Added
- Client events are now implemented through `SimConnect::subscribe_to_client_event`, `SimConnect::unsubscribe_from_client_event` and `SimConnect::unsubscribe_from_all_client_events`.
- `subscribe_to_client_events.rs` example has been added.
- `SimConnectError::EventAlreadySubscribedTo` and `SimConnectError::EventNotSubscribedTo` error variants have been added.
Changed
- A second call to `SimConnect::subscribe_to_system_event` for the same event will now return an error of type `SimConnectError::EventAlreadySubscribedTo` instead of `SimConnectError::SimConnectException`.
- The call to `SimConnect::unsubscribe_from_system_event` is now a NOOP when the system event is not subscribed to.
- `SimConnectError::UnimplementedMessageType` has been renamed to `SimConnectError::UnimplementedNotification`.
Removed
- `SimConnect::register_event` has been replaced by the new client event functions.
- `NotificationGroup` has been removed in favor of an internally managed notification group.
