* addon-resizer flapping behavior was removed. ([#46850](https://github.com/kubernetes/kubernetes/pull/46850), [@x13n](https://github.com/x13n))
* Change default `httpGet` probe `User-Agent` to `kube-probe/<version major.minor>` if none specified, overriding the default Go `User-Agent`. ([#47729](https://github.com/kubernetes/kubernetes/pull/47729), [@paultyng](https://github.com/paultyng))

- If someone had the `ProbeTerminationGracePeriod` alpha feature enabled in 1.21, they should update/delete any workloads/pods with probe `terminationGracePeriods` < 1 before upgrading ([#103245](https://github.com/kubernetes/kubernetes/pull/103245), [@wzshiming](https://github.com/wzshiming))

* Flush conntrack state for removed/changed UDP Services ([#22573](https://github.com/kubernetes/kubernetes/pull/22573), [@freehan](https://github.com/freehan))
* Allow setting the Host header in a httpGet probe ([#24292](https://github.com/kubernetes/kubernetes/pull/24292), [@errm](https://github.com/errm))

* Added liveness probe to Heapster service. ([#31878](https://github.com/kubernetes/kubernetes/pull/31878), [@mksalawa](https://github.com/mksalawa))

- Kubeadm: Switched to using the new etcd endpoints introduced in 3.5.11 - /livez (for liveness probe) and /readyz (for readyness and startup probe). With this change it is no longer possible to deploy a custom etcd version older than 3.5.11 with kubeadm 1.31. If so, please upgrade etcd to a supported version. ([#124465](https://github.com/kubernetes/kubernetes/pull/124465),...

- Implemented logging and event recording for probe results with an `Unknown` status in the kubelet's prober module. This helped improve the diagnosis and monitoring of cases where container probes returned an `Unknown` result, enhancing the observability and reliability of health checks. ([#125901...

### Deprecated/changed metrics

- kubelet probe metrics are now of the counter type rather than the gauge type, and the `prober_probe_result` has been replaced by `prober_probe_total`. ([#76074](https://github.com/kubernetes/kubernetes/pull/76074), [@danielqsj](https://github.com/danielqsj))
