ESLint 9 is now stable

[nicolo-ribaudo]

I published @babel/eslint-parser@7.24.5-pre.1 and @babel/eslint-plugin@7.24.5-pre.1 (both tagged as next-eslint-9 on npm) from #16414. Please try them out and report any problems!

Whoops, my mistake 😅 I'll re-publish.

[nicolo-ribaudo]

Can you try again with @babel/eslint-parser@7.24.5-pre.2? and @babel/eslint-plugin@7.24.5-pre.1.

Can you try again with @babel/eslint-parser@7.24.5-pre.2? and @babel/eslint-plugin@7.24.5-pre.1.

Hi @nicolo-ribaudo installed @babel/eslint-parser@7.24.5-pre.2 with "eslint": "^9.1.1" and works like a charm!

@babel/eslint-plugin@7.24.5-pre.1 gives error:

npm ERR! Could not resolve dependency:
npm ERR! peer @babel/eslint-parser@"^7.11.0" from @babel/eslint-plugin@7.24.5-pre.1

tried installing @babel/eslint-plugin@7.24.5-pre.2, but no luck 😄
npm ERR! notarget No matching version found for @babel/eslint-plugin@7.24.5-pre.2

Thanks

The version range ^7.11.0 does not cover the pre-release versions such as 7.24.5-pre.1. From now on you can safely ignore this error - it will be resolved automatically when we release the patch version.

[nicolo-ribaudo]

I can release later today
