+
+[!INCLUDE [Microsoft Edge team note for top of What's New](../../includes/edge-whats-new-note.md)]
+
+
+<!-- ====================================================================== -->
+## Detached Elements profiling type in Memory tool
+
+<!-- Subtitle: Detached elements helps you fix memory leaks due to detached DOM elements.-->
+
+The **Memory** tool has a new profiling type called **Detached elements**, which shows detached objects that are retained by a JavaScript reference:
+
+![Detached elements profiling type](./devtools-130-images/detached-elements-profile-type.png)
+
+The **Detached elements** profiling type shows a view of the detached nodes to help you identify memory leaks on your webpage:
+
+![Detached elements view](./devtools-130-images/detached-nodes.png)
+
+See also:
+* [Debug DOM memory leaks with the Detached Elements feature](../../../memory-problems/dom-leaks.md)
+
+
+<!-- ====================================================================== -->
+## Improved names of JavaScript objects in heap snapshots
+
+<!-- Plain JavaScript objects are named, categorized, and searchable based on the properties they contain.-->
+
+To help differentiate plain JavaScript objects in the **Object** category, they are now named and categorized based on the properties they contain.  These names are also searchable if you press **Ctrl+F**.
+
+See also:
+* [Record heap snapshots using the Memory tool](../../../memory-problems/heap-snapshots.md)
+
+
+<!-- ====================================================================== -->
+## Create a collection or environment in Network Console
+
+<!-- Subtitle: Use collections and environments to manage API requests and its values and variables. -->
+
+Previously, in the **Network Console** tool, when you tried to create a new collection or environment, it was unresponsive and wouldn't save after pressing **Enter**.  This bug is fixed and functionality has been restored.
+
+![Network Console collection and environment](./devtools-130-images/create-collection-environment.png)
+
+See also:
+* [Compose and send web API requests using the Network Console tool](../../../network-console/network-console-tool.md)
+
+
+<!-- ====================================================================== -->
+## Fixed icon alignment in vertical Activity Bar
+
+<!-- Subtitle: Icons in the Activity Bar are properly aligned horizontally. -->
+
+When the **Activity Bar** was vertical, the icons were left-aligned:
+
+![Broken activity bar icons](./devtools-130-images/misaligned-icons.png)
+
+This has been fixed:
+
+![Fixed activity bar icons](./devtools-130-images/aligned-icons.png)
+
+See also:
+* [Overview of the user interface](../../../overview.md#overview-of-the-user-interface) in _Overview of DevTools_.
+
+
+<!-- ====================================================================== -->
+## Removed circle shadow when hover over toolbar icons
+
+<!-- Subtitle: Icons in toolbars show only a square shadow when hovered over, instead of a circular shadow as well. -->
+
+Many icons in the **Activity Bar** and other toolbars showed an overlapping circle and square shadow when you hovered over them:
+
+![Double shadow on icon](./devtools-130-images/double-shadow-icon.png)
+
+The double shadow has been removed, and the icon only shows the square shadow when you hover over it:
+
+![Single shadow on icon](./devtools-130-images/single-shadow-icon.png)
+
+See also:
+* [Overview of the user interface](../../../overview.md#overview-of-the-user-interface) in _Overview of DevTools_.
+
+
+<!-- ====================================================================== -->
+## Performance tool tab warning icon when throttling
+
+<!-- Subtitle: The Performance tab icon gets a warning icon when throttling is enabled. -->
+
+When throttling is enabled in **Device Emulation**, a warning icon is displayed in the **Performance** tab of the toolbar to help you know that performance is impacted by throttling:
+
+![Performance tab warning icon](./devtools-130-images/performance-warning-icon.png)
+
+See also:
+* [Throttle the network and CPU](../../../device-mode/index.md#throttle-the-network-and-cpu) in _Emulate mobile devices (Device Emulation)_.
+
+
+<!-- ====================================================================== -->
+## Console's Warnings count button has increased contrast
+
+<!-- Subtitle: The warning icon and expand button on warning messages in the Console now meet the standard luminosity ratio of 3:1.-->
+
+In the **Console** tool, the Warning count expander button on warning messages in the **Console** previously didn't meet the standard luminosity ratio of 3:1.
+
+![Low luminosity ratio for the Warning count expander button](./devtools-130-images/console-icon-luminosity-ratio-before.png)
+
+This has now been fixed; the Warning count expander button has a higher luminosity ratio:
+
+![High luminosity ratio for the Warning count expander button](./devtools-130-images/console-icon-luminosity-ratio-after.png)
+
+
+See also:
+* [Inspect and filter information on the current webpage](../../../console/index.md#inspect-and-filter-information-on-the-current-webpage) in _Console overview_.

+
+<!-- ====================================================================== -->
