+- Unknown settings now generate a warning message instead of failing the
+  image build. This allows configs to work across a wider range of mkosi
+  versions while still taking advantage of newer settings. MinimumVersion
+  can still be used to enforce a minimum version of mkosi that knows all
+  required settings.
