Async is a popular JavaScript library designed to simplify working with asynchronous code, particularly in Node.js environments. Versions 0.1.20 and 0.1.21 share the same core purpose: providing higher-order functions and patterns to manage asynchronous operations effectively. Both versions boast no mandatory dependencies, making integration into existing projects straightforward. They also share the same development dependencies: nodelint, nodeunit, and uglify-js, employed for code quality and testing. Author remains Caolan McMahon. The repository is consistently located at the same GitHub URL.
The most notable difference between version 0.1.20 and 0.1.21 lies in that the release dates are different. Version 0.1.21 was released on May 24, 2012, slightly after version 0.1.20. While the change appears minor, developers should consider that even small version bumps can include bug fixes, performance improvements, or subtle API adjustments. Users should migrate using a new version. Developers are advised to consult the release notes or commit history on GitHub between versions 0.1.20 and 0.1.21 for a detailed understanding of the specific changes implemented. Accessing the tarball distribution is also a key feature for both versions provided by public registry. Although not explicitly stated, such changes often stem from addressing issues found in the previous release, thus warranting an upgrade.
