# What's New in DevTools (Microsoft Edge 136)

These are the latest features in the Stable release of Microsoft Edge DevTools.


<!-- ====================================================================== -->
## DOM tree in Elements tool highlights semantic errors

<!-- Subtitle: DOM elements with semantic errors are highlighted with a wavy line and a tooltip with a link. -->

You can now easily identify semantic issues in the DOM tree of the **Elements** tool, such as:
* An invalid descendant of `<select>`.
* Mismatched ARIA definitions.
* Missing ARIA attributes.

Each DOM node that has a semantic issue displays a red wavy line, and has a tooltip with details about the specific issue and a link to the entry in the **Issues** tool:

![DOM adorner in Elements](./devtools-136-images/dom-adorner.png)

To enable this feature, in DevTools experiments, select the checkbox [Highlights a violating node or attribute in the Elements panel DOM tree](../../../experimental-features/index.md#highlights-a-violating-node-or-attribute-in-the-elements-panel-dom-tree).
