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))

- Fix kubelet from panic after getting the wrong signal ([#98200](https://github.com/kubernetes/kubernetes/pull/98200), [@wzshiming](https://github.com/wzshiming)) [SIG Node]

### Signing Release Artifacts

Release artifacts are [signed](https://github.com/kubernetes/enhancements/issues/3031) using [cosign](https://github.com/sigstore/cosign)
signatures
and there is experimental support for [verifying image signatures](https://kubernetes.io/docs/tasks/administer-cluster/verify-signed-images/).

- Kubeadm: during execution of the "check expiration" command, treat the etcd CA as external if there is a missing etcd CA key file (etcd/ca.key) and perform the proper validation on certificates signed by the etcd CA. Additionally, make sure that the CA for all entries in the output table is included - for both certificates on disk and in kubeconfig files. ([#106925](https://github.com/kubernetes/kubernetes/pull/106925), [@neolit123](https://gi...

  - **apiserver_flowcontrol_priority_level_seat_count_watermarks**: histograms of high and low watermarks of number of seats occupied by executing requests (both regular and final-delay phases included), broken down by priority_level.

- Fixed detection of non-root image user ID.([#78261](https://github.com/kubernetes/kubernetes/pull/78261), [@tallclair](https://github.com/tallclair))
- Signal handling is now initialized within hyperkube commands that require it, such as apiserver and kubelet. ([#76659](https://github.com/kubernetes/kubernetes/pull/76659), [@S-Chan](https://github.com/S-Chan))

* remove time waiting after create storage account (save 25s) ([#56679](https://github.com/kubernetes/kubernetes/pull/56679), [@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))
