'''1.13''', the release of the '''[[Minecraft:Update Aquatic]]''',<ref>{{Mcnet|update-aquatic-out-java|Update Aquatic Out On Java!|July 18, 2018|Adrian Östergård}}</ref> is a major update to {{JE}} released on July 18, 2018. It focused mainly on ocean content and technical features.<ref name="customcrafting">{{tweet|Dinnerbone|856505341479145472|It'll probably be in 1.13 at this point, I'm afraid :( It'll be a more bugfixy and technical update, so it will get more love then.|April 24, 2017}}</ref><ref>{{tweet|Dinnerbone|919870475249078272|Remember that 1.13 is a technical update to make things crash less, run faster, & easier for us to add/change stuff later. Like new blocks!|October 16, 2017}}</ref> Specifically, new blocks, such as [[Minecraft:blue ice]], [[Minecraft:coral]], [[Minecraft:conduit]]s, [[Minecraft:kelp]], [[Minecraft:sea pickle]]s, [[Minecraft:stripped log]]s, [[Minecraft:wood]], and [[Minecraft:turtle egg]]s were added, as well as new items such as buried treasure [[Minecraft:explorer map]]s, [[Minecraft:debug stick]]s, [[Minecraft:buckets of fish]], [[Minecraft:hearts of the sea]], [[Minecraft:phantom membrane]]s, [[Minecraft:trident]]s, and much more. Also, [[Minecraft:water]] is more transparent than before and the color was changed to match specific biomes, while it was only dark blue before 1.13. In addition, [[Minecraft:dolphin]]s, [[Minecraft:drowned]], [[Minecraft:fish mob]]s, [[Minecraft:phantom]]s, and [[Minecraft:turtle]]s were added, as well as new biomes, a new [[Minecraft:buffet]] world type (a stopgap replacement for the [[Minecraft:Old Customized|customized]] world type), and new generated structures. This update also added many commands and changed the format of existing commands, and added many new technical aspects, such as [[Minecraft:data pack]]s and [[Minecraft:tag]]s. Due to the update's vast technical changes such as world generation, the update severely degraded the performance of {{JE}}.

This update was originally intended to be released as two separate updates with 1.13, originally named ''Technically Updated'', having the technical changes, and 1.14, originally to be called the ''Update Aquatic'', having all the ocean features, however they were combined into one big update,<ref name=merge/> and as such snapshots from [[Minecraft:17w43a]] to [[Minecraft:18w06a]] mainly just added or modified commands.

The update was originally revealed during the [[Minecraft:MINECON Earth 2017]] livestream on November 18, 2017.<ref name="Aquatic">{{ytl|mAapz_nIC_Y|The Update Aquatic Is Coming To Minecraft Spring 2018!}}, November 18, 2017</ref>
Initially, 1.13 was scheduled to be released on May 30, 2018.<ref>{{tweet|docm77|1001757427480649728|Minecraft Update Aquatic was supposed to come out today. It is pushed back to make sure all crucial bugs are fixed. Awesome!|May 30, 2018}}</ref> However, the release was pushed back to July 18, 2018 to fix critical bugs. This is the first version released in 2018.

** If a banner is destroyed, it disappears when the [[Minecraft:player]] gets close while holding the map.
** Uses the new <code>banners</code> nbt for maps.

'''[[Minecraft:Movement]]'''
* When sprinting while in water, the player now swims on the surface.
** Much faster than walking/running in water before.
** Pressing shift causes the player to rapidly dive down.
** Sprinting at the surface of water doesn't make the [[Minecraft:player]] swim, instead the player stays at the same altitude constantly.
** The players hitbox is only as large as 0.6×0.6 blocks (same as while flying with an [[Minecraft:elytra]]) while swimming.
** Vertically and horizontally, the player can fit through a one block gap like this.

'''[[Minecraft:Status effect]]s'''
* [[File:Conduit Power.png|32px]] [[Minecraft:Conduit Power]]

** Acquired by being near a powered [[Minecraft:Conduit]] while underwater.
* [[File:Dolphin's Grace.png|32px]] [[Minecraft:Dolphin's Grace]]
** Makes the player swim faster.
** Acquired by swimming near [[Minecraft:dolphin]]s.
* [[File:Slow Falling.png|32px]] [[Minecraft:Slow Falling]]
** Causes the player to descend at a much slower rate, and not take any damage when hitting the ground.
** This allows the player to jump further than normal.
*** If the player is sprinting while under the Slow Falling status effect, they are able to jump across a gap of 5 blocks, 6 with a 1-block height difference, compared to 4 with normal sprinting.
** Crops don't get destroyed if the player lands on them with the Slow Falling status effect.
** Higher levels do not change the rate of descent.

=== Command format ===
'''General'''
* Added a command UI that shows when commands are typed in the chat.
** Different components of commands are displayed in different colors.
** Errors are displayed in red without having to run the command.
* Added command suggestions for entity selectors.

