- 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]

  
  **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.

  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

* 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).
