@pirj I'm probably going to merge these 4 prs, they do this:

• Add Ruby 3.1
• Extract rubocop to its own job, we only really had it within the other builds as a "hangover" from Travis days where you couldn't specify multiple checks so easily, I don't think we need to check every ruby for rubocop compliance, this will make it easier to upgrade, its currently on Ruby 3.
• Skip the rspec-rails cross build on Ruby 3.1 until 6.1 supports it or we swap the default build to 7.

The only remaining "consistent" failure is ruby-head, the windows builds do just randomly segfault sometimes.

we need to check every ruby for rubocop compliance

That's fine. It's getting late, and I'm struggling to come up with an example code that RuboCop would detect on a certain Ruby version as incompatible, while specs would pass. And this will really ease up RuboCop version update (cc @petergoldstein)

Skip the rspec-rails cross build on Ruby 3.1 until 6.1 supports it or we swap the default build to 7

rspec/rspec-rails#2553 fixes net-* dependency problem.
We still probably have to switch ~> 6.0.0 to ~> 6.1.0 in when nil, false, "" in Gemfile-rails-dependencies.

It didn't.

Let's merge those 4 PRs and get this problem out of the way 👍
