(The jury all brightened up again.)

  `Please your Majesty,' said the Knave, `I didn't write it, and
they can't prove I did:  there's no name signed at the end.'

  `If you didn't sign it,' said the King, `that only makes the
matter worse.  You MUST have meant some mischief, or else you'd
have signed your name like an honest man.'

  There was a general clapping of hands at this:  it was the

- `kubeadm alpha certs renew` and `kubeadm upgrade` now supports renewal of certificates embedded in KubeConfig files managed by kubeadm; this does not apply to certificates signed by external CAs.  ([#77180](https://github.com/kubernetes/kubernetes/pull/77180), [@fabriziopandini](https://github.com/fabriziopandini))

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

### 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: 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]

  - The requested name did not match the set of authorized names (`x509.HostnameError`)
  - The error surfaced after attempting a connection contained one of the substrings: "certificate is not trusted" or "certificate signed by unknown authority". ([#120736](https://github.com/kubernetes/kubernetes/pull/120736), [@MadhavJivrajani](https://github.com/MadhavJivrajani))

- Addressed an issue where a JWT authenticator set up via `--authentication-config` would encounter failures in verifying tokens not signed with RS256. ([#123282](https://github.com/kubernetes/kubernetes/pull/123282), [@enj](https://github.com/enj))

  // TODO: Test blocking to re-enter monitor after being signaled.
  // TODO: Test interrupts with both interruptible and uninterruptible monitor.
  // TODO: Test multiple waiters: If guard is still satisfied, signal next waiter.
  // TODO: Test multiple waiters: If guard is no longer satisfied, do not signal next waiter.
