Version Details and Security Vulnerabilities

Angular Common version 20.1.4 is a minor update to the core Angular library providing essential directives and services for building web applications. Compared to the previous stable version, 20.1.3, the key changes primarily involve internal improvements and bug fixes, reflected in the slight increase in unpacked size from 8374146 to 8374720. Both versions share the same dependencies, relying on tslib for TypeScript helper functions and peer dependencies on rxjs (versions 6.5.3 or 7.4.0 and later) and @angular/core to ensure compatibility.

The upgrade from 20.1.3 to 20.1.4 is unlikely to introduce breaking changes. However, developers should review the Angular changelog for this release to understand any specific bug fixes or minor behavioral adjustments that could impact their applications. Both versions remains under the MIT license and the consistent file count suggests structural element were untouched. The release date difference between versions, approximately one week, could mean that this patch fixed some blocking issue in version 20.1.3. When upgrading, developers should ensure their projects meet the peer dependency requirements, particularly regarding RxJS and Angular Core. The rxjs dependency dictates the handling of asynchronous operations and data streams, a fundamental aspect of Angular development. Version 20.1.4 published on July 31, 2025 builds upon the robust foundation of Angular Common, aiming to provide a more stable and refined experience.
