 Note that `renderWhenVisible` defers rendering while the view is not visible and caters to the latest execution call. This provides responsiveness for dynamic content while ensuring performance optimizations.
 
 Ensure your view logic is prepared to handle potentially multiple deferrals if using this API, as only the last call to renderWhenVisible will be queued for execution upon the view becoming visible.

 ## Open MCT v2.0.0
+
 Support for our legacy bundle-based API, and the libraries that it was built on (like Angular 1.x), have now been removed entirely from this repository.
 
 For now if you have an Open MCT application that makes use of the legacy API, [a plugin](https://github.com/nasa/openmct-legacy-plugin) is provided that bootstraps the legacy bundling mechanism and API. This plugin will not be maintained over the long term however, and the legacy support plugin will not be tested for compatibility with future versions of Open MCT. It is provided for convenience only.
 
 ### How do I know if I am using legacy API?
+
 You might still be using legacy API if your source code

+- Contains files named bundle.js, or bundle.json,

 ### What should I do if I am using legacy API?
