23w31a is the first snapshot for Java Edition 1.20.2, released on August 2, 2023,^[1] which adds the "Villager Trade Rebalance" experimental toggle, adds /random command and fixes bugs.

/random

• A new command for randomizing values and controlling random sequences.
  • Syntaxes:
    • /random (value|roll) <range> [<sequence>]: draw a random value.
    • /random reset (*|<sequence>) [<seed>] [<includeWorldSeed>] [<includeSequenceId>]: control random sequences.
  • Arguments:
    • range: A range of values to randomize between, inclusively. For instance, 1..6 is a regular D6 roll.
    • sequence: The name of a random sequence to sample or reset.
      • In /random reset, * refers to all random sequences.
    • seed: A seed to use for the random sequence after reset.
    • includeWorldSeed: A boolean specifying whether to include the world seed when seeding the sequence. Defaults to true.
      • When false, it means the sequence evaluates to the same regardless of which world the command is run in.
    • includeSequenceId: A boolean specifying whether to include the sequence ID when seeding the sequence. Defaults to true.
      • When false, it means all sequences evaluate to the same regardless of which name they have.
  • /random (value|roll) notes:
    • When using roll rather than value, the resulting value is also shown in chat for all players.
    • When sequence not specified, this command can be executed by players without operator privileges.
  • /random reset notes:
    • By default, all sequences are seeded as 0, true, true.
    • Using * instead of a sequence ID resets all sequences and sets the default parameters.
    • If no seed is specified, the sequence resets to the default parameters.

Attributes

• Added the generic.max_absorption attribute.
  • Acts similar to generic.max_health, but instead of being the upper bound for Health, it is the upper bound for AbsorptionAmount.
  • The mob effect absorption increases generic.max_absorption as well as fills the AbsorptionAmount to the max when applied.

Experiments

• Added the "Villager Trade Rebalance" experimental toggle (trade_rebalance data pack).

Tags

• Added the following block tags:
  • #camel_sand_step_sound_blocks: contains #sand and #concrete_powder.
  • #concrete_powder: contains all types of concrete powder.
• Added the following damage type tag:
  • #no_knockback: contains explosion, player_explosion, and bad_respawn_point.
    • Causes knockback to not be caused by the damage itself. Used in vanilla for damage that is caused by events, such as explosions, which apply knockback separately.
• Added the following entity tag:
  • #non_controlling_rider: contains slime and magma_cube.
    • Represents entities that don't override their vehicles movement control.

Barrier

• No longer produces fall particles when entities fall on it.
• No longer creates particles when a player brushes it.
• Can now be waterlogged by players in Creative mode.
  • Water cannot be placed in them or taken out by non-direct interactions such as dispensers.

Chorus flower

• No longer provides support for hanging or standing blocks.

Decorated pots

• Now have Creative inventory tooltips.

Enchanting table

• Reverted the texture of lapis lazuli slot to the texture before 1.18-pre5, to make the consistency with smithing table.

Pink petals

• The size of the hitbox now increases with the number of petals.

Sculk sensor and calibrated sculk sensor

• Can now detect the following events:
  • entity_action (new), with frequency 4:
    • Camels dashing.
    • Camels standing up.
    • Camels sitting down.
    • Turtles clearing away sand.
    • Witches drinking a potion.
  • entity_damage, with frequency 7:
    • Totems of undying activating.

Smithing table

• Now in the custom recipes, the upgrade material can be sent to the GUI instantly with the + left click shortcut.

Music discs

• The Pigstep music disc is now the last one of the music discs in the Creative inventory.

Camels, frogs, goats, and sniffers

• Now panic when damaged while attached to leads.

Villagers

• The discount for curing a villager is no longer multiplied if the villager is reinfected and cured again.
• Now attempt to spawn an iron golem every 30 seconds instead of 35.

Display entities

• Now start updating their client-side position and rotation on the first tick after an update.
  • In previous versions, updates were applied in the same tick, causing uneven motion.
  • New behavior is now similar to armor stands, mobs and players.
• On the server, position and rotation are still updated immediately.
• Duration of this interpolation is controlled by the field teleport_duration.
  • 0 means that updates are applied immediately.
  • 1 means that the display entity moves from current position to the updated one over one tick.
  • Higher values spread the movement over multiple ticks.
  • Please note that this value is clamped to avoid glitches due to periodic position updates.
  • The new value applies only to position and rotation changes made after it changed.
    • That means any current movement continues unchanged.
• Note: behavior while riding remains unchanged from previous versions.

Ore distribution

• Diamond ore is now generated more frequently in the deepslate layers of the Overworld.
  • Added a new ore blob placement: Uniform distributed, from height -64 to -4, with blob size 8, generation frequency 2 and a 50% chance of discarding when exposed to air.
  • Other existing diamond ore placements remain untouched.

