Java Edition 1.20/Development versions

A type of sculk sensor which does not generate naturally and allows players to filter vibrations based on their frequency level.
Can only be crafted with one sculk sensor and three amethyst shards in the crafting table.
One side of the calibrated sculk sensor can receive a redstone signal as an input.
Emits light level of 1
- The strength of that redstone signal is the only vibration frequency the calibrated sculk sensor listens to.

Pitcher plant

A type of plant which grows from the pitcher pod after 4 stages (5 stages in total).
Can be obtained by breaking a fully grown pitcher crop.
Can be crafted into a cyan dye.
Cannot be placed in a flower pot.

Sniffer egg

Can be found in the suspicious sand generated in warm ocean ruins.
Also dropped when two sniffers breed.
Hatches into a snifflet.
- When placed on a moss block, it hatches after approximately 10 minutes.
- On all other blocks, it hatches in approximately 20 minutes.

Suspicious gravel

The suspicious gravel looks rougher than the gravel block.
Affected by gravity and vanishes when landing.
Drops nothing when mined or moved, even if mining with Silk Touch.
Generates naturally in cold ocean ruins.
Brushing the suspicious gravel with a brush extracts objects.
- Has four stages of extracting and recovers gradually when stop brushing.
- Turns to regular gravel when the extraction is done.
- Only suspicious gravels with a valid archaeological loot table (the ones naturally generated) can extract an item.

Items

Pitcher pod

Can be planted on farmland and grows into a pitcher plant.
Can only be obtained if a sniffer digs up a pitcher pod.
Drops pitcher plant when fully grown, otherwise drops itself.

- Desert pyramid
  - Miner
- Desert well
  - Brewer
- Ocean ruins (cold)
  - Blade

- Ancient city: they can be obtained randomly from chests generated in these structures accordingly, and are duplicated using a cobbled deepslate block.
  - Silence armor trim
    - This is the hardest one to get, with only an 1.25% chance per chest.^[2]

World generation

Trail ruins

A buried generated structure from a lost culture.
Generates in taigas, snowy taigas, old growth taigas (both types), old growth birch forests, and jungles.
Comprised of a tower, a path across the bottom, and a few additional rooms attached to the side.
Contains suspicious sand and suspicious gravel, as well as mud bricks and several colors of terracotta and glazed terracotta.
Four armor trims and seven pottery shards can be found here.

Changes

Blocks

Block of amethyst

Added a new behavior called "vibration resonance" when it is placed adjacent to sculk sensors.
- If that sculk sensor receives a vibration, the block of amethyst re-emits its frequency as a separate vibration at its location.

Added a new property named cracked.
- Is used to determine the sounds the block use upon breaking.

Sculk sensor

Vibration frequencies of many actions in the game have been tweaked and greatly simplified to prevent unwanted interference, as following:

Action	Frequency value
Movement in any medium (land, water and air)	1
Landing on any surface (land or water)	2
Item interactions	3
Gliding with an elytra or unique mob actions (Ravager roar, Wolf shaking, etc)	4
Dismounting a mob or equipping gear	5
Mounting a mob or interacting with a mob	6
Mobs and players getting damaged	7
Consuming items (drinking and eating)	8
Blocks 'deactivating' (door close, chest close, button unpress, etc)	9
Blocks 'activating' (door open, chest open, button press, etc)	10
Blocks changing (cauldron water level rising, adding food to campfire, etc)	11
Blocks being destroyed	12
Blocks being placed	13
Mobs and players teleporting or spawning	14
Mobs and players dying or an explosion	15

Signs

Text can now be edited by interacting with it after being placed in the world.
- Previous dye and glow ink sac effects are kept after editing.
Both sides of the sign can now have separate text and colors.
- By default, a sign prompts the player to input the front side's text when placed.
- To apply text to the back-side, the player must walk to the other side and interact with that face to edit it.
Signs can now also be waxed with honeycomb, preventing any further edits to its text.
- Click commands on signs can only be invoked when the sign is waxed.
- If a sign with a click command is not waxed, interacting with it doesn't invoke the command and instead opens up the edit screen as usual.

Suspicious sand

Now generates naturally in warm ocean ruins.

Items

Potions

Wither effect particle colors have been adjusted to make them more distinguishable.
Potion of Slow Falling has had its color tweaked to make it more distinguishable from the potion of Invisibility.

Smithing templates

The dune armor trim now has a new pattern and smithing template icon.
The sentry armor trim now uses dune armor trim's old pattern and has a new icon to fit this pattern.
- The sentry armor trim's old pattern is now used by the new shaper armor trim.

World generation

Ocean ruins

Now include suspicious sand and suspicious gravel blocks.

Non-mob entities

Display

Previous values are now always discarded if interpolation_duration is 0.
Made sure that render properties are applied at the same time (so block_state is applied at the same time as transformation, i.e. at next tick after receiving update).
Entities are not rendered unless initial data is received. That means display entities might not show on the first tick.
- Due to how game handles updates, changes to entities made after summoning might be delivered to clients with later tick.

General

Data packs

The data pack version is now 13, accounting for sign data format changes.

