New year, new Snapshot - we're now releasing the third Snapshot of Minecraft 1.20.5. This time around, we're bringing some updates to the Armadillo, the Breeze, as well as accessibility improvements.

In addition to a big bundle of bug fixes, we're bringing some changes to how spawn chunks are handled.

The spawn chunks are an area of the Overworld located at the world spawn which are always loaded in memory. These are useful for some players but use more of your computer’s resources and make the game load and run more slowly. (You can read more about spawn chunks at the community wiki!)

In this snapshot we made the size of the spawn chunks configurable by adding a new gamerule: spawnChunkRadius. The new default setting is 2 (which creates a 48x48 block area). This is 98% smaller than the previous area and will result in a noticeable performance improvement for most players.

If you would like to keep your spawn chunks working like they did before, you can use the game rule to change the spawn chunk radius value to 10. This will make your spawn chunks work the same as they did before, but you will miss out on the performance gains.

We're interested in hearing your feedback on this change and how the new default setting affects you.

Let's talk about spawn chunks!

New Features

Armadillo

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

Changes

• Adjusted the texture of the Wolf Collar layer to be more consistent with the new Wolf Armor

Accessibility

• 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 by adding 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 server.properties 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 (19x19 entity ticking chunks) to radius 2 (3x3 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 3x3 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

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

• Deflected projectiles now deflect in the direction of the shooter

Trade Rebalance

• In the Trade Rebalance Experiment, Villagers who buy armor now ignore durability and can buy damaged armor
