I reviewed how our release of v9.0.0 in 2024 went, including what went well, what went wrong, and what we learned.

I'm an independent software engineer, coach, and author of more than 10 books on JavaScript and web development. I've been working on open source projects for almost 20 years. My first significant contributions were to the Yahoo! User Interface (YUI) library, where I wrote the project's testing framework and cookie utility. Over the years, I contributed to JSHint, co-created CSS Lint, and created ESLint, which is the de facto standard for JavaScript linting.
