Amahi 7 has now been released and I have spent some time upgrading my server (well, reinstalling and fixing everything I had before).
Amahi 7 is based on Fedora 19. I have spent some time fixing a couple of apps for the new Amahi 7 and they should be live soon. Among others Sickbeard and CouchPotato V2.
Amahi 7 can be downloaded from http://amahi.org.
