Notifying users of changes to Events

When a future event is changed, there are no notifications sent to the users who have booked.

For example, if an organiser changes essential details e.g. date, time or location. Anyone who has booked is not notified unless the organiser manually contacts those who have booked.

It would be a great improvement if Abintegro automatically updates booked users to events of any changes, or sends an updated calendar invitation.
