Changes

Comparison of the terracotta texture changes.

Glazed Terracotta

Items

Fishing rods

General

Achievements

• Removed and replaced by advancements.

Crafting

Java version

• This is the first snapshot to use, and thus require, Java 8.

Moving backwards

• The player's body now entirely faces to the front, when moving backwards.
  • 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

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)
