Angular 18 introduces experimental zoneless change detection, offering improved performance, composability, and debugging. Angular.dev becomes the official documentation website, providing an enhanced user experience. Material 3 components, deferrable views, and built-in control flow are now stable, along with i18n support for server-side rendering hydration. Native async/await is available for zoneless apps, reducing bundle sizes and improving debugging. The event dispatch library from Google.com powers event replay in Angular, preserving user events during page loading. Angular DevTools provides improved debugging for hydration processes. All Angular Material and CDK components are now fully hydration compatible. Partial hydration is in development, enabling incremental hydration after server-side rendering. Zoneless change detection enhances composability for micro-frontends and interoperability with other frameworks. Deferrable views improve Core Web Vitals, while built-in control flow offers better performance and ergonomics.
