Node.js v20.19.6 (LTS) released
The Node.js team has released its latest long-term support version, 20.19.6 'Iron.' The LTS branch hosts this update, which aims to resolve certain issues while maintaining stability and security.
The release updated the root certificates. Node now also uses NSS 3.114, bringing you up-to-date with modern security standards for handling encrypted data securely right at the core level.
Beyond that security bit, several important dependencies got some attention too. Think of 'undici,' Node's own HTTP client, upgraded to version 6.22.0, or the 'uvwasi' component updated to 0.0.23. These are among the changes designed to improve performance and reliability.
Also noteworthy is an update to how Node handles HTTP/2, particularly fixing issues with ping buffer length mismatches. That should make web interactions smoother for many users out there.
And while all that's happening under the hood, the team didn't forget about things like clear documentation or everyday bugs. They've updated docs around verifying releases and refined clarity. Plus, many bug fixes rolled in, addressing superscript display quirks on Windows, improving devcontainer integration points, and generally making Node run a bit better.
This latest 'Iron' LTS version throws down another solid set of updates for the platform. For developers diving into or maintaining their Node.js projects, there's plenty here to keep you satisfied: more secure core handling, smarter HTTP code, updated tools, and just plain smoother operation in many cases.
