+- Route boundaries locked behind a feature flag
+- Panel position settings allow you to change the panel position to either top or bottom of the screen
+- ErrorBoundaries are more precise now
 ## v2.3.0 
 Route tree view support!
 View all your routes in a node tree! You can also open routes in your browser from the tree view.

 - **URL Parameters**: Easily view and analyze the URL parameters associated with the current page.
 - **Server Responses**: Inspect and review the server responses received by the application for the current page.
 - **Loader Data**: Monitor and track the loader data used by the application during page rendering.
-- **Outlet boundaries** Activate the **Show Route Boundaries** option to see each Outlet and route boundaries by coloring the background. This needs to make a GET request to the current route when the dev tools are mounted for the first time to work properly and hence it is locked behind a flag. You can enable it by passing `showRouteBoundaries` prop to `true` in the `RemixDevTools` component.

 - `requireUrlFlag`: Requires rdt=true to be present in the URL search to open the Remix Development Tools. Defaults to `false`.
