Contains new features#16187 fe58071 Thanks @gllmt! - Adds a waitUntil option to the RenderOptions so that adapters can forward runtime background-task hooks to Astro.
When provided by an adapter, runtime cache providers receive context.waitUntil in
CacheProvider.onRequest(), which allows background cache work such as stale-while-revalidate
without blocking the response. The Cloudflare adapter now forwards
ExecutionContext.waitUntil to this API.
#16290 a49637a Thanks @ViVaLaDaniel! - Ensures that server.allowedHosts (and vite.preview.allowedHosts) configuration is respected when using astro preview with the @astrojs/cloudflare adapter. This improves security by preventing DNS rebinding attacks when previewing Cloudflare builds locally.
