24w03a is the third snapshot for Java Edition 1.20.5, released on January 17, 2024^[1] which adds the spawnChunkRadius game rule, changes the textures of armadillo-related features, and fixes bugs. This is the first snapshot released in 2024.

Advancements

• Added triggers:
  • default_block_use, triggered due to the default interaction of a block by a player, such as opening a door.
  • any_block_use, triggered due to any type of interaction with a block by a player, such as using an item on the block or its default usage.

Game rules

• Added spawnChunkRadius to set the size of the spawn chunks.
  • Defaults to 2, equivalent to 3×3 entity ticking chunks.
  • Possible values are 0 to 32, where 0 completely disables the spawn chunks and 10 is equivalent to the functionality before this change.

Servers

• Added transfer packets.
  • Custom servers can now request that clients connect to another server with a new packet.
  • When a client is transferred, it connects to the target server with a new transfer intent (id 3).
  • By default, servers don't accept incoming transfers and disconnect the client.
    • This can be changed by setting the accepts-transfers property to true in the server.properties file.
  • Resource packs are maintained across transfers.
  • In the case of a transfer, custom servers can skip authentication with a new flag.
• Added cookie packets.
  • Cookie packets allow custom servers to request and store data on a client.
    • Each cookie may be up to 5 KiB in size.
    • Cookies may be requested during login, configuration and play phases — but only stored during the configuration and play phases.
  • Cookies are persisted across server transfers but are not persisted when the player disconnects.
    • This allows servers to pass along information such as authentication or custom game data to the new server.

• Can now spawn in badlands biomes.

Cave spiders & spiders

• Are now scared of armadillos not in a rolled up state.

Wolves

• The texture of the collar layer was adjusted.

End portal

• When entities leave or enter the End, the area they arrive in now stays loaded for 15 seconds, matching the behavior of nether portals.

Spawn chunks

• The size of the spawn chunks changed from radius 10 (19x19 entity ticking chunks) to radius 2 (3×3 entity ticking chunks).
  • This was done to reduce memory usage, loading times and CPU usage.
  • The developers opted to not fully remove spawn chunks to allow players who currently utilize this functionality to continue to do so.

Accessibility

• The default focus is now always set when entering or exiting any menu while navigating using tab or arrow keys.

Attributes

• Renamed generic.block_interaction_range to player.block_interaction_range.
• Renamed generic.entity_interaction_range to player.entity_interaction_range.

Data pack

• The pack format version is now 28.
• The minecraft:sweeping enchantment has been renamed to minecraft:sweeping_edge.

NBT data

• Custom villager trades can be configured to accept items that have different tags from the expected item by adding ignoreTags: true in the trade's NBT.

Resource pack

• The pack format version is now 24.
• The ttf font provider transforms have been adjusted to have more reasonable defaults.
  • shift is no longer applied double, and now directly represents a number of pixels in the game UI.
  • The font EM square is fitted to size pixels in the game UI, instead of between the font ascender and font descender.
  • The font baseline is positioned consistently with the default font (7 pixels below line top).
  • This means that generally, any font with a size of 9 and no shift should look correct by default.

These additions and changes only take effect when the Update 1.21 experimental data pack is enabled, the exception to this is the change to villagers, which takes effect when the Villager Trade Rebalance experimental data pack is enabled.
