A lot of improvements went into the new RaspEX release, which was tagged as build 170810, starting with the replacement of the Linux 4.4 LTS kernel packages that were used in previous versions, with the more newer Linux 4.9 LTS kernel, and continuing with the rebase of the entire OS to Ubuntu 17.04 (Zesty Zapus). RaspEX Build 170810 also uses packages from the Debian GNU/Linux 9 “Stretch” and Linaro repositories and adds Wicd as default network manager, Mozilla Firefox as default web browser to replace Chromium because it features better support for watching YouTube videos.
