#15495 5b99e90 Thanks @leekeh! - Adds new middlewareMode adapter feature and deprecates edgeMiddleware option

The edgeMiddleware option is now deprecated and will be removed in a future release, so users should transition to using the new middlewareMode feature as soon as possible.

export default defineConfig({
  adapter: vercel({
-    edgeMiddleware: true
+    middlewareMode: 'edge'
  })
})

#15495 5b99e90 Thanks @leekeh! - Refactors to use middlewareMode adapter feature (set to classic)

#15657 cb625b6 Thanks @qzio! - Adds a new security.actionBodySizeLimit option to configure the maximum size of Astro Actions request bodies.

This lets you increase the default 1 MB limit when your actions need to accept larger payloads. For example, actions that handle file uploads or large JSON payloads can now opt in to a higher limit.

If you do not set this option, Astro continues to enforce the 1 MB default to help prevent abuse.

// astro.config.mjs
export default defineConfig({
  security: {
    actionBodySizeLimit: 10 * 1024 * 1024, // set to 10 MB
  },
});

#15495 5b99e90 Thanks @leekeh! - Adds a new middlewareMode adapter feature to replace the previous edgeMiddleware option.

This feature only impacts adapter authors. If your adapter supports edgeMiddleware, you should upgrade to the new middlewareMode option to specify the middleware mode for your adapter as soon as possible. The edgeMiddleware feature is deprecated and will be removed in a future major release.

export default function createIntegration() {
  return {
    name: '@example/my-adapter',
    hooks: {
      'astro:config:done': ({ setAdapter }) => {
        setAdapter({
          name: '@example/my-adapter',
          serverEntrypoint: '@example/my-adapter/server.js',
          adapterFeatures: {
-            edgeMiddleware: true
+            middlewareMode: 'edge'
          }
        });
      },
    },
  };
}

#15679 19ba822 Thanks @matthewp! - Fixes server-rendered routes returning 404 errors

A configuration error in the build output prevented Netlify from correctly routing requests to server-rendered pages, causing them to return 404 errors. This fix ensures that all server routes are properly handled by the Netlify SSR function.

#15646 0dd9d00 Thanks @delucis! - Removes redundant fetchpriority attributes from the output of Astro’s <Image> component

Previously, Astro would always include fetchpriority="auto" on images not using the priority attribute. However, this is the default value, so specifying it is redundant. This change omits the attribute by default.

#15669 d5a888b Thanks @florian-lefebvre! - Removes the cssesc dependency

This CommonJS dependency could sometimes cause errors because Astro is ESM-only. It is now replaced with a built-in ESM-friendly implementation.
