UglifyJS version 3.13.10 represents a subtle but potentially important update to the JavaScript minification and compression toolkit, building upon the foundation of version 3.13.9. Both versions share the same core functionality as robust JavaScript parser, mangler, compressor, and beautifier, crucial for optimizing code for production environments. Key dependencies, acorn (~8.2.1) for parsing and semver (~6.3.0) for version management, remain consistent, indicating no major architectural shifts. The BSD-2-Clause license ensures freedom and flexibility for developers. Mihai Bazon continues to be listed as the author.
The primary difference lies within the "dist" section. Version 3.13.10 has a slightly larger unpacked size of 1,162,619 bytes compared to version 3.13.9's 1,155,633 bytes, which may imply minor code enhancements, bug fixes, or updates to the internal data structures that lead to the increase in size. While the fileCount remains at 20, the differences in packed size suggest internal modifications. Developers should evaluate update UglifyJS to version 3.13.10, released on June 27, 2021, versus version 3.13.9, released on June 4, 2021, by trying it on their specific code base to see if any improvements are achieved. It's typical to expect general refinement or targeted bugfixes.
