         - type: String, The type of the binary
-        - flags: Array of String, The flags associated with the run (e.g. DebugDumped)
+        - debugFlags: Array of String, Flags associated with the debug run (e.g. FailedGracefully)
+        - releaseFlags: Array of String, Flags associated with the release run (e.g. ASANCrashed)
         - debugStackTrace: Object (see fuzzer-stacktrace-sk.html for schema)
         - releaseStackTrace: Object (see fuzzer-stacktrace-sk.html for schema)
+        - category: String.
     detailsBase: String, the base url for details (should include file and function name)
     expand: Boolean, if this element should be auto expanded.
+    exclude: Array of String, all fuzzes that have one or more of these strings as a flag will not
