Angular Compiler version 13.2.1 represents a minor update to the Angular compiler library, building upon the foundation laid by version 13.2.0. Both versions share the same core functionality as the Angular compiler, responsible for transforming Angular templates and TypeScript code into efficient JavaScript instructions that browsers can execute. Key features like Ahead-of-Time (AOT) compilation, which improves application startup performance and security, remain central to both versions, alongside support for incremental compilation.
The primary distinction between the two releases lies in subtle refinements and potential bug fixes implemented in version 13.2.1. Developers upgrading from 13.2.0 might anticipate improvements in stability, performance enhancements, or resolutions to specific edge-case scenarios encountered during compilation. Although the dependency on tslib remains consistent at "^2.3.0" in both versions (ensuring compatibility with TypeScript helper functions), there are differences in the unpacked size and the number of files included in the distribution. Version 13.2.1 has a smaller unpacked size (8766933 bytes vs 8805365 bytes) and fewer files (219 vs 221) suggesting that some optimizations were applied. The newer version was also released on 2022-02-02, while the previous one was on 2022-01-26. Developers are encouraged to review the official Angular changelog for a comprehensive list of resolved issues and specific improvements introduced in version 13.2.1.
