Hey there, amazing developers! Welcome back to another episode of the Node.js podcast. I'm your host, and wow, what a fantastic Friday the 14th we have ahead of us! I hope you're settling in with your favorite beverage because we've got some really solid improvements to chat about today.

You know, sometimes the best days in open source aren't about flashy new features – they're about the careful, thoughtful work that makes everything more secure and polished. And that's exactly what we're seeing today with four quality pull requests that just landed.

Let's start with the most technical but honestly fascinating change from Filip Skokan, who goes by panva on GitHub. They've been doing incredible work on post-quantum cryptography support in Node.js, and this latest PR really shows their attention to security details.

Here's the story: Node.js has experimental support for these cutting-edge ML-KEM and ML-DSA algorithms – these are the cryptographic building blocks that'll help protect us in a world where quantum computers might break current encryption. But Filip noticed something important – when you're importing private keys in…

So Filip added validation that throws a…
