# Checklist for submitter - [X] Changes file added for user-visible changes in `changes/`, `orbit/changes/` or `ee/fleetd-chrome/changes`. See [Changes files](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/guides/committing-changes.md#changes-files) for more information. - [X] Added/updated automated tests - [X] Manual QA for all new/changed functionality ## Details This PR updates the Open Policy Agent (github.com/open-policy-agent/opa) to version 1.4.2, and does the necessary test updates to handle the indirect upgrade of Viper (which no longer supports YAML 1.1). Once this is done we can also [upgrade NFPM](https://github.com/fleetdm/fleet). I chose not to do that in this PR to keep it to one change at a time.
