A lush mangrove swamp biome with turquoise water flowing through it. In the water, there's a boat with a chest in it, and up in the treetops, there's a bee flying around.

Minecraft Snapshot 22w14a

A Minecraft Java Snapshot

Mangrove trees! Warm frogs! Mud blocks! More mangrove trees! Today, we’re happy to bring you the most mud-tastic Java snapshot to date! 

Sure, it might be our only mud-tastic snapshot to date – but the important thing is that our new biome, mangrove swamp, now is available for testing, along with nitty-gritty features like the recovery compass and other, more technical tidbits.


New Features in 22w14a

  • Added Clay renewability
  • Added Mangrove Trees
  • Added Mangrove Swamp biome
  • Added Echo Shard and Recovery Compass

Clay renewability

  • Placing Mud above a block that has Pointed Dripstone underneath will eventually turn the Mud Block into Clay

Mangrove trees

Introducing a new type of water-adapted tree that spawns propped up on roots

  • Have a chance of spawning a Bee Nest
  • Grows from Mangrove Propagules

Mangrove Swamp

Muddy! Murky! Magnificent! Welcome to the newest biome - the Mangrove Swamp

  • Located in warmer, more humid places where you’d normally find the Swamp biome in Minecraft
  • Here you can find Bees and Warm Frogs
  • The floor of this biome is coated with a thick layer of Mud, so be sure to pack your best boots
  • Have a nice boat ride under and around the larger-than-life roots of mangrove trees

Recovery Compass

A new Recovery Compass can be crafted with Echo Shards which can only be found and are unique to Ancient City chests

  • Unlike a normal Compass, the Recovery Compass will point to the last place you died
  • If you are not in the dimension you last died, or you haven’t died yet in your world, it will randomly spin
  • It can be crafted with 1 Compass surrounded by 8 Echo Shards, which can be found in Ancient Cities

Changes in 22w14a

  • The Warden will now get angry at ALL living mobs that bump into it, not just players

Technical Changes in 22w14a

  • CatType fields on enitites with type minecraft:cat have been replaced with variant, with numeric values being replaced with string ids (so, for example, 5 becomes minecraft:calico)
  • Some mutually exclusive tests in entity predicate (playerfishing_hooklightning_bolt and catType) have been collapsed to type_specific field
  • Added item_delivered_to_player advancement trigger
  • Added allay_drop_item_on_block advancement trigger


Entity predicate

  • playerfishing_hooklightning_bolt and catType fields have been replaced with type_specific
  • type_specific has field type (one of playerfishing_hooklightning_bolt or cat) and same fields as removed fields
  • Example:
  • Before:
 "lightning_bolt": {
   "blocks_set_on_fire": 0
  • After
  "type_specific": {
    "type": "lightning",
    "blocks_set_on_fire": 0
  • catType has been wrapped to match new format and now uses new cat variant names instead of texture names:
    • Before
     "catType": "minecraft:textures/entity/cat/british_shorthair.png"
  • After
 "type_specific": {
    "type": "cat",
    "variant": "minecraft:british"
  • New type_specific options:
    • frog has variant field matching frog variant (minecraft:warmminecraft:temperate or minecraft:cold)
    • slime applies for slimes and magma creams, has size field matching slime size (smallest is 1)


  • Removed field location from triggers location, slept_in_bed, hero_of_the_village and voluntary_exile - it was handled exactly the same as player.location

New triggers


  • Triggered when an allay delivers an item to a player
  • Conditions:
    • player - a player for which this trigger runs


  • Triggered when an allay drops an item on a block
  • Conditions:
    • player - a player for which this trigger runs
    • location - a predicate for the block that the item was dropped on
    • item - a predicate for the item that was dropped
