 - Fixes a bug defining a default value for a replicas field in a custom resource definition that has the scale subresource enabled ([#90020](https://github.com/kubernetes/kubernetes/pull/90020), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle and Instrumentation]

- From now on, the HPA controller will return an error for the container resource metrics when the feature gate "HPAContainerMetrics" is disabled. As a result, HPA with a container resource metric performs no scale-down and performs only scale-up based on other metrics.

* [fluentd-gcp addon] Bump fluentd-gcp-scaler to v0.5.2 to pick up security fixes. ([#76762](https://github.com/kubernetes/kubernetes/pull/76762), [@serathius](https://github.com/serathius))

- If we set SelectPolicy MinPolicySelect on scaleUp behavior or scaleDown behavior,Horizontal Pod Autoscaler doesn't automatically scale the number of pods correctly ([#95647](https://github.com/kubernetes/kubernetes/pull/95647), [@JoshuaAndrew](https://github.com/JoshuaAndrew)) [SIG Apps and Autoscaling]

  - The deprecated cloud providers `ovirt`, `cloudstack` and `photon` have been removed ([#72178](https://github.com/kubernetes/kubernetes/pull/72178), [@dims](https://github.com/dims))
  - The `Cinder` and `ScaleIO` volume providers have been deprecated and will be removed in a future release. ([#80099](https://github.com/kubernetes/kubernetes/pull/80099), [@dims](https://github.com/dims))

- When downscaling ReplicaSets, ready and creation timestamps are compared in a logarithmic scale. ([#99212](https://github.com/kubernetes/kubernetes/pull/99212), [@damemi](https://github.com/damemi)) [SIG Apps and Testing]
- When the kubelet is watching a ConfigMap or Secret purely in the context of setting environment variables

- Fixed a `v1.28.0` regression where `kube-controller-manager` can crash when `StatefulSet` with `Parallel` policy and PVC labels are scaled up. ([#121142](https://github.com/kubernetes/kubernetes/pull/121142), [@aleksandra-malinowska](https://github.com/aleksandra-malinowska))
