22w11a is the first snapshot for Java Edition 1.19, released on March 16, 2022,[1] which adds the first features of The Wild Update, pack filters, space glyph provider, 3D directional audio, new tags and fixes bugs.



  • Added froglights, with 3 variants: ochre, pearlescent and verdant.
  • Emit a light level of 15.
  • Dropped when frogs eat small magma cubes.
    • When eaten by temperate frogs, drop ochre froglight.
    • When eaten by cold frogs, drop verdant froglight.
    • When eaten by warm frogs, drop pearlescent froglight.
  • Non-solid blocks that can be placed on the surface of water.
  • Laid by frogs after mating.
  • Hatches tadpoles after some time.
  • Does not drop upon breaking, even with silk touch.
Mangrove leaves
  • A new type of leaves.
Mangrove log
  • A new type of log, as well as a stripped variant.
  • Can be used to craft mangrove woods and planks.
Mangrove planks
Mangrove propagule
  • A new type of sapling.
  • Can be grown by bonemealing the mangrove leaves, grows from the exposed bottom of it.
    • Propagules can also grow spontaneously from leaves, but only if they're naturally generated (not player placed leaves).
    • Have 4 stages to fully grown, can be accelerated by bonemealing.
  • Can break off a fully grown one, plant it to growing a mangrove tree (currently not added, generates an oak tree instead).
  • Can be planted underwater.
  • Can be placed in flower pots.
  • Bees can pollinate them.
  • Bees follow players holding them and can be bred with them.
Mangrove roots
  • A see-through block just like leaves, but can be waterlogged.
    • Water currently doesn't spread outward like with other waterlogged blocks.
  • Mining faster when using axes.
  • Unlike leaves, it does not break when moved by a piston.
    • If the roots are waterlogged, the water vanishes.
  • Can be powered.
Mangrove wood
  • A new type of wood, as well as a stripped variant.
  • Can be used to craft mangrove planks.
Mud bricks
Muddy mangrove roots
  • Can be crafted from 1 mud and 1 mangrove roots.
  • Unlike regular roots, they are an opaque block that can't be waterlogged.
  • Mining faster when using shovels.
Packed mud
  • Can be crafted from 1 mud and 1 wheat.
Sculk catalyst
  • Generates in the deep dark biome.
  • Emits soul particles after a mob dies within 8 blocks, and grows sculk related blocks.
    • Spreads sculk blocks to wherever a nearby mob dies. The amount it spreads depends on the amount of experience the mob is meant to drop.
      • Even if the mob doesn't drop experience as it wasn't killed by a player, the blocks would still spread based on the amount of experience it normally drops.
      • Experience does not drop in these cases.
    • The charge decays over time, faster the furthest away from the catalyst it moves.
      • If a charge decays more than 4 blocks away from the catalyst, it has a chance of creating either a sculk sensor (90%) or a sculk shrieker (10%).
      • If a charge decays more than 24 blocks away from the catalyst, it merely vanishes.
  • Drops only experience when broken without silk touch.
  • Emits a light level of 6.
  • Sculk Catalyst Bloom JE1 BE1.gif Blooms when activated.
  • Can spread sculk only on blocks in the sculk_replaceable tag.
Sculk shrieker
  • Generates in the deep dark biome.
  • Has two soul-shaped patterns in the center.
  • Drops only experience when broken without silk touch.
  • Currently doesn't do anything due to the warden not being in this snapshot.
Sculk vein
  • Generates in the deep dark biome on the edge of sculk patches.
  • Generates in a layer on top of blocks and can be placed in all directions, like glow lichen.
  • Has an animated texture.
  • Some have parts that are transparent, allowing the player to see the block it is on top of.
  • Can be waterlogged.
  • Drops nothing when broken without silk touch.


Bucket of tadpole
  • Added bucket of tadpole, can be obtained by catching a tadpole using a water bucket.
Mangrove boat
  • A new type of boat, crafted with mangrove planks.
Spawn egg
  • Added frog and tadpole spawn eggs.


  • Can croak, jump, swim, and slowly walk on land.
    • Are able to jump over 5 blocks.
    • Frogs are faster in water than on land.
    • Preferred to jump to lily pad and big dripleaf.
  • Have 10♥♥♥♥♥ health points.
  • Come in three variants: temperate, warm, and cold.
    • The temperate variant is orange, the warm variant is white, and the cold variant is green.
  • Eat small slimes, dropping slimeballs in the process.
  • Can be tempted and bred using slimeballs.
    • Lay eggs on water after mating.
  • Grow from tadpoles.
    • Variants depend on the temperature of the biome it turns from a tadpole to a frog in.
  • Jump around like fish when on land, and eventually die.
  • Grow up into frogs after 20 minutes in the world, which can be sped up using slimeballs.
    • Frog type dependent on which temperature a tadpole grows in.
  • Have 6♥♥♥ health points.
  • Are hunted down by axolotls.
  • Can be held in a water bucket.

World generation[]

Deep dark
  • New biome at the "deepest depths of the world".
  • Tends to generate under continental/mountainous areas, exclusively within the deepslate layer between Y=-1 and Y=-64.
    • Currently can extend above the deepslate layer, sometimes up to around Y=33.
  • The surface is covered in sculk and contains all sculk-related blocks.
  • With the exception of spawners, no mobs can spawn there, similar to mushroom fields.
Upgrading of old worlds
  • Now support 3D biome blending, so it blends the underground biomes as well.


Chunk format
  • Added blending_data.min_section, and blending_data.max_section that determines which sections are used for data for blending.
Data pack and resource pack
  • Can have filter section in pack.mcmeta now.
    • This section has mandatory field block, which is a list of patterns (regular expressions) for namespaces and paths.
    • If any of files in packs added before one with filter section matches any pattern inside block, it is filtered out (i.e. treated as if not present in the first place).
    • filter section does not apply to a pack containing it, only to packs loaded before it.
    • Both namespace and path can be omitted: if they are, the game works as if they had been specified as a ".*". Missing field matches every value. When they are included, these fields contain a regular expression pattern.
    • For example, adding pack with this section in pack.mcmeta after vanilla pack hides all recipes and advancements defined by vanilla pack:
"filter": {
    "block": [
            "namespace": "minecraft",
            "path": "recipes/.*"
            "namespace": "minecraft",
            "path": "advancements/.*"
  • World presets/types and super flat world presets in “Create World” screen can now be controlled by datapacks.
    • New registry types worldgen/world_preset, and worldgen/flat_level_generator_preset were added to data-drive presents (like "Amplified" or "Single Biome").
Debug screen and profiling
  • Added estimated GPU utilization percentage to performance profiling metrics and F3 debug screen.
    • This is available only for graphics devices that support GPU timer queries.
  • Added "Blending" row, above the "Noise Router" row.
  • Added new glyph provider type space, to allow creation of space-like glyphs.
    • New provider has single argument called advances which is map of codepoint to glyph advance (width).
    • Rendering of space glyph is no longer hardcoded (needs to be declared manually in font).
  • Added "Directional Audio" sound option, for 3D Directional Audio simulation.
    • Uses HRTF-based directional audio to improve the simulation of 3D sound, making it easier to distinguish which direction a sound comes from (including if it is above or below the player).
    • Requires HRTF compatible audio hardware.
    • This option is best experienced with headphones.
    • Toggled off by default.
  • Added three new particles: sculk_soul, sculk_charge_pops, and sculk_charge.
