- Introduced experimental `advancedRouting` option with `src/app.ts` entrypoint, offering custom request pipelines via `astro/fetch` or `astro/hono`.
- Added `image.dangerouslyProcessSVG` flag, disabling SVG rasterization by default for security; enabling it restores previous behavior (breaking change).
- Enabled handling of up to 10 redirects in remote image optimization, now emitting clear errors for unsafe redirects, and fixed several bugs (CSP directive duplication, boolean array coercion, SSR logger crash).
