Minecraft:Java Edition 1.3.1

1.3.1 is a major update to Template:JE released on August 1, 2012,<ref name=1.3/> which added Minecraft:trading, Minecraft:Adventure mode, new generated structures (jungle and Minecraft:desert pyramids), and new blocks/items including Minecraft:emeralds, Minecraft:book and quills, Minecraft:written books, and Minecraft:tripwire. It also adds Minecraft:ender chests, improved Minecraft:enchanting, and splits the Minecraft:Creative inventory into separate sections. This is the first version to use an internal Minecraft:multiplayer server in Minecraft:singleplayer worlds, which resulted in many broken features. While it was not the only 1.3 release, it was the only one before the snapshots of 1.4.2 started.

A pre-release for 1.3.1 was released on July 30, 2012,<ref name=1.3>Template:Cite</ref> though the full release of 1.3.1 is identical to this pre-release.

Trivia

• 1.3 was a version that held several development-related records, until the development of Minecraft:Java Edition 1.8.
  • The most snapshots for a major release: 19.
  • The longest development period, from first snapshot to final release: 111 days.
  • The longest wait between major releases, with a release 153 days after the release of Minecraft:Java Edition 1.2.1 (later broken by the wait time between Java Edition 1.8 and Minecraft:Java Edition 1.9).
• If the player changed their skin after Java Edition 1.8 was released, 1.3.1 would be the oldest version to display that skin change. If the player plays on Minecraft:Java Edition 1.2.5 or older versions they still see the last skin they used before Java Edition 1.8.
• 1.3 is the last major update to Template:JE without an official name and promotional image.
