Angular developers should be aware of the subtle but important distinctions between @angular/compiler versions 19.1.4 and 19.1.5. Both versions share the same core description as the Angular compiler library, depend on tslib (version ^2.3.0), and are peer dependencies of @angular/core corresponding to their respective version numbers. This means that @angular/compiler 19.1.5 is designed to work with @angular/core 19.1.5, and similarly for version 19.1.4. Both versions are licensed under MIT and reside in the same repository within the Angular project on GitHub.
The key differences lie in their release date and unpacked size. Version 19.1.5 was released on February 6, 2025, while 19.1.4 was released on January 29, 2025. Although both versions contain 6 files after unpacking, version 19.1.5 is slightly larger, with an unpacked size of 4,272,551 bytes compared to 4,272,147 bytes for version 19.1.4. This size difference, although minor, suggests the inclusion of new features, bug fixes, or performance improvements in the newer version. Developers should always consult the official Angular changelog or release notes for a comprehensive list of changes between these versions to ensure they are leveraging the most up-to-date and potentially optimized compiler features for their Angular applications. Upgrading from 19.1.4 to 19.1.5 is generally recommended to benefit from these improvements, but testing is essential to confirm compatibility and avoid unexpected regressions.
