-Makes `astro:env` stable
+The `astro:env` feature introduced behind a flag in [v4.10.0](https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#x4100) is no longer experimental and is available for general use.
 
-To upgrade, update your Astro config:
+This feature lets you configure a type-safe schema for your environment variables, and indicate whether they should be available on the server or the client. Import and use your defined variables from the appropriate `/client` or `/server` module:
+
+```astro
+---
+import { API_URL } from "astro:env/client"
+import { API_SECRET_TOKEN } from "astro:env/server"
+
+const data = await fetch(`${API_URL}/users`, {
+  method: "GET",
+  headers: {
+    "Content-Type": "application/json",
+    "Authorization": `Bearer ${API_SECRET_TOKEN}`
+  },
+})
+---
+
+<script>
+import { API_URL } from "astro:env/client"
+
+fetch(`${API_URL}/ping`)
+</script>
+```
+
+If you were previously using this feature, please remove the experimental flag from your Astro config:
 
 ```diff
 import { defineConfig, envField } from 'astro/config'
 
 export default defineConfig({
 -  experimental: {
-    env: {
-      schema: {
-        FOO: envField.string({ /* ... */ })
-      }
-    }
+-    env: {
+-      schema: {
+-        FOO: envField.string({ /* ... */ })
 -      }
+-    }
+-  }
++  env: {
++    schema: {
++      FOO: envField.string({ /* ... */ })
++    }
++  }
 })
 ```
+
+If you have been waiting for stabilization before using `astro:env`, you can now do so.
+
+Please see [Using environment variables](https://docs.astro.build/en/guides/environment-variables/#astroenv) for more about this feature.
