1.13, also known as Update Aquatic[1], is an upcoming major update to Minecraft: Java Edition set to be released in Q2 2018. It will focus mainly on ocean content, bug fixes, technical features, and optimization.[3][4] This update was originally going to be released as two separate updates with 1.13, originally named Technically Updated, having the technical changes and 1.14, originally named Update Aquatic, having all the ocean features.[1]
Additions
General
- Like resource packs, but for loot tables, advancements, functions, structures, recipes and tags.
- Used by placing them into the
datapacksfolder of a world.
- Used by placing them into the
- Data packs are
.zipfiles or folders, with apack.mcmetain the root. See: Tutorials/Creating a resource pack#pack.mcmeta. The packs are located in(world)/datapacks/. - Structures will load from
(world)/generated/structures/(namespace)/(file).nbtbefore checking data packs.- However, this directory should not be used to distribute structures. Instead, move these files into data packs.
- Reloadable using
/reload. - Structure:
pack.mcmeta,datafolder containing a namespace folder determining the namespace of its contents- A namespace should only contain the following symbols:
0123456789abcdefghijklmnopqrstuvwxyz-_ - Inside the namespace folder, there can be folders for
functions,loot_tables,advancements,structures,recipesandtags.
- A namespace should only contain the following symbols:
- 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
minecraft:tickwill run every tick at the beginning of the tick. - Functions tagged in
minecraft:loadwill run once after a (re)load.
- Functions tagged in
- Tags are created using data packs in
data/(namespace)/tags/blocks,data/(namespace)/tags/items, anddata/(namespace)/tags/functions.- When overriding a tag from a different data pack, you can choose to replace or append.
- By default all tags append if another data pack created the tag.
- Adding
"replace": trueto your tag definition will make the tag overwrite instead.
- For example:
data/(namespace)/tags/blocks/foo.json - This will create a block tag called
(namespace):foo. - The json file contains a list of all blocks that should be "tagged".
- This list can also contain other tags of the same type.
- You can add for example
#foo:barin a tag value list to reference another tag calledfoo:bar. - Self referencing is not possible.
- You can add for example
- This list can also contain other tags of the same type.
- When overriding a tag from a different data pack, you can choose to replace or append.
- There are 10 default tags for both items and blocks:
minecraft:buttons,minecraft:carpets,minecraft:doors,minecraft:logs,minecraft:planks,minecraft:saplings,minecraft:stone_bricks,minecraft:wooden_buttons,minecraft:wooden_doorsandminecraft:wool - There are 3 extra default tags for blocks that don't have an equivalent for items:
minecraft:anvil,minecraft:flower_pots, andminecraft:enderman_holdable. - Advancement item predicates now support item
tags.
- Added the
set_namefunction to loot tables.
- Added a death message for when the player is blown up by a bed in the nether or end.
- "Player was killed by [Intentional Game Design]"
- Clicking on "[Intentional Game Design]" opens a link to MCPE-28723.
- "Player was killed by [Intentional Game Design]"
- Added a death message for when a mob or player causes another player to die in the void.
- "Player didn't want to live in the same world as Player/Mob"
- FS (Fullscreen) Resolution
- Is used to change the resolution.
- An option in chat settings to toggle automatic command suggestions (defaults on, otherwise hit tab to bring them up).
- Options when editing a world to make a backup and open the backups folder.
Commands
- General
- A command UI when typing commands in the chat.
- Different components of commands will be displayed in different colors.
- Errors will be displayed in red without having to run the command.
- An
nbtargument in target selectors. - A new command parsing library known as brigadier.
- Coordinates
- Added a new local coordinate type in commands using
^.- When specifying coordinates in a command, you can now use
^to specify local coordinates instead of world coordinates. - The axes used for local coordinates are relative to the execution rotation, defaulting to
0,0(south). - Like world coordinates, they are by default measured from the base of an entity.
- The syntax is:
^left ^up ^forwards left/up/forwardsis the amount of blocks in the specified direction.
