## Changelog since v1.15.0-alpha.1

### Other notable changes

* Kubemark scripts have been fixed for IKS clusters. ([#76909](https://github.com/kubernetes/kubernetes/pull/76909), [@Huang-Wei](https://github.com/Huang-Wei))

- Kubemark: added two flags, `--kube-api-qps` which indicates the maximum QPS to the apiserver, and `--kube-api-burst` which indicates maximum burst for throttle to the apiserver. ([#124147](https://github.com/kubernetes/kubernetes/pull/124147), [@devincd]...

* Deviceplugin jiayingz ([#51209](https://github.com/kubernetes/kubernetes/pull/51209), [@jiayingz](https://github.com/jiayingz))
* Make logdump support kubemark and support gke with 'use_custom_instance_list' ([#51834](https://github.com/kubernetes/kubernetes/pull/51834), [@shyamjvs](https://github.com/shyamjvs))

- Kubectl: deprecated command line flags (like several of the klog flags) now have a `DEPRECATED: <explanation>` comment. ([#106172](https://github.com/kubernetes/kubernetes/pull/106172), [@pohly](https://github.com/pohly)) [SIG CLI]
- Kubemark is now built as a portable, static binary. ([#106150](https://github.com/kubernetes/kubernetes/pull/106150), [@pohly](https://github.com/pohly)) [SIG Scalability and Testing]

components that do not expect non-empty, non-flag arguments will now print an error message and exit if an argument is specified: cloud-controller-manager, kube-apiserver, kube-controller-manager, kube-proxy, kubeadm {alpha|config|token|version}, kubemark. Flags should be prefixed with a single dash "-" (0x45) for short form or double dash "--" for long form. Before this change, malformed flags (for example, starting with a non-ascii dash character such as 0x8211: "–") would have been silently treated...

- Adds two kubemark flags, `--max-pods` and `--extended-resources`. ([#100267](https://github.com/kubernetes/kubernetes/pull/100267), [@Jeffwan](https://github.com/Jeffwan))
