Back in May the Korora team announced it would be taking a break and the project would not be publishing a new version based on Fedora 28. Since then a volunteer has stepped forward, offering a spin of Korora that is based on Fedora 28 and features the Xfce desktop. "A past contributor, JMiahMan, has produced a Xfce ISO based on Fedora 28 and including the usual Korora additions. There are more details on this Engage item. You might find this blog post interesting too. There are plans to produce ISOs of the other desktops once Xfce is sorted. So even if you don't use Xfce it would be helpful if you could test this system on a live system or in a VM. Remember these are community produced, beta releases and not designed for day to day use (yet!) so we don't recommend installing them on a production system." More details and intructions for leavign feedback can be found in the project's blog post.
