1 Title: Do not fail on non-existing Livestatus columns any longer, output None or null instead
9 When you ask for a column that does not exist in your Livestatus version, now this is not
10 considered as a fatal error any longer but just being logged as a warning. Instead
11 an empty string (CSV), <tt>None</tt> (Python) or <tt>null</tt> (JSON) is being returned.
12 This makes it easier for GUIs to maintain compatibility with existing Livestatus version
13 when new features are implemented that make use of new Livestatus columns.
