k8s: Kubernetes v1.37: Memory QoS Graduates to Beta
Kubernetes Official Blog
2026-09-14
Kubernetes v1.37 makes Memory QoS Beta and turns it on by default, but it does not change runtime behavior unless you explicitly set throttling or reservation fields. The main config change is that `memoryThrottlingFactor` now defaults to `null`, so existing clusters will not start writing `memory.high` unless they already set it.
