The Fedora 23 Linux OS was released last year, on November 3, and it introduced a bunch of great Open Source apps and GNU/Linux technologies that were popular at that point in time, including the GNOME 3.18 desktop environment, Linux 4.2.0 kernel, a version optimized for running on ARM-based systems and the first Cinnamon Spin. We hate to give you guys bad news, but all good things must come to an end, and it looks like Fedora 23 will reach end of life in approximately three weeks after writing this blog story, on December 20, 2016. After that date, the OS will no longer receive security fixes and software updates, which means that it will be vulnerable to attacks.
