 ## Schedule
 
-Cluster Autoscaler releases new minor versions shortly after OSS Kubernetes release
-and patches for versions corresponding to currently
-supported [Kubernetes versions](https://kubernetes.io/releases/) on a roughly 2
-month cadence. Currently planned schedule is below. Please note that target
-dates listed below are approximate and we expect up to a week difference between
-target ETA and the actual releases.

+Cluster Autoscaler synchronizes its releases with the [Kubernetes release schedule](https://kubernetes.io/releases/).
+
+For Cluster Autoscaler releases of new minor versions, expect a release date of up to
+one month after the corresponding Kubernetes release. This is due the fact that upstream
+integrations of Kubernetes into Cluster Autoscaler can't be finalized until the Kubernetes
+release is official, and the time required to test and validate those integrations.
+
+Cluster Autoscaler will also release patch versions in accordance with Kubernetes patch
+releases to ensure rapid integration of upstream Kubernetes fixes. The overhead to integrate
+and validate Kubernetes patch releases is less costly, and thus the Cluster Autoscaler
+release date should follow the corresponding Kubernetes release by no more than 1-2 weeks.
+
+Bug fixes and Cloud Provider features to Cluster Autoscaler itself will be continually
+backported into the supported release branches (n - 3, where n is the latest release).
+Backporting into older release branches can be requested as an exception by filing an issue
+and bringing the request [to the official SIG Autoscaling Community](https://github.com/kubernetes/community/blob/master/sig-autoscaling/README.md).
+
+Finally, additional Cluster Autoscaler patch releases may happen outside of the above schedule
+in case of critical bugs or vulnerabilities.
+
+In summary, users should not be guided by a strict patch version equivalency between Kubernetes
+and Cluster Autoscaler (for example, there is no strict requirement to use Cluster Autoscaler v1.34.1 w/ a Kubernetes v1.34.1 cluster). Rather, we recommend that users always use the _latest_
+Cluster Autoscaler release that corresponds to the minor version of Kubernetes that their cluster
+is running.
+
+For example, if the latest (hypothetical) Cluster Autoscaler releases are
+`v1.100.1`, `v1.99.5`, `v1.98.10`, and `v1.97.16`, any of the below scenarios follows the recommended guidance:
+
+| Kubernetes Version  | CA Version               |
+|---------------------|--------------------------|
+| 1.100.0             | 1.100.1                  |
+| 1.99.4              | 1.99.5                   |
+| 1.98.4              | 1.98.10                  |
+| 1.97.16             | 1.97.16                  |
