Kubernetes 1.37 Coming Soon: HPA Scale-to-Zero, DRA Graduation to Stable, IPVS Mode Phased Out

Kubernetes 1.37 is scheduled for release on August 26, 2026, and the official Sneak Peek and enhancement tracker list 86 changes. This article focuses on three areas that require the most attention from operations teams: HPAScaleToZero has entered Beta and is enabled by default, allowing queue-based workloads to natively scale to zero; DRA device taint tolerance (KEP-5055) has reached GA, enabling GPU clusters to taint and evict pods based on specific devices; the kube-proxy IPVS mode has started the deprecation process, it will be disabled by default in 1.40 and completely removed in 1.43, so teams should migrate to nftables in advance. It also sorts out pre-upgrade check items such as metrics.k8s.io GA, containerd 2.0 and cgroup v2 upgrades.
