Next.js 16.3 has shipped with several notable improvements. Instant Navigation introduces a cacheComponents option so Server Component pages either stream with loaders or serve cached content, delivering an SPA-like feel. AI tooling gets a boost with officially maintained agent skill sets and an 'Instant Insights' feature that detects caching errors and generates prompts for agents to fix them. The dev server now uses 90% less memory, integrates TypeScript 7 for faster type-checking, and ships the latest Turbopack with experimental support for the Rust-based React compiler. The release also marks the return of former React core team members Dan and Pete.
