The API does include a few breaking changes:
  - The "extraArgs" component construct is now a list of "name"/"value" pairs instead of a string/string map. This has been done to support duplicate args where needed.
  - The "JoinConfiguration.discovery.timeout" field has been replaced by "JoinConfiguration.timeouts.discovery".

- Take the context as the first argument of Schedule. ([#82119](https://github.com/kubernetes/kubernetes/pull/82119), [@wgliang](https://github.com/wgliang))
- Fixed an issue that the correct PluginConfig.Args is not passed to the corresponding PluginFactory in kube-scheduler when multiple PluginConfig items are defined. ([#82483](https://github.com/kubernetes/kubernetes/pull/82483), [@everpeace](https://github.com/everpeace))

- Updates the commands `
   - kubectl kustomize {arg}
   - kubectl apply -k {arg}

- E2e framework: retrying after intermittent `apiserver` failures was fixed in `WaitForPodsResponding` ([#120559](https://github.com/kubernetes/kubernetes/pull/120559), [@pohly](https://github.com/pohly))

- Add a helper function to decode scheduler plugin args. ([#80696](https://github.com/kubernetes/kubernetes/pull/80696), [@hex108](https://github.com/hex108))
- Fix filter plugins are not been called during preemption ([#81876](https://github.com/kubernetes/kubernetes/pull/81876), [@wgliang](https://github.com/wgliang))

- Support more than 100 disk mounts on Windows (#105673, @andyzhangx) [SIG Storage and Windows]
- The --leader-elect* CLI args are now honored correctly in scheduler. (#106130, @Huang-Wei) [SIG Scheduling]
- The kube-proxy sync_proxy_rules_iptables_total metric now gives
  the correct number of rules, rather than being off by one.
  

  *  Use StorageClassName for etcd pvc ([#46323](https://github.com/kubernetes/kubernetes/pull/46323), [@marun](https://github.com/marun))

* Bug fixes:

	* Allow disabling federation controllers through override args ([#44209](https://github.com/kubernetes/kubernetes/pull/44209), [@irfanurrehman](https://github.com/irfanurrehman))

- Kubectl now handles newlines for `command`, `args`, `env`, and `annotations` in `kubectl describe` wrapping. ([#66841](https://github.com/kubernetes/kubernetes/pull/66841), [@smarterclayton](https://github.com/smarterclayton))

  (at the cost of an occasional pod being scheduled non-optimally/violating existing
  pods preferred inter-pod affinities). To enable this scheduler option, set the
  `InterPodAffinity` scheduler plugin arg `ignorePreferredTermsOfExistingPods: true` ([#114393](https://github.com/kubernetes/kubernetes/pull/114393), [@danielvegamyhre](https://github.com/danielvegamyhre))
