Coming five months after the release of Linux Lite 3.4, Linux Lite 3.6 is based on Canonical’s latest Ubuntu 16.04.3 LTS (Xenial Xerus) operating system, which means that it’s powered by its long-term supported Linux 4.4 kernel, though users can install a wide range of kernels from the distro’s stable repositories. Linux Lite 3.6 also introduces the Lite Sources in-house built app and several improvements across the entire system. Apart from the new Lite Sources app, which can be found under the Settings section of the Application Menu, and the new search engine for the Linux Lite Help Manual, Linux Lite 3.6 adds an Arc GTK+ theme for the Mozilla Thunderbird email and news client, which was updated to version 52.2.1, better Blu-Ray and Broadcom wireless support, minor GUI changes to both Lite Upgrade and Lite Welcome in-house built apps, and a set of new wallpapers.
