eslint v9 support

[ljharb]

(see also #2478, #2223, #2036, #1834, #1447)

eslint v9 was released on 2024.04.05.

The current plan is, if possible, to release a new semver-minor of both configs, that supports 7 || 8 || 9.

Note that this is different from whether flat config is supported or not by these plugins, and from whether this project will convert to flat config.

The timeframe for eslint v9 support is "not as soon as you would like, but as soon as we can".
Please accept this, and please add no noise to this thread beyond emoji reactions - distractions won't help anyone get the work done any faster.

Please do not file additional issues and do not file pull requests attempting to add support - please, instead, continue to use eslint v8 until such time as our configs support v9.

Peer Dep eslint combined v7, v8, and v9 support released:

• eslint-plugin-import (PR)
  • flat config support (PR)
• eslint-find-rules
• update the base config
• publish the base config, semver-minor
• eslint-plugin-react
  • flat config support
• eslint-plugin-jsx-a11y (PR)
  • flat config support
• eslint-plugin-react-hooks
  • v9 support (PR)
  • flat config support (PR)
• update the main config
• publish the main config, semver-minor

@mamlzy yes, it's still being worked on.

Looking at the list of checks on this ticket, I found that eslint-find-rules has an open draft PR since October 7 but it seems to be sitting there waiting on a reviewer:

sarbbottam/eslint-find-rules#356

edit: reading it again, it appears to be a duplicate of sarbbottam/eslint-find-rules#353

Indeed, it's waiting on me to have time to test it.

2024 is almost over and our project is still waiting for you to upgrade to v9 supporting. :(

If you're so rushed about it, why don't you contribute? This project and its dependencies are all open source

At the top of this issue tracker it literally says don't contribute:

"Please do not file additional issues and do not file pull requests attempting to add support - please, instead, continue to use eslint v8 until such time as our configs support v9"

@trickpattyFH20 to be clear, that means "don't file pull requests to this repo" - when there's work to be done on other repos, please do contribute! however, at this point it's just waiting on me to have time to do some testing.
