@jcfnomada Thanks for the tip. AwesomeAssertions provides some Renovate configuration that I should be able to directly use to replace FluentAssertions with AwesomeAssertions

{
  "packageRules": [
    {
      "matchPackageNames": ["FluentAssertions"],
      "replacementName": "AwesomeAssertions",
      "replacementVersion": "7.0.0"
    }
  ]
}

That said, AwesomeAssertions has nothing new and the author writes the following in the README

Please do not expect updates to this fork, as I cannot commit to maintaining it in the future. I will do my best to review and merge critical PRs if required and to release new versions of AwesomeAssertions as needed.

I'll try it out, or maybe I'll stay on FluentAssertions v7.x since there are still commitments to support it with Hotfixes.

I have also been toying with the idea of switching to Shoudly, but I don't see much gain in that either.
