  * <strong>Simplified application deployment and management. </strong>
     * Dynamic Configuration (ConfigMap API in the core API group) enables application
configuration to be stored as a Kubernetes API object and pulled dynamically on
container startup, as an alternative to baking in command-line flags when a
container is built.

- Updated the feature MultiCIDRServiceAllocator to beta (disabled by default). Users need to enable the feature gate and the networking v1beta1 group to be able to use this new feature, that allows to dynamically reconfigure Service CIDR ranges.

- Fixed a bug that prevented deletion of dynamically provisioned volumes in Quobyte backends. ([#68925](https://github.com/kubernetes/kubernetes/pull/68925), [@casusbelli](https://github.com/casusbelli))
