Announced four days ago, on July 11, Linux kernel 4.6.4 has been introduced by Greg Kroah-Hartman as being a pretty small maintenance update changing a total of 36 files, with 216 insertions and 98 deletions. However, the developer urged GNU/Linux distribution maintainers to upgrade to this version as soon as possible. After four days of testing, the Arch Linux developers managed to push the Linux 4.6.4 kernel to the stable channels, and you can upgrade your installation as we speak by running the “pacman -Syu” command in your favorite terminal emulator, and we always recommend that you keep your OS up-to-date with the latest security patches.