- When specifying coordinates in a command, you can now use
- Specific commands
/data
- A command that allows the player to get, merge, and remove entity and block nbt data
/data get block <pos> [<path>] [<scale>]- Will return the NBT data from the block at
pos. Apathcan be specified to only retrieve that nbt data. Numeric values will be set as theresultof the command, strings will set set the length of the string as theresult, lists will set the number of elements in the list as theresult, and compounds will set the number of tags that are directly in that compound as theresult. An optionalscalecan be provided to scale the number retrieved.
- Will return the NBT data from the block at
/data get entity <target> [<path>] [<scale>]- Will return the NBT data from one
targetentity. Apathcan be specified to only retrieve that nbt data. Numeric values will be set as theresultof the command, strings will set set the length of the string as theresult, lists will set the number of elements in the list as theresult, and compounds will set the number of tags that are directly in that compound as theresult. An optionalscalecan be provided to scale the number retrieved.
- Will return the NBT data from one
/data merge block <pos> <nbt>- Will merge the block nbt data at
poswith the specifiednbtdata.
- Will merge the block nbt data at
/data merge entity <target> <nbt>- Will merge the entity nbt data from
targetwith the specifiednbtdata. Merging player nbt data is not allowed.
- Will merge the entity nbt data from
/data remove block <pos> <path>- Will remove nbt data at
pathfrom the block atpos.
- Will remove nbt data at
/data remove entity <target> <path>- Will remove nbt data at
pathfrom onetargetentity. Removing player nbt data is not allowed.
- Will remove nbt data at
- Data paths look like this:
foo.bar[0]."A [crazy name]".baz.foo.barmeans foo's child called bar.foo[0]means element 0 of foo.- "quoted strings" may be used if a name of a key needs to be escaped.
- Examples of old commands:
/entitydata <target> {}is now/data get entity <target>/blockdata <pos> <nbt>is now/data merge block <pos> <nbt>
- Examples of new functionalities:
- A command to control loaded data packs.
- Has the following subcommands:
enable <name>- will enable the specific pack.disable <name>- will disable the specific pack.list [available|enabled]- will list all data packs, or only the available/enabled ones.
- Data packs are enabled by default, but if you disable it you can re-enable it with these commands:
enable <name>- will enable the specific pack, putting it in its default position.enable <name> first- will enable the specific pack, putting it before any other pack (lowest priority)enable <name> last- will enable the specific pack, putting it after any other pack (highest priority)enable <name> before <existing>- will enable the specific pack, putting it before (lower priority) <existing> packenable <name> after <existing>- will enable the specific pack, putting it after (higher priority) <existing> pack
/bossbar create <id> <name>will create a boss bar.idis used to target the boss bar and is in the formnamespace:name, for example:foo:bar. If nonamespaceis specified it defaults tominecraft.nameis the display name of the boss bar and only accepts a JSON text component.
/bossbar set <id> name <name>will change the name of the boss bar./bossbar set <id> color <color>will change the color of the text (if no color was specified as part of a text component) and the boss bar, defaults towhite./bossbar set <id> style <style>will change the style of the boss bar, defaults toprogress.- Available options are:
notched_6,notched_10,notched_12,notched_20, andprogress. notchedwill set the amount of segments.progresswill set the amount of segments to 1.
- Available options are:
/bossbar set <id> value <value>will change the current value of the boss bar, defaults to0./bossbar set <id> max <max>will change the maximum value of the boss bar, defaults to100./bossbar set <id> visible <visible>will change the visibility of the boss bar, defaults totrue/bossbar set <id> players <players>will change which players can see the boss bar, defaults to none./bossbar remove <id>will remove the boss bar./bossbar listwill display a list of created boss bars./bossbar get <id> (max|players|value|visible)will return the requested setting as aresultof the command.
- Added
facing./teleport [<targets>] (<location>|<destination>) facing (<facingEntity>|<facingLocation>)- Will rotate an entity to face either an entity or a location.
/time
- Added
noonandmidnightto/time set.
