]]s are placed directly next to it.
** Previously, these blocks couldn't be placed like this.

'''[[Minecraft:Chest]]s and [[Minecraft:trapped chest]]s'''
* 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 doesn't make the two chests or 2 trapped chests combine into a double chest or double trapped chest.

'''[[Minecraft:Cocoa bean]]s'''
* Can now be placed when aiming at blocks that it cannot be placed on if there is an adjacent block that they can be placed on.
* Can now replace replaceable blocks such as snow, fire or grass when placed by the player.

'''[[Minecraft:Dispenser]]s'''
* Crafting it no longer requires a fully repaired [[Minecraft:bow]].<ref name="damage">{{bug|MC-122844}} (resolved as "Works as Intended")</ref>

'''[[Minecraft:Door]]s'''
* Can now be placed by aiming at the side of a block.

'''[[Minecraft:Enchanting Table]]'''
* "Enchantment Table" has been renamed to "Enchanting Table".

'''[[Minecraft:Fence gate]]s and [[Minecraft:pumpkin]]s'''
* Placing them no longer requires a block below.

'''[[Minecraft:Head]]s'''
* Now make a sound when placed.
* Can no longer be placed inside entities.
* Player heads have been renamed from "Head" to "Player Head".

'''[[Minecraft:Infested block]]s'''
* Now break instantly, regardless of a tool that the player is using.
** When broken with [[Minecraft:Silk Touch]], the non-infested counterpart of the block drops.

'''[[Minecraft:Lever]]s'''
* Flicking it on now displays redstone [[Minecraft:particles]].
* Can no longer be placed on top of [[Minecraft:piston]]s.

'''[[Minecraft:Note block]]s'''
* Are no longer [[Minecraft:block entities]].
** Hence now pushable by pistons.

'''[[Minecraft:Redstone comparator]]'''
* Now has a bottom texture plane.

'''[[Minecraft:Redstone repeater]]'''
* Now has a bottom texture plane.

'''[[Minecraft:Redstone wire]]'''
* Now makes a sound when placed.

'''[[Minecraft:Sign]]s'''
* Now make a sound when placed.

'''[[Minecraft:TNT]]'''
* Removed the <code>explode</code> block state (explode on punch).<ref name="explode">{{bug|MC-122563}} (resolved as "Works as Intended")</ref>

'''[[Minecraft:Vines]]'''
* Multiple vines facing different directions, including on the bottom of blocks, can now be placed in the same block space.

=== Items ===
'''[[Minecraft:Carrot on a stick]]'''
* Now craftable with a damaged fishing rod.<ref name="craft">{{bug|MC-123196}} (resolved as "Works as Intended")</ref>

'''[[Minecraft:Spawn egg]]s'''
* Using them on blocks without collision box now spawns the mob inside that block rather than next to it.

=== World generation ===
'''[[Minecraft:Witch hut]]s'''
* Now generate with a [[Minecraft:mushroom]] in the [[Minecraft:flower pot]].
** Previously, they were completely empty.

=== Non-mob entities ===
''' [[Minecraft:Armor stand]]s'''
* Can now be placed inside water, lava and fire just like any other replaceable block.
* Can no longer step up blocks.

=== Command format ===
'''{{cmd|blockdata}}'''
* Removed in favor of {{cmd|data}}.

'''{{cmd|particle}}'''
* Particle names now use [[Minecraft:resource location]]s.
* Old ID → new ID:

'''{{cmd|playsound}}'''
* {{key|Tab}} auto-completes custom sound events.

=== Gameplay ===
'''[[Minecraft:Creative inventory]]'''
* Because of [[Minecraft:Java Edition 1.13/Flattening|The Flattening]], certain blocks and items have been moved around in their respective groups, for example, the [[Minecraft:purpur block]] is now after [[Minecraft:obsidian]].
* [[Minecraft:Mushroom block]]s, [[Minecraft:farmland]] and [[Minecraft:grass path]] are added to the inventory, under the ''Decoration Blocks'' group; blank [[Minecraft:firework rocket]]s are added to the ''Miscellaneous'' group; and bark, smooth stone, sandstone, red sandstone and quartz are added to the ''Building Blocks'' group.

=== General ===
'''[[Minecraft:Java Edition Flattening|The "flattening"]]'''
* Numeric block metadata completely phased out in favor of block states.
* Split, merged, created, deleted, and renamed a lot of [[Minecraft:block]]s, block states, block entities and [[Minecraft:item]]s.
** Blocks and items previously differing because of damage value have gotten their own ID, for example <code>white_wool</code> instead of <code>wool:0</code>
** Damage has been moved to the tag <code>tag</code> and is only used by tools, armor and maps.
** Files and commands no longer use <code>data</code> or <code>set_data</code>.

'''[[Minecraft:Statistics]]'''
* Are being updated.
** <code>stat.(stat)</code> is now <code>minecraft.custom:minecraft.(stat)</code>.
** <code>stat.(stat).minecraft.(block/item/entity ID)</code> is now <code>minecraft.(stat):minecraft.(block/item/entity ID)</code>.

'''[[Minecraft:Superflat]] customization'''
* Preset strings no longer use a version number.
