- `PodSpec.Container.Resources` became mutable for CPU and memory resource types.
  - `PodSpec.Container.ResizePolicy` (new object) gives users control over how their containers are resized.
  - `PodStatus.Resize` status describes the state of a requested Pod resize.
  - `PodStatus.ResourcesAllocated` describes node resources allocated to Pod.
  - `PodStatus.Resources` describes node resources applied to running containers by CRI.

New alpha features include:
* Online volume resizing will increase the filesystem size of a resized volume without requiring a Pod restart.
* AWS EBS and GCE PD volumes support increased limits on the maximum number of attached volumes per node.
* Subpath volume directories can be created using DownwardAPI environment variables.

* 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

[Documentation](https://docs.k8s.io) & [Examples](https://releases.k8s.io/release-1.7/examples)

* 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))

* Resolves an issue that prevented block volumes from being resized. ([#81429](https://github.com/kubernetes/kubernetes/pull/81429), [@huffmanca](https://github.com/huffmanca))

### Feature

- Add NeedResize function to kubernetes/mount-utils, user can call this function to determine if fs need to be resized ([#101253](https://github.com/kubernetes/kubernetes/pull/101253), [@AndyXiangLi](https://github.com/AndyXiangLi)) [SIG Storage]
- Base image updates to mitigate kube-proxy and etcd container image CVEs

- The pod `status.resize` field is now deprecated and will no longer be set. The status of a pod resize will be exposed under two new conditions: `PodResizeInProgress` and `PodResizePending` instead. ([#130733](https://github.com/kubernetes/kubernetes/pull/130733), [@natasha41575](https://github.com/natasha41575))...

- Pod resize now only allows CPU and memory resources; other resource types are forbidden. ([#135084](https://github.com/kubernetes/kubernetes/pull/135084), [@tallclair](https://github.com/tallclair)) [SIG Apps, Node and Testing]

renamed to NodeToStatusReader. ([#126022](https://github.com/kubernetes/kubernetes/pull/126022), [@macsko](https://github.com/macsko)) [SIG Node, Scheduling, and Testing]

- A new /resize subresource was added to request pod resource resizing. Update your k8s client code to utilize the /resize subresource for Pod resizing operations.
