+Remove the Netlify Edge adapter
+
+ `@astrojs/netlify/functions` now supports Edge middleware, so a separate adapter for Edge itself (deploying your entire app to the edge) is no longer necessary. Please update your Astro config to reflect this change:
+
+ ```diff
+ // astro.config.mjs
+import { defineConfig } from 'astro/config';
+- import netlify from '@astrojs/netlify/edge';
++ import netlify from '@astrojs/netlify/functions';
+
+export default defineConfig({
+  output: 'server',
+  adapter: netlify({
++    edgeMiddleware: true
+  }),
+});
+```
+
+This adapter had several known limitations and compatibility issues that prevented many people from using it in production. To reduce maintenance costs and because we have a better story with Serveless + Edge Middleware, we are removing the Edge adapter.

-### Edge Functions
-
-Netlify has two serverless platforms, [Netlify Functions](https://docs.netlify.com/functions/overview/) and [Netlify Edge Functions](https://docs.netlify.com/edge-functions/overview/). With Edge Functions your code is distributed closer to your users, lowering latency.
-
-To deploy with Edge Functions, use `netlify/edge-functions` in the Astro config file instead of `netlify/functions`.

-```js ins={3}
-// astro.config.mjs
-import { defineConfig } from 'astro/config';
-import netlify from '@astrojs/netlify/edge-functions';
-
-export default defineConfig({
-  output: 'server',
-  adapter: netlify(),

 ### Run middleware in Edge Functions
 
 When deploying to Netlify Functions, you can choose to use an Edge Function to run your Astro middleware.
