What you need to know

  • Minecraft: Java Edition tests future updates and features through update "slices" known as snapshots.
  • Minecraft: Java Edition Snapshot 21w13a is available for PC Minecraft players right now.
  • The latest snapshot adds goats and tweaks from the upcoming 'Caves and Cliffs Update.'
  • There's also a new accessibility option for the loading screen and plenty of bug fixes on board too.

Minecraft is all about swapping features in the latest batch of betas and snapshots today. Minecraft: Bedrock Edition got axolotl and deepslate, which had already been tested in a previous Minecraft: Java Edition snapshot. On the other hand, Minecraft: Java Edition Snapshot 21w13a has just arrived on scene with the new goat mob, which appeared in a past Minecraft: Bedrock Edition beta.

The latest Minecraft: Java Edition snapshot is now available to Minecraft: Java Edition snapshot players, and features a new mob and more tweaks from the upcoming Caves and Cliffs Update. Players can also find a ton of tweaks and changes to existing features and previously-tested additions, a new accessibility option, and the usual batch of bug fixes and general improvements. The highlight for this snapshot is certainly the goats, a new neutral mob that resides in Minecraft's mountains and boasts of some impressive jumping power.

You can play the new Minecraft: Java Edition snapshot right now.
