Maybe Reline can also adopt the ruby-versions workflow like IRB did? And with Ruby 3.3's change on readline, we'll need to tweak the matrix a bit too.

Thank you for your sharing. I've updated.

NOTE: readline mswin windows-latest fails in CI. Because the installation of io-console is failing. I have created a PR that solves this problem. ruby/io-console#65

Thank you for the investigation and the fix! Since the PR has been merged, do you think we can point io-console to the GH source in Gemfile atm to workaround the issue?

@st0012
I added gem 'io-console', github: 'ruby/io-console' to Gemfile.
readline mswin windows-latest has passed, but other tests have failed. Unfortunately, we were unable to workaround it. https://github.com/ruby/reline/actions/runs/7411571609

I have requested a release of the io-console, but until then it will remain as is.

Ok, I think we can merge it first and wait for the release 👍
