Linus Torvalds introduced the Linux kernel 4.8. You can download the relevant deb packages from HERE and install them. Or just follow the instructions given below that will help you to install a new kernel multiple commands in terminal.

The new version made about 13 thousand corrections from 1500 developers, the size of the patch 41 MB changes 11303 files, added 627751 lines of code, deleted lines 278958). About 39% of all changes associated with device drivers, approximately 21% of changes relate to updating the code for specific hardware architectures, 12% related to the network stack, 5% - file systems and 4% c internal kernel subsystems.
Warning. The Linux kernel is a critical element of the system. To do the upgrade costs when one of your hardware devices is not working properly, and the new kernel may fix this problem. But at the same time installing a new kernel unnecessarily can lead to undesirable regressions, such as: no network connection, no sound or even the inability to boot the system, so install a new kernel on your own risk.
