Exploration Update

The Exploration Update is the name for version 1.11, a major update released on November 14, 2016. The official name for the update, the Exploration Update, was revealed on September 24, 2016, during the Opening Ceremony at MINECON 2016. During the "Casual Chat with Jens" panel at MINECON, he suggested that the name "Expedition Update" was more suitable to the theme of the update compared to the "Exploration Update".

The main features of the update were announced on the second day of MINECON 2016, during "The Minecraft 1.11 Change Log" on September 25, 2016. However, snapshots for the update initially began around two months prior to the reveal of the main features, with the features being added in a snapshot just a few days after MINECON.

Mojang released the first (and only) pre-release for the Exploration Update on November 8, 2016.