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 spit out 4 pumpkin seeds.
Items
- An item form for bark blocks for all six types of wood.
- 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.
- A model for petrified oak slab - the old wood slab that acts like a stone slab.
Changes
General
- 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
white_woolinstead ofwool:0 - Damage has been moved to the
tagtag and is only used by tools and armor; maps use amaptag. - Files and commands no longer use
dataorset_data.
- Blocks and items previously differing because of damage value have gotten their own id, for example
- Structures do not run an upgrade path for this.
- To update your structures, load them all in 1.12, then update to 1.13 and save all structures again.
- Custom recipes can now be loaded from data packs in
data/(namespace)/recipes/(name).json
- 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. Additionally, blank firework rockets are added to the Miscellaneous group.
- The name of keybindings now describes the actual key (e.g. 'LBUTTON' -> 'Left Button', 'BACKSLASH' -> '\')
- Removed 3D Anaglyph completely
- Updated format number
- The default resource pack can now be moved up and down on the resource pack selection screen.
- Statistics are being updated.
stat.(stat)is nowminecraft.custom:minecraft.(stat).stat.(stat).minecraft.(block/item/entity ID)is nowminecraft.(stat):minecraft.(block/item/entity ID).
- Other
- Game library updates
- Upgraded to LWJGL 3
- Loading or creating a world shows the percentages of the loading stages.
Preparing spawn areanow shows as a loading stage.
- Crash reports now list what data packs are enabled.
- Data generators are now exposed, you can get a dump of all blocks/items/commands/etc from the game without opening it up.
- Changed translation files from
.lang (key=value)to.json ("key": "value").- Now supports newlines.
Commands
- 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:
/scoreboard ObJeCtIvEs ...
- For example, this is no longer allowed:
- The output signal of a command block used to be its "success count", but now is its "result".
- Server commands (functions, console, rcon) now run from world spawn in the overworld, instead of at
0,0,0. - Errors during a command are now a nicer error message (with a tool tip for more info).
- Added commands to the profiler (/debug).
- NBT
ThrowerandOwnernbt keys of item entities are no longer strings but are instead compounds with two longs namedLandM.ownernbt keys of snowballs, eggs and ender pearls are no longer strings but are instead compounds with two longs namedLandM.- Changed all custom names (blocks, items, entities, block entities) to translatable text components.
- Command UI
- A new prototype for the command UI.
- Functions are now completely parsed and cached on load.
- This means if a command is incorrect for any reason, the player will know about it on load.
- Specific Commands
- Removed
/advancement testin favor of entity selectors.
- Removed in favor of
/data.
- The syntax of
/clearhas changed.
- The syntax of
/clonehas been changed./clone <begin> <end> <destination> filtered [force|move|normal] [<block>] [<data>]will become/clone <begin> <end> <destination> filtered [<block>] [force|move|normal]/clone <begin> <end> <destination> [replace|masked] [force|move|normal] [<block>] [<data>]will become/clone <begin> <end> <destination> [replace|masked] [force|move|normal]
/defaultgamemodeand/gamemode
- Now only accepts string IDs, not shorthand or numeric.
/gamemode 2will become/gamemode adventure/defaultgamemode spis now/defaultgamemode spectator
/difficulty [<value>]now only accepts string IDs, not shorthand or numeric./difficulty 2is now/difficulty normal/difficulty pis now/difficulty peaceful
- You can now query for the current difficulty by using
/difficultywithout any arguments.
- The syntax of
/effecthas been split off, to avoid ambiguity. - Giving an effect will now fail if it didn't actually do anything.
- Some mobs are immune (for example an ender dragon).
- Stronger existing effects prevent new weaker ones.
- Removed in favor of
/modifyitem.
- Removed in favor of
/data.
