Right now we build Kolab 16 for CentOS/RH 7 and Debian 8/9.
RHEL 8 has been released, so CentOS 8 is probably not too far away.
Debian 10 (buster) is in freeze and should also near its release.
So I'd like to suggest to add RHEL/CentOS 8 and Debian 10 to Kolab 16.
For Winterfell we should probably drop the old Fedora releases.
Debian 9 packages can't build or release - should probably be fixed.
(no build type Kube:Winterfell) - Should that be Kolab?
So I'd like to suggest to add RHEL/CentOS 8 and Debian 10 to Kolab Winterfell.
