Released 2020 June 19 (build 44.6.19)
Events subscription for personal calendars
All Users can now subscribe their Events to their Google, Outlook, or Apple (Mac) calendar, so that anything visible in Events will be visible in their personal calendar. Each synced calendar event will include the details of the event (name, location, time, description) as well as a link back to the original notice in Events. NOTE—completing your RSVP or any other action must be done in Events and cannot be done from your personal calendar.
System Administrators will need to turn this feature on (by clicking the gear icon in Events and selecting "Enable calendar subscriptions") before users will see the "Subscribe to calendar" option in their Events view.
