+With each major, minor, or patch version release of {product-title}, two components of hosted control planes are released:
 
 * HyperShift Operator
-* `HostedCluster` and `NodePool` API resources
 * Command-line interface (CLI)
 
-The HyperShift Operator manages the lifecycle of hosted clusters that are represented by `HostedCluster` resources. The HyperShift Operator is released with each {product-title} release. Any HyperShift Operator that is released with a minor _n_ version of {product-title} must support _n_, _n-1_, and _n-2_ minor versions of {product-title}.
+The HyperShift Operator manages the lifecycle of hosted clusters that are represented by `HostedCluster` API resources. The HyperShift Operator is released with each {product-title} release. Any HyperShift Operator that is released with a minor version of {product-title} must work with all versions of {product-title} where hosted control planes are available.
 
 The CLI is a helper utility for development purposes. The CLI is released as part of any HyperShift Operator release. No compatibility policies are guaranteed.
 
 The API, `hypershift.openshift.io`, provides a way to create and manage lightweight, flexible, heterogeneous {product-title} clusters at scale. The API exposes two user-facing resources: `HostedCluster` and `NodePool`. A `HostedCluster` resource encapsulates the control plane and common data plane configuration. When you create a `HostedCluster` resource, you have a fully functional control plane with no attached nodes. A `NodePool` resource is a scalable set of worker nodes that is attached to a `HostedCluster` resource.
 
-The `HostedCluster` and `NodePool` resources are released with each {product-title} release. Any `HostedCluster` or `NodePool` resources that are released for a minor _n_ version of {product-title} must support _n_, _n-1_, and _n-2_ minor versions of {product-title}. The API version policy generally aligns with the link:https://kubernetes.io/docs/reference/using-api/#api-versioning[Kubernetes API versioning].
