- The `TopologyAwareHints` feature gate is now enabled by default. This will allow users to opt-in to Topology Aware Hints by setting the `service.kubernetes.io/topology-aware-hints` on a Service. This will not affect any Services without that annotation set. ([#108747](https://github.com/kubernetes/kubernetes/pull/108747), [@robscott](https://github.com/robscott))
