prisoninmate quotes a report from Softpedia: Announced for the first time back in November 2014, Devuan is a Debian fork that doesn't use systemd as init system. It took more than two and a half years for it to reach 1.0 milestone, but the wait is now over and Devuan 1.0.0 stable release is here. Based on the packages and software repositories of the Debian GNU/Linux 8 "Jessie" operating system, Devuan 1.0.0 "Jessie" is now considered the first stable version of the GNU/Linux distribution, which stays true to its vision of developing a free Debian OS without systemd. This release is recommended for production use. As Devuan 1.0.0 doesn't ship with systemd, several adjustments needed to be made. For example, the distro uses a systemd-free version of the NetworkManager network connection manager and includes several extra libsystemd0-free packages in its repository.
