The autoprefixer package saw a minor update between version 0.8.20131209 and 0.8.20131213. Both versions are focused on automatically adding vendor prefixes to CSS rules, leveraging data from the "Can I Use" website to ensure cross-browser compatibility. This capability is crucial for front-end developers aiming to support a wide range of browsers without manually managing individual vendor prefixes. The core functionality remains the same, signified by identical dependencies on css-parse and css-stringify, libraries essential for CSS parsing and stringification.
The key difference lies in the stylus devDependency, upgraded from version 0.41.0 to 0.41.3 in the newer release. While seemingly a small change, this could potentially include bug fixes, performance improvements, or even new features within the Stylus CSS preprocessor integration. Given that Stylus is used for development purposes (as a devDependency), this update likely impacts the development workflow of those contributing to Autoprefixer itself, or those using Autoprefixer's build process within a Stylus environment. Developers relying on Autoprefixer for their CSS prefixing needs will likely experience a very similar result with either version, though the newer one incorporates enhancements specific to its Stylus development tooling. As it is a patch version upgrade, it is expected to include fixes and minor features, without breaking changes.
