You’re reading the docs for Phaser Editor v4. The latest is Phaser Editor v5.

Updating the editor

When you start the server, it connects with the updates site in Internet and checks if there is a new version. If there is a new version then it shows a message with the version number and some headlines of the release notes.

The Phaser Editor Desktop distribution shows a message when there is a new update, but you should download the new version manually.

In v3 of the editor, you had the option of installing/updating Phaser Editor Core from NPM. Yet it is not available in Phaser Editor v4.
