Turris OS 4.0 is out! - https://forum.turris.cz/t/turris-os-4-0-is-out/11182
> We just released an important milestone - Turris OS 4.0. This is the release based on OpenWrt 18.06 that spent quite some time in various forms of testing. It completely changes how we make our releases and we are now much closer to the upstream then we’ve ever been.
