A camel is standing next to a river looking at the sun setting behind a dune. In front of the camel, there's a post made out of bamboo blocks with a hanging sign on it that says "22w42a".

Minecraft Snapshot 22w42a

A Minecraft Java Snapshot

Hello there! We are now releasing the first snapshot for 1.19.3! You might have been thinking that this snapshot would be for 1.20, but times are changing. Going forward, we are taking a bit of a different approach to how we release minor and major versions for Minecraft: Java Edition. Essentially, we will be releasing minor versions more often. You can find out more details about this in a post over here.

In this snapshot, we’re introducing feature toggles, which you might have seen in a post we released yesterday. This means we can add a toggle for Update 1.20 with features such as the Camel, without committing to releasing them in version 1.19.3. This lets us have experimental features available for testing, while still being able to release updates with new functionality, changes, and improvements, without having to remove those features from the game first.

In this snapshot, you’ll be seeing the features that we talked about during Minecraft Live as experimental features, a few changes to chat, some technical changes and many bug fixes.

Happy mining!

New Features in 22w42a

  • Some experimental features are now available through built-in experimental datapacks
  • Bundles are now available as an experimental feature
  • Added a new “Panorama Scroll Speed” accessibility option

Experimental Features

  • Some experimental features now need to be enabled to appear in worlds
  • Such features are enabled by adding a built-in datapack when creating a world
  • Feature toggles are meant to hide unfinished or experimental features, to make sure your existing worlds remain unaffected
  • Worlds that are using experimental features will be marked as “Experimental” in world selection list
  • Experimental features cannot be toggled for existing worlds

Added Camel

Camels are now available when Update 1.20 experimental features are enabled.

  • Camels can be equipped with a saddle and ridden by two players
  • Camels spawn naturally in Desert Villages
  • Camels are tall
    • Most hostile mobs will not be able to reach you when you are on a Camel
    • They can walk over fences without a sweat
  • Camels are very graceful, but grumpy mobs
    • They randomly sit down
    • While sitting, it is difficult to convince them to move
  • Camels can either walk slowly or sprint quickly
  • They can also dash forward but will lose stamina for a while when doing so

Hanging Signs

Ever wanted to hang up your signs? Fetch a few chains, strip some logs, and now you can! Hanging signs are now available when Update 1.20 experimental features are enabled.

  • Hanging Signs are a more expensive version of normal Signs
    • Crafted with 2 chains and 6 stripped logs of your preferred wood type
    • Crafting results in 6 Hanging Signs
  • Can be hung up in the following ways:
    • Underneath a block that can provide support in the center, like a full block or a fence
    • Attached to the solid side of a block
    • Attached to the side or underneath another Hanging Sign
  • Unlike normal Signs, they cannot be placed directly on the ground without support from the side or above
    • However, Hanging Signs that have a horizontal bar will not pop when the supporting block is removed


  • Various wood types now have unique sounds when placed, broken, or walked on
    • There are three sets of unique sounds: Overworld wood types, Nether wood types, and Bamboo

Changes in 22w42a

  • Reworked the Creative Inventory tabs
  • Changes to chat
  • The Realms News button will now show a confirmation screen before opening the link
  • Stronghold placement code has been changed to be more efficient, causing stronghold positions to shift
    • They are still placed in concentric rings, but their positions in the rings may change by a few degrees

Creative Inventory

The ordering of tabs and the contents in the Creative Inventory have been tweaked to make the experience of finding relevant blocks and items easier.

  • Blocks and items have been moved into categories that fit them better
  • Blocks are now ordered by their material as much as possible
    • For example, all Oak blocks and variants are now next to each other
  • Some items can now be found in more than one tab
  • Various tabs have been renamed or collapsed into others
  • The search tab now lists items sequentially grouped by the other tabs
    • For example, items found in Building Blocks will always appear before items in Redstone Blocks
  • Petrified Oak Slab has been removed from the Creative Inventory
    • It can still be accessed through commands
  • This is a first iteration to bring a better experience to the Creative Inventory, and we will look closely at the feedback for these changes to iterate as needed


  • Removed Chat Preview
  • Chat messages deleted by server moderators will no longer be completely hidden, but rather replaced with text stating “This chat message has been deleted by the server.”
  • Deleted chat messages will now be displayed in the chat window for at least 3 total seconds before being hidden
  • The Chat Trust Status indicators have been tweaked:
    • The ‘Modified’ tag will no longer display for server-modified messages where only style has been changed
    • The ‘Modified’ tag icon and indicator is now dark gray
    • The ‘Not Secure’ tag is now light gray and does not have an icon
  • Partially filtered chat messages now show the filtered text as gray hashes with a hover text saying that it was filtered

Technical Changes in 22w42a

  • Added Feature Flags - world options to enable or disable some experimental or unfinished features (like blocks, entities and items)
  • Network protocol changes
  • Instances of recipe types that have recipe books now have field category to determine placement

Feature flags

General notes

  • Feature flags are options that enable or disable certain groups of game elements (like blocks, entities and items), later called “features”
  • Game elements controlled by flags are hardcoded
  • Feature flags are stored in world

Configuration and datapack changes

  • Feature flags are enabled by datapacks
    • New pack metadata section called features is added, containing enabled feature flags in list named enabled
  • The game now contains built-in datapacks (similar to the “Programmer Art” resource pack) that enable features and provide associated recipes, advancements, loot tables, etc
  • Added new fields to server.properties to allow initial selection of packs (works only during world creation)
    • initial-enabled-packs - comma-separated list of packs to be enabled (feature packs need to be explicitly enabled)
    • initial-disabled-packs - comma-separated list of packs to not auto-enable
  • Datapacks discovered after world creation will be disabled if they require features that are not enabled for loaded world

Effects of feature flags


  • Disabled block ids are not recognized by commands that can create new blocks
  • Block items for disabled blocks are disabled
  • Disabled blocks won’t spawn in structures
  • Disabled blocks won’t be loaded as part of entities (for example as falling sand or blocks carried by Endermen)

  • Disabled entities will not spawn or load

Network Protocol

  • Servers can now lazily distribute players’ profile public keys along with their first chat packet
  • Message ‘headers’ within the Secure Chat protocol no longer need to be distributed when private messages are sent
  • Contextual message references are now deduplicated for efficiency within the Secure Chat network protocol


Crafting book categories

  • Crafting book categories/tabs can now be controlled by recipe definitions
  • Categories available for shaped/shapeless and various special crafting recipes:
    • building
    • redstone
    • equipment
    • misc (default)
  • Categories available for smelting, blastingsmokingcampfire_cooking
    • food
    • blocks
    • misc (default)
  • Some crafting books collapse multiple categories into a single tab
  • The exact mappings might change in the future

Resource Packs

  • The Resource Pack version is now 11
  • Removed “fixers” for resource packs with versions 3 and 4 (pre-flattening)
