PostCSS Custom Properties, versions 12.1.0 and 12.1.1, are closely related iterations of a plugin designed to empower developers with the ability to leverage CSS Custom Properties Queries. Both versions share the same core functionality, allowing developers to enhance their stylesheets by using custom properties to query and modify CSS rules, making styles more dynamic and responsive. They both depend on postcss-value-parser and support environments with postcss version 8.3 or greater.
Specifically, version 12.1.1 is a patch release following 12.1.0, suggesting it addresses minor bugs, optimizations, or dependency updates without introducing significant new features or breaking changes. A key difference lies in the unpackedSize, with 12.1.1 at 33762 bytes, slightly larger than 12.1.0's 33691 bytes, possibly from bug fixes or small adjustments. From a developer's perspective, this patch offers increased stability and reliability in integrating Custom Properties Queries into existing PostCSS workflows. It includes tools for testing via postcss-tape and supports dependency management via postcss-import. Upgrading from 12.1.0 to 12.1.1 is recommended for all users to benefit from the latest improvements and refinements, leading to a smooth and maintainable CSS workflow. While both versions are under the MIT license and maintained within the csstools/postcss-plugins repository, version 12.1.1 represents the more up-to-date and potentially more robust option, and upgrading should be seamless.
