+### Tooltip advancements and edge offset inputs
+
+For more control over the positioning of the [tooltips](https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Sketch-SketchViewModel.html#tooltipOptions), this release adds the ability to **drag tooltips** while in input mode.
+
+Additionally, in SceneView, a **new
+distance field for the edge [offset operation](https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Sketch-SketchViewModel.html#defaultUpdateOptions)** can be used for creating exact building
+setbacks or for adjusting property easements. Press Tab to enter the input mode while hovering over the edge offset arrows or when dragging it.
+
+## Viewshed layers in web scenes
+
+Share and present your viewshed analyses by persisting them on the ViewshedLayer in a [web scene](https://developers.arcgis.com/javascript/latest/api-reference/esri-WebScene.html). You can use it as any other layer: include it in slides or toggle its
+visibility through the layer list.
+
+By enabling the `interactive` property on `ViewshedLayerView`, you can adjust the shape of an existing analysis or create new [viewsheds](https://developers.arcgis.com/javascript/latest/api-reference/esri-analysis-Viewshed.html).
