This is a minor maintenance release in the 4MLinux STABLE channel. The release ships with the Linux kernel 4.4.70. Additionally, some popular programs (e.g., GNU GRUB, SMTube, VLC) have been updated, too. As a response to user requests, an RDP client (rdesktop 1.8.3) is now available out of the box.
You can update your 4MLinux by executing the "zk update" command in your terminal (fully automatic process).
