Compatibility Matrix of Legacy releases

This page contains a compatibility matrix of releases that are either in Extended Maintenance or already reached End of Life. We keep such a matrix for historical reasons mainly and for deployments that forgot to get updated in time.

Operating systems with experimental support are marked with E in the table.
