The compatibility test reports published. A "Test Passed" status is a 90% assurance that this product will work as intented in the environment tested.
Our system requirements are found here. We now only make new compatibility reports for version 8.0 and higher.
We make the compatibility reports when other vendors release newer versions after our release. This is where you see if e.g a new version of Internet Explorer is compatible with current releases of SuperOffice.
