- `client-go`, using log level 9, traces the following events of a HTTP request:
      - DNS lookup
      - TCP dialing
      - TLS handshake
      - Time to get a connection from the pool
      - Time to process a request ([#105156](https://github.com/kubernetes/kubernetes/pull/105156), [@aojea](https://github.com/aojea))

### Documentation

- Kubeadm: Removed support for mounting /etc/pki as an additional Linux system CA location
  in kube-apisever and kube-controller-manager pods. Instead, it shifted to supporting the
  mounting of /etc/pki/ca-trust and /etc/pki/tls/certs. The locations /etc/ca-certificate,
  /usr/share/ca-certificates, /usr/local/share/ca-certificates, and /etc/ssl/certs continued

- Added a warning that TLS 1.3 ciphers are not configurable. ([#115399](https://github.com/kubernetes/kubernetes/pull/115399), [@3u13r](https://github.com/3u13r)) [SIG API Machinery and Node]
