Are those changes backwards compatible? If not, the merged changes should include an exclamation mark likefeat!: eslint 9 support to make sure the release has a proper version.

Ah yes, thanks for the reminder. It is currently breaking, with globals now requiring Node 18 (and I should update engines as well), though I could revert those changes if such a switch is not desired, as otherwise the changes should not be breaking. I would personally think it is reasonable to up the minimum version and use the latest version.

I've updated to indicate it is a breaking change, but the PR title doesn't accept the exclamation mark, so I just did it within the commit.

@brettz9 is this PR ready for review? it's still in draft

Yes, it's ready for review. I just put it as a draft because I didn't want to convey it was ready for a quick merge, as someone should at least confirm the spec:e2e tests (I have a spotty connection where I am so it may be that which is preventing me from completing and reviewing those tests.)

Published this to next tag. Please test and I can push to latest tag

npm i eslint-plugin-compat@next

Seems to be working for me!
Just keep in mind to check if it's breaking for eslint v8 users and publish as v6 maybe, not v5.1.0.

It should still work with ESLint 8 (and whatever earlier versions were still working before the changes--the peerDependencies go back a ways). But it is a breaking change due to the Node version bump.

Works for me also in both ESLint 8 and ESLint 9.

I do see this with yarn (4.3.1), but will ignore it. I just figured I would mention it...

 eslint is listed by your project with version 9.6.0 (pe4bd0), which doesn't satisfy what eslint-plugin-compat and other dependencies request (^8.0.0).

maybe missing a || ^9.0.0 somewhere? hmm it looks right in this MR...

lock file looks good too..not sure what is going on
