Angular core version 15.1.3 represents a minor update from the previous stable version 15.1.2, both maintaining the same fundamental structure as the core Angular framework. Developers relying on Angular's essential features will find the transition smooth. The dependencies remain consistent, with tslib staying at "^2.3.0", ensuring continued compatibility for TypeScript helpers. Similarly, the peer dependencies for rxjs ("^6.5.3 || ^7.4.0") and zone.js ("~0.11.4 || ~0.12.0") are unchanged, so no immediate updates are required in those areas.
The essence of Angular, its MIT license, repository location on GitHub, and authorship all remain the same and the general functionality is not affected. Crucially, though the change may seem small, the unpacked size of 15.1.3 has increased slightly to 18277762 bytes from 18277401 bytes indicating potential bug fixes and small adjustments within the library. While the file count of 284 remains the same, developers should investigate the changes for potential performance enhancements or addressing of reported issues present in 15.1.2. Version 15.1.3 was released on "2023-02-02T21:36:17.209Z", a week after version 15.1.2 which was released on "2023-01-25T16:52:23.128Z" which suggest the update was a quick response to fix some minor issues.
