Hi Valent, Following the success my Gimp 2.7. repo had, the Fedora Gimp maintainers created repository called Gimp Unstable[1] which I recommend to provide feedback and bug report to upstream. You can view full details on mail list[2] about porting Gimp to either rawhide or testing repo. My repo will still be available until then.
