Sabayon 15.10 is here with a brand-new graphical installer, Calamares, which is also used with success on many other GNU/Linux operating systems, including the Arch Linux-based Manjaro Linux.
While the KDE edition of Sabayon 15.10 ships with the latest KDE Plasma 5 desktop environment, finally replacing the old KDE4 one, the MCE (Media Center Edition) of Sabayon has been dropped, along with the Steam Big Picture mode.
