- 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.

has entered beta and is available by default. You can now [configure startup, liveness, and readiness probes](https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#configure-probes) for your gRPC app
natively within Kubernetes, without exposing an HTTP endpoint or
using an extra executable.

  
  users who have configured this feature gate as `csiMigrationRBD` has to reconfigure the same to `CSIMigrationRBD` from this release. ([#107554](https://github.com/kubernetes/kubernetes/pull/107554), [@humblec](https://github.com/humblec)) [SIG Storage]

since the default timeout (if not specified) is `1s` which may be too small for some exec probes. Ensure that pods relying on this behavior are updated to correctly handle probe timeouts. See [configure probe](https://docs.k8s.io/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#configure-probes) section of the documentation for more details.
