* Bottlerocket v1.68.1 applies to Kubernetes versions 1.31 through 1.35. Kubernetes versions 1.29 and 1.30 remain on Bottlerocket v1.54.0.
* Starting with EKS-A minor release v0.25.0, the bundled Kubernetes Image Builder will no longer support Ubuntu 20.04 LTS builds, as Ubuntu 20.04 LTS Standard Support has ended, and the upstream Kubernetes Image Builder no longer supports Ubuntu 20.04 LTS.
* RHEL 8's kernel version (4.18) is not supported by kubeadm for Kubernetes versions 1.32 and above (see Kubernetes GitHub issue #129462). As a result, EKS Anywhere does not support using RHEL 8 as the node operating system for Kubernetes versions 1.32 and above.
