## Security Fixes

### Keeping your actions up to date with Dependabot

With Dependabot version updates, when Dependabot identifies an outdated
dependency, it raises a pull request to update the manifest to the
latest version of the dependency. This is recommended by GitHub as well
as The Open Source Security Foundation (OpenSSF).
