Minecraft 1.20.5 Snapshot 23W03B Patch Notes

The New Year’s snapshot has arrived, and with it, new Breeze buffs to try! So, today, we explore Minecraft 1.20.5 Snapshot 23W03B, the Armadillo changes it brings, and how to hop into Minecraft 1.21 before the patch officially releases late this spring.

Patch Notes

New Features


Armadillo visual update! We gathered feedback from the first Armadillo snapshot, and the next step in the look of the Armadillo, the Armadillo Scutes and the Wolf Armor are now here.

  • Armadillos now also spawn in Badlands

Armadillo Rolling Up Behavior

  • Spiders and Cave Spiders will run away from Armadillos not in a rolled up state
  • Adjusted the texture of the Wolf Collar layer to be more consistent with the new Wolf Armor


  • The default focus is now always set when entering or exiting any menu while navigating using tab or arrow keys
Technical Changes
  • The Data Pack version is now 28
  • The Resource Pack version is now 24
  • Custom Villager trades can be configured to accept items that have different tags from the expected item byadding ignoreTags: true in the trade’s NBT
  • When entities leave or enter the end the area they arrive in will now stay loaded for 15 seconds, matching the behavior of nether portals
  • Added transfer packets
  • Added cookie packets
  • Decreased the default size of the spawn chunks and made the value configurable

Transfer Packets

  • Custom servers can now request that clients connect to another server with a new packet
  • When a client is transferred it will connect to the target server with a new transfer intent (id 3)
  • By default servers will not accept incoming transfers and will disconnect the client
  • This can be changed by setting the accepts-transfers property to true in the file
  • Resource packs are maintained across transfers
  • In the case of a transfer custom servers can skip authentication with a new flag

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

Spawn Chunk Changes

  • The size of the spawn chunks changed from radius 10 (19×19 entity ticking chunks) to radius 2 (3×3 entity ticking chunks)
    • This was done to reduce memory usage, loading times and CPU usage
    • We opted to not fully remove spawn chunks to allow players who currently utilize this functionality to continue to do so
  • Added a new gamerule spawnChunkRadius to set the size of the spawn chunks
    • Possible values are 0 to 32, where 0 completely disables the spawn chunks and 10 is equivalent to the functionality before this change
    • Default value is 2, equivalent to 3×3 entity ticking chunks
Data Pack Version 28
  • The minecraft:sweeping enchantment has been renamed to minecraft:sweeping_edge
  • Added Advancement Criteria trigger default_block_use which triggers due to the default interaction of a block by a player, such as opening a door
  • Added Advancement Criteria trigger any_block_use which triggers due to any type of interaction with a block by a player, such as using an item on the block or its default usage


Item Tags

New item tags controlling what enchantments can be added to what gear:

  • minecraft:enchantable/foot_armor
  • minecraft:enchantable/leg_armor
  • minecraft:enchantable/chest_armor
  • minecraft:enchantable/head_armor
  • minecraft:enchantable/armor
  • minecraft:enchantable/weapon
  • minecraft:enchantable/sword
  • minecraft:enchantable/mining
  • minecraft:enchantable/mining_loot
  • minecraft:enchantable/fishing

  • minecraft:enchantable/durability
  • minecraft:enchantable/bow
  • minecraft:enchantable/equippable
  • minecraft:enchantable/crossbow
  • minecraft:enchantable/vanishing

Entity Type Tags:

  • Added minecraft:ignores_poison_and_regen for entities that cannot be affected by Poison and Regeneration effects
  • Added minecraft:illager_friends for entities that Illagers will consider allies (unless on a different team)
  • Added minecraft:inverted_healing_and_harm for entities that have inverted meanings of the Healing and Harm effects
  • Added minecraft:not_scary_for_pufferfish for entities that will not cause Pufferfish to puff
  • Added minecraft:sensitive_to_bane_of_arthropods for entities sensitive to Bane of Arthropods
  • Added minecraft:sensitive_to_impaling for entities sensitive to Impaling
  • Added minecraft:wither_friends for entities that the Wither will not target and which cannot harm the Wither
Resource Pack 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
Experimental Features


  • Breeze now deflects all projectiles
  • Deflected projectiles now deflect in the direction of the shooter

How to Install Minecraft 1.20.5 Snapshot 23W03B

Installing Minecraft 1.20.5 Snapshot 23W03B on Java Edition begins right inside the Minecraft client. First, open the Minecraft Launcher and enable snapshots in the “Installations” tab. Second, click “New Installation.” And third, select “Latest Snapshot” in the drop-down menu before finally clicking “Create.” The new snapshot installation will now be a selectable option before clicking play.

However, the experimental features in Minecraft 1.20.2 require some extra steps once in-game. Select “Create New World” and then “Experimental.” This should bring up a list of optional features that can be enabled. Once the desired settings are selected, head back out and click “Create New World” again. With the new world made, all that’s left is to select it and click play!

Please note snapshots can corrupt old worlds! Ensure backups have been taken.

Minecraft 1.20.5 Snapshot 23W03B Patch Notes

Patches in between major updates don’t usually include additions as exciting as Armadillos! Maybe Minecraft 1.21 has so many unannounced features that Mojang felt it necessary to split up the releases. What do you think was their reason?

Until Next Time,
