ID: 2229 Title: Do not fail on non-existing Livestatus columns any longer, output None or null instead Component: Livestatus Level: 1 Class: New Feature Version: 1.2.7i1 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), <tt>None</tt> (Python) or <tt>null</tt> (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.