- The syntax of
/executehas been split off.- Modifier sub-commands can change how the command is run:
/execute as <entity> <chained command>executes a command using the entity<entity>(but doesn't change position)./execute at <entity> <chained command>executes a command using the position, rotation, and dimension of the<entity>(but doesn't change entity)./execute positioned <pos> <chained command>executes a command using the position of<pos>./execute positioned as <entity> <chained command>executes a command using the position (x y z) of theentitybut nothing else./execute align <axes> <chained command>executes a command after aligning the current position to the block grid (rounding down),<axes>is any combination ofxyandz(for example:x,xz,zyxandyz).- Examples:
x=-1.8,y=2.3,z=5.9usingxwill becomex=-2,y=2.3,z=5.9x=2.4,y=-1.1,z=3.8usingyxzwill becomex=2,y=-2,z=3
- Examples:
/execute facing <x y z> <chained command>executes a command as though the executor is facingx y z./execute facing entity <entity> (eyes|feet) <chained command>executes a command as though the executor is facing the entity's eyes or feet./execute rotated as <entity> <chained command>executes a command as though the executor is rotated in the direction of the entity./execute rotated <y x> <chained command>will run the command as though the executor is rotated in the specified direction./execute in (overworld|the_end|the_nether) <chained command>executes a command as though the executor is in the specified dimension./execute anchored (feet|eyes) <chained command>will make the rest of this command use feet or eyes for ^ ^ ^ coordinates or facing commands.
- Conditional sub-commands can let you prevent the command from running at all:
/execute (if|unless) block <pos> <block> <chained command>executes a command if (or unless)<pos>matches<block>./execute (if|unless) blocks <begin> <end> <destination> (all|masked) <chained command>executes a command if (or unless) the region between<start>and<end>matches<destination>./execute (if|unless) entity <entity> <chained command>executes a command if (or unless)<entity>exists (returns 1 or more entities)./execute (if|unless) score <target> <targetObjective> (<|<=|=|>=|>) <source> <sourceObjective> <chained command>executes a command if (or unless)<target>'s score relates to<source>'s score based on the chosen criterium./execute (if|unless) score <target> <objective> matches <range> <chained command>executes a command if (or unless)<target>'s score is in therange(ie1,1..5).
- As replacement for
/stats, a new sub-commandstorelets you store the result or success of a command somewhere:resultis the result of a command, which replaces these old stats:AffectedBlocks,AffectedEntities,AffectedItems,QueryResult.successis how many times the command was successful. This is usually0or1, but if the command split up (for exampleas @a) then it may be more than1. This replacesSuccessCount.- The value will be stored when the full command has finished executing.
- If a command isn't successful (
successis0),resultwill always be set to0. - It will be made clear what the expected result of each command is.
/execute store (result|success) score <name> <objective> <chained command>- The value is stored into the scoreboard under
<name>and<objective>. - The
objectivemust exist, but unlike with/statsyou don't need to set an initial value for<name>.
- The value is stored into the scoreboard under
/execute store (result|success) block <pos> <path> (byte|double|float|int|long|short) <scale> <chained command>- The value is stored in the nbt data at
pathof the block atposas a byte, double, float, int, long, or short.
- The value is stored in the nbt data at
/execute store (result|success) entity <target> <path> (byte|double|float|int|long|short) <scale> <chained command>/execute store (result|success) bossbar <id> (value|max) <chained command>- The value is stored in the
valueormaxsetting of the boss bar with IDid.
- The value is stored in the
- Data paths look like this:
foo.bar[0]."A [crazy name]".baz.foo.barmeans foo's child called bar.foo[0]means element 0 of foo.- "quoted strings" may be used if a name of a key needs to be escaped.
- Examples:
- You can chain all sub-commands together.
- After every sub-command you need to write another sub-command.
- When you're done with chaining sub-commands,
runlets you write the actual command to be executed./is no longer allowed before the command.
/execute as somebody at somebody run say hi
- Example of old commands:
- Modifier sub-commands can change how the command is run:
/xpis now an alias for/experience.- Split up into 3 different subcommands:
/experience add <players> <amount> [points|levels]- Adds
<amount>of either points or levels to the target<players>(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.
