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  - The "JoinConfiguration.discovery.timeout" field has been replaced by "JoinConfiguration.timeouts.discovery".

  *  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))

- 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))

- Kubeadm: Fixed a bug where the default args for etcd were not correct when a local etcd image was used and the etcd version was less than 3.6.0. ([#133023](https://github.com/kubernetes/kubernetes/pull/133023), [@carlory](https://github.com/carlory))

- 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))

  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]

- Alowed useful inclusion of `-args $prog_args` in KUBE_TEST_ARGS, when doing `make test-integration`. ([#107516](https://github.com/kubernetes/kubernetes/pull/107516), [@MikeSpreitzer](https://github.com/MikeSpreitzer))
