Minecraft Snapshot 24w44a

We're back in the shipping room to serve you the first snapshot release for Minecraft: Java Edition 1.21.4! It's coming in hot with some new pale goodies in the form of Eyeblossoms and Resin, two new additions to the Pale Garden biome. You'll also find that leaves will now fall from the Pale Oak trees in said biome, something we hope will crank up the eerie atmosphere even further. In addition to that, this release is also bringing a collection of technical updates and bug fixes.

Happy mining!

New Features#

The winter_drop is no longer an experiment.

Added Eyeblossoms#

Eyeblossoms are new flowers that generate in the Pale Garden biome. Unique features:

• They exist in two variants: Closed and Open Eyeblossom
• Eyeblossoms transition between the two variants based on the time of day
  • During the night, Eyeblossoms will become Open
  • During the day, they will become Closed
  • In dimensions that do not have a day/night cycle, they will remain as-is
  • When transitioning, flowers will emit a particle effect
• Eyeblossoms planted on the ground will communicate with each other, helping each other to open or close
• Open Eyeblossoms have glowing eyes during the night
• Eyeblossoms can be obtained by bonemealing the grass in the Pale Garden biome
• Bees get poisoned when they touch Eyeblossoms
• Bees can be tempted by Eyeblossoms, but they get poisoned on player interaction instead of typical breeding/growing behaviour
• Suspicious Stew made from Eyeblossom will have Blindness or Nausea effect depending on the variant
• Gray or Orange Dye can be crafted from Closed and Open Eyeblossoms respectively
• Wandering Trader can sell Open Eyeblossoms

Added Resin Clump, Block of Resin, Resin Brick, and a family of Resin Bricks blocks#

• Attacking a Creaking will cause its Creaking Heart to exude 2 to 3 Resin Clumps
• Resin Clump spawns on the sides of Pale Oak Logs that are close, and are connected to the Creaking Heart
• Creaking Heart is on cooldown and cannot produce more Resin Clumps for 5 seconds after an attack
• Resin Clump can be used as a material for armor trimming
• Block of Resin is a storage block for Resin Clumps
• Resin Clumps can be smelted into Resin Brick items
• Resin Brick items can be crafted into Resin Bricks, Resin Brick Slabs, Resin Brick Stairs, Resin Brick Walls, and then Chiseled Resin Bricks
• Resin Clump and Resin Block does not require a tool and are mined instantly
• The proper tool for Resin Bricks family of blocks is a pickaxe
• Resin Clumps can be found in the Woodland Mansion chest loot

Changes#

• The panorama has been updated
• Sword is no longer efficient to break Moss Carpet. The proper tool for Moss Carpet remains the Hoe
• Bees are now withered on player interactions with Wither Roses instead of typical breeding/growing behavior

Required tools for drops#

Developer's Note: We made it so any block that drops when its support is broken will also drop when mined with any tool. It seemed unfair that breaking a block directly could destroy it if it was possible to obtain it with any tool just by breaking the block below!

• The following blocks that require support now always drop when broken with any tool: Bell, Lantern, Soul Lantern, all Copper Doors, Iron Door, Heavy Weighted Pressure Plate, Light Weighted Pressure Plate, Polished Blackstone Pressure Plate, and Stone Pressure Plate
• The Brewing Stand now drops when broken with any tool
• The Ender Chest now drops Obsidian when broken with an incorrect tool, instead of dropping nothing

Pale Garden#

• Pale Garden has no music and if a player enters the biome while music is playing, the music will fade out

Creaking Heart#

• Creaking Heart can be obtained by using a Silk Touch enchanted tool
• Creaking Heart can be crafted with a Resin Block and Pale Oak Logs
• Naturally placed Creaking Hearts drop 20-24 experience when broken by a player, with or without silk touch
• Breaking a Creaking Heart block will drop a 1-3 Resin Clumps, and it is affected by Fortune enchantment

Pale Oak Tree#

• Pale Oak Leaves have a chance to spawn leaf particles if exposed on the bottom side
• Player grown Pale Oak trees grow without any decorations
• Naturally generated Pale Oak trees have Pale Hanging Moss hanging from the foliage, Pale Moss patches on the ground, and Creaking Heart blocks can generate in them
• Wandering Trader can sell Pale Oak Saplings

Pale Moss Block#

• Wandering Trader can sell a Pale Moss Block

Pale Hanging Moss#

• Pale Hanging Moss breaks instantly when mined
• Pale Hanging Moss requires shears or silk touch tools to be obtained
• Wandering Trader can sell Pale Hanging Moss

Creaking mob#

• Creaking melee attacks deal 3 points of damage (1.5 hearts)
• Illagers are scared of Creaking and will run away from them

The following changes apply for naturally spawning Creaking:

• Creaking reacts only to damage caused by mobs and projectiles, by swaying in place
• Creaking ignores Cactus, Sweet Berry Bushes and Powder Snow damage and can now walk through/over them
• Creaking has a twitching animation
• Is fire-resistant
• Creaking Heart decides to remove or replace the connected Creaking when:
  • It turns day
  • The Creaking is too far away from the Creaking Heart
  • A player intersects with the Creaking for a few seconds
