- Fix the bug where image garbage collection is disabled by mistake. ([#66051](https://github.com/kubernetes/kubernetes/pull/66051), [@jiaxuanzhou](https://github.com/jiaxuanzhou))

- client-go discovery clients constructed using `NewDiscoveryClientForConfig` or `NewDiscoveryClientForConfigOrDie` default to rate limits that cause normal discovery request patterns to take several seconds. This is fixed in https://issue.k8s.io/86168 and will be resolved in v1.17.1. As a workaround, the `Burst` value can be adjusted higher in the rest.Config passed into `NewDiscoveryClientForConfig` or `NewDiscoveryClientForConfigOrDie`....

- Fix that prevents repeated fetching of PVC/PV objects by kubelet when processing of pod volumes fails. While this prevents hammering API server in these error scenarios, it means that some errors in processing volume(s) for a pod could now take up to 2-3 minutes before retry. ([#88141](https://github.com/kubernetes/kubernetes/pull/88141), [@tedyu](https://github.com/tedyu)) [SIG Node and Storage]

- Fixed incorrect calculation for ResourceQuota with PriorityClass as its scope. ([#117677](https://github.com/kubernetes/kubernetes/pull/117677), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG API Machinery]

*   Add `--etcd-compaction-interval` to apiserver for controlling request of compaction to etcd3 from apiserver. ([#51765](https://github.com/kubernetes/kubernetes/pull/51765),[ @mitake](https://github.com/mitake))
*   The httpstream/spdy calls now support CIDR notation for NO_PROXY ([#54413](https://github.com/kubernetes/kubernetes/pull/54413),[ @kad](https://github.com/kad))

* Webhooks now do not skip cluster-scoped resources. Before upgrading your Kubernetes clusters, double check whether you have configured webhooks for cluster-scoped objects (e.g., nodes, persistentVolume), as these webhooks will start to take effect. Delete/modify the configs if that's not desirable. ([#58185](https://github.com/kubernetes/kubernetes/pull/58185), [@caesarxuchao](https://github.com/caesarxuchao))

- Fix the regression with the slow pods termination. Before this fix pods may take an additional time to terminate - up to one minute. Reversing the change that ensured that CNI resources cleaned up when the pod is removed on API server. ([#97980](https://github.com/kubernetes/kubernetes/pull/97980), [@SergeyKanzhelev](https://g...

  
  Also, compute the backoff delay more accurately for deleted pods. ([#119466](https://github.com/kubernetes/kubernetes/pull/119466), [@mimowo](https://github.com/mimowo)) [SIG Apps]

* Update to use go1.10.3 ([#65726](https://github.com/kubernetes/kubernetes/pull/65726), [@ixdy](https://github.com/ixdy))
* Fix the bug where image garbage collection is disabled by mistake. ([#66051](https://github.com/kubernetes/kubernetes/pull/66051), [@jiaxuanzhou](https://github.com/jiaxuanzhou))
