 - Removed `@fortawesome/font-awesome` and `openshift-logos-icon`. Plugins should use PatternFly icons
   from `@patternfly/react-icons` instead. The `fa-spin` class remains but is deprecated and will be
   removed in the future. Plugins should provide their own CSS to spin icons if needed.
+- Upgraded `monaco-editor` to version `0.51.0`.
 - Removed styling for generic HTML heading elements (e.g., `<h1>`). Use PatternFly components to achieve
   correct styling.
 - Removed `co-m-horizontal-nav` styling. Use [PatternFly Tabs](https://www.patternfly.org/components/tabs/)
