cssnano, a modular CSS minifier built upon the PostCSS ecosystem, has released version 7.1.1 following the earlier 7.1.0. Both versions maintain the core functionality of minifying CSS, leveraging PostCSS for advanced transformations and optimizations. A key difference lies in the updated dependencies. Version 7.1.1 updates cssnano-preset-default from version 7.0.8 to version 7.0.9, while the older version of the package had version 7.0.8 of that package. The cssnano-preset-default package provides a sensible default configuration for CSS minification, so users should review the changes in its patch release to understand changes in default behaviour. Both versions share the same development dependencies including autoprefixer, postcss, cssnano-preset-lite, cssnano-preset-advanced, same peer dependencies on postcss, and same number of files and unpacked size. The release date for version 7.1.1 is August 22, 2025 whereas the package 7.1.0 was released on July 14, 2025. Developers utilizing cssnano should assess the upgrade based on their reliance on the default preset and any specific configurations they may have in place. Given the minor version bump, changes are likely bug fixes or minor enhancements within the preset. It is recommended to review the changelog for cssnano-preset-default version 7.0.9 to ensure compatibility and desired minification behavior in their projects.
