+### [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 {IntegrationRouteData} from "astro"

+### [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.
