UglifyJS version 3.13.7 represents a minor point release over the preceding stable version, 3.13.6, in this well-established JavaScript minification toolkit. Both versions offer core functionality for parsing, mangling, and compressing JavaScript code, crucial for optimizing web performance by reducing file sizes. Key aspects, such as the supported JavaScript syntax (leveraging acorn), the developer's licensing under BSD-2-Clause and repository on GitHub, remain consistent between the two. The core development dependencies also remain constant.
However, developers will see subtle but potentially important distinctions. The unpacked size of version 3.13.7 is slightly larger (1,147,329 bytes compared to 1,144,932 bytes in 3.13.6), indicating minor additions, refactoring, or bug fixes within the codebase. More definitively, the release date of 3.13.7 is May 18, 2021, a week later than version 3.13.6 that was released on May 10, 2021 suggesting a bug fix or minor feature was released.
While specific changelogs aren't provided in this data, developers should strongly consider upgrading to 3.13.7 for the latest stability and security enhancements. As with any minor release, checking the official UglifyJS repository or changelogs for detailed fixes and improvements is highly recommended before upgrading. Ultimately, sticking with the newest version ensures the most up-to-date and reliable JavaScript minification experience for both development and production environments. It is important to highlight there are no major dependency bumps, so the migration from version 3.13.6 to 3.13.7 should be seamless.
