  * This will ensure certain commands in 1.5 versions of kubectl continue function when run against a 1.6 server. (e.g. `kubectl edit deployment`)
* Taint
  * The `taint` command will not function in a skewed 1.5 / 1.6 environment - client and server versions must match (See Action required section above)

* locking fix in vSphere cleanup function ([#68388](https://github.com/kubernetes/kubernetes/pull/68388), [@wgliang](https://github.com/wgliang))
    * The vSphere cloud provider has a cleanup function with a loop,
    * inside of which a write lock was intended to prevent races against

	    * The new metrics are:

	    * cloudprovider_gce_api_request_duration_seconds{request, region, zone}

	    * cloudprovider_gce_api_request_errors{request, region, zone}

	    * request is the specific function that is used.

	    * region is the target region (Will be "<n/a>" if not applicable)

	    * zone is the target zone (Will be "<n/a>" if not applicable)

* Fix panic in kubectl rollout commands ([#69151](https://github.com/kubernetes/kubernetes/pull/69151), [@soltysh](https://github.com/soltysh))
* Fix scheduler crashes when Prioritize Map function returns error. ([#69135](https://github.com/kubernetes/kubernetes/pull/69135), [@DylanBLE](https://github.com/DylanBLE))

- `client-go` event library allows customizing spam filtering function. 
  It is now possible to override `SpamKeyFunc`, which is used by event filtering to detect spam in the events. ([#103918](https://github.com/kubernetes/kubernetes/pull/103918), [@olagacek](https://github.com/olagacek))
