Version Details and Security Vulnerabilities

Angular Core version 13.1.2 represents a minor patch release over the preceding stable version 13.1.1. Both versions represent the core of the Angular framework, offering developers the foundational building blocks for creating dynamic web applications. Key elements such as dependency injection, change detection, and component architecture remain consistent.

Developers should observe that while the core functionality remains the same, there are subtle differences detectable through the package's metadata. For example, the fileCount in the distribution package has slightly decreased from 332 to 331, suggesting optimization or removal of a minor file. Similarly, the unpackedSize went down slightly, from 12660300 bytes to 12653206 bytes, which may indicate minor code optimizations or size improvements. These changes, although seemingly small, can contribute to a more streamlined and efficient application.

Both versions share the same dependencies, requiring tslib version 2.3.0 or higher. The peer dependencies also remain identical, demanding either RxJS version 6.5.3 or a version within the 7.4.0 range, along with Zone.js version 0.11.4. Thus, upgrading from 13.1.1 to 13.1.2 should not introduce breaking changes related to these shared dependencies. The MIT license, author ("angular"), and repository details also remain unchanged. Released in January 2022, version 13.1.2 arrives approximately a month after 13.1.1, suggesting a focus on bug fixes or minor enhancements identified after the initial release.
