+### [changed]: `entryPoint` type inside the hook `astro:build:ssr`
+In Astro v4.x, the `entryPoint` type was `RouteData`.
+
+Astro v5.0 the `entryPoint` type is `IntegrationRouteData`, which contains a subset of the `RouteData` type. The fields `isIndex` and `fallbackRoutes` were removed. 
+
+#### What should I do?
+Update your adapter to change the type of `entryPoint` from `RouteData` to `IntegrationRouteData`.
+
+```diff
+-import type {RouteData} from 'astro';
++import type {IntegrationRouteData} from "astro"
+
+-function useRoute(route: RouteData) {
++function useRoute(route: IntegrationRouteData) {
+  
+}

+### [changed]: `routes` type inside the hook `astro:build:done`
+In Astro v4.x, the `routes` type was `RouteData`.

+Astro v5.0 the `routes` type is `IntegrationRouteData`, which contains a subset of the `RouteData` type. The fields `isIndex` and `fallbackRoutes` were removed.

+### [changed]: `RouteData.distURL` is now an array
+In Astro v4.x, `RouteData.distURL` was `undefined` or a `URL`
+
+Astro v5.0, `RouteData.distURL` is `undefined` or an array of `URL`. This was a bug, because a route can generate multiple files on disk, especially when using dynamic routes such as `[slug]` or `[...slug]`.
+
+#### What should I do?
+Update your code to handle `RouteData.distURL` as an array.
+
+```diff
+if (route.distURL) {
+-  if (route.distURL.endsWith('index.html')) {
+-    // do something
+-  }
++  for (const url of route.distURL) {
++    if (url.endsWith('index.html')) {
++      // do something
++    }
++  }
+}
