Pre-release: July 30, 2012
1.3.1 was a major update to Java Edition released on August 1, 2012, which added trading, adventure mode, new generated structures (jungle and desert pyramids) and new blocks/items including emeralds, book and quills, written books, and tripwire. Initially Mojang were going to add rubies but they replaced those with emeralds. They also added ender chests, and also improved enchanting and split the Creative inventory into separate sections. While it was not the only 1.3 release, it was the only one before the snapshots of 1.4.2 started.

- 1.3 was a version that held several development-related records, until the development of Java Edition 1.8.
- The most snapshots for a major release: 19.
- The longest development period, from first snapshot to final release: 111 days.

- 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 Java Edition 1.2.5 or older versions they will still see the last skin they used before Java Edition 1.8.
- 1.3 is the last update to Java Edition without an official name, and promotional image.
- 1.3.1 has the same amount of snapshots as 1.16.
