Version Details and Security Vulnerabilities

@angular/common version 20.1.1 represents a minor update to the widely used Angular package, succeeding version 20.1.0. Both versions offer essential directives and services crucial for building Angular applications, sharing a common base feature set. Developers already familiar with the prior version will find a mostly seamless transition. Key dependencies like tslib remain consistent, ensuring compatibility with existing TypeScript setups. The peer dependencies highlight the expected versions of rxjs and @angular/core, crucial for maintaining a compatible Angular ecosystem. Notably, both versions maintain the same file count, suggesting no significant additions or removals in terms of files. However, there is a tiny increase in unpackedSize from 8373295 to 8373296 which will probably be due to some minor code changes.

The release date distinguishes the updates, with version 20.1.1 being released on July 16, 2025, approximately a week after version 20.1.0 which was released on July 9, 2025. This suggests a quick follow-up, possibly addressing bug fixes or minor enhancements identified shortly after the initial 20.1.0 release. For developers, upgrading to 20.1.1 is advisable to benefit from the latest refinements and stability improvements. Given the minor version bump, breaking changes are unlikely, minimizing disruption during the update process, but it's always good practice to check the Angular changelog to observe the real changes between versions.
