Version Details and Security Vulnerabilities

The Angular compiler library @angular/compiler plays a crucial role in transforming Angular templates and TypeScript code into efficient JavaScript code that browsers can understand. Comparing versions 9.1.3 and 9.1.4 reveals minimal differences in core metadata, suggesting a patch release primarily focused on bug fixes and performance improvements rather than introducing major new features. Both versions share identical peer dependencies, requiring tslib version ^1.10.0, ensuring compatibility within the Angular ecosystem. The file count (598) and unpacked size (29125052 bytes) remain constant, further indicating a focus on internal refinements. The most notable difference lies in the release date: version 9.1.4 was published on April 29, 2020, a week after version 9.1.3 (April 22, 2020).

For developers using @angular/compiler, this implies that upgrading from 9.1.3 to 9.1.4 should be a relatively safe and straightforward process, providing potential benefits from bug fixes and performance optimizations without introducing breaking changes. While the specific nature of these improvements isn't evident from the provided data, staying up-to-date with patch releases is generally recommended for stability and reliability. Developers should consult the official Angular changelog and release notes for a comprehensive list of changes included in the 9.1.4 release to fully understand its impact on their projects.
