At this point, it seems that Mojang is releasing another Minecraft Snapshot every other week. This snapshot is quite large, which is good news as it could indicate that the new Minecraft Caves and Cliffs part two may be released soon. This snapshot in particular focuses heavily on world generation, which is the most exciting aspect of the new update.

Minecraft players are waiting patiently for this update as it is going to be the best Minecraft update in history. Some players may have been let down by 1.17, but this update is surely the real deal. Since this Snapshot is one of the largest that Mojang has released, only the most notable changes are listed below.

  • In the Stonecutter, a block of Copper can be converted to 4 Cut Copper
  • Updated ore distribution to make branch mining deep down more rewarding

  • Villages are slightly more spread out
  • Axolotls now only spawn in water, above clay blocks, in lush caves
