In this release, we added support for a new Linux distribution.

Use OpenSUSE 15/SUSE Linux Enterprise Server 15 with ClusterControl.

OpenSUSE is an open-source community project with Linux-based distributions sponsored by SUSE Software Solutions Germany GmbH and other companies.

SUSE Linux Enterprise Server (SLES) receives more intense testing than the upstream OpenSUSE community distro, intending that only mature, stable versions of packages will make it through to SLES.
