These updated images are cumulative, incorporating security fixes from all Container-Optimized OS versions released since the previous GKE release. To identify the specific vulnerabilities that were resolved in each updated Container-Optimized OS image, see the **Security** release notes for that image. The following table includes links to the release notes for each updated Container-Optimized OS image: | GKE version | Container-Optimized OS version | Details | | ------------------- | ------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------- | | 1.30.14-gke.2250000 | cos-117-18613-534-36 | [cos-117-18613-534-36 release notes](https://cloud.google.com/container-optimized-os/docs/release-notes/m117#cos-117-18613-534-36%5F) | | 1.31.14-gke.1634000 | cos-117-18613-534-36 | [cos-117-18613-534-36 release notes](https://cloud.google.com/container-optimized-os/docs/release-notes/m117#cos-117-18613-534-36%5F) | | 1.32.13-gke.1147000 | cos-117-18613-534-24 | [cos-117-18613-534-24 release notes](https://cloud.google.com/container-optimized-os/docs/release-notes/m117#cos-117-18613-534-24%5F) | | 1.33.9-gke.1166000 | cos-121-18867-381-24 | [cos-121-18867-381-24 release notes](https://cloud.google.com/container-optimized-os/docs/release-notes/m121#cos-121-18867-381-24%5F) | ## Feature Feature To provide more controls over the control plane version upgrade, you can now do the following: * Configure a frequency of disruption from auto-upgrades by using the cluster disruption budget. For more information, see[Control the frequency of disruption from auto-upgrades](https://docs.cloud.google.com/kubernetes-engine/docs/how-to/cluster-disruption-budget). * Continue using an existing control plane patch for a longer period, which facilitates large-scale upgrade and downgrade operations. For more information, see[Patch version support](https://docs.cloud.google.com/kubernetes-engine/versioning#patch-version-support).
