We need to have next issues in the list of CRW 2.1 known issues on production, until we release CRW 2.1.1:

• "2.0.0 workspaces cannot be restarted after update from 2.0.0 to 2.1.0" with workaround: to re-create new workspace using devfile of old one

• "Operator ignores server property "workspaceNamespaceDefault" of custom resource file" with workaround: to use "CHE_INFRA_KUBERNETES_NAMESPACE_DEFAULT" in "customCheProperties" section of custom-resource.yaml instead
