The autoprefixer npm package automatically adds vendor prefixes to CSS rules, ensuring compatibility across different browsers and their versions. This eliminates the tedious manual process of adding prefixes like -webkit-, -moz-, -ms-, and -o-, simplifying CSS authoring and keeping stylesheets clean. Version 0.4.20130528, released on May 27, 2013, is a minor update from the previous stable version 0.4.20130524, released just a few days earlier on May 23, 2013.
Both versions rely on the "Can I Use" database to determine which prefixes are necessary for various CSS properties and values, ensuring that only the required prefixes are added, keeping stylesheets efficient. They share the same core functionality, using rework as a dependency for CSS parsing and manipulation. The developer dependencies for testing (mocha, sinon, should, component) and code formatting (js-beautify, coffee-script) are also largely the same. A key difference lies in the js-beautify version, which updated from version 1.3.2 to 1.3.3 between the releases. This suggests a minor fix or enhancement in the code formatting process.
For developers, these versions of autoprefixer provide a reliable solution for automating vendor prefix management. While the changes between these specific versions are relatively small, using the latest (in this case, 0.4.20130528) is generally recommended to benefit from any bug fixes or minor improvements, regardless of their size.
