Is this the proper PR to subscribe to for getting updated about making this plugin compatible working with eslint v9? I'm asking because it's been in draft state since August. Anything I could potentially help with to get it into review state?

[G-Rath]

@niklaas this is good to go but currently a draft as it's branched off of #926 (which proves the plugin works with ESLint v9) and in turn that's branched off of #925 (which is the runtime fix required for the plugin to work with v9) - I've done them as dedicated PRs as I feel it's nice to have them in their own commits and released independently in case something comes up along the line.

While @Belco90 doesn't have to land my PRs, I suspect that he'll be happy with them so I think it's the one to subscribe to - alternatively you could subscribe to releases for this whole codebase since it's most likely the next release will include v9 support:
