- Fixed a bug in the TopologyManager. Previously, the TopologyManager would only guarantee alignment if container creation was serialized in some way. Alignment is now guaranteed under all scenarios of container creation. ([#87759](https://github.com/kubernetes/kubernetes/pull/87759), [@klueska](https://github.com/klueska)) [SIG Node]

- Moved Recover from volume expansion failure to GA. ([#132662](https://github.com/kubernetes/kubernetes/pull/132662), [@gnufied](https://github.com/gnufied)) [SIG Apps, Auth, Node, Storage and Testing]

- Added metrics to expose the main known reasons for resource alignment errors ([#129950](https://github.com/kubernetes/kubernetes/pull/129950), [@ffromani](https://github.com/ffromani)) [SIG Node and Testing]

  Kubernetes will keep allowing leading zeros on IPv4 address to not break the compatibility.
  IMPORTANT: Kubernetes interprets leading zeros on IPv4 addresses as decimal, users must not rely on parser alignment to not being impacted by the associated security advisory:

* Fixed potential infinite loop that can occur when NFS PVs are recycled. ([#62572](https://github.com/kubernetes/kubernetes/pull/62572), [@joelsmith](https://github.com/joelsmith))
* Fixed column alignment when kubectl get is used with custom columns from OpenAPI schema ([#56629](https://github.com/kubernetes/kubernetes/pull/56629), [@luksa](https://github.com/luksa))

* Enforcement of fsGroup; enable ScaleIO multiple-instance volume mapping; default PVC capacity; alignment of PVC, PV, and volume names for dynamic provisioning ([#48999](https://github.com/kubernetes/kubernetes/pull/48999), [@vladimirvivien](https://github.com/vladimirvivien))



# v1.7.4

* Enforcement of fsGroup; enable ScaleIO multiple-instance volume mapping; default PVC capacity; alignment of PVC, PV, and volume names for dynamic provisioning ([#48999](https://github.com/kubernetes/kubernetes/pull/48999), [@vladimirvivien](https://github.com/vladimirvivien))

### Additional Notable Feature Updates

- [Topology Manager](https://github.com/kubernetes/enhancements/issues/693), a new Kubelet component, aims to co-ordinate resource assignment decisions to provide optimized resource allocations.
- [IPv4/IPv6 dual-stack](https://kubernetes.io/docs/concepts/services-networking/dual-stack) enables the allocation of both IPv4 and IPv6 addresses to Pods and Services.

[soft-reserve a range for static IP address assignments](https://kubernetes.io/docs/concepts/services-networking/service/#service-ip-static-sub-range)
to Services.
With the manual enablement of this feature, the cluster will prefer automatic assignment from
the pool of Service IP addresses thereby reducing the risk of collision.

A Service `ClusterIP` can be assigned:
