- Kubeadm: during 'upgrade apply', if the kube-proxy ConfigMap is missing, assume that kube-proxy should not be upgraded. Same applies to a missing kube-dns/coredns ConfigMap for the DNS server addon. Note that this is a temporary workaround until 'upgrade apply' supports phases. Once phases are supported the kube-proxy/dns upgrade should be skipped manually.

- Fixes a regression introduced in 1.29 where conntrack entries for UDP connections
  to deleted pods did not get cleaned up correctly, which could (among other things)
  cause DNS problems when DNS pods were restarted. ([#127806](https://github.com/kubernetes/kubernetes/pull/127806), [@danwinship](https://github.com/danwinship)) [SIG Network]

- `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

- Allow to monitor client-go DNS resolver latencies via `rest_client_dns_resolution_duration_seconds` Prometheus metric. ([#115357](https://github.com/kubernetes/kubernetes/pull/115357), [@mfojtik](https://github.com/mfojtik))
