+This change adds an API endpoint for requesting a catalog refresh at `/refresh`, which is activated if a `CatalogProcessingEngine` is passed to `createRouter`.
+The creation of the router has been abstracted behind the `CatalogBuilder` to simplify usage and future changes. The following changes are **changes are required** to your `catalog.ts`.
