### 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/).

copy `topology.k8s.io/zone`, `topology.k8s.io/region` and `kubernetes.io/hostname` labels from Node objects to Pods when they are scheduled to a node (via the `pods/binding` endpoint) to allow applications that need to be explicitly aware of their assigned node topology to access this information via the downward API, rather than requiring permission to `get node` objects (exposing the entire API surface of the Node object to otherwise unprivileged workloads). ([#127092](https://github.com/kuberne...

- Added the `SizeBasedListCostEstimate` feature gate (enabled by default), which changes how APF seats are assigned to `LIST` requests. With this feature, one seat is assigned per 100KB of data loaded into memory at once during a `LIST` operation.

    when no certificates were pinned. This avoids an SSL failure in insecure

(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