* A new command parsing library known as "Brigadier".

'''Coordinates'''
* Added a new local coordinate type in commands using <code>^</code>.
** When specifying coordinates in a command, the [[Minecraft:player]] can now use <code>^</code> to specify local coordinates instead of world coordinates.
** The axes used for local coordinates are relative to the execution rotation, defaulting to <code>0,0</code> (south).
** Like world coordinates, they are by default measured from the base of an entity.

'''[[Minecraft:Tag]]s'''
* Items, blocks and functions can be "tagged" with an ID.
** Block tags can be used when testing for blocks in the world.
** Items tags can be used when testing for items in inventories.
** Function tags can be used when calling functions using commands or advancements.
*** Functions tagged in <code>minecraft:tick</code> runs every tick at the beginning of the tick.
*** Functions tagged in <code>minecraft:load</code> runs once after a (re)load.
* Tags are created using [[Minecraft:data pack]]s in <code>data/(namespace)/tags/blocks</code>, <code>data/(namespace)/tags/items</code>, and <code>data/(namespace)/tags/functions</code>.
** When overriding a tag from a different data pack, the [[Minecraft:player]] can choose to replace or append.
*** By default all tags append if another data pack created the tag.
*** Adding <code>"replace": true</code> to a tag's definition makes the tag overwrite instead.
** For example: <code>data/(namespace)/tags/blocks/foo.json</code>
** This creates a block tag called <code>(namespace):foo</code>.
** The json file contains a list of all blocks that should be "tagged".
*** This list can also contain other tags of the same type.
**** The player can add for example <code>#foo:bar</code> in a tag value list to reference another tag called <code>foo:bar</code>.
**** Self referencing is not possible.
* There are 24 vanilla tags for both items and blocks: <code>minecraft:acacia_logs</code>, <code>minecraft:banners</code>, <code>minecraft:birch_logs</code>, <code>minecraft:buttons</code>, <code>minecraft:carpets</code>, <code>minecraft:coral</code>, <code>minecraft:coral_plants</code>, <code>minecraft:dark_oak_logs</code>, <code>minecraft:doors</code>, <code>minecraft:jungle_logs</code>, <code>minecraft:logs</code>, <code>minecraft:oak_logs</code>, <code>minecraft:planks</code>, <code>minecraft:rails</code>, <code>minecraft:sand</code>, <code>minecraft:saplings</code>, <code>minecraft:spruce_logs</code>, <code>minecraft:stone_bricks</code>, <code>minecraft:wooden_buttons</code>, <code>minecraft:wooden_doors</code>, <code>minecraft:wooden_pressure_plates</code>, <code>minecraft:wooden_slabs</code>, <code>minecraft:wooden_stairs</code>, and <code>minecraft:wool</code>.
* There are 7 extra vanilla tags for blocks: <code>minecraft:anvil</code>, <code>minecraft:enderman_holdable</code>, <code>minecraft:flower_pots</code>, <code>impermeable</code>, <code>minecraft:slabs</code>, <code>minecraft:stairs</code> and <code>wall_corals</code>.
** Blocks in the <code>impermeable</code> tag are prevented from showing dripping liquid particles. By default, the tag contains [[Minecraft:glass]] and all stained glass blocks.
* There is 1 extra vanilla tag for items: <code>minecraft:boats</code>.
* Separated some of the logic for blocks and fluids.<ref>{{tweet|Dinnerbone|987293762069155841|<nowiki>Trying to extract parts of BlockState into StateHolder<T> and turn BlockStateDefinition into StateDefinition<T> so I can use the same system for liquids</nowiki>|April 20, 2018}}</ref>
** Current fluids:
*** <code>minecraft:empty</code>
*** <code>minecraft:flowing_water</code>
*** <code>minecraft:water</code>
*** <code>minecraft:flowing_lava</code>
*** <code>minecraft:lava</code>
** The fluid at a location is currently dependent on the block at the location; currently there still are water and lava blocks. <!-- i.e. this change hasn't happened yet: https://twitter.com/Dinnerbone/status/988712909315493888 -->
** Added two new fluid [[Minecraft:tag]]s: <code>minecraft:lava</code> and <code>minecraft:water</code>.
** This system is mostly internal; it cannot be directly interacted with yet.
* [[Minecraft:Advancement]] item predicates now support item tags.

'''[[Minecraft:Waterlogging]]'''
* Water can now be placed in the following blocks: chests, trapped chests, stairs, slabs, fences, walls, iron bars, glass panes, ender chests, trapdoors, ladders, and signs.
** Water can flow out of these blocks, but cannot flow into them.
** When full of water, they count as water blocks for all gameplay (such as swimming).
** Water flows out of all faces of the block except for solid faces.
* Removed the blocks <code>flowing_water</code> and <code>flowing_lava</code>.
* All of the blocks that water can be placed in now have the block state <code>waterlogged</code>.
* Blocks such as bubble column or kelp always count as a water source.
* When water spreads and would later turn into a source block, it now immediately just places a source block.
'''Other'''
* New <code>valid_spawn</code> block tag for blocks that the player can spawn on.
* There is now a distinction between scheduled "liquid ticks" and "block ticks".