Functions

• A single backslash \ as the last non-whitespace character of a line now allows a command to be continued on the next line.
  • Leading and trailing whitespace of the following line are stripped before appending.
• Functions can now contain macro lines, making them Function Macros.
  • Any line beginning with $ (as the first non-space character) marks a macro line.
  • A macro line also contains one or more substitutions in the form of $(variable).
    • Commands with variable substitutions are re-evaulated after substitution.
      • Running commands with this type have extra cost compared to pre-parsed functions.
      • Game attempts to cache the result of certain parameter set being used in a call, to reduce costs when repeatedly calling.
  • When calling a function macro a compound with data for all argument variables must be provided.

/execute

• Added (if|unless) function subcommand.
  • A new execute sub-command that runs a function or function tag and matches the return value(s). If a tag is given, all functions run regardless of the results of prior functions.
  • Syntax: /execute (if|unless) function <function> -> [execute]
  • Arguments:
    • function: The function or tag to run.
  • The matching of the result value of the function(s) that run:
    • At least one of the functions must succeeed for the match to succeed.
    • A successful call is defined as a function that:
      • Uses the return command to return a value.
      • The return value is not 0.

/function

• Extended command usage, now supported parameters for function macro's variable substitution.
  • New syntax: /function <name> [<arguments>|with (block <sourcePos>|entity <source>|storage <source>) [<path>]]
  • New arguments:
    • arguments: A data compound, enclosed in {}.
    • Data source: A data source specification, like what could already be used for /data get.
    • path: An NBT path specification.
  • The data source and path must specify a compound data entry.
  • The compound must contain one entry for each variable used in the macro.
  • More data may be present in the compound and if so is ignored.
  • Calling a non-macro function with a data compound is silently ignored.
  • When a macro is called, the values provided are substituted in place of the variable specifications and the resulting commands are executed.
    • In order to improve performance when repeatedly calling with the same parameter, values in the provided compound which are referenced in macro as parameters are cached.
  • Any syntax errors in the lines resulting from variable substitution result in the entire function call being skipped.

/item

• Can now replace items in jukeboxes.
• Can now remove items in chiseled bookshelves.

/return

• Added run subcommand: /return run <command>.
  • This takes the result value from running the specified command and returns that as the return value of the function. In all other aspects, it works like return with a specified return value. If the given command fails, the return value is 0.

General

• History of used commands is now saved and accessible across worlds.
  • The last 50 commands that are sent in chat are remembered across game sessions.
  • The command and chat history can be accessed by pressing or in the chat.
  • Regular chat is only persisted within the same game session (leaving a server or world clears them).
  • Recent commands are stored in command_history.txt in the .minecraft folder.

Advancements

• The "Smithing with Style" advancement now grants 150 experience upon completion.

Recipe books

• Bamboo fence and bamboo fence gate are now grouped with the other ones.

Chunk tick

• randomTickSpeed game rule now affects the rate of accumulation of snow and ice the same way it affects crops and other blocks.

Data pack

• The pack format version is now 16.

Debug screen

• Values in the SH row now show up as question marks when playing on a server, instead of wrong values.
• When hitboxes are displayed through  + , entities that have a passenger display the passenger's attachment point.

Game events

• Added entity_action game event, to replace entity_roar and entity_shake.

"Multiplayer" and "World Selection" screens

• Renamed "Cancel" button to "Back".

Pack metadata

• New features have been added to data packs and resource packs to allow creation of packs that are compatible with multiple versions of the game.
  • Pack metadata now includes an optional field supported_formats which describes a range for pack formats that this pack supports.
    • Examples: 16, [16,17], {"min_inclusive": 16, "max_inclusive": 17}.
  • pack_format field is still required and its format remains unchanged, to allow older game versions to read pack data.
    • If supported_formats is present, it must contain the value declared in pack_format.
    • Since this new information is ignored by older versions of the game, they will always see a "normal", single-version pack, without any extended compatibility.
• Packs can now contain overlay directories ("overlays").
  • Overlays are sub-packs applied over the "normal" contents of a pack.
    • These directories have the same layout as the top-level pack, including the assets and data directories.
    • Overlays can be applied if they support the client's pack format.
    • Overlays can add and replace files, but not remove them.
      • For example, if the overlay foo is applied, the file foo/assets/minecraft/textures/bar.png replaces contents of assets/minecraft/textures/bar.png.
    • pack.mcmeta and pack.png are ignored in overlay directories.
  • New section called overlays have been added to pack metadata.
    • It contains an entries field, containing a list of overlays.
    • Every overlay entry has two fields:
      • formats - range of supported formats.
      • directory - overlay directory (allowed characters: a-z, 0-9, _, and -).
  • Order of application: overlays are stacked from the bottom to top of the list.
    • For example, if a pack has two overlays: "entries": [{"directory":"A", ...}, {"directory":"B", ...}], the game first looks in B, then A and then in the top pack directory.

