1.17.1 is an upcoming minor update to Java Edition, with no set release date.[1]

Changes

Blocks

Cauldrons
  • Powder snow now fills cauldrons 2 times as fast as before.

Mobs

Axolotl
  • Blue axolotls now only spawn through breeding.
Drowned
  • Increased the drop probability of copper ingot from 5% to 11%, and increased the drop rate boost with each level of Looting spell from 1% to 2%.
Goats
  • Breeding common goats now has a chance to produce screaming goats.
  • Status effects applied to goat goats now also apply when the goat is jumping or ramming.
Zombies, Zombie Villagers, Husks and Drowned
  • No longer pick up glow ink sacs.
    • This prevents zombies from persisting after picking up the loot of a dead glow squid.

General

Protocol
  • Handshake packet padding method for "hostname" and "port" field has reverted to pre-1.17 when the server address which used is a SRV record.
    • Now, data padded in these field will use the address and port which SRV record pointed at, instead of using "server address" as "hostname" and 25565 as "port".
