id property
ID is CD's own sequence number for this deploy (status.history[].id). It increases with every applied revision, so the largest id in history is the most recent deploy — which is the first entry, since the list is reversed.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
int? id;
