elementary OS 0.4.1 is the first point release in the Loki series, which are based on Canonical’s Ubuntu 16.04 LTS (Xenial Xerus) operating system. As expected, this release is based on Ubuntu 16.04.2 LTS, which inherits the kernel and graphics stack from Ubuntu 16.10 (Yakkety Yak), so it’s also powered by the same HWE (Hardware Enablement Stack). Therefore, elementary OS 0.4.1 is powered by the Linux 4.8 kernel, allowing users to install the operating system on their Intel computers boasting 7th generation Kaby Lake chipsets, and the X.Org Server 1.18.4 display server and Mesa 12.0.6 3D Graphics Stack, though users should be able to install Mesa 17.1.0 from Canonical’s X-Updates PPA repository.
