Rebellin Linux 3.5 rolls out as the best GNU/Linux distribution based on Debian Sid, according to the developers, because it comes with out-of-the-box email support. We don’t know what to say about that, but we can’t help but notice that this release includes the latest GNOME 3.22.2 and MATE 1.16.1 desktop environments. Rebellin Linux 3.5 also comes with a brand-new Material Design theme, and it looks like the Rebellin Manual has been made free for all users who want to use the GNU/Linux distribution. A WhatsApp client for Linux is also present in this release, along with better touchpad support.
