Changes in 1.17 Pre-Release 1

  • Blue axolotls can now only be obtained through breeding
  • Non-screaming goats now have a rare chance to produce a screaming goat when bred
  • Status effects on goats now also apply when the goat is jumping or ramming
  • Raised the drop rate for copper ingots from Drowned to 11% + 2% per level of looting
  • Powder snow now fills cauldrons 2 times faster than before (still pretty slowly, though!)
  • Zombies, Zombie Villagers, Husks and Drowned will no longer pick up glow ink sacs

Technical Changes in 1.17 Pre-Release 1

  • In case of DNS-based redirection, the client will send the hostname actually used to connect (this restores the pre-1.17 behaviour)
