## AI overview

Next.js 16.3 improves the Turbopack bundler with lower development memory usage, persistent filesystem caching for faster builds, experimental Rust React Compiler support, API support, and faster hot module replacement and development startup. Memory-cache eviction, enabled by default with the development filesystem cache, helps prevent unbounded memory growth during long development sessions.
