Underscore.js, a widely-used JavaScript library providing functional programming utilities, saw a minor version bump from 1.13.3 to 1.13.4. While the core functionality and developer experience likely remain consistent, examining the release data highlights subtle changes. Both versions share identical development dependencies, suggesting no significant shifts in the build or testing environment. This includes tools for code coverage (nyc), globbing files, documentation generation (docco), Git hooks (husky), testing frameworks (karma, qunit), linting (eslint), bundling (rollup), minification (terser), and cross-browser testing (karma-sauce-launcher).
The key difference lies in the subtle change of the 'dist' section of the package which indicates the size of the packed and unpacked library. Underscore 1.13.4 shows a slight increase in unpackedSize (901694 bytes) compared to version 1.13.3 (901498 bytes). This change, although small, signals potential bug fixes, performance improvements, or minor feature additions within the library's source code. Developers should note this that the archive includes a slightly different code and could be considered as preferable to use; this aspect also reflects on an updated releaseDate, with version 1.13.4 being released on June 2nd, 2022, after version 1.13.3 released on April 23rd, 2022. For developers using Underscore.js, upgrading to 1.13.4 is generally recommended to benefit from possible improvements.
