Angular developers will find the transition from @angular/compiler version 9.1.4 to 9.1.5 a relatively minor update, primarily focusing on internal refinements and bug fixes rather than groundbreaking new features. Both versions share identical characteristics in terms of their core purpose: providing the essential Angular compiler library that translates Angular templates and code into efficient JavaScript instructions browsers can understand. The package descriptions, peer dependencies on tslib version ^1.10.0, licensing under MIT, the location of the source code within the Angular repository, and even the author remain unchanged. Furthermore, the crucial fileCount and unpackedSize of the distributed packages are also identical, suggesting no significant addition or reduction in the scope of the library. The primary difference lies in the releaseDate. Version 9.1.5 was released on May 7th, 2020, a little over a week after version 9.1.4, released on April 29th, 2020. This short interval strongly indicates that 9.1.5 is likely a patch release addressing specific issues identified in 9.1.4. Developers should consult the official Angular changelog for detailed specifics on these fixes. If 9.1.4 compiles for all your environments, and works properly in all your targeted browsers, then no upgrade is necessary. Developers experiencing very specific or unusual scenarios that were not covered in the testing or evaluation of 9.1.4 should consider upgrading to 9.1.5.