== Changes ==

** Previously, the flower pot was completely empty.

=== Gameplay ===
'''Camera'''
* A smooth transition is now applied to the camera when the player sneaks, flies with an [[Minecraft:elytra]] or swims.
* A smooth transition is now applied to the camera when entering or leaving a [[Minecraft:bed]].

'''[[Minecraft:Movement]]'''

** Every ocean biome has a unique water color, and the swamp water color has been changed.
** Visibility changes per biome.

=== Command format ===
'''General'''
* Commands and functions are much faster and more efficient.
* Most commands are now more case-sensitive. Lowercase is preferable wherever possible.
** For example, this is no longer allowed: <code>/scoreboard ObJeCtIvEs ...</code>
* The output signal of a command block used to be its "success count", but now is its "result".
* Server commands ([[Minecraft:Commands/function|function]]s, console, rcon) now run from world spawn in the Overworld, instead of at <code>0,0,0</code>.
* Errors during a command are now a nicer error message (with a tool tip for more info).
* Added commands to the profiler ({{cmd|debug}}).
* Whitespaces are now allowed in entity selectors & blockstate arguments.
* Blockstate files:
** <code>"normal"</code> for blocks without block states changed to an empty string (<code>""</code>).
** Item frames now have <code>"map=false"</code> instead of <code>"normal"</code> and <code>"map=true"</code> instead of <code>"map"</code>.
** Model references no longer start at the <code>models/block/</code> folder, but instead at <code>models/</code>.

'''[[Minecraft:Command]] UI'''
* A new prototype for the command UI.

'''[[Minecraft:Function (Java Edition)|Function]]s'''
* Functions are now completely parsed and cached on load.
** This means if a command is incorrect for any reason, the player knows about it on load.

'''NBT'''
* The <code>ench</code> NBT tag of items is now called <code>Enchantments</code>, and no longer has number IDs in each compound.
* <code>Thrower</code> and <code>Owner</code> nbt keys of [[Minecraft:item entities]] are no longer strings, but are instead compounds with two longs named <code>L</code> and <code>M</code>.
* <code>owner</code> nbt keys of [[Minecraft:snowball]]s, [[Minecraft:egg]]s and [[Minecraft:ender pearl]]s are no longer strings, but are instead compounds with two longs named <code>L</code> and <code>M</code>.
* Changed all custom names (blocks, items, entities, block entities) from raw strings to JSON text components (which can be translated).
** For example, <code>/summon pig ~ ~ ~ {CustomName:"Reuben"} </code> is now <code>/summon pig ~ ~ ~ {CustomName:"\"Reuben\""} </code> or <code>/summon pig ~ ~ ~ {CustomName:"{\"text\":\"Reuben\"}"} </code>

'''Specific commands'''

'''{{cmd|advancement}}'''
* Removed <code>/advancement test</code> in favor of entity selectors.

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

'''{{cmd|clear}}'''
* The syntax has changed.
** <code>/clear [<target>] [<item>] [<nowiki><data></nowiki>] [<count>] [<nbt>]</code> is now <code>/clear [<target>] [<item>] [<count>]</code>
** See the item argument type for more details.

'''{{cmd|clone}}'''
* The syntax has changed.
** <code>/clone <begin> <end> <destination> filtered [force|move|normal] [<block>] [<nowiki><data></nowiki>]</code> is now <code>/clone <begin> <end> <destination> filtered [<block>] [force|move|normal]</code>
** <code>/clone <begin> <end> <destination> [replace|masked] [force|move|normal] [<block>] [<nowiki><data></nowiki>]</code> is now <code>/clone <begin> <end> <destination> [replace|masked] [force|move|normal]</code>

'''{{cmd|defaultgamemode}} and {{cmd|gamemode}}'''
* Now only accept string IDs, not shorthand or numeric.
** <code>/gamemode 2</code> is now <code>/gamemode adventure</code>
** <code>/defaultgamemode sp</code> is now <code>/defaultgamemode spectator</code>

'''{{cmd|difficulty}}'''
* <code>difficulty [<value>]</code> now only accepts string IDs, not shorthand or numeric.
** <code>/difficulty 2</code> is now <code>/difficulty normal</code>
** <code>/difficulty p</code> is now <code>/difficulty peaceful</code>
* [[Minecraft:Player]]s can now query for the current difficulty by using {{cmd|difficulty}} without any arguments.

'''{{cmd|effect}}'''
* The syntax has been split off, to avoid ambiguity.
** <code>/effect <entity> <effect></code> is now <code>/effect give <entity> <effect></code>
** <code>/effect <entity> clear</code> is now <code>/effect clear <entity> [<effect>]</code>
* Giving an effect now fails if it didn't actually do anything.
** Some mobs are immune (for example the [[Minecraft:ender dragon]]).
** Stronger existing effects prevent new weaker ones.

