Minecraft: Java Edition - Snapshot 21w42a

It's time for a musical snapshot! We're now introducing new music for Caves & Cliffs: Part II. This time around we have a bunch of new tracks composed by the talented Lena Raine and Kumi Tanioka. These tracks are also available on Spotify for you to listen to, and they will soon be available on other services such as Apple Music and YouTube as well. 

This snapshot also includes a few additional tweaks, bug fixes, and performance improvements.

We still highly recommend backing up your world before loading it in this snapshot.
