- The Pod Certificates feature moved to beta. The `PodCertificateRequest` feature gate is set disabled by default. To use the feature, users must enable the certificates API groups in `v1beta1` and enable the `PodCertificateRequest` feature gate. The `UserAnnotations` field was added to the `PodCertificateProjection` API and the corresponding...

- Kubeadm: a new command `kubeadm alpha certs check-expiration` was created in order to help users in managing expiration for local PKI certificates ([#77863](https://github.com/kubernetes/kubernetes/pull/77863),...

* [beta] Kubelet certificate rotation through the certificates API has been promoted from alpha to beta. RBAC cluster roles for the certificates controller have been added for common uses of the certificates API, such as the kubelet's.

 *  Fix: Don't silently ignore calls to `EventSource.cancel()` made from
    `EventSourceListener.onOpen()`.
 *  Fix: Enforce the max intermediates constraint when using pinned certificates with Conscrypt.
    This impacts Conscrypt when the server's presented certificates form both a trusted-but-unpinned
    chain and an untrusted-but-pinned chain.
 *  Upgrade: [Kotlin 1.6.10][kotlin_1_6_10].
