- 5.1.3 got broken down into 5.1.3.1 and 5.1.3.2
- 5.1.6 got broken down into 5.1.6.1 and 5.1.6.2
- version was set to cis-1.9
- node.yaml master.yaml controlplane.yaml etcd.yaml
- version was set to cis-1.9
* Adapt master.yaml
- Expand 1.1.13/1.1.14 checks by adding super-admin.conf to the permission and ownership verification
- Remove 1.2.12 Ensure that the admission control plugin SecurityContextDeny is set if PodSecurityPolicy is not used (Manual)
- Adjust numbering from 1.2.12 to 1.2.29
* Adjust policies.yaml
- Check 5.2.3 to 5.2.9 Title Automated to Manual

* Adjust policies 5.1.3 and 5.1.6
- Merge 5.1.3.1 and 5.1.3.2 into 5.1.3 (use role_is_compliant and clusterrole_is_compliant)
- Remove 5.1.6.1 and promote 5.1.6.2 to 5.1.6 since it natively covered 5.1.6.1 artifacts
* Add kubectl dependency and update publish
- Download kubectl (build stage) based on version and architecture
- Add binary checksum verification
- Use go env GOARCH for ARCH
