From the release:
The new version of Fate has changed their open license to make it friendlier to game designers who want to base their game on Fate. This change has made it possible to create a Fate version of the rules for Extreme Future.
Extreme Future (Fate Edition) takes the popular Fate rules and pairs them with the Extreme Future setting to create a Sci-Fi role-playing game with award winning rules. Everything needed to play is contained in the pdf. It is available on RPGDriveThru.
