DRA device taints and tolerations (KEP-5055). Dynamic Resource Allocation, or DRA, is how Kubernetes assigns hardware like GPUs to workloads. This feature, reaching Stable in 1.37, lets Kubernetes mark a broken or degraded device so it will not be handed to new workloads, similar to how a bad node can already be marked off-limits today. Administrators can also flag devices for exclusion based on criteria such as which driver manages them. Grunert said the feature lets degraded hardware be drained using the familiar node taint model.
Kubernetes improves networking
Kubernetes 1.37 continues moving cluster networking away from IPVS and iptables toward nftables, the newer approach built into the Linux kernel.
The kube-proxy component, which is the service that routes traffic to Kubernetes Services, has supported IPVS as an alternative to iptables since Kubernetes 1.8, but IPVS has relied on iptables underneath. That dependency is one reason Kubernetes is deprecating IPVS mode in favor of nftables
