- Fixed a 1.25.12 regression where kube-controller-manager can crash when StatefulSet with Parallel policy and PVC labels is scaled up. ([#121187](https://github.com/kubernetes/kubernetes/pull/121187), [@aleksandra-malinowska](https://github.com/aleksandra-malinowska)) [SIG Apps]

### Autoscaling

- Horizontal Pod Autoscaling can now scale targets up even when one or more metrics are invalid/unavailable, as long as one metric indicates a scale up should occur. ([#78503](https://github.com/kubernetes/kubernetes/pull/78503), [@gjtempleton](https://github.com/gjtempleton))


### AWS

## Notable Changes to Existing Behavior

### Deployments

- ReplicaSets of paused Deployments are now scaled while the Deployment is paused. This is retroactive to existing Deployments.
- When scaling a Deployment during a rollout, the ReplicaSets of all Deployments are now scaled proportionally based on the number of replicas they each have instead of only scaling the newest ReplicaSet.

* StatefulSet: Fix to fully preserve restart and termination order when StatefulSet is rapidly scaled up and down. ([#45113](https://github.com/kubernetes/kubernetes/pull/45113), [@kow3ns](https://github.com/kow3ns))

which is an integer.
        * ScaleRef of type SubresourceReference in HorizontalPodAutoscalerSpec which
referred to scale subresource of the resource being scaled was replaced by
ScaleTargetRef which points just to the resource being scaled.
        * In extensions/v1beta1 if CPUUtilization in HorizontalPodAutoscalerSpec was not
specified it was set to 80 by default while in autoscaling/v1 HPA object

* [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))

* Calico has been updated to v2.5, RBAC added, and is now automatically scaled when GCE clusters are resized. ([#51237](https://github.com/kubernetes/kubernetes/pull/51237), [@gunjan5](https://github.com/gunjan5))



# v1.7.5

* AWS kube-up: move to Docker 1.11.2 ([#27676](https://github.com/kubernetes/kubernetes/pull/27676), [@justinsb](https://github.com/justinsb))
* Fixed an issue that Deployment may be scaled down further than allowed by maxUnavailable when minReadySeconds is set. ([#27728](https://github.com/kubernetes/kubernetes/pull/27728), [@janetkuo](https://github.com/janetkuo))



# v1.3.0-beta.2

- 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))

- Fixed a 1.26.7 regression where kube-controller-manager can crash when StatefulSet with Parallel policy and PVC labels is scaled up. ([#121186](https://github.com/kubernetes/kubernetes/pull/121186), [@aleksandra-malinowska](https://github.com/aleksandra-malinowska)) [SIG Apps]
