- The `kubectl patch` command no longer exits with exit code 1 when a redundant patch results in a no-op ([#66725](https://github.com/kubernetes/kubernetes/pull/66725), [@juanvallejo](https://github.com/juanvallejo))

- `kubectl diff` now returns 1 only on diff finding changes, and >1 on kubectl errors. The "exit status code 1" message has also been muted. ([#87437](https://github.com/kubernetes/kubernetes/pull/87437), [@apelisse](https://github.com/apelisse)) [SIG CLI and Testing]

## Dependencies

    - **Known issues**

        - Shared PID namespace does not work properly.
          ([#207](https://github.com/kubernetes/community/pull/207#issuecomment-281870043))

        - Docker reports incorrect exit codes for containers.
          ([#41516](https://github.com/kubernetes/kubernetes/issues/41516))

- Docker 1.11.2

    - **Known issues**

        - Kernel crash with Aufs storage driver on Debian Jessie

  - Migrate `pkg/kubelet/(dockershim, network)` to structured logging
  Exit code changed from 255 to 1 ([#98939](https://github.com/kubernetes/kubernetes/pull/98939), [@yangjunmyfm192085](https://github.com/yangjunmyfm192085)) [SIG Network and Node]
  - Migrate `pkg/kubelet/certificate` to structured logging

- Give terminal phase correctly to all pods that will not be restarted. 

  In particular, assign Failed phase to pods which are deleted while pending. Also, assign a terminal 
  phase (Succeeded or Failed, depending on the exit statuses of the pod containers) to pods which
  are deleted while running.
  
  This fixes the issue for jobs using pod failure policy (with JobPodFailurePolicy and PodDisruptionConditions
