+
+Structured Reports ISO 8601 Standard Date
+The structured reports (JSON and XML) now have an ISO 8601 standard date field/attribute (“created”);
+the existing “generatedString” field will be removed in the future.
+
+Active Scan Temporary HTTP Messages
+If this option is selected the active scanner will persist all HTTP messages sent while active scanning, which allows to further inspect them (e.g. custom passive scanners, manually).
+They are temporary and removed once the session is closed, for cases where the HTTP messages are not necessary it is advised to disable this option for performance reasons (I/O, disk space).
+
+By default the HTTP messages are persisted unless in command line mode, where sessions are usually discarded once ZAP finishes.
