  • The snowy slopes and jagged peaks surfaces have been fixed to work like they did in the experimental snapshots, where some (but not all) sides of the peaks are exposed stone.
  • New random number generator is used for overworld generation.


Chunk render pipeline
  • Changed the prioritization order.
Menu screen
  • Server classes are now signed.
  • Slightly increased the angle in which sprinting against a block would not stop the player from doing so.
