Next.js 16: Turbopack, React Compiler & Cache

A comprehensive guide to three major changes coming to Next.js 15+ and the anticipated Next.js 16: Turbopack moving toward becoming the default production bundler (replacing Webpack), the React Compiler graduating from experimental to built-in for automatic memoization, and a restructured opt-in caching layer using 'use cache', cacheLife(), and cacheTag() APIs. Covers migration checklists, before/after config examples, memoization refactoring patterns, and a step-by-step upgrade sequence including codemods and benchmarking guidance.
