Thanks Nick for your work. I updated it to latest rails and ruby and tests are running OK.

Hi,

Thanks for updating these, question for you:

• Do you have a large Rails app running in production with Ruby 3.1.0?

Here's a couple of change requests:

• Amend the commit message to "Update Ruby to 3.1.0 and Rails to 7.0.1"
• Update text references to Rails 7.0.1 and Ruby 3.1.0 in the README file near the top by "This app is using..."
• Update the versions in the CHANGELOG under the Unreleased section (languages and services + back-end dependencies)
• Update config/environments/test.rb with the change proposed by https://railsdiff.org/7.0.0/7.0.1

For the last one, that's the updated version of the file if you were to generate a new Rails 7.0.1 app. It's just adding a period at the end of the comment to match the other comments.

Just following up. Would like you make those edits and force push the changes?

I tend to do weekly updates for packages, services, etc. and it would be nice to bump these.

Hi,

While I do appreciate the PR, you kind of went MIA. My weekly update process ended up updating Rails to 7.0.1 and Ruby 3.1.0.
