The engine now emits events with richer metadata during the ResourceOutputs and ResourcePre callbacks. The CLI can then use this information to decide if it should display the event or not and how much of the event to display. Options dealing with what to display and how to display it have moved into the CLI and the engine now emits all information for each event.
