UglifyJS version 3.13.1 is a minor release update to the popular JavaScript parser, mangler, compressor, and beautifier toolkit, building upon the foundation laid by version 3.13.0. Both versions maintain the same core functionality: parsing, mangling, compressing, and beautifying JavaScript code. They share identical developer dependencies on acorn (version ~7.1.0) and semver (version ~6.3.0), ensuring consistent parsing and semantic versioning capabilities. The licensing remains BSD-2-Clause, and the repository details and author information are also unchanged, indicating a continuation of the project's open-source nature and leadership.
The key difference lies in the dist section. Version 3.13.1 shows a slightly larger unpacked size of 1,102,037 bytes compared to version 3.13.0's 1,095,792 bytes. This suggests that bug fixes, minor feature enhancements, or adjustments to existing compression algorithms were implemented to refine the overall performance or stability. The release date also reflects this update, with version 3.13.1 being published on March 12, 2021, subsequent to version 3.13.0's release on March 1, 2021. For developers, this signifies a potentially more polished iteration, likely containing valuable refinements without introducing breaking changes. Upgrading to version 3.13.1 should be considered a safe and beneficial step to ensure optimal performance and the latest bug fixes in JavaScript minification and code optimization.
