The version of Phaser downloaded from this page is not the current stable release.
This is the first official release of Phaser 3. It represents months of hard work and effort from the Phaser team and wider community.
Please understand that because it is such a massive release and different from Phaser 2 that there is no Change Log entry available for this specific version. The Change Log will continue, in as much detail as before, with all subsequent versions.
