 A new [*drag*.container](https://github.com/d3/d3-drag#drag_container) method lets you override the parent element that defines the drag gesture coordinate system. This defaults to the parent node of the element to which the drag behavior was applied. For dragging on Canvas elements, you probably want to use the Canvas element as the container.
 
-[Drag events](https://github.com/d3/d3-drag#drag-events) now expose an [*event*.on](https://github.com/d3/d3-drag#event_on) method for registering temporary listeners for duration of the current drag gesture. These temporary listeners can capture local state for the current gesture, such as the thing being dragged. A new *event*.active property lets you detect whether multiple (multitouch) drag gestures are active concurrently. The *dragstart* and *dragend* events have been renamed to *start* and *end*. By default, drag behaviors now ignore right-clicks intended for the context menu; use [*drag*.filter](https://github.com/d3/d3-drag#drag_filter) to control which events are ignored. The drag behavior also ignores emulated mouse events on iOS.

 The new [d3.dragEnable](https://github.com/d3/d3-drag#dragEnable) and [d3.dragDisable](https://github.com/d3/d3-drag#dragDisable) methods provide a low-level API for implementing drag gestures across browsers and devices. These methods are also used by other D3 components, such as the [brush](#brushes-d3-brush).
