- **changed** — Cloudflare builds reduce serialization overhead for large prerendered pages
- **added** — Add a Cloudflare `finalize()` response handler for custom request handlers to apply cookies and Cloudflare CDN cache defaults
- **changed** — The `@astrojs/cloudflare/hono` middleware applies response headers automatically
- **changed** — Cloudflare custom entrypoints fall back to static assets when no Astro route matches
- **changed** — Cloudflare custom entrypoints use the default server entrypoint when prerendering through workerd

###### Minor Changes

-   [#17795](https://github.com/withastro/astro/pull/17795) [`15e2deb`](https://github.com/withastro/astro/commit/15e2debc7e81d353410ff76a76c3bf75b7fb3070) Thanks [@matthewp](https://github.com/matthewp)! - Adds concurrent rendering support for `experimental.incrementalBuild`, including when using `@astrojs/cloudflare`

    Incremental builds no longer disable caching when `build.concurrency` is greater than `1`. Projects that set `build.concurrency: 1` to keep the cache enabled can remove that workaround. Cloudflare builds also reduce serialization overhead for large prerendered pages.

-   [#17887](https://github.com/withastro/astro/pull/17887) [`35aa62e`](https://github.com/withastro/astro/commit/35aa62e60226d81cda281d0b9355abcfa29d889d) Thanks [@matthewp](https://github.com/matthewp)! - Adds a Cloudflare `finalize()` response handler for custom request handlers

    Call `finalize()` to apply cookies and Cloudflare CDN cache defaults to the response from an `astro/fetch` pipeline:

    ```ts
    import { astro, FetchState } from 'astro/fetch';
    import { cf, finalize } from '@astrojs/cloudflare/fetch';

    export default {
      async fetch(request: Request, env: Env, context: ExecutionContext) {
        const state = new FetchState(request);
        const asset = await cf(state, env, context);
        if (asset) return asset;

        return finalize(state, await astro(state));
      },
    };
    ```

    The `@astrojs/cloudflare/hono` middleware applies these response headers automatically. Cloudflare custom entrypoints also fall back to static assets when no Astro route matches and use the default server entrypoint when prerendering through workerd.
