A new Minecraft update has arrived today, bringing Snapshot 21W44A to the Java edition of the game. And we’ve got the patch notes for you right here!


The Minecraft Java Edition has made its way to Game Pass for PC, part two of the Caves and Cliffs update is on the way and the Minecraft Snapshot 21W44A update is here to bring changes and fixes to the game that range from small ones to larger, more substantial ones.

So for all you need to know about what comes with this latest update, a small one before the larger one lands in a few weeks, and what fixes have been made, here is the lowdown!

Minecraft 21W44A patch notes

Head on over to Minecraft.net for the full debrief on what’s new and what could be on the way, but here are the main takeaways for the changes in Minecraft Snapshot 21W44A.

Minecraft 21W44A new features

  • New world generation is now inserted under existing chunks when upgrading a world to the new world height

Minecraft 21W44A changes

  • Sleeping now only resets the weather cycle if it was raining
