On this page
This page covers a development version that has a major issue under certain conditions.
 
The dedicated server for this version has a security vulnerability in the Log4j library that could be used to perform a remote code execution exploit. It can be addressed by appending a certain JVM argument to the server startup command line.[1]

16w21b is the third and final snapshot for Java Edition 1.10, released on May 26, 2016,[2] which adds a few splashes, modifies the /tp command, and fixes some bugs from 16w21a.

Additions

General

Splashes

  • Added the following splashes:
    • "Rule #1: it's never my fault".
    • "Replaced molten cheese with blood?"
    • "Absolutely fixed relatively broken coordinates".
    • "Boats FTW".

Changes

Command format

/tp

  • Relative coordinates are now relative to the executor of the command, not the teleported entity.
    • /execute can be used to get the old behavior.
  • /tp can now teleport the player to a Y-coordinate in the range -4096 to 4096 (increased from -512 to 512).

Fixes

5 issues fixed

From the previous development version

  • MC-102509 – Block breaking/fallingdust particles have the wrong color.
  • MC-102511 – Lava texture is incorrectly displayed.
  • MC-102524 – Lighting bug in inventory.
  • MC-102543 – Everything related to structure blocks is black.
  • MC-102572 – Sign's GUI is dark.

Trivia

  • 16w21b was previously removed from the launcher for some time, but was added back in September 2018.
  • "Replaced molten cheese with blood?" is a technical reference to 15w14a, which changed lava to "Molten Cheese"
