`Interrupted(error) bool` helper to replace checks for `err == ErrWaitTimeout`, or compare specifically to context errors as needed. A future release will make the `ErrWaitTimeout` error private and callers must use `Interrupted()` instead. If you are returning `ErrWaitTimeout` from your own methods, switch to creating a location specific `cause err` and pass it to the new method `wait.ErrorInterrupted(cause) error` which will ensure `Interrupted()` returns true for your loop.

- The Usage and VolumeCondition are both optional in the response and if CSIVolumeHealth feature gate is enabled kubelet needs to consider returning metrics if either one is set. ([#127021](https://github.com/kubernetes/kubernetes/pull/127021), [@Madhu-1](https://github.com/Madhu-1)) [SIG Storage]

- Added validation to ensure `log-flush-frequency` is a positive value, returning an error instead of causing a panic. ([#133540](https://github.com/kubernetes/kubernetes/pull/133540), [@BenTheElder](https://github.com/BenTheElder)) [SIG Architecture, Instrumentation, Network and Node]

  After a time she heard a little pattering of feet in the
distance, and she hastily dried her eyes to see what was coming.
It was the White Rabbit returning, splendidly dressed, with a
pair of white kid gloves in one hand and a large fan in the
other:  he came trotting along in a great hurry, muttering to
himself as he came, `Oh! the Duchess, the Duchess! Oh! won't she

  **How can I migrate?**
  
  For backward compatibility, nil `QueueingHintFn` is treated as always returning QueueAfterBackoff. 
  So, if you want to just keep the existing behavior, you can register `ClusterEventWithHint` with no `QueueingHintFn` in it. 

- Added alpha support for `WindowsHostNetworking` feature. ([#112961](https://github.com/kubernetes/kubernetes/pull/112961), [@marosset](https://github.com/marosset))

* Protobuf serialization does not distinguish between `[]` and `null`.
API fields previously capable of storing and returning either `[]` and `null` via JSON API requests (for example, the Endpoints `subsets` field)
can now store only `null` when created using the protobuf content-type or stored in etcd using protobuf serialization (the default in 1.6).
