Java Edition 22w46a

22w46a is the fifth snapshot for Java Edition 1.19.3, released on November 16, 2022, which adds piglin head and the unique interactions between note blocks and heads in the built-in experimental datapack, command and new telemetry data screen, changes the telemetry and the mechanism of texture loading, and fixes bugs.

Command format

 * A new command to change biome entries for an area.
 * Because biomes are not stored per-block, affected positions may not match input precisely.
 * Syntax:
 * : One corner of the area to fill.
 * : The other corner of the area to fill.
 * : The biome to set.
 * : The biome to set.

General

 * Options
 * Added telemetry data collection screen.
 * Displays information about the type of data that is sent.
 * The level of data sent can be controlled between "Minimal" and "All".
 * "Minimal" sends only the required data.
 * "All" sends the required data, as well as optional data.
 * The default data level is "Minimal".

Mobs

 * Enderman, Skeleton and Wither Skeleton
 * Now only spawn at light level 7 and below in the Nether, instead of 11 and below, to nerf certain portal-based mob farms.
 * Blocks carried by endermen now use loot tables to generate drops when killed.

Gameplay

 * Creative Inventory
 * Reordered Redstone tab.
 * Added rails to the Tools & Utilities tab next to minecarts.

General

 * Logging
 * Every telemetry event sent from the client is now logged to disk.
 * Old log files are removed after 7 days.
 * These can be found under the logs/telemetry directory.
 * A shortcut to this directory is available via the "Open My Data" button on the telemetry data collection screen.


 * Resource pack
 * To improve loading performance, block and item textures are now loaded before they are processed by block and item models.
 * By default, textures not in the textures/item and textures/block directories will no longer be automatically recognized and will fail to load.
 * Can have configuration files now, located in the new atlases directory, that control which images are included in the atlases. That directory contains following JSON entries for configuring atlases:
 * : textures used by block and item models.
 * ,,  ,  ,  ,  : used to render some special-case models.
 * : textures used for effect icons in the UI.
 * : textures used for paintings.
 * : textures used for particles (referenced by the  field in files within the particles directory).
 * If multiple packs include those files, they are merged by their order within the pack (same as tags in data packs).
 * Inside these files is a JSON object with a single list called.
 * Every entry in  runs in during load, in order of definition, adding or removing new files to the texture list; to be later referenced by block models, particles, etc.
 * Types of sources:
 * : lists all files in a directory and its subdirectories, across all namespaces.
 * : directory in pack to be listed (relative to textures directory)
 * : string to be appended to the sprite name when loaded.
 * : adds a single file.
 * : location of a resource within the pack (relative to textures directory, implied  extension).
 * : sprite name (optional, defaults to ).
 * : removes sprites matching the given pattern.
 * , : patterns (regular expressions, regex) of ids to be removed (only works for entries already in the list), if omitted, any value will be matched.
 * : copies rectangular regions from other images.
 * : location of a resource within the pack (relative to textures directory, implied  extension)
 * , : used for determining the units used by regions.
 * : list of regions to copy from the source image.
 * : sprite name.
 * , : coordinates of the top-left corner of the region.
 * , : size of the region.
 * Values such as  are transformed to real image coordinates via dividing by their divisor, and then multiplying by the real image size.
 * Example:
 * If a pack has a file named assets/test/textures/fancy/iridium.png and source is, the texture will be available in models as.


 * Telemetry
 * Added  event, and removed client Java version from the   event.
 * They are required events.
 * Data includes game mode, client or server modded status and game version.
 * Can be used to calculate how long the world session has lasted (in seconds and ticks).
 * Data from  is sent when a world is launched, and data from   is sent when a world is shut down (quitting to title, disconnecting from a server).
 * Added 2 new optional events:
 * Data includes frame rates, rendering performance, memory usage, operating system, and the modded status of the client and server.
 * With game version, it can be used to compare the performance profile for new versions of Minecraft.
 * Data includes the total time in milliseconds for the world to load, whether this was a new world, as well as game version and platform details.
 * Can indicates what impacts load times when added new features or do larger technical changes.
 * Data includes the total time in milliseconds for the world to load, whether this was a new world, as well as game version and platform details.
 * Can indicates what impacts load times when added new features or do larger technical changes.


 * General
 * Translation files and pack.mcmeta are now including non-ASCII characters (encoded as UTF-8) directly instead of using escape sequences.

Command format

 * Can now be conditional on biomes.
 * Syntax:
 * Syntax:

Blocks

 * Piglin Head
 * Piglins will now drop their heads when killed by a charged creeper.
 * The piglin head will flap its ears when powered by redstone, or when worn by a player while walking.

Blocks

 * Block of Bamboo and Block of Stripped Bamboo
 * Changed their top textures.


 * Bamboo Planks
 * Changed its texture to match the same tiling pattern as other plank variants.


 * Chiseled Bookshelf
 * Books in chiseled bookshelves can be added or removed from any slot by targeting the specific slot.


 * Note Block
 * When placing a mob head on a note block, that note block will now play one of the ambient sounds of that mob when played by a player or powered by redstone.
