Angular Compiler version 19.0.2 is a minor update to the core compilation library for Angular applications, succeeding version 19.0.1. Both versions share the same fundamental dependencies, including tslib for TypeScript helper functions and a peer dependency on @angular/core, ensuring compatibility and consistent functionality within the Angular ecosystem. The MIT license remains in place, guaranteeing open-source usage rights, and the source code continues to be managed in the packages/compiler directory of the main Angular GitHub repository.
A subtle but potentially important difference lies in the unpacked size of the distribution. Version 19.0.2 exhibits a slightly larger size of 4291132 bytes compared to 19.0.1's 4289641 bytes, indicating possible additions or modifications to the compiled code. While both versions contain the same number of files (6), this size difference hints at internal improvements, bug fixes, or potentially new features within the compiler itself. Developers should investigate the Angular changelog for more granularity on these changes.
The release date also provides context, with version 19.0.2 being released on December 4, 2024, subsequent to the November 26, 2024 release of version 19.0.1. This temporal separation suggests that the newer version incorporates any fixes or enhancements identified since the previous release. For developers using Angular, upgrading to the latest minor version (19.0.2) is generally recommended, as it delivers the most up-to-date and refined compilation capabilities.
