Version Details and Security Vulnerabilities

Express-ntlm is a valuable piece of middleware for Node.js developers leveraging the Express framework and requiring NTLM authentication in their applications. Versions 2.1.3 and 2.1.4 offer a simple way to integrate NTLM authentication, allowing applications to authenticate users against Windows domains or systems employing NTLM. Both versions share a similar foundation, depending on the async and underscore libraries for asynchronous operations and utility functions respectively, and are compatible with Express versions 4.10.4 and above. This compatibility ensures a degree of stability when integrating this middleware into existing Express-based applications. The core offering of easy NTLM authentication remains consistent between the two versions. Examining the data you gave me doesn't show any functional differences. The primary distinction lies in the release date. Version 2.1.4 came out on April 10, 2015, a few days after version 2.1.3 released on April 7, 2015. While the change log isn't provided, this timeframe suggests that version 2.1.4 likely includes bug fixes or minor improvements addressed since version 2.1.3. Security conscious developers should always choose the later version. Both versions continue to be licensed under the BSD-2-Clause license, granting developers the freedom to use, modify and distribute the software as they see fit.
