CSSO version 4.0.1 is a minor update to the CSS minifier, building upon the stable 4.0.0 release. Both versions offer robust CSS minification with structural optimizations, aiming to reduce CSS file sizes efficiently for faster website loading. A key difference lies in the updated dependency on css-tree, moving from version 1.0.0-alpha.36 in 4.0.0 to 1.0.0-alpha.37 in 4.0.1. This likely incorporates bug fixes and potentially new features or performance improvements within the css-tree parser, indirectly benefiting CSSO users.
For developers, the update should be seamless unless they are directly interacting with css-tree's API. Besides the mentioned dependency update, the core minification functionality remains consistent, preserving the structural optimization capabilities. The development environment remains largely unchanged, with identical tooling for testing, linting, and bundling like eslint, mocha, rollup and terser. The only other difference is in the source-map dependency version which moved from 0.5.6 to 0.6.1. This change might affect debugging workflows involving source maps. Version 4.0.1 was released shortly after 4.0.0, and the file sizes of the package are pretty similar, so it is most likely a bugfix release with minor improvements or fixes brought by the updated dependencies or generated source maps. Upgrading is recommended to leverage any potential enhancements.
