1.21.11 Pre-Release 4 (known as 1.21.11-pre4 in the launcher) is the fourth pre-release for Java Edition 1.21.11, released on December 1, 2025.[1]

A separate unobfuscated version of 1.21.11 Pre-Release 4 was released, titled 1.21.11 Pre-Release 4 Unobfuscated (or 1.21.11-pre4_unobfuscated when in the launcher). This is an experimental version released in preparation for obfuscation being removed from Java Edition clients and servers.[2]

Changes

Mobs

Nautilus and zombie nautilus

  • Dispensers can now equip saddles and nautilus armor on tamed nautiluses and zombie nautiluses.
  • Dismounting a nautilus or zombie nautilus while on land no longer places the player inside the nautilus.
    • This works given that there is a valid block to place the player on.
    • If there is no valid block, the player will be placed inside the nautilus as before.
  • Zombie nautilus drops are now affected by Looting.

General

Creative mode

  • The attack range extension for players in Creative mode is set to 2 blocks.
