   where mixed up, `default_dayevent_duration` is the default for all-day events
+* NEW event format option `status-symbol` which represents the status of an
+  event with a symbol (e.g. `✓` for confirmed, `✗` for cancelled, `?` for
+  tentative)
+* NEW event format option `partstat-symbol` which represents the participation
+  status of an event with a symbol (e.g. `✓` for accepted, `✗` for declined,
+  `?` for tentative); partication status is shown for the email addresses
+  configured for the event's calendar
