About Angular 21

Angular 21 has transitioned into security-only maintenance since May 19, 2026. This means it still receives critical security patches, but no new features, performance improvements, or non-critical bug fixes will be backported. It remains a safe choice for production systems that cannot upgrade immediately, but you should begin planning your migration path. With 349 days until end of life, the window for a controlled, well-tested upgrade is narrowing.