'''{{cmd|entitydata}}'''
* Removed in favor of {{cmd|data}}.

{{anchor|executechanges}}
'''{{cmd|execute}}'''
* The syntax has been split off.
** Modifier sub-commands can change how the command is run:
*** <code>/execute as <entity> <chained command></code> executes a command using the entity <code><entity></code> (but doesn't change position).
*** <code>/execute at <entity> <chained command></code> executes a command using the position, rotation, and dimension of the <code><entity></code> (but doesn't change entity).
*** <code>/execute positioned <pos> <chained command></code> executes a command using the position of <code><pos></code>.
*** <code>/execute positioned as <entity> <chained command></code> executes a command using the position (x y z) of the <code>entity</code>, but nothing else.
*** <code>/execute align <axes> <chained command></code> executes a command after aligning the current position to the block grid (rounding down), <code><axes></code> is any combination of <code>x</code> <code>y</code> and <code>z</code> (for example: <code>x</code>,<code>xz</code>,<code>zyx</code> and <code>yz</code>).
**** Examples:
***** <code>x=-1.8,y=2.3,z=5.9</code> using <code>x</code> becomes <code>x=-2,y=2.3,z=5.9</code>
***** <code>x=2.4,y=-1.1,z=3.8</code> using <code>yxz</code> becomes <code>x=2,y=-2,z=3</code> 
*** <code>/execute facing <x y z> <chained command></code> executes a command as though the executor is facing <code>x y z</code>.
*** <code>/execute facing entity <entity> (eyes|feet) <chained command></code> executes a command as though the executor is facing the entity's eyes or feet.
*** <code>/execute rotated as <entity> <chained command></code> executes a command as though the executor is rotated in the direction of the entity.
*** <code>/execute rotated <y x> <chained command></code> runs the command as though the executor is rotated in the specified direction.
*** <code>/execute in (overworld|the_end|the_nether) <chained command></code> executes a command as though the executor is in the specified dimension.
*** <code>/execute anchored (feet|eyes) <chained command></code> makes the rest of this command use feet or eyes for ^ ^ ^ coordinates or facing commands.
** Conditional sub-commands can let the [[Minecraft:player]] prevent the command from running at all:
*** <code>/execute (if|unless) block <pos> <block> <chained command></code> executes a command if (or unless) <code><pos></code> matches <code><block></code>.
*** <code>/execute (if|unless) blocks <begin> <end> <destination> (all|masked) <chained command></code> executes a command if (or unless) the region between <code><begin></code> and <code><end></code> matches <code><destination></code>.
*** <code>/execute (if|unless) entity <entity> <chained command></code> executes a command if (or unless) <code><entity></code> exists (returns 1 or more entities).
*** <code>/execute (if|unless) score <target> <targetObjective> (<|<=|=|>=|>) <nowiki><source></nowiki> <sourceObjective> <chained command></code> executes a command if (or unless) <code><target></code>'s score relates to <code><nowiki><source></nowiki></code>'s score based on the chosen criterion.
*** <code>/execute (if|unless) score <target> <objective> matches <range> <chained command></code> executes a command if (or unless) <code><target></code>'s score is in the <code>range</code> (ie <code>1</code>, <code>1..5</code>).
** As replacement for {{cmd|stats}}, a new sub-command <code>store</code> lets players store the result or success of a command somewhere:
*** <code>result</code> is the result of a command, which replaces these old stats: <code>AffectedBlocks</code>, <code>AffectedEntities</code>, <code>AffectedItems</code>, <code>QueryResult</code>.
*** <code>success</code> is how many times the command was successful. This is usually <code>0</code> or <code>1</code>, but if the command split up (for example <code>as @a</code>) then it may be more than <code>1</code>. This replaces <code>SuccessCount</code>.
*** The value is stored when the full command has finished executing.
*** If a command isn't successful (<code>success</code> is <code>0</code>), <code>result</code> is always set to <code>0</code>.
*** It is made clear what the expected result of each command is.
*** <code>/execute store (result|success) score <name> <objective> <chained command></code>
**** The value is stored into the scoreboard under <code><name></code> and <code><objective></code>.
**** The <code>objective</code> must exist, but unlike with {{cmd|stats}} the player doesn't need to set an initial value for <code><name></code>.
*** <code>/execute store (result|success) block <pos> <path> (byte|double|float|int|long|short) <scale> <chained command></code>
**** The value is stored in the nbt data at <code>path</code> of the block at <code>pos</code> as a byte, double, float, int, long, or short.
*** <code>/execute store (result|success) entity <target> <path> (byte|double|float|int|long|short) <scale> <chained command></code>
**** The value is stored in the nbt data at <code>path</code> of one <code>target</code> entity as a byte, double, float, int, long, or short.
**** Like {{cmd|data}}, <code>/execute store</code> can't modify player nbt. Nbt inside the <code>tag</code> key of items in the player's <code>Inventory</code> or <code>EnderItems</code> is an exception and can be modified by <code>/execute store</code>.<ref>{{bug|MC-123307}}</ref>
*** <code>/execute store (result|success) bossbar <id> (value|max) <chained command></code>
**** The value is stored in the <code>value</code> or <code>max</code> setting of the boss bar with ID <code>id</code>.
*** Data paths look like this: <code>foo.bar[0]."A [crazy name]".baz</code>.
**** <code>foo.bar</code> means foo's child called bar.
**** <code>bar[0]</code> means element 0 of bar.
**** "quoted strings" may be used if a name of a key needs to be escaped.
*** Examples:
**** <code>/execute store success score @a foo run say hi</code>
**** <code>/execute as <nowiki>@e[type=pig]</nowiki> at @s store success entity @s Saddle byte 1 if entity <nowiki>@p[distance=..5]</nowiki></code>
** The player can chain all sub-commands together.
*** After every sub-command the player needs to write another sub-command.
*** When the player is done with chaining sub-commands, <code>run</code> lets them write the actual command to be executed.
**** <code>/</code> is no longer allowed before the command.
*** <code>/execute as somebody at somebody run say hi</code>
** Example of old commands:
*** <code>/execute @e ~ ~ ~ detect ~ ~ ~ stone 0 say Stone!</code> is now <code>/execute as @e at @s if block ~ ~ ~ stone run say Stone!</code>
*** <code>/execute @e ~ ~ ~ detect ~ ~ ~ grass 0 summon pig</code> is now <code>/execute at @e if block ~ ~ ~ grass_block run summon pig</code>
*** <code>/execute @e ~ ~ ~ say Hello!</code> is now <code>/execute as @e run say Hello!</code>

