Autoprefixer 10.3.4 represents a minor update to the popular CSS prefixing tool following version 10.3.3. Primarily, the core functionality remains consistent: parsing CSS and automatically adding vendor prefixes leveraging data from Can I Use to ensure cross-browser compatibility. Both iterations share identical dependencies, including colorette, fraction.js, browserslist, caniuse-lite, normalize-range, and postcss-value-parser, indicating no significant overhaul in the tool's underlying architecture or feature set. The peer dependency on postcss also remains unchanged, requiring version 8.1.0 or higher.
The key difference lies in the dist section, which reveals subtle variations in the unpacked size. Version 10.3.4 has an unpacked size of 225131 bytes, slightly larger than 10.3.3's 224991 bytes. While the fileCount remains constant at 83, the increased size may indicate minor bug fixes, performance enhancements, or updated data within the caniuse-lite database to reflect the latest browser support information. Developers should consider upgrading to 10.3.4 primarily to benefit from these potential improvements and ensure CSS is optimally prefixed for the widest range of browsers based on the most recent browser support data available. The update was released on September 2, 2021 whereas version 10.3.3 was released on August 26, 2021.
