Kubernetes 1.37 (scheduled for August 26) introduces 22 new alpha features. Key highlights include: Pod-Level Checkpoint/Restore using CRIU for snapshotting entire Pods; multiple DRA enhancements (optional node preparation, device compatibility groups, standardized numaNode attribute, derived attributes for flexible hardware binding); CompositePodGroup API for hierarchical multi-level gang scheduling; nftables becoming the default kube-proxy backend; scheduler preemption for in-place Pod resize; TLS support for gRPC probes; HTTP/2 cleartext container probes; bind mount options (noexec, nosuid, nodev) for volume security; topology support for VolumeSnapshots; Volume Health Monitor via new CSI RPC calls; Recreate update strategy for StatefulSets; and internal API type elimination for significant performance gains. Notable non-alpha promotions include Kubelet-in-UserNS reaching Beta and KYAML becoming stable.
