Version Details and Security Vulnerabilities

Angular developers considering upgrading from version 13.4.0 to 14.0.0 of @angular/core will find a focused set of changes primarily centered around internal optimizations and modernization, though with potentially noticeable impacts. Both versions maintain identical dependencies on tslib and peer dependencies on rxjs and zone.js, suggesting API compatibility is largely preserved at this level. The key difference lies in the internal structure and size; version 14.0.0 features a significantly larger unpacked size of 19.2MB compared to 13.4.0's 12.8MB, seemingly coupled with one less file. Developers should anticipate a substantial build and potential runtime size impact after upgrading. Moreover, version 14.0.0 was released much earlier in June 2022, while version 13.4.0 was release in April 2023. This may mean that version 13.4.0 has improvements and fixes compared to the previous one. The shift implies substantial internal changes and potentially new features, improvements in AOT compilation, or reworked module structures within @angular/core. While the changelog would provide precise details, developers contemplating the upgrade should carefully assess this size increase against anticipated performance gains or new functionalities. The unchanged dependencies suggest migration efforts should be minimal, but thorough testing and bundle size analysis are crucial to ensure optimal application performance post-upgrade.
