Minecraft: Java Edition is jumping on the Wild Update train! The first snapshot for 1.19 is now available. It contains frogs, the Deep Dark, and a bunch of new blocks. We've also entered the era of 3D directional audio. Keeping up with the times!

Happy mining!

New Features in 22w11a

Added the Deep Dark biome
Added Frogs & Tadpoles
Added mangrove blocks
Added mud and mud brick blocks
Added Sculk, Sculk Veins, Sculk Shrieker and Sculk Catalyst blocks
Added 3D Directional Audio option

Deep Dark

Dig into the depths far underground to uncover the darkest biome in Minecraft - the Deep Dark.

Dimly lit and eerie, the Deep Dark is sure to strike fear into the hearts of even the most brave player
The floor of the Deep Dark is covered in sculk
No mobs spawn in the Deep Dark

Frog

Frogs can jump
Frogs can swim
Frogs can walk on land
Frogs can croak
Frogs can eat small slimes, causing a slime ball to drop
Frogs can eat small Magma Cubes, causing a Froglight block to drop
Each Frog variant drops a specific Froglight Block
Three Froglight blocks are added, a lightsource block

Tadpoles

Tadpoles can swim in water
Tadpoles on land "jump around" like fishes on land, and eventually dies
Tadpoles that grows up turns into a Frog
Tadpoles grow into a different type of frog based on the biome they are born in (Cold, Temperate, Warm)
Tadpoles can be caught in a bucket

Mangrove wood blocks

Added a new type of wood: Mangrove! Mangrove biome + mangrove trees are coming in a later snapshot.

Mangrove log and stripped mangrove log
Mangrove wood and stripped mangrove wood
Mangrove roots and muddy mangrove roots
Mangrove boat, button, pressure plate, door, trapdoor, sign, slab, fence, fence gate, and stairs

Mangrove leaves and propagules

Mangrove propagule is a sapling that grows from the bottom of mangrove leaves
Bonemealing mangrove leaves will cause a new propagule to start growing beneath it
Propagules grow through 4 stages, and growth can be accelerated by bonemealing
You can break off a fully grown propagule and plant it like a sapling. For now it will grow in an oak tree, but will of course grow into a mangrove tree when that is done.

Mud

Mud is a block that will generate in the upcoming Mangrove biome.
When walking on mud, entities sink down a bit. Like soul sand, but without the slowdown.
Mud can be created by using a water bottle on dirt, by hand or with a dispenser.
Packed mud can be crafted from mud

Mud bricks

Mud bricks are a building block that can be crafted from packed mud
Mud bricks can be crafted into Mud brick stairs, walls, and slabs using a crafting table or stonecutter.

Sculk

The rattling tendrils of the Sculk Sensors had to come from somewhere, right? Introducing Sculk, a new family of blocks that dwells in the Deep Dark.

Added Sculk Catalyst block, a mysteriously soul-emitting block that blooms with Sculk patches underneath nearby dying mobs
- Mobs that perish in the presence of the catalyst will not drop their experience
Added Sculk blocks
- When a mob dies near a Sculk Catalyst, some unknown process seems to consume blocks beneath and turn them into Sculk blocks
- Sculk charge when spreading will have a chance to grow certain blocks, like Sculk Sensors on top of it, consuming its charge.
Added Sculk Vein blocks
- These veins are found on the edge of Sculk patches
- Similar to Glow Lichen, they can be placed in any orientation
- Spreading of veins causes other blocks to be taken over by the sculk
- Sculk Vein can spread underwater
Added Sculk Shrieker block.
- Sculk Shriekers can be found growing rarely from the charge of a Sculk Catalyst
- Sculk Shrieker can be waterlogged
- Sculk Shrieker requires Silk Touch to obtain otherwise drops experience when mined
Souls from mobs will spread through Sculk Veins and Sculk Blocks in random directions until

they find a valid substrate they can feed of off - The charge from souls in the Sculk Blocks and Sculk Veins will eventually decay, but it will decay much, much slower in the close vicinity of the Sculk Catalyst, and much faster away from its host - If the charge is dropped outside the range of the Catalyst, it has a chance of growing a Sculk Sensor

Sculk, Sculk Veins and Sculk Catalysts require Silk Touch to acquire. Otherwise, they drop experience when mined
The efficient tool for all Sculk family blocks is the Hoe

3D Directional Audio

Added sound option for 3D Directional Audio simulation
This option is best experienced with headphones

Technical Changes in 22w11a

The data pack format is now 10
The resource pack format is now 9
Added 3D Blending
Added new font glyph provider for spaces
Added estimated GPU utilization percentage to performance profiling metrics and F3 debug screen
- This is only available for graphics devices that support GPU timer queries
Added ability for data and resource packs to selectively hide files from packs below them
World presets/types and flat world presets in "Create World" screen can now be controlled by datapacks
Added server property max-chained-neighbor-updates to limit the amount of consecutive neighbor updates before skipping additional ones. Negative values remove the limit.

Blending

Blending now support 3d biome blending, so it will blend the underground biomes as well.
Removed blending_data.old_noise, now existence of blending_data in chunk data determines if a chunk is considered old
Added blending_data.min_section and blending_data.max_section that determines which sections will be used for data for blending

Space glyph provider

New glyph provider type space is added 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 not longer hardcoded (needs to be declared manually in font)

Pack filters

Data and resource packs can have filter section in pack.mcmeta.
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 will be filtered out (i.e. treated as if it wasn't 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 omited. Missing field matches every value.
For example, adding pack with this section in pack.mcmeta after vanilla pack will hide all recipes and advancements defined by vanilla pack

"filter": {
    "block": [
        {
            "namespace": "minecraft",
            "path": "recipes/.*"
        },
        {
            "namespace": "minecraft",
            "path": "advancements/.*"
        }
    ]
}

World presets

New registry types worldgen/world_preset and worldgen/flat_level_generator_preset were added to data-drive presents (like "Amplified" or "Single Biome")
Two tags for world presets added (normal and alternative) to control values show on "World Type" button in "Create World" screen
One tag added for flat world presents (visible) to control order of elements displayed in "Configure Flat World" screen
World presets can also be used as a value of level-type in server.properties

Predicates

The feature field in location predicates is now called structure
