Angular core version 12.2.1 represents a minor update to the Angular framework, building upon the foundation established by version 12.2.0. Both versions, described as "Angular - the core framework," share a common dependency on tslib (version ^2.2.0) and peer dependencies on rxjs (version ^6.5.3 || ^7.0.0) and zone.js (version ~0.11.4), indicating continued compatibility with existing reactive programming and asynchronous task management patterns. Licensed under MIT and maintained within the Angular GitHub repository (packages/core), these versions reflect the ongoing evolution of the framework.
The key difference lies in the details of their distribution packages. While both have an identical file count of 489, version 12.2.1 exhibits a slightly larger unpacked size of 16,160,526 bytes, compared to 16,160,366 bytes in version 12.2.0. This suggests minor internal adjustments or bug fixes. The release date also marks a distinction, with version 12.2.1 being published on August 11, 2021, succeeding version 12.2.0 which was released a week earlier on August 4, 2021. For developers, this incremental update likely addresses specific issues identified in the earlier 12.2.0 release, potentially improving stability or performance. Users seeking the most up-to-date and refined experience should choose version 12.2.1. As a patch version, it often contains bug fixes, performance improvements, or minor updates without introducing breaking changes therefore the migration from 12.2.0 should be easy.
