Next.js 16 beta introduces Turbopack as the default bundler with 2-5x faster builds and up to 10x faster Fast Refresh. Key features include filesystem caching for Turbopack, stable React Compiler support for automatic memoization, enhanced routing with layout deduplication and incremental prefetching, and improved caching APIs with new updateTag() and refresh() functions. The release includes React 19.2 features like View Transitions and useEffectEvent(), removes deprecated features like AMP support and the next lint command, and requires async access to params, searchParams, cookies(), and headers(). Breaking changes include minimum Node.js 20.9+ requirement, new next/image security restrictions, and mandatory default.js files for parallel routes.