'''{{cmd|experience}}'''
* {{cmd|xp}} is now an alias for {{cmd|experience}}.
* Split up into 3 different subcommands:
** <code>/experience add <players> <amount> [points|levels]</code>
*** Adds <code><amount></code> of either points or levels to the target <code><players></code> (defaults to points).
*** Adding points can cause players to level up, as usual.
*** Negative numbers are supported, to subtract points instead.
*** Subtracting points can cause players to level down.
** <code>/experience set <players> <amount> [points|levels]</code>
*** Sets <code><amount></code> of either points or levels on the target <code><players></code> (defaults to points).
*** The [[Minecraft:player]] cannot set more points than their current level allows.
*** When changing levels, points stay at the same percentage as the previous level.
** <code>/experience query <player> (points|levels)</code>
*** Returns either the number of points or levels on the given <code><player></code>.

'''{{cmd|fill}}'''
* The syntax has changed.
** <code>/fill <begin> <end> <block> <nowiki><data></nowiki> replace [<replaceBlock>] [<replaceData>]</code> is now <code>/fill <begin> <end> <block> replace [<filter>]</code>
** <code>/fill <begin> <end> <block> [<nowiki><data></nowiki>] [destroy|hollow|keep|outline|replace] [<nbt>]</code> is now <code>/fill <begin> <end> <block> [destroy|hollow|keep|outline|replace]</code>

'''{{cmd|function}}'''
* No longer accepts <code>[if|unless] <entity></code> arguments.
** This has been moved into {{cmd|execute}}.
** <code>/function foo if @e</code> is now <code>/execute if entity @e run function foo</code>

'''{{cmd|gamerule}}'''
* No longer accepts unknown rules ("custom gamerules").
** The [[Minecraft:player]] can use [[Minecraft:Function (Java Edition)|function]]s or [[Minecraft:scoreboard]]s as replacements, with no loss of functionality.
** Existing custom gamerules are just not accessible. Only built-in rules are available.
* Values to {{cmd|gamerule}} are now type checked (giving a string if it wants an int is a very obvious error).
* Removed the <code>gameLoopFunction</code> gamerule in favor of functions tagged in <code>minecraft:tick</code>.

'''{{cmd|give}}'''
* The syntax has changed.
** <code>/give <players> <item> [<count>] [<nowiki><data></nowiki>] [<nbt>]</code> is now <code>/give <players> <item> [<count>]</code>
** See the item argument type for more details.

'''{{cmd|kill}}'''
* A <code>target</code> is now mandatory.

'''{{cmd|list}}'''
* Can now be used in singleplayer.

'''{{cmd|locate}}'''
* The Y-coordinate is now returned as <code>~</code> instead of <code>?</code>.
* The <code>result</code> of the command, used by <code>/execute store</code>, is the absolute distance to the structure.
* Now accepts different structure names for all structures previously grouped under <code>Temple</code>: <code>Desert_Pyramid</code>, <code>Igloo</code>, <code>Jungle_Pyramid</code>, and <code>Swamp_Hut</code>.

