# Upgrade guide for Scheduler Pro v4.2.0

## EventDragCreate

The `EventDragCreate` feature now operates on a live instance of a new `EventModel` which is in the `EventStore` on a
provisional basis until either confirmed or cancelled by the `EventEdit` UI.

The end times are manipulated live, and the UI performs appropriate updates. This is in contrast to having a proxy
element dragged in place where an event *may* be placed if inserted.

If you have your own implementation of an event editor/task editor that is shown when drag create ends, this change 
might affect its behaviour. If you need to know if the event being edited is the result of a drag create operation (or a 
double click on the timeline), you can inspect the new `isCreating` flag of the event/task record.

## Dependencies can now be created by dropping anywhere on the event bar element

In previous versions you had to hit a specific side circle element to define it. The new behavior allows you to
setup a dependency by dropping anywhere on the task bar. This creates a dependency with the default type, as
defined by the `defaultValue` of the DependencyModel `type` field.

If you prefer the old behavior, simply set `allowDropOnEventBar` to false on the feature config:

```javascript
const scheduler = new Scheduler({
    features : {
        dependencies : {
            allowDropOnEventBar : false
        }
    }
});
```
