Minecraft Snapshot 24w04a

A Minecraft Java Snapshot

Hello again! Here is another snapshot bringing you some Armadillo changes, experimental feature changes, and a bunch of technical changes.We have some server-side performance improvements and improved debug tools along with a new transfer command. Enjoy!

Changes

  • Armadillo now also rolls up when it detects a mob, or a player that has attacked it recently
  • When an Armadillo is in rolled up state, its shell will protect it, and reduce the damage dealt to it, even allowing it to fully resist weak attacks
  • Renamed "Allow cheats" to "Allow commands"

Technical Changes

  • The Data Pack version is now 29
  • Added an option to use a faster region file compression algorithm on dedicated servers
  • Introduced changes to optimizing worlds
  • Improved server TPS debug chart
  • Reduced time needed to generate explorer maps to buried treasures

Region file compression algorithm

  • Added a dedicated server configuration property region-file-compression with 2 possible values:
    • deflate, the default option. Uses the old algorithm
    • lz4 uses LZ4 algorithm, which requires less CPU time to compress and decompress but uses more disk space
  • Changing the compression algorithm will not automatically recompress the world
    • New or updated chunks will use the newly configured algorithm, but the old ones will stay in the previous format

World optimizing changes

  • Optimizing singleplayer worlds and running dedicated server with forceUpgrade now also upgrades contentsof entities and poi directories of the world
  • New recreateRegionFiles dedicated server startup parameter
    • It will trigger world optimization similar to forceUpgrade, but will also rewrite all the chunks independentlyof whether they have been upgraded
    • This will create fresh and defragmented region files
    • Using this parameter after changing the region-file-compression server property will recompress all region filesin the new format

Improved the server TPS debug chart

  • As before, it is accessible by pressing F3 + 2 in a Singleplayer world
  • The bottom dark red section of the chart displays the time spent during the main logic of the server tick. It isequivalent to the value diplayed in the old chart
  • The light brown section displays time spent on running scheduled tasks
  • The purple section displays time spent executing all other code during the tick
  • The top light green (or yellow or red depending on lag) section displays time spent idling, waiting for next tick
  • The min, avg, max aggregate values are based on the sum of the first 3 sections

Data Pack Version 29

  • Added the transfer command

transfer Command

New command that triggers a transfer of a player to another server. Only exists on dedicated servers.

Syntax:

transfer <hostname> [<port>] [<players>]

Parameters:

  • hostname: String describing the hostname of the server to connect to
  • port: Integer denoting the port number of the server to connect to - if omitted, 25565 is used
  • players: The players to transfer - if omitted, @s is used

Experimental Features

Breeze

  • Breeze is now aggressive toward Iron Golems in addition to players
  • Breeze no longer retaliates against attacks from the following mobs: Skeletons, Strays, Zombies, Husks, Spiders, Cave Spiders, Slimes
  • The above mobs will not retaliate when hurt by the Breeze's Wind Charge Projectile

Copper Grates

  • Stonecutting Copper Blocks into Copper Grates outputs 4 Copper Grates

Fixed bugs in Snapshot 24w04a

  • MC-232489 - Retrieving a plant from a flower pot ignores inventory contents
  • MC-266449 - Breeze doesn't attack or retaliate against mob on sight
  • MC-266707 - Trial spawners ignore custom_spawn_rules
  • MC-267925 - Retrieving an item from a flower pot while holding something causes the item to end up in your off hand
  • MC-267937 - Shooting a breeze with a piercing crossbow makes the game crash
  • MC-267938 - The world loading percentage value can get covered by the spawn chunk loading animation when the "spawnChunkRadius" gamerule is set to large values
  • MC-267941 - The end portal kills mobs at spawnChunkRadius 0
  • MC-267953 - No element is focused when opening the realms world backups menu using keyboard navigation
