Version Details and Security Vulnerabilities

Angular core version 15.1.1 is a minor patch release subsequent to version 15.1.0, both iterations representing the core framework for building web applications with Angular. Key areas like dependencies and peer dependencies remain consistent between the versions, specifying compatibility with libraries such as tslib, rxjs, and zone.js. Both versions are licensed under the MIT license and are maintained within the Angular project's GitHub repository.

The noticeable variances between these releases lie in the dist object that describes the package's distribution files. The fileCount has decreased from 286 to 284 in the newer version and the unpacked size is slightly smaller, going from 18282488 bytes to 18277401 bytes. These changes reflects internal optimization and code reduction. More significantly, the Release date indicates that version 15.1.1 was published on January 18, 2023, approximately a week after version 15.1.0, which was released on January 10, 2023. For developers, the move from version 15.1.0 to 15.1.1 represents a small, incremental update. Given the nature of versioning, it is most likely adressing bug fixes and very minor improvements, without introducing breaking changes. It is advisable for developers using Angular 15.1.0 to update to version 15.1.1 to benefit from these under-the-hood improvements and ensure stability of their angular applications.
