Changes[edit]

Blocks[edit]

Comparison of the terracotta texture changes.
Glazed Terracotta
  • Textured changed for cyan, magenta, orange, and white glazed terracotta, to remove unintentional and potentially offensive imagery.[2]
Beacons
  • Now display their name when hovering over them.
Enchantment Table
  • Now display their name when hovering over them.

General[edit]

Achievements
  • Removed and replaced by advancements.
Crafting
  • Closing the crafting interface with items inside will no longer drop the items in front of you, but will send them instead to the inventory.
Java version
  • This is the first snapshot to use, and thus require, Java 8.[3]
Moving backwards
  • The player's body now entirely faces to the front, when moving backwards.[4][5]
    • Prior to this snapshot, moving backwards would cause the player model to rotate one side, making it look like the player was strafing backwards somewhat.

Fixes[edit]

2 issues fixed
From the previous development version
  • MC-113377 – New block Swastika
  • MC-113844 – White Glazed Terracotta symbol (looks like the symbol of the Hungarian Nazi party)
