• #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 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! - 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'
            }
          });
        },
      },
    };
  }
