BREAKING CHANGES

• VitePress now uses Vite 8. If you are using Vite plugins in your config, please check the Vite 8 migration guide for any breaking changes that may affect you.
• Node 20 support is dropped. v22 or higher is needed.
• scrollOffset from config is removed. Users wanting to customize scroll offset should customize scroll-margin-top via CSS instead. smoothScroll support from router.go is also removed as it didn't work as expected for most users. Users wanting smooth scrolling should set scroll-behavior: smooth in CSS, ideally inside a @media (prefers-reduced-motion: no-preference) block.
