+The `build.split` and `build.excludeMiddleware` configuration options are deprecated and have been replaced by options in the adapter config.
+
+If your config includes the `build.excludeMiddleware` option, replace it with `edgeMiddleware` in your adapter options:
+
+```diff
+import { defineConfig } from "astro/config";
+import vercel from "@astrojs/vercel/serverless";
+
+export default defineConfig({
+     build: {
+-        excludeMiddleware: true
+     },
+     adapter: vercel({
++        edgeMiddleware: true
+     }),
+});
+```
+
+If your config includes the `build.split` option, replace it with `functionPerRoute` in your adapter options:
+
+```diff
+import { defineConfig } from "astro/config";
+import vercel from "@astrojs/vercel/serverless";
+
+export default defineConfig({
+     build: {
+-        split: true
+     },
+     adapter: vercel({
++        functionPerRoute: true
+     }),
+});
+```
