+### Feature order in the Popup and Features widget
+The [Popup](https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Popup.html) and [Features](https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Features.html) widgets now display features from multiple layers in the order they are displayed in the map. This means that the features of the topmost layer in the map will appear first, followed by the features of the next layer, and so on. In previous versions, the features were displayed in the order they were returned from the server.

 ## Breaking Changes
 
 - At version 4.29, only WebGL2-enabled browsers are supported for both 2D and 3D. See the [System Requirements](https://developers.arcgis.com/javascript/latest/system-requirements/) for more information.
 - For local builds, using [Webpack](https://webpack.js.org/) versions prior to `5.84.0` is not recommended for 4.29. This is related to bug fixes in Webpack.
