- Port mapping now allows the same `containerPort` of different containers to different `hostPort` without naming the mapping explicitly. ([#94494](https://github.com/kubernetes/kubernetes/pull/94494), [@SergeyKanzhelev](https://github.com/SergeyKanzhelev))

The Kubernetes in-tree storage plugin to Container Storage Interface (CSI) migration infrastructure is now beta in Kubernetes v1.17. CSI migration was introduced as alpha in Kubernetes v1.14.

## Known Issues
- volumeDevices mapping ignored when container is privileged

* `nodeSelector.matchFields` (node's `metadata.node`) is now supported in scheduler. ([#62453](https://github.com/kubernetes/kubernetes/pull/62453), [@k82cn](https://github.com/k82cn))
* Added a parametrizable priority function mapping requested/capacity ratio to priority. This function is disabled by default and can be enabled via the scheduler policy config file.

Initially, the bound type parameters are known but the map is empty.
During type unification, if a new type argument <code>A</code> is inferred,
the respective mapping <code>P ➞ A</code> from type parameter to argument
is added to the map.
Conversely, when comparing types, a known type argument
(a type argument for which a map entry already exists)

- Support allocating whole NUMA nodes in the CPUManager when there is not a 1:1 mapping between socket and NUMA node ([#102015](https://github.com/kubernetes/kubernetes/pull/102015), [@klueska](https://github.com/klueska))

* Fixed regression in initial kubectl exec terminal dimensions ([#51127](https://github.com/kubernetes/kubernetes/pull/51127), [@chen-anders](https://github.com/chen-anders))
* 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))

- Fix removing pods from podTopologyHints mapping ([#101892](https://github.com/kubernetes/kubernetes/pull/101892), [@aheng-ch](https://github.com/aheng-ch)) [SIG Node]

#### Other Notable Changes
* Federated Ingress over GCE no longer requires separate firewall rules to be created for each cluster to circumvent flapping firewall health checks. ([#41942](https://github.com/kubernetes/kubernetes/pull/41942), [@csbell](https://github.com/csbell))

- Added `SchedulerPopFromBackoffQ` feature gate that is in beta and enabled by default. Improved scheduling queue behavior by popping pods from the backoffQ when the activeQ is empty. This allows to process potentially schedulable pods ASAP, eliminating a penalty effect of the backoff queue.
