- Fixed an issue where kubelet does not set case-insensitive headers for http probes. (#117182, @dddddai) ([#117324](https://github.com/kubernetes/kubernetes/pull/117324), [@dddddai](https://github.com/dddddai)) [SIG API Machinery, Apps and Node]

    * action required: Cloud providers other than GCE might want to update their deployments or sample yaml files to reuse the role created via add-on.

### Other notable changes

* Kubernetes json deserializer is now case-sensitive to restore compatibility with pre-1.8 servers. ([#65157](https://github.com/kubernetes/kubernetes/pull/65157), [@caesarxuchao](https://github.com/caesarxuchao))

## Changelog since v1.9.8

### Action Required

* ACTION REQUIRED: Kubernetes JSON deserializer is now case-sensitive to restore compatibility with pre-1.8 servers. If your config files contains fields with wrong case, the config files will be now invalid. ([#65298](https://github.com/kubernetes/kubernetes/pull/65298), [@nikhita](https://github.com/nikhita))

* Adding metrics support to local volume ([#49598](https://github.com/kubernetes/kubernetes/pull/49598), [@sbezverk](https://github.com/sbezverk))
* Bug fix: Parsing of `--requestheader-group-headers` in requests should be case-insensitive. ([#49219](https://github.com/kubernetes/kubernetes/pull/49219), [@jmillikin-stripe](https://github.com/jmillikin-stripe))

- AzureFile and CephFS use the new Mount library that prevents logging of sensitive mount options. ([#88684](https://github.com/kubernetes/kubernetes/pull/88684), [@saad-ali](https://github.com/saad-ali)) [SIG Storage]

- Hashing of KeyID in Logs
  

resource definitions during direct API server communication, the keys are case-sensitive. A bug introduced in Kubernetes 1.8 caused the API server to accept a request with incorrect case and coerce it to correct case, but this behaviour has been fixed in 1.11 and the API server will once again be enforcing the correct case. It’s worth noting that during this time, the `kubectl` tool continued to enforce case-sensitive keys, so users that strictly manage resources with `kubectl` will be unaffected...

* fix azure disk naming matching issue due to case sensitive comparison ([#81720](https://github.com/kubernetes/kubernetes/pull/81720), [@andyzhangx](https://github.com/andyzhangx))

- Fixed an issue where kubelet does not set case-insensitive headers for http probes. (#117182, @dddddai) ([#117333](https://github.com/kubernetes/kubernetes/pull/117333), [@dddddai](https://github.com/dddddai)) [SIG API Machinery, Apps and Node]

### Feature

- Fix conflicted cache when the requests are canceled by other Azure operations. ([#81282](https://github.com/kubernetes/kubernetes/pull/81282), [@feiskyer](https://github.com/feiskyer))
