Update Aquatic

The Update Aquatic is the name for a major update that was released for all of the Minecraft editions during the summer of 2018, except for the New Nintendo 3DS Edition, for which the Update Aquatic has not yet been released.

The update was released on Java Edition on July 18, 2018 as version 1.13.

The official name for the update, the Update Aquatic, was revealed on November 18, 2017, during the MINECON Earth 2017 livestream, at which time the Java Edition was to be released as 1.14.

Jeb had stated in a 2011 interview that he wanted to implement more sea life into the game.