- Adds
/experience set <players> <amount> [points|levels]- Sets
<amount>of either points or levels on the target<players>(defaults to points). - You cannot set more points than their current level allows.
- When changing levels, the points will stay at the same percentage as the previous level.
- Sets
/experience query <player> (points|levels)- Returns either the number of points or levels on the given
<player>.
- Returns either the number of points or levels on the given
/fill
- The syntax of
/fillhas been changed.
/functionno longer accepts[if|unless] <entity>arguments.
/gameruleno longer accepts unknown rules ("custom gamerules").- You can use functions or scoreboards as replacements, with no loss of functionality.
- Existing custom gamerules will just not be accessible. Only built-in rules will be available.
- Values to
/gameruleare now type checked (giving a string if it wants an int is a very obvious error). - Removed the
gameLoopFunctiongamerule in favor of functions tagged inminecraft:tick.
/give
- The syntax of
/givehas changed.
/kill
- A
targetis now mandatory
- The y-coordinate is now returned as
64instead of?. - The
resultof the command, used by/execute store, will be the absolute distance to the structure.
- The
<params>argument has been removed, instead the parameters for particles likeblockcan be specified right after the<name>argument using the new block argument. /particle <name> <pos>is now a valid shortcut.delta,speed, andcountwill default to0
- Particle names have been changed.

- Will Tab ↹ auto-complete custom sound events.
- The syntax of
/replaceitemhas changed./replaceitem block <pos> <slot> <item> [<count>] [<data>] [<nbt>]is now/replaceitem block <pos> <slot> <item> [<count>]/replaceitem entity <target> <slot> <item> [<count>] [<data>] [<nbt>]is now/replaceitem entity <target> <slot> <item> [<count>]- See the item argument type for more details.
- The
slotargument no longer requiresslot..- For example,
slot.hotbar.1now ishotbar.1
- For example,
/scoreboardhad[<dataTag>]removed from its commands in favor of thenbtargument in entity selectors./scoreboard players tagand/scoreboard teamsremoved. Replaced by/tagand/teamrespectively./scoreboard players testremoved in favor of/execute (if|unless) score, entity selectors and/scoreboard players get <target> <objective>.
- The syntax of
/setblockhas changed.
- Removed. Now part of
/execute. - The new
/executeone isn't a direct replacement, the behavior has changed:- It's now per-command, instead of per-entity or per-block.
- There's only
resultandsuccess, which covers all the old stat types.
*can now be used instead ofsourceto stop all sounds with a certain name, across all sources.
/tag
- Replaces
/scoreboard players tag. - Keeps the same syntax.
/team
- Replaces
/scoreboard teams. - Keeps the same syntax.
/testfor,/testforblockand/testforblocks
- Removed. Now part of
/execute.
- Removed. It was always used to stop the rain, but rain usually quickly returned.
- Use
/weather.
/tpis now an alias of/teleport(much like/w,/msgand/tell)./teleporthas been simplified a bit, to avoid ambiguity./teleport <entity>doesn't allow rotation or facing, will teleport you to the entity./teleport <x y z>doesn't allow rotation or facing, will teleport you to the position./teleport <victim> <entity>doesn't allow rotation or facing, will teleport victim to entity./teleport <victim> <x y z> [yRot xRot]will teleport you to that position with optional rotation./teleport <victim> <x y z> facing [xFacing yFacing zFacing]will teleport you to that position facing another position./teleport <victim> <x y z> facing entity <entityFacing> [feet|eyes]will teleport you to that position facing an entity's feet or eyes (default feet).- Teleporting to an entity in another dimension is now allowed.
- If you don't specify a time, it now defaults to 5 minutes (previously random).
- Argument Types
- More error handling has been introduced.
- Arguments may now be quoted.
- Things like
limit=0,level=-10,gamemode=purpleare not allowed.
