Astro 7.4 introduces `astro build --timings`, breaking down time spent rendering pages, running Vite plugins, processing Markdown, and transforming images. The release example shows how the report exposed sequential network requests and helped cut generation time for blog pages.

The release also separates image services for build and runtime, and adds `notFound()` for manually composed entrypoints. Parallel prerendering and custom redirect pages remain **experimental**; the former can increase memory use. One upgrade requirement to check: Astro now requires Node.js 22.22.0 or later.
