+Removes additional deprecated APIs:
+
+- The Astro preview server now returns a 404 status instead of a 301 redirect when requesting assets from the public directory without a base.
+- Removes special handling when referencing the `astro/client-image` type. You should use the `astro/client` type instead.
+- Removes deprecated built-in `rss` support in `getStaticPaths`. You should use `@astrojs/rss` instead.
+- Removes deprecated `Astro.request.params` support. You should use `Astro.params` instead.
