Another week, another Linux kernel surfaces the web in an attempt to improve the security and performance of your GNU/Linux distribution and the hardware that power's your personal computer.
Linux kernel 4.9.6 is the sixth maintenance update to the Linux 4.9 branch, which was recently declared as LTS (Long Term Support) by renowned Linux kernel maintainer Greg Kroah-Hartman. These days, most Linux-based operating systems are still in the process of migrating to the Linux 4.9 series from Linux 4.8, which reached end of life earlier this month.
The new Linux 4.9 point release comes about one week from the launch of the Linux kernel 4.9.5 update, and, according to the appended shortlog, it changes a total of 136 files, with 1030 insertions and 814 deletions. Therefore, we can say that it's a pretty big release, and you should install it on your distro as soon as it lands in the stable software repositories.
