Bedrock Edition 1.4.0

1.4, known as Phase One of the Update Aquatic, is a major update to Bedrock Edition that was released on May 16, 2018. It added many new features focused primarily around ocean-related content, such as dolphins, shipwrecks, fish, tridents, buried treasure, drowned, and many other changes and fixes. Some features were also fully implemented that were added through experimental builds from the 1.2.x updates.

Initially set to be released as 1.3, the version name was later changed to skip this number due to issues with version tagging on various platforms. Also, because of the sheer amount of content to be added in Update Aquatic in Bedrock Edition, it was later decided to split the update into two major updates, with things like turtles, conduits and bubble columns being pushed back to Phase Two (1.5).
