If the key type is an interface type, these
comparison operators must be defined for the dynamic key values;
failure will cause a <a href="#Run_time_panics">run-time panic</a>.

The number of map elements is called its length.

*   The Kubelet's feature gates are now specified as a map when provided via a JSON or YAML KubeletConfiguration, rather than as a string of key-value pairs, making them less awkward for users....

* Use Cluster Autoscaler 0.5.1, which fixes an issue in Cluster Autoscaler 0.5 where the cluster may be scaled up unnecessarily. Also the status of Cluster Autoscaler is now exposed in kube-system/cluster-autoscaler-status config map. ([#43745](https://github.com/kubernetes/kubernetes/pull/43745), [@mwielgus](https://github.com/mwielgus))



# v1.6.0

- Fixed a Windows kube-proxy (winkernel) issue where stale `RemoteEndpoints`
  remained when a Deployment was referenced by multiple Services due to premature
  clearing of the `terminatedEndpoints` map. ([#135146](https://github.com/kubernetes/kubernetes/pull/135146), [@princepereira](https://github.com/princepereira)) [SIG Network and Windows]

- Resolve a "concurrent map read and map write" crashing error in the kubelet ([#95111](https://github.com/kubernetes/kubernetes/pull/95111), [@choury](https://github.com/choury)) [SIG Node]

- Fixed a bug where adding an ephemeral container to a pod which references a new secret or config map doesn't give the pod access to that new secret or config map. (#114984, @cslink) ([#129670](https://github.com/kubernetes/kubernetes/pull/129670), [@cslink](https://github.com/cslink)) [SIG Auth]

- Fixed bug in CPUManager with race on container map access ([#97427](https://github.com/kubernetes/kubernetes/pull/97427), [@klueska](https://github.com/klueska)) [SIG Node]

* On COS, NPD creates a node condition for frequent occurrences of unregister_netdevice ([#65342](https://github.com/kubernetes/kubernetes/pull/65342), [@dashpole](https://github.com/dashpole))
* Fix concurrent map access panic ([#65328](https://github.com/kubernetes/kubernetes/pull/65328), [@dashpole](https://github.com/dashpole))
    * Don't watch .mount cgroups to reduce number of inotify watches
    * Fix NVML initialization race condition

### Bug or Regression

- EndpointSlice Mirroring controller now cleans up managed EndpointSlices when a Service selector is added (#106136, @robscott) [SIG Apps, Network and Testing]
- Fix concurrent map access causing panics when logging timed-out API calls. (#106124, @marseel) [SIG API Machinery]
- Support more than 100 disk mounts on Windows (#105673, @andyzhangx) [SIG Storage and Windows]
