Helo Fedora Users, as Kasun told on his email to the Darktable Community, more testers are needed so version 1.6.6 can be available for everyone.
Darktable 1.6.6 is actually on testing repos. Once users confirm that everything works, it will automatically be sent to the updates repo so it can be available for everyone. If you want to be a tester, this is what you must do:
Step 1: Install darktable 1.6.6 from the testing repo using the following line.
Step 2: Open the app and check how it works.

Step 3: Click on the link corresponding to your Fedora version and log in (you must create a Fedora account in case you don’t have one).
Step 4: Write “Works for me” at comments.
And that’s it! Darktable 1.6.6 will be public!
