UglifyJS version 3.13.9 represents a minor update over its predecessor, version 3.13.8, in the popular JavaScript minification toolkit. While the core functionality remains consistent – parsing, mangling, compressing, and beautifying JavaScript code – there are subtle differences that might interest developers. Notably, the unpacked size of version 3.13.9 is slightly larger, indicating potential refinements or additions to the codebase, although the file count remains the same at 20. Date related information shows that the release are slightly more than a week apart.
Both versions depend on the same set of development dependencies, acorn version ~8.2.1 and semver version ~6.3.0, suggesting stability in the underlying parser and version management tools. The consistent license (BSD-2-Clause), repository URL, and author information highlight the ongoing commitment to maintaining the project's core principles.
For developers considering an upgrade, the differences in unpacked size may warrant further investigation, particularly if file size is a critical concern. Checking the changelog or release notes on the UglifyJS GitHub repository is highly recommended to understand the specific changes, bug fixes, or performance improvements introduced in version 3.13.9. If no material bugfixes or performance improvements are available in this version an upgrade might not be needed at all. Overall, the transition from 3.13.8 to 3.13.9 should be seamless, but a quick review of the release notes will ensure optimal integration into existing workflows.
