+// stateV2 is a representation of the legacy JSON state format version 3.
+//
+// It is only used to read version 3 JSON files prior to upgrading them to
+// the current format.
+//
+// The differences between version 2 and version 3 are only in the data and
+// not in the structure, so stateV3 actually shares the same structs as
+// stateV2. Type stateV3 represents that the data within is formatted as
+// expected by the V3 format, rather than the V2 format.
