- Upgrade to Vite 8, Rspack 2 (via Rsbuild) and unhead v3, delivering faster builds and enabling experimental SSR streaming.
- Add new composables and conventions: useLayout, enabled option for useFetch/useAsyncData, named views, import.meta.envName, and a stable error code system.
- Introduce optional prefetch preload hints and tracing channels, with breaking type changes in unhead v3 and potential Vite 8 compatibility concerns.
