Cssnano version 5.0.1 is a minor patch release over version 5.0.0 of this popular modular CSS minifier built atop the PostCSS ecosystem. Both versions share the same core description and maintain the same dependency on cosmiconfig, is-resolvable, and cssnano-preset-default. They also offer the same peer dependency for postcss and dev dependencies for postcss and autoprefixer, all at compatible versions. The license, repository information, author details, and funding links are identical across both releases.
The key difference lies in the removal of opencollective-postinstall as a direct dependency in version 5.0.1. This suggests a change in how the project handles Open Collective integration, perhaps moving it to a different mechanism or removing it entirely. Developers upgrading from 5.0.0 should be aware of this change, especially if they relied on opencollective-postinstall for any specific functionality. The unpacked size has also increased slightly from 33240 to 33532, but the file count stays the same. This suggest there's been changes mainly to the sources or added comments.
For developers using cssnano, these versions provide a robust solution for CSS minification, leveraging the power of PostCSS. The modular design lets you create custom minification pipelines, tailoring the optimization to your specific needs, while the defaults offer an out-of-the-box solution.
