4MLinux 20.0 has entered development at the beginning of September, when the Core edition was pushed to the Beta channels for early adopters, as well as for the 4MLinux developer to rebase all of his GNU/Linux distribution on the new system, which is now powered by the long-term supported Linux 4.4.27 kernel fully patched against the “Dirty COW” vulnerability. Probably the most important change in the 4MLinux 20.0 release is the implementation of new boot options that let users boot the GNU/Linux distro on both UEFI and Legacy BIOS PCs.
