When you ask for a column that does not exist in your Livestatus version, now this is not considered as a fatal error any longer but just being logged as a warning. Instead an empty string (CSV), None (Python) or null (JSON) is being returned. This makes it easier for GUIs to maintain compatibility with existing Livestatus version when new features are implemented that make use of new Livestatus columns.