'''{{cmd|op}}'''
* Now allows target selectors besides names.

'''{{cmd|particle}}'''
* The <code><params></code> argument has been removed, instead the parameters for particles like <code>block</code> can be specified right after the <code><name></code> argument using the new block argument.
** <code>/particle <nowiki>block polished_granite ~ ~ ~ 0 0 0 0 1</nowiki></code>
** <code>/particle <nowiki>dust 1 1 1 1 ~ ~ ~ 0 0 0 0 1</nowiki></code>
*** <code>1 1 1 1</code> are, in order, the three RGB color values (0-1) and the size of the particle.
* <code>/particle <name> <pos></code> is now a valid shortcut. <code>delta</code>, <code>speed</code>, and <code>count</code> defaults to <code>0</code>.
<div class="collapsible collapsed" data-expandtext="show" data-collapsetext="hide" style="width:400px;">
* Particle names have been changed.

** For example, <code>slot.hotbar.1</code> now is <code>hotbar.1</code>

'''{{cmd|scoreboard}}'''
* Had <code>[<dataTag>]</code> removed from its commands in favor of the <code>nbt</code> argument in entity selectors.
* <code>/scoreboard players tag</code> and <code>/scoreboard teams</code> removed. Replaced by {{cmd|tag}} and {{cmd|team}} respectively.
* <code>/scoreboard players test</code> removed in favor of <code>execute (if|unless) score</code>, entity selectors and <code>/scoreboard players get <target> <objective></code>

** <code>/setblock <pos> <block> [<nowiki><data></nowiki>] [<mode>] [<nbt>]</code> is now <code>/setblock <pos> <block> [<mode>]</code>
** See the block argument type for more details.

'''{{cmd|stats}}'''
* Removed. Now part of {{cmd|execute}}.
* The new {{cmd|execute}} one isn't a direct replacement, the behavior has changed:
** It's now per-command, instead of per-entity or per-block.
** There's only <code>result</code> and <code>success</code>, which covers all the old stat types.

'''{{cmd|stopsound}}'''
* <code>*</code> can now be used instead of <code>source</code> to stop all sounds with a certain name, across all sources.

'''{{cmd|tag}}'''
* Replaces <code>/scoreboard players tag</code>.
* Keeps the same syntax.
** <code>/tag <players> add <tag></code> to add <code><tag></code> to <code><players></code>.
** <code>/tag <players> remove <tag></code> to remove <code><tag></code> from <code><players></code>.
** <code>/tag <players> list</code> to list all tags on <code>players</code>.

'''{{cmd|team}}'''
* Replaces <code>/scoreboard teams</code>.
* Keeps the same syntax.
** <code>/team add <team> [<displayname>]</code>
** <code>/team empty <team></code>
** <code>/team join <team> [<members>]</code>
** <code>/team leave [<members>]</code>
** <code>/team list [<team>]</code>
** <code>/team modify <team> <option> <value></code>
** <code>/team modify <team> [<displayname>]</code>
* Teams can now have a prefix and a suffix.
** <code>/team modify <team> prefix <prefix></code>
** <code>/team modify <team> suffix <suffix></code>
* Team names are now text components, not raw strings.

'''{{cmd|testfor}}, {{cmd|testforblock}} and {{cmd|testforblocks}}'''
* Removed. Now part of {{cmd|execute}}.

'''{{cmd|toggledownfall}}'''
* Removed. It was always used to stop the rain, but rain usually quickly returned.
* Use {{cmd|weather}}.

'''{{cmd|tp}} and {{cmd|teleport}}'''
* {{cmd|tp}} is now an alias of {{cmd|teleport}} (much like {{cmd|w}}, {{cmd|msg}} and {{cmd|tell}}).
* {{cmd|teleport}} has been simplified a bit, to avoid ambiguity.
** <code>/teleport <entity></code> doesn't allow rotation or facing, teleports the [[Minecraft:player]] to the entity.
** <code>/teleport <x y z></code> doesn't allow rotation or facing, teleports the [[Minecraft:player]] to the position.
** <code>/teleport <victim> <entity></code> doesn't allow rotation or facing, teleports victim to entity.
** <code>/teleport <victim> <x y z> [yRot xRot]</code> teleports victim to that position with optional rotation.
** <code>/teleport <victim> <x y z> facing [xFacing yFacing zFacing]</code> teleports victim to that position facing another position.
** <code>/teleport <victim> <x y z> facing entity <entityFacing> [feet|eyes]</code> teleports victim to that position facing an entity's feet or eyes (default feet).
** Teleporting to an entity in another dimension is now allowed.

'''{{cmd|trigger}}'''
* <code>/trigger <objective></code> is a new syntax as a shortcut for <code>/trigger <objective> add 1</code>.
'''{{cmd|weather}}'''
* If a time isn't specified, it now defaults to 5 minutes (previously random).

