Minecraft 1.21.9 Pre-Release 2

A Minecraft Java Pre-Release

We heard Friday would be a Pre-tty cool day to release the second Pre-Release for Minecraft: Java Edition 1.21.9, so here we are! This pre-release contains fixes to various issues introduced in previous snapshots, as well as a missed bump to the Data Pack major version.

Happy Crafting!

Changes

  • Copper Golems will now oxidize even when the game rule doDaylightCycle is disabled
  • The Copper Golem's behavior for turning into a statue has been tweaked to match Bedrock
    • Copper Golems no longer need to be close to the center of an empty block position in order to turn into a statue
    • Copper Golems now have the possibility to turn into a statue as soon as they become fully oxidized

Technical Changes

  • The Data Pack version is now 88.0, to match the breaking change to /setworldspawn and /spawnpoint in the 1.21.9-pre1
