The npm package autoprefixer, designed to parse CSS and automatically add vendor prefixes based on Can I Use data, saw a version bump from 0.8.20130923 to 0.8.20131001 in late 2013. While both versions share the same core functionality and dependencies like css-parse and css-stringify for CSS handling, and development dependencies for testing and building with tools like mocha, rework, stylus, fs-extra, component and coffee-script, a subtle yet crucial difference lies in the version of stylus. The older version relies on stylus version 0.37.0, while the newer iteration utilizes stylus version 0.38.0.
This seemingly minor update could introduce changes in how Stylus interacts with Autoprefixer, potentially affecting the CSS parsing or prefixing behavior within a Stylus workflow. Developers using Stylus for CSS pre-processing should be mindful of this version jump when upgrading Autoprefixer. Although the changelog may be minor, keeping dependencies align properly can prevent unexpected issues. The package, authored by Andrey Sitnik and licensed under LGPL 3, remains a valuable tool for front-end developers aiming for cross-browser compatibility without manually managing vendor prefixes. Both versions are available on the npm registry, downloadable via their respective tarball URLs. The relatively short timeframe between releases suggests a quick patch.
