Currently, the build server, which builds packages for Fedora and Arch Linux, doesn’t support Fedora 22.
So, here is a Fedora 22 version of GDevelop 3.6.80 :

This version will be available in the build server when it will be updated to support Fedora 22.
Nice! Hopefully OBS team won’t wait too much before adding Fedora 22 support! 
GDevelop is now available for Fedora 22 through OpenSUSE Build Service like the Fedora 21 and the Arch Linux packages : software.opensuse.org/download.h … e=gdevelop
Be careful, the instruction detailed in this webpage are not correct anymore because of the new package manager of Fedora. In Fedora 22, to add a repository, you need to execute this command :
sudo dnf config-manager --add-repo http://download.opensuse.org/repositories/home:victorlevasseur/Fedora_22/home:victorlevasseur.repo
