Version Details and Security Vulnerabilities

Version 4.2.0 of @adobe/css-tools introduces some under-the-hood changes compared to version 4.1.0, but both versions maintain the core promise of providing a robust CSS parser and stringifier for JavaScript environments. Examining the package.json differences reveals that the primary changes are not within the core functionality exposed to users, but rather in the package's distribution metadata. Specifically, version 4.2.0 has an increased unpackedSize of 171213 bytes compared to 4.1.0's 155348, indicating potential changes in the compiled output or bundled assets. This increase in size might be related to internal optimizations, bug fixes, or updates to the build process that don't directly impact the API.

From a developer's perspective, both versions share an identical set of development dependencies used for building, testing, and developing the library. This consistent dependency structure suggests that the core development practices and testing methodologies have remained stable between releases. The library relies on tools like gts, jest, webpack, and typescript, indicating a modern TypeScript-based development workflow. Developers using either version can expect similar performance and compatibility with existing build pipelines. The only meaningful change is the release date, with the newer version being released a month later. Ultimately, the jump from 4.1.0 to 4.2.0 seems to represent a minor iteration or patch, any breaking changes are unlikely.
