Nx 23 ships major performance improvements including 4x faster Nx Agents (12 min vs 48 min wall-clock) and 30% cost reduction versus GitHub Actions, plus a 7x memory reduction in the Nx daemon. The release introduces agentic migrations that combine deterministic generators with AI-driven steps for frameworks like Next.js 16, Nuxt 4, Vite 8, and Storybook 10. New features include OS-level task sandboxing for cache correctness, a spread token (`...`) for extending inherited targetDefaults, shell tab-completion, native Node.js TypeScript stripping, and V8 compile cache support. The `@nx/dotnet` plugin graduates to GA with full C#/F#/VB.NET support. Breaking changes include dropping Node 20, removing several deprecated generators and executors, and finalizing the Vitest split into its own `@nx/vitest` plugin.
