Hi folks,
took me a while but I've submitted ardour4 for review to be included in Fedora 21+:
https://bugzilla.redhat.com/show_bug.cgi?id=1216055
I'd be very grateful if someone would pick up the review.
I've also built binary packages in copr, so if you want to give the new version a whirl, you can do so by enabling the nphilipp/ardour4 copr repo, and installing ardour4. These should later smoothly transition over to the official packages when there are any, so have fun!
