UglifyJS is a vital JavaScript toolkit renowned for its parsing, mangling, compression, and beautification capabilities. Comparing versions 3.13.2 and 3.13.1 reveals subtle but important differences. Both versions share the same core functionality, developer dependencies on Acorn (version ~7.1.0) and Semver (version ~6.3.0), and licensing under the BSD-2-Clause. They also draw from the same repository and maintain the same authorship by Mihai Bazon.
The key distinction lies in the dist section, specifically the unpackedSize. While both versions contain 20 files, version 3.13.2 boasts an unpacked size of 1106906 bytes compared to 3.13.1's 1102037 bytes. This suggests potential bug fixes, performance improvements, or minor feature additions in the newer version, resulting in a slightly larger footprint. Developers should consider this when disk space is a concern, though the difference is minimal. The release date confirms that version 3.13.2 (March 21, 2021) is the newer release compared to 3.13.1 (March 12, 2021), meaning users benefit from the latest enhancements. By upgrading, developers gain access to the most recent refinements within the UglifyJS library, potentially leading to a better overall experience.
