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]

Additions

Blocks

Concrete

  • Comes in the 16 traditional dye colors.
  • Created when concrete powder comes into contact with still or flowing water.

Concrete powder

  • Comes in the 16 traditional dye colors.
  • Gravity affected (like sand and gravel).
  • When it touches water, it turns into a concrete block.
  • Crafted with 4 sand, 4 gravel and one of any dye to get 8 concrete powder blocks. The recipe is shapeless.

Glazed terracotta

  • Comes in the 16 traditional dye colors.
  • Smelting any colored stained clay in a furnace produces the glazed terracotta of that color (not for regular hardened clay).
  • Can be placed in 4 directions: north, south, west, and east.
    • When placed down while facing the right directions, a repeating pattern can be created. For example, the white glazed terracotta creates the pattern of a sun when 4 are placed down correctly.

General

Creative

  • Added "Saved Toolbars" tab.
    • Save toolbars in Creative mode with ⎈ Control + 1-9/⌘ Command + 1-9 and load them with ⇧ Shift + 1-9.
    • Can save up to 9 toolbars.
    • If an empty toolbar is saved, it clears the bookmarked toolbar and puts back the 'informational paper' in the respective slot.
