* Fixed potential deadlock when deleting CustomResourceDefinition for custom resources with finalizers. ([#60542](https://github.com/kubernetes/kubernetes/pull/60542), [@liggitt](https://github.com/liggitt))

* A buffered audit backend can be used with other audit backends. ([#60076](https://github.com/kubernetes/kubernetes/pull/60076), [@crassirostris](https://github.com/crassirostris))

If the capacity is zero or absent, the channel is unbuffered and communication
succeeds only when both a sender and receiver are ready. Otherwise, the channel
is buffered and communication succeeds without blocking if the buffer
is not full (sends) or not empty (receives).
A <code>nil</code> channel is never ready for communication.
