Minecraft: Java Edition Snapshot 22w19a tests `Chat Preview` feature, more fixes

Source: Mojang Studios | Twitter

Minecraft: Java Edition, the legacy version of Minecraft that started it all, gains a new snapshot almost every week that gives players a peek into the future of Minecraft. A new content update is arriving later this year, and Mojang Studios has been tirelessly developing the release ahead of its eventual launch. On Thursday, Minecraft: Java Edition Snapshot 22w19a began rolling out to interested players.

The latest Minecraft snapshot continues to build off The Wild Update, a sizeable content-filled update releasing at some point in 2022. This isn’t the most exciting snapshot for most players, besides a handful of bug fixes and smaller changes, but those mired In the technical or creator aspect of Minecraft may be intrigued.

The headlining feature of this release is none other than the Chat Preview, a new feature that servers can now test through this snapshot, which allows a preview of server-altered chat to appear above the chat edit window for players. Mojang Studios’ infamous PC game also enjoys a handful of other changes for command lines, and more.

In case you missed it, Minecraft: Bedrock Edition Beta is also now available, alongside the news that some features originally slated for release with The Wild Update have now been cut, like fireflies.

    • The server then sends back the styled preview in real time

  • A warning screen is shown on the client when joining a server with Chat Preview, and it can be globally disabled in Chat Settings
  • Dynamic chat styling can also be controlled by the server, although this is only signed when Chat Preview is enabled
