Java Edition 24w05a

24w05a is the sixth snapshot for Java Edition 1.20.5, released on January 31, 2024^[1] which adds the vault and fixes bugs.

Particles

• Added vault_connection particle, which shows up when near a vault.

Server

• Added a reserved region file compression id for third-party servers to use for custom compression implementations.
  • Compression id 127 can now be used for custom implementations of region file compression.
  • When used, the version id must be followed by a namespaced string representing the custom algorithm used.
• Added an option to not compress region files.
  • Added a third value to the dedicated server configuration property region-file-compression: none does not compress the data.
  • Consumes significantly more space and requires significant time to read and write, even though CPU is used less.
  • Might make sense together with filesystem level compression.
• Allowed server operators to view dedicated server TPS debug chart.

Tags

• Added the #dyeable item tag: contains leather_helmet, leather_chestplate, leather_leggings, leather_boots, and leather_horse_armor.

Horse

• Replaced [NBT Compound / JSON Object] ArmorItem tag with [NBT Compound / JSON Object] body_armor_item.

Llama

• Replaced [NBT Compound / JSON Object] DecorItem tag with [NBT Compound / JSON Object] body_armor_item.

Wolf

• Replaced [Byte] armor tag with [NBT Compound / JSON Object] body_armor_item.

Slots

• Replaced horse.armor slot argument with armor.body, applicable now to all mobs.

Data pack

• The pack format version is now 30.
• Added [NBT Compound / JSON Object] body_armor_item to entity data, which functions similarly to entries of [NBT List / JSON Array] HandItems and [NBT List / JSON Array] ArmorItems.
  • Also added [Float] body_armor_drop_chance, which determines the chance of dropping body armor.
• Potion effects stored in items or entities no longer encode their default values.
  • amplifier: 0
  • duration: 0
  • ambient: false
  • show_particles: true

Resource pack

• The pack format version is now 25.
• The unused attributes array in core shader definitions has been removed.
• The IViewRotMat uniform has been removed, and the Position attribute for entities is now in (camera relative) world space.
• Light direction uniforms are no longer premultiplied by the view matrix.
• Added texture and model files for vault block.
• Changed texture for the trial key item.
• Added texture and particle file for vault_connection particle.

Shaders

• Removed position_color_normal and position_tex_lightmap_color shaders.
• Replaced position_tex_color_normal shader with rendertype_clouds.

These additions and changes only take effect when the Update 1.21 experimental data pack is enabled.

Vault

• A block that holds locked treasure and loot - find the right key to eject its rewards.
  • Found throughout trial chambers, containing the structures' most valuable loot.
  • Vaults in trial chambers require a trial key to be unlocked.
  • When activated with a trial key, it ejects rewards.
• Can be unlocked by an unlimited amount of players.
  • It can be only activated once per player. After a player has unlocked a vault, they cannot unlock that vault again.
  • If a player has not unlocked that vault before, an orange stream of particles flows from the player to the vault when nearby.
• Has a keyhole that is open or closed depending on the players nearby.
  • If any nearby player has not unlocked that vault, the keyhole is open.
  • If all nearby players have unlocked that vault, the keyhole is closed.
• Within its cage, it cycles through and displays items which are possible to eject from its loot table.
• The rewards it ejects are randomized from its loot table each time it is unlocked.
• Cannot be crafted or obtained in Survival, and does not drop anything when mined.
• Explosion-resistant and cannot be moved.
• Vaults currently reuse the same loot table that reward chests previously used in the trial chambers.

Trial key

• Can now be used to open vaults.
• Texture changed to match the vaults.

Tags

• Added vault to the #features_cannot_replace block tag.
