* [beta] Deployments uses a hashing collision avoidance mechanism that ensures new rollouts will not block on hashing collisions anymore. ([kubernetes/features#287](https://github.com/kubernetes/enhancements/issues/287))

#### PodDisruptionBudget

- Added a mechanism for configurable container restarts: _container-level restart rules_. This was an alpha feature behind the `ContainerRestartRules` feature gate. ([#132642](https://github.com/kubernetes/kubernetes/pull/132642), [@yuanwang04](https://github.com/yuanwang04))...

- Deprecate `--record` flag in `kubectl`. The `--record` flag is being replaced with the [mechanism](https://github.com/kubernetes/enhancements/tree/master/keps/sig-cli/859-kubectl-headers) which annotates HTTP requests with kubectl command details. ([#102873](https://github.com/kubernetes/kubernetes/pull/102873), [@soltysh](https://github.com/soltysh))...

- Promoted CRI communication of the cgroup driver mechanism to beta. The `KubeletCgroupDriverFromCRI` feature gate is now in beta and enabled by default. This allows the kubelet to query the container runtime using CRI to determine the mechanism for cgroup management. If the container runtime doesn't support this, the kubelet falls back to using the configuration file (you can also use the deprecated...

The individual variables in the kube-env metadata entry were never meant to be a stable interface and this release note only applies if you are depending on them.
