The feren OS project has previously released editions featuring the Cinnamon, MATE and Xfce desktop environments. This past week the project announced an experimental spin featuring KDE Plasma and based on Ubuntu's 18.10 Beta release. "Another new build for experimental ISO of feren OS is now available, showing the early workings of what feren OS could be like with the KDE desktop environment. Note that what you see in the ISO is nowhere near the finished product, with a lot of change planned over time, some of which will potentially make the experience as a whole feel different, and all the ISO is right now is the accumulation of the default settings and experience for KDE being put in the OS. This means that the ISO is nowhere near the final product still." More details on this experimental spin can be found on the project's blog.