'''Team'''
* Option <code>friendlyfire</code> capitalization changed to <code>friendlyFire</code>.

'''Argument types'''

'''[[Minecraft:Target selector]]s'''
* More error handling has been introduced.
** Things like <code>limit=0</code>, <code>level=-10</code>, <code>gamemode=purple</code> are not allowed.
* Arguments may now be quoted.
* There are no longer separate "min" and "max" values; instead ranges are supported.
** <code>level=10</code> is level 10.
** <code>level=10..12</code> is level 10, 11 or 12.
** <code>level=5..</code> is anything level 5 or above.
** <code>level=..15</code> is anything level 15 or below.
* The arcane shorthand names have been renamed.
** <code>m</code> -> <code>gamemode</code>
** <code>l</code> or <code>lm</code> -> <code>level</code>
** <code>r</code> or <code>rm</code> -> <code>distance</code>
** <code>rx</code> or <code>rxm</code> -> <code>x_rotation</code>
** <code>ry</code> or <code>rym</code> -> <code>y_rotation</code>
** <code>c</code> -> <code>limit</code>
* <code>x</code>, <code>y</code>, <code>z</code>, <code>distance</code>, <code>x_rotation</code> and <code>y_rotation</code> are now doubles and allow values like <code>12.34</code>
** <code>x</code> and <code>z</code> are no longer center-corrected.
*** This means <code>x=0</code> no longer equates to <code>x=0.5</code>.
* <code>gamemode</code> (previously <code>m</code>) no longer allows numerical or shorthand IDs.
* <code>limit</code> (previously <code>c</code>) no longer allows negative values.
** Use <code>sort=furthest</code> instead.
* The <code>name</code> argument now supports spaces (as long as it's quoted).
* Multiple of the same argument in target selectors is now possible.
** <code>tag=foo,tag=bar,tag=!baz</code> matches someone with <code>foo</code>, <code>bar</code> and not <code>baz</code>.
** <code>type=!cow,type=!chicken</code> matches something that isn't a cow and isn't a chicken.
** <code>type=cow,type=chicken</code> isn't allowed, because something cannot both be a cow and chicken.
* The player can specify the sorting.
** <code>sort=nearest</code> is the old default, sorting by distance (default for <code>@p</code>)
** <code>sort=furthest</code> is the reverse of that (previously, players would use <code>c=-5</code> for this)
** <code>sort=random</code> for random sorting (default for <code>@r</code>)
** <code>sort=arbitrary</code> is a new option to not sort the result (default for <code>@e</code>, <code>@a</code>)
* Specifying scores now looks like <code>scores={foo=1,bar=1..5}</code>
* Players can test for advancements with <code>advancements={foo=true,bar=false,custom:something={criterion=true}}</code>
** <code>true</code> for "they completed the advancement", <code>false</code> for "they have not completed the advancement"
** Alternatively, pass a block of specific criteria to test for (again, <code>true</code> or <code>false</code>)

'''[[Minecraft:Block]]s'''
* Wherever a <code><block></code>, optionally <code><nowiki>[<data>]</nowiki></code> and optionally <code>[<nbt>]</code> was required, it's now a single <code><block></code> argument that looks like this:
** <code>stone</code>
** <code>minecraft:redstone_wire[power=15,north=up,south=side]</code>
** <code>minecraft:jukebox{RecordItem:{...}}</code>
** <code>minecraft:furnace[facing=north]{BurnTime:200}</code>
* ID is required (though just as before, if namespace isn't set it defaults to <code>minecraft:</code>).
* States are inside <code>[]</code>, comma-separated and must be properties/values supported by the blocks. They are optional.
** <code>minecraft:stone[doesntexist=purpleberry]</code> is a syntax error, because <code>stone</code> doesn't have <code>doesntexist</code>.
** <code>minecraft:redstone_wire[power=tuesday]</code> is a syntax error, because <code>redstone_wire</code>'s <code>power</code> is a number between 0 and 15.
* NBT tag is inside {}, and works just like players would expect. It's optional.
* In the context of "conditions"/testing for blocks, only the states the player provided are tested.
** If players test <code>redstone_wire[power=15]</code>, it only checks power, but ignores other states such as <code>north</code>.
* In the context of setting blocks, any states the player provided are set, but anything missed out defaults depending on the block.
** If players set <code>redstone_wire[power=15]</code>, it sets <code>power</code> to 15, but <code>north</code> is a default value (in this case, set to <code>none</code>).
* There is no such thing as block data value in 1.13. It's either a different block, or a state.

'''[[Minecraft:Item]]s'''
* Wherever an <code><item></code>, optionally <code><nowiki>[<data>]</nowiki></code> and optionally <code>[<nbt>]</code> was required, it's now a single <code><item></code> argument that looks like this:
** <code>stone</code>
** <code>minecraft:stick{display:{Name:"\"Stick of Untruths\""}}</code>
* ID is required (though just as before, if namespace isn't set it defaults to <code>minecraft:</code>).
* NBT tag is inside {}, and works just like players would expect. It's optional.
* There is no such thing as item data value or item damage value in 1.13.
** Damage, where applicable, is a property in nbt.
** Any other information is either a separate item or a property in nbt.

