Does it also mean that we should bump the minimum required version? The AllowedPatterns is available since 1.28 and we already depend on 1.31, but if deprecation is broken, perhaps we should wait for the next release and also add dependency on it?

Yes. That is the recognition. https://github.com/rubocop/rubocop/pull/10831 has not been released yet, so it looks like we will have to wait for the next release.

But it's not released yet. This is why CI / spec Ruby 2.7 (edge) (rubocop master) passes, but other builds don't.

Let's wait for the fix to be released and bump the dependency.

Now we can incorporate this change:
