Kubernetes v1.35 introduces an opt-in feature for CSI drivers to receive service account tokens through a dedicated secrets field instead of the volume context. This change aims to improve security by preventing accidental logging of sensitive tokens and standardizing how they are handled. Drivers can opt-in at their own pace, ensuring backward compatibility.

Kubernetes v1.35 introduces workload aware scheduling, enhancing how multiple Pods are scheduled together. It features a new Workload API for defining scheduling requirements and supports gang scheduling to optimize resource use for large workloads. The update also includes opportunistic batching to speed up scheduling for identical Pods.
