Custom Applications deployment previews

Custom Applications now let you generate deployment previews, where you can test new features without affecting the production version of your application.

If you're using the legacy workaround of creating multiple Custom Applications with different entry points, we recommend migrating to deployment previews. They provide a better developer experience with less maintenance since you only need to configure one Custom Application.

As always, if you have questions or feedback, you can open a GitHub Discussion or a GitHub Issue.
