* Demoted controlplane passthrough flags apiserver-extra-args, controller-manager-extra-args, scheduler-extra-args to alpha flags ([#59882](https://github.com/kubernetes/kubernetes/pull/59882), [@kris-nova](https://github.com/kris-nova))

- 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))

- 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))

- The `--leader-elect*` CLI args are now honored in scheduler. ([#105915](https://github.com/kubernetes/kubernetes/pull/105915), [@Huang-Wei](https://github.com/Huang-Wei))
- The `--leader-elect*` CLI args are now honored in the scheduler. ([#105712](https://github.com/kubernetes/kubernetes/pull/105712), [@Huang-Wei](https://github.com/Huang-Wei))

- 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.
  

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

- 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))

  
  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  - The "JoinConfiguration.discovery.timeout" field has been replaced by "JoinConfiguration.timeouts.discovery".

  When running test/e2e via the Ginkgo CLI, the v2 CLI must be used and `-timeout=24h` (or some other, suitable value) must be passed because the default timeout was reduced from 24h to 1h. When running it via `go test`, the corresponding `-args` parameter is `-ginkgo.timeout=24h`. To build the CLI in the Kubernetes repo, use `make all WHAT=github.com/onsi/ginkgo/v2/ginkgo`.

- Kubectl: Previously users cannot provide arguments to a external diff tool via KUBECTL_EXTERNAL_DIFF env. This release now allow users to specify args to KUBECTL_EXTERNAL_DIFF env. ([#95292](https://github.com/kubernetes/kubernetes/pull/95292), [@dougsland](https://github.com/dougsland)) [SIG CLI]
