As an endpoint for other services or calendar subscriptions, it is interesting not only to delete events and overwrite them all, but also to keep a changelog of changes to the events.
Real changes cannot be tracked but a delete and insert list with the changelog timestamp are possible.
If more information or another way is available to create a history with the new API, please comment and do some research.