Feature flags

Removed update_1_20 feature flag and built-in datapack.
- All features and changes from the "Update 1.20" experimental pack are now part of the game.

Game events

piston_contract game event has been removed in favor of block_deactivate.
piston_extend and dispense_fail game events have been removed in favor of block_activate.
Many game events have new vibration frequencies:

Game event	Frequency value
`step`, `swim`, and `flap`	1
`projectile_land`, `hit_ground`, and `splash`	2
`item_interact_finish`, `projectile_shoot`, and `instrument_play`	3
`entity_roar`, `entity_shake`, and `elytra_glide`	4
`entity_dismount` and `equip`	5
`entity_mount`, `entity_interact`, and `shear`	6
`entity_damage`	7
`drink` and `eat`	8
`container_close`, `block_close`, `block_deactivate`, and `block_detach`	9
`container_open`, `block_open`, `block_activate`, `block_attach`, `prime_fuse`, and `note_block_play`	10
`block_change`	11
`block_destroy` and `fluid_pickup`	12
`block_place` and `fluid_place`	13
`entity_place`, `lightning_strike`, and `teleport`	14
`entity_die` and `explode`	15

Sounds

Step sounds can now combine for blocks walked through and stepped on.
- Occurs for carpets, snow, nether sprouts as well as warped and crimson roots.
  - The top-most block the player is walking on is played as normal.
  - The block underneath is played at a lower volume and pitch.

Structure Post-processors

A capped post-processor has been added which can limit how many blocks a delegated post-processor randomly transform in a structure.
- This can be used to configure a structure piece to have an exact amount of specific blocks, instead of using random distribution.
- It has following required parameters:
  - delegate - A post-processor which performs the actual block transformation.
  - limit - Maximum amount of blocks that the delegated post-processor can transform.
    - The blocks inside a structure are all randomly passed to the delegated post-processor until it has transformed the limited amount.
    - Either constant or random number generator sampled during post-processing.
Previously a rule could specify an optional fixed output_nbt which would be added to the processed output block entity; this field has now been changed to reference a block_entity_modifier.
- Existing block_entity_modifiers are:
  - passthrough: Retains existing fields on the block entity.
    - This is the default if no block_entity_modifier is specified.
  - append_static: Similar to previous output_nbt this provides fixed fields to add to the block entity.
    - A minor change is that this modifier appends configured fields to the processed block instead of replacing existing fields.
  - clear: Removes any existing fields on the block entity.
  - append_loot: Appends a loot table and seed to the block entity through required parameter:
    - loot_table: Referenced loot table to add to block entity as LootTable field.
    - Field LootTableSeed is also added to the block entity using random seeded by block position.

Tags

Added the cherry grove to the is_overworld biome tag.
Added wayfinder_armor_trim_smithing_template, shaper_armor_trim_smithing_template, silence_armor_trim_smithing_template, raiser_armor_trim_smithing_template, and host_armor_trim_smithing_template to the #trim_templates item tag.

23w16a

23w16a is the fourth snapshot for Java Edition 1.20, released on April 20, 2023,^[5], which adds a new command and fixes bugs.

Additions

Command format

/return

A new command that can be used to control execution flow inside functions and change their return value. Effects:
- Skip remaining separate top-level commands in the currently executing function (if any).
- The result value of the function command that triggered the execution is changed from the number of commands executed to the value.
- The result value of the return command is also the value.
Syntax: /return <value>
- value: An integer return value.

Gameplay

Added recipe_crafted advancement trigger; triggered when crafting a recipe.
- Conditions:
  - recipe_id: The resource location of the recipe crafted.
  - ingredients: An array of predicates for the item stacks used in the recipe.
    - A single item stack can only be used to fulfill one predicate.
    - Each predicate needs to be fulfilled to trigger the advancement. This allows for seperation between recipes that have same identifier but use different ingredients.
    - This field is optional. When not provided, or left empty, only the recipe_id dictates the success of the trigger.

General

Splashes

Added splashes:
- This sand is sus
- Remember to brush your... ...teeth
- Has working bookshelves!
- Sniff sniff...
- Place hanging sign here

Tags

Added block tags:
- #maintains_farmland: contains pumpkin_stem, pumpkin, attached_pumpkin_stem, melon_stem, melon, attached_melon_stem, beetroots, carrots, potatoes, torchflower_crop, torchflower, pitcher_crop, and wheat
  - Blocks that don't cause farmland to be converted into dirt when placed on top of it.
Added item tags:
- #villager_plantable_seeds: contains wheat_seeds, potato, carrot, beetroot_seeds, torchflower_seeds, and pitcher_pod.

- For reference, order of transformations applied to model (starting from innermost) is item_transform, rotate Y 180, transformation field, entity orientation (billboard option + Rotation field + Pos field).

World generation

Trail ruins

Reworked and added more variants.
No longer generates with sand and suspicious sand.
Tweaked the amount of gravel, dirt, and suspicious gravel.
Split the archaeological loot tables for the suspicious gravel within the structure.

  - hex_file: Path to ZIP archive containing one or more *.hex files (files in archive with different extensions are ignored).
  - size_overrides: List of codepoint ranges that should have width different that auto-detected (based on empty space in glyph). Fields:
