This will ensure that GitHub Actions stay up to date. As the checkout action is currently out of date, Dependabot should open a PR to update it after this PR is merged.
* Add Ruby 3.1 to CI
Update Rubocop for recent Rubies
Disable Rubocop run for Rubies before Ruby 2.4
Quote '3.0' in the CI configuration to ensure it loads a 3.0.x Ruby
Set RUBYOPT="--disable_error_highlight" so Ruby 3.1 error matchers pass
* Add CHANGELOG.md entry
* Re-add deleted line from CHANGELOG.md
* Set minimum supported Ruby version to 2.4.
Remove a number of code bits designed to support Rubies below version 2.4
* Bump version. Remove unneeded require from Gemfile. Add require to spec/support file
Using YAML lists over pseudo-JSON lists makes for easier diffs. Breaking
blocks apart with an empty line helps readability. Avoiding strings
delimeters when you don't need them helps with readability. The name of
the workflow should describe its purpose. Multithreading bundle installs
leads to faster builds. And we need to update the badge to our new CI
location.
