 * ## Cache Optimization
 *
 * To measure cache effectiveness, this class tracks three statistics:
 *
 *  * **[Request Count:][requestCount]** the number of HTTP requests issued since this cache was
 *    created.

You could put an **arbitrary number** to target, for example, something **between 50% to 90%** of resource utilization. The point is that those are probably the main things you will want to measure and use to tweak your deployments.

- Enable the feature gate `RestartAllContainersOnContainerExits` by default. The RestartAllContainersOnContainerExits feature is promoted to beta. ([#136681](https://github.com/kubernetes/kubernetes/pull/136681), [@yuanwang04](https://github.com/yuanwang04)) [SIG Node and Testing]
- Enables Prometheus native histogram support in apiserver when feature gate is enabled.
