Next.js gives you the building blocks to create full-stack web applications - routing, rendering, data fetching, bundling, and more, built on top of React.
npx create-next-app@latest`fetch` requests are no longer cached by default
Every `fetch` call now opts out of the Data Cache unless you explicitly pass `{ cache: "force-cache" }` - update any code relying on the previous implicit caching.
Node.js 20.9+ required
Next.js 16 drops support for Node.js versions older than 20.9 - upgrade your runtime before updating.
Next.js 16 builds on the App Router with a more predictable caching model, a faster Turbopack-based production build, and continued investment in Server Actions and partial prerendering for mixed static/dynamic pages.
