UglifyJS, a widely used JavaScript toolkit for parsing, mangling, compressing, and beautifying code, saw a release of version 3.15.4 following closely on the heels of version 3.15.3. Both versions share the same core functionality and development dependencies, relying on acorn version ~8.2.1 for parsing and semver version ~6.3.0 for semantic versioning. The project is licensed under the BSD-2-Clause license and maintained by Mihai Bazon.
While the core functionality remains consistent, a noteworthy difference appears in the dist object. Version 3.15.4 has an unpacked size of 1238049 bytes, slightly larger than version 3.15.3's 1235919 bytes. This suggests that version 3.15.4 might include minor bug fixes, performance improvements, or additions leading to the size increase. Developers should consider this potential change if file size is a critical factor in their deployment pipeline, even though the difference is relatively small.
The releases also differ in their release dates. Version 3.15.3 was released on March 10, 2022, while version 3.15.4 was released on April 9, 2022. This temporal proximity indicates active maintenance and potential resolution of recently discovered issues. Developers seeking the most up-to-date and potentially bug-free experience should favor version 3.15.4. For those already using 3.15.3, upgrading to 3.15.4 is advisable to benefit from any refinements made in the newer version. This upgrade ensures usage of the most recent stable release.
