A repository building released rubies to be used in GitHub Actions.
The action to use these prebuilt rubies is ruby/setup-ruby.
Please report issues to ruby/setup-ruby.
The latest release contains all built Rubies.
When making builds a different way, first create a new release and mark it as prerelease.
Then if it might cause breaking changes, open an issue on actions/virtual-environments with a description of the changes. This needs to be done 2 weeks prior to using the release.
Once it's ready, mark the release as non-prerelease and switch to it in ruby/setup-ruby.
