 ### Versioning

 Generally, it is recommended to use the latest release of kube-state-metrics. If you run a very recent version of Kubernetes, you might want to use an unreleased version to have the full range of supported resources. If you run an older version of Kubernetes, you might need to run an older version in order to have full support for all resources. Be aware, that the maintainers will only support the latest release. Older versions might be supported by interested users of the community.