=== General ===
'''[[Minecraft:The Flattening]]'''
* Numeric block metadata completely phased out in favor of block states.
* Split, merged, created, deleted, and renamed a lot of blocks, blockstates and items.
** 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 <code>tag</code> tag and is only used by tools and armor; maps use a <code>map</code> tag.
*** The damage predicate has been reversed - 0.6 now means 60% durability remaining, not 60% broken
** Files and commands no longer use <code>data</code> or <code>set_data</code>.
* Structures do not run an upgrade path for this.
** To update structures, load them all in 1.12, then update to 1.13 and save all structures again.

'''[[Minecraft:Title screen]]'''
* New title screen background, featuring many of the structures, blocks, and mobs that were added in the Update Aquatic.
** The menu panorama uses seed <code>1458140401</code> at coordinates X=1553, Y=58, Z=-1162
* The comma is replaced with a dot in the copyright notice.

'''[[Minecraft:Advancement]]s'''
* Advancement descriptions now have colors:
** Normal and goal advancements have green descriptions.
** Challenge advancements have purple descriptions.

'''[[Minecraft:Controls]]'''
* The name of keybindings now describes the actual key (e.g. 'LBUTTON' -> 'Left Button', 'BACKSLASH' -> '\')

'''[[Minecraft:Creative inventory]]'''
* Because of [[Minecraft: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]]s are added to the inventory under the ''Decoration Blocks'' group. Additionally, blank [[Minecraft:firework rocket]]s are added to the ''Miscellaneous'' group.

'''[[Minecraft:Credits]]'''
* Updated the credits list to include all of the Mojang staff.

'''[[Minecraft:Debug screen]]'''
* '''Left side:'''
** Added "Looking at liquid" row. Displays the targeted fluid's coordinates.
** "Looking at" row has been renamed "Looking at block" and now targets through liquids.
* '''Right side:'''
** "Targeted Block" information now targets through fluids.
** "Targeted Block" now displays information for blocks up to 16 blocks away.

'''Fonts'''
* The Latin extended alphabet, along with Greek and Cyrillic, have been given their own "textured" font. However, some characters (such as kanji and script) still use the unicode font.
* Fonts are now saved as [[Minecraft:wikipedia:TrueType|TrueType]] font files.

'''[[Minecraft:Missing texture]]'''
* Changed from {{pximg|Missing Texture JE3.png|64px}} to {{pximg|Missing Texture JE4.png|64px}}, shifting the positions of each constituent square.

'''[[Minecraft:Music]]'''
* Three brand new pieces of underwater music by [[Minecraft:C418]] have been added:
** ''Shuniji'', ''Dragon Fish'' and ''Axolotl''.
** Their ID for commands is <code>music.under_water</code>.

'''[[Minecraft:Options]]'''
* Removed 3D Anaglyph completely.
* Option <code>Fullscreen resolution</code> capitalization changed to <code>Fullscreen Resolution</code>.
* Values for GUI scale has been renamed from "Small", "Medium" and "Large" to 1,2 and 3. GUI scaling also detects the resolution of monitors and offers even higher scaling options (4 for 1080p, 5 for 4k and so on).

'''[[Minecraft:Particles]]'''
* Optimized particle rendering slightly.
* Dripping
** Changed which blocks show dripping liquids.
** Drip particles are now generated by [[Minecraft:waterlog]]ged blocks where appropriate.<ref>{{bug|MC-127025}}</ref>
** Drip particles now snap to the hitbox of the block they appear on.<ref>{{bug|MC-1390}}</ref>
** Added a new block [[Minecraft:tag]] to prevent all solid [[Minecraft:glass]] blocks from showing dripping liquid particles. See [[#General|Tags]].

'''[[Minecraft:Recipe]]s'''
* Custom recipes can now be loaded from data packs in <code>data/(namespace)/recipes/(name).json</code>
* Added a recipe book for the furnace.
* Furnace recipes have been moved to JSON files.
** They use <code>"type": "smelting"</code>.
** <code>cookingtime</code> is used to determine the time it should take to smelt an item in the furnace.
** <code>experience</code> 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:Resource pack]]s'''
{{Resource pack format/value|4}}

'''[[Minecraft:Statistics]]'''
* 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>.
'''Tooltips'''
* Added (and fixed) [[Minecraft:rarity]] values for certain items. [[Minecraft:Item]]s with a rarity value have their [[Minecraft:hotbar]] tooltips, which are displayed when scrolling over them in the hotbar, displayed as their respective colors when highlighted, rather than just being white.<ref>{{bug|MC-130145}}</ref>