Protocol

• Optimized the way chunks are sent to clients to allow players with low-bandwidth internet connections to play on multiplayer servers.
  • Chunks are no longer sent over the network to the client in one big continuous batch.
  • They are instead sent in smaller batches depending on the available bandwidth. This means that:
    • Clients with extremely low-bandwidth connections don't time out while loading the world.
    • Clients with low-bandwidth connections can interact with the world while some chunks are still loading.
  • Only chunks within the client's render distance are now sent.
• Changed network protocol to allow for more data-driven content in the future.
  • Configuration phase automatically starts after login phase (i.e. after client account has been verified) and lasts until the player joins the world (play phase).
  • Clients can stay in configuration phase indefinitely - it's up to server to release it to the world.
  • Servers can also request clients to re-enter the configuration phase after it has entered the play phase.
    • Other players see such clients as disconnected.
  • Users in configuration phase aren't visible on the player list.
  • Actions allowed in configuration phase (moved from play phase).
    • Configuration of data-driven registries.
    • Configuration of enabled features.
  • Actions shared between configuration and play phases:
    • Application of server resource packs.
    • Update of tags.
    • Exchange of custom packets.
    • Ping and keep-alive packets.
  • The server now negotiates resource pack in the configuration phase.
    • This means that the player no longer is in world when answering prompts and reloading resources.

Resource pack

• The pack format version is now 16.
  • The process of upgrading a pack can be assisted by using an automated Slicer tool.^[2]
  • All textures containing multiple sprites in a sheet for GUI have been split into individual sprites under textures/gui/sprites (automated by Slicer tool).
  • All textures in the realms namespace have been moved into the minecraft namespace (automated by Slicer tool).
  • villager2.png has been renamed to villager.png (automated by Slicer tool).
  • icon/trial_available and realm_status/expires_soon GUI sprites are animated with .mcmeta declarations instead of individual sprites (automated by Slicer tool).
  • The bundle tooltip background is now drawn as a nine-sliced sprite.
  • The icons for the Accessibility, Language, Realms News buttons have been split from their underlying button texture.
  • The Realms Invite button is now drawn as an overlay on the normal button texture.
    • The highlighted texture state for this button has been removed.
  • The highlighted states for Realms invitation number icons have been removed.
  • The exclamation marks on the notification\more.png have been removed.

Scoreboard

• The belowName display slot selector is now below_name.

server.properties

• Added new log-ips option (defaults to true).
  • When set to false, prevents player IPs from being included in the log when players join the game.

Tags

• Moved all types of concrete powder to newly added block tag #concrete_powder from #mineable/shovel block tag, then added #concrete_powder to #mineable/shovel.
• Removed entity_roar and entity_shake from #vibrations and #warden_can_listen game event tags, then added entity_action to them.

Telemetry

• Added a button to the telemetry data collection screen that links to the Microsoft Privacy Statement.

General

• Added validation for symbolic links in data packs and resource packs, to improve safety.
  • This feature expands on symbolic link validation in worlds added in the previous release.
  • The game now warn users if a pack added via drag and drop contains disallowed symbolic links.
  • Packs containing disallowed symbolic links aren't visible in UI and commands.
  • Additionally, directories and files that are not recognized as packs no longer are copied via drag and drop.

These changes only take effect when the "Villager Trade Rebalance" experimental data pack is enabled.

Trading

• Changed the trading mechanism of librarians selling enchanted books.
  • Instead of offering every possible enchanted book, librarians are now offering specific enchanted books depending on which biome they come from.
    • Jungle and swamp villages do not generate naturally. Thus, players must breed villagers or cure zombie villagers in these biomes to access their trades.
  • All tradable enchanted books now split to special books and normal books.
    • Special books have a specific enchantment with a fixed level, and are only available from master librarians with full XP.
    • Normal books have a specific enchantment without a fixed level, just like before.
  • All enchantments used for crossbow, fishing rod, and trident are removed from trading.

Available tradable enchantments

Category	Desert	Plains	Savanna	Snow	Taiga	Jungle	Swamp
Special	Efficiency III	Protection III	Sharpness III	Silk Touch	Fortune II	Unbreaking II	Mending

• Changed the wandering trader trades.
  • Trade list now made up by following trades, in order:
    • Buying trade (new) × 2
    • Special selling trade × 2
    • Ordinary selling trade × 5
  • Added new buying trades, some selling trades, and changed some existing selling trades:
