In addition, Linux graphic controllers start supporting nVidia Pascal, except GeForce GTX 1060/1070/1080, since to be supported nVidia would have to free the firmware first.
The new kernel version also supports HDMI CEC, meaning one or several devices can be connected via HDMI and controlled with a single remote control.
As usual, this version includes bug fixes, security improvements and improvements in Btrfs, XFS or EXT4 files, that unifies the encryption system with the one of the kernel.
Linux 4.8 will arrive to all distros during the next weeks.
