ESLint v9.0.0: A retrospective

Published May 21

It's been over a year since ESLint v9.0.0 was released... What went well, what didn't, and what we've learned.

After 5 years in development, 9.0 "didn't work" and "broke the ecosystem". Why?

• Too many breaking changes
• Tooling first, documentation second
• Errors need context
• Ecosystem outreach needs improvement

Thanks!
