For detailed release notes on the three alpha features from SIG AWS, please refer to the following Changelogs:

- Kubeadm: add support for certificate chain validation. When using kubeadm in external CA mode, this allows an intermediate CA to be used to sign the certificates. The intermediate CA certificate must be appended to each signed certificate for this to work correctly. ([#97266](https://github.com/kubernetes/kubernetes/pull/97266), [@robbiemcmichael](https://github.com/robbiemcmichael)) [SIG Cluster Lifecycle]

* Allow kubernetes components to react to SIGTERM signal and shutdown gracefully. ([#57756](https://github.com/kubernetes/kubernetes/pull/57756), [@mborsz](https://github.com/mborsz))

* Allow kubernetes components to react to SIGTERM signal and shutdown gracefully. ([#57756](https://github.com/kubernetes/kubernetes/pull/57756), [@mborsz](https://github.com/mborsz))

- Adds "volume.beta.kubernetes.io/migrated-to" annotation to PV's and PVC's when they are migrated to signal external provisioners to pick up those objects for Provisioning and Deleting. ([#87098](https://github.com/kubernetes/kubernetes/pull/87098), [@davidz627](https://github.com/davidz627)) [SIG  Storage]

  - The requested name does not match the set of authorized names (x509.HostnameError)
  - The error surfaced after attempting a connection contains one of the substrings: "certificate is not trusted" or "certificate signed by unknown authority" ([#120767](https://github.com/kubernetes/kubernetes/pull/120767), [@MadhavJivrajani](https://github.com/MadhavJivrajani)) [SIG Architecture and Cloud Provider]

* fix azure disk not available issue when device name changed ([#57549](https://github.com/kubernetes/kubernetes/pull/57549), [@andyzhangx](https://github.com/andyzhangx))
* Allow kubernetes components to react to SIGTERM signal and shutdown gracefully. ([#57756](https://github.com/kubernetes/kubernetes/pull/57756), [@mborsz](https://github.com/mborsz))

  - The requested name does not match the set of authorized names (x509.HostnameError)
  - The error surfaced after attempting a connection contains one of the substrings: "certificate is not trusted" or "certificate signed by unknown authority" ([#120768](https://github.com/kubernetes/kubernetes/pull/120768), [@MadhavJivrajani](https://github.com/MadhavJivrajani)) [SIG Architecture and Cloud Provider]

  E0303 17:25:03.436809 63839 helpers.go:680] eviction manager: failed to construct signal: "allocatableMemory.available" error: system container "pods" not found in metrics ([#88970](https://github.com/kubernetes/kubernetes/pull/88970), [@mysunshine92](https://github.com/mysunshine92)) [SIG Node]

### Failing Test

- E2e tests: fixed bug in the e2e image `agnhost:2.38` which hangs instead of exiting if a `SIGTERM` signal is received and the `shutdown-delay` option is `0`. ([#110214](https://github.com/kubernetes/kubernetes/pull/110214), [@aojea](https://github.com/aojea))