- Things like
- There's no longer a "min" and "max" separate values, we instead support ranges.
level=10is level 10level=10..12is level 10, 11 or 12level=5..is anything level 5 or abovelevel=..15is anything level 15 or below
- The arcane shorthand names have been renamed.
m->gamemodelorlm->levelrorrm->distancerxorrxm->x_rotationryorrym->y_rotationc->limit
x,y,z,distance,x_rotation,y_rotationare now doubles and allow values like12.34xandzare no longer center-corrected.- This means
x=0no longer equates tox=0.5.
- This means
gamemode(previouslym) no longer allows numerical or shorthand IDs.limit(wasc) No longer allows negative values.- Use
sort=furthestinstead.
- Use
- The
nameargument now supports spaces (as long as it's quoted). - Multiple of the same argument in target selectors is now possible.
tag=foo,tag=bar,tag=!bazmatches someone withfoo,barand notbaz.type=!cow,type=!chickenmatches something that isn't a cow and isn't a chicken.type=cow,type=chickenisn't allowed, because something cannot both be a cow and chicken.
- You can specify the sorting.
sort=nearestis the old default, sorting by distance (default for@p)sort=furthestis the reverse of that (previously you'd usec=-5for this)sort=randomfor random sorting (default for@r)sort=arbitraryis a new option to not sort the result (default for@e,@a)
- Specifying scores now looks like
scores={foo=1,bar=1..5} - You can test for advancements with
advancements={foo=true,bar=false,custom:something={criterion=true}}truefor "they completed the advancement",falsefor "they have not completed the advancement"- Alternatively, pass a block of specific criteria to test for (again,
true/false)
- Wherever a
<block>, optionally[<data>]and optionally[<nbt>]was required, it's now a single<block>argument that looks like this:stoneminecraft:redstone_wire[power=15,north=up,south=side]minecraft:jukebox{RecordItem:{...}}minecraft:furnace[facing=north]{BurnTime:200}
- ID is required (though just as before, if namespace isn't set it defaults to
minecraft:). - States are inside
[], comma-separated and must be properties/values supported by the blocks. They are optional.minecraft:stone[doesntexist=purpleberry]is a syntax error, becausestonedoesn't havedoesntexist.minecraft:redstone_wire[power=tuesday]is a syntax error, becauseredstone_wire'spoweris a number between 0 and 15.
- NBT tag is inside {}, and works just like you'd expect. It's optional.
- In the context of "conditions"/testing for blocks, only the states you provided will be tested.
- If you test
redstone_wire[power=15], it only checks power but ignores other states such asnorth.
- If you test
- In the context of setting blocks, any states you provided will be set but anything missed out will default depending on the block.
- If you set
redstone_wire[power=15], it will setpowerto 15 butnorthwill be a default value (in this case, set tonone).
- If you set
- There is no such thing as block data value in 1.13. It's either a different blocks, or a state.
- Wherever an
<item>, optionally[<data>]and optionally[<nbt>]was required, it's now a single<item>argument that looks like this:stoneminecraft:stick{display:{Name:"Stick of Untruths"}}
- ID is required (though just as before, if namespace isn't set it defaults to
minecraft:). - NBT tag is inside {}, and works just like you'd expect. It's optional.
- There is no such thing as item data value or item damage value in 1.13.
- Damage, where applicable, is being moved into nbt.
- Any other information is either a separate item or a property in nbt.
World generation
- Now generates with a mushroom in the flower pot.
- Previously, it was completely empty.
Blocks
- The upper limit of the block ID has dissappeared.
- 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 afterwards 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.
- Monster eggs will now break instantly, no matter the tool.
- When broken with Silk Touch, the non-infested counterpart of the block will drop.
- Bark can now be crafted. 4 logs in a square yield 3 bark.
- Multiple vines facing different directions, including on the bottom of blocks, can now be placed in the same block space.
Mobs
- The model has been changed to be more consistent with other mobs.[6]
- Some animations like opening its mouth when grazing have been removed from the model as well.
Non-mob entities
- Item frames can now be put on floors and ceilings.
- Paintings now use a namespaced ID for their motive.
- Bobbers created by fishing rods got an entity ID,
fishing_bobber.- This ID can only be used for testing, summoning is not possible.
