Angular 20 is a major release focused on performance, streamlined APIs, modern tooling, and enhanced developer productivity. Key updates include stabilized APIs for signal-based reactivity, further advancements in zoneless change detection (now in developer preview), and important improvements to server-side rendering and hydration for faster load times and better SEO. Several deprecations were introduced, most notably for the old structural directives (ngIf, ngFor, and ngSwitch) in favor of the more modern control flow syntax, with complete removal possible in future versions.

In templates, new operators and features are now supported: exponentiation (**), tagged template literals, void, and the in operator, enabling more expressive, modern code. Angular 20 also adds new diagnostics and error-handling options (such as provideBrowserGlobalErrorListeners) for more robust apps.

A major tooling shift is the transition to the @angular/build package, reducing dependency size and simplifying builds by removing Webpack-related packages. The Angular CLI now includes migration help and prompts to enable zoneless change detection, making new projects lighter and modern out of the box.

Dynamic component creation supports new options for bindings, directives, and event outputs, improving flexibility in UI composition. The router now allows resolvers to read parent route data, making data flows more intuitive. Overall, Angular 20 makes substantial progress toward a faster, simpler, and more maintainable framework, encouraging upgrades for continued support and access to these improvements.

Experimental new features under prototyping include signal-based forms (potentially offering a new model beyond reactive and template forms) and selectorless components (import and use components or pipes by class name, avoiding explicit selectors in templates), though these are not yet available for production use.
