Getting FOG Project
The latest release of FOG Project is v1.5.4, released June 05th 2018.

At this time, a FOG server installation is only supported on a computer running Linux. We recommend using a Long Term Support distribution meant for servers, such as CentOS or Debian, though you can use a variety of other distributions. We also recommend installing FOG Project inside a virtual machine, to aide in easy backups and upgrades.
