Kubernetes 1.15 consists of **25 enhancements**: 2 moving to stable, 13 in beta, and 10 in alpha. The main themes of this release are:

#### Continuous Improvement

### OpenStack

SIG-OpenStack updated the OpenStack provider to use newer APIs, consolidated community code into one repository, engaged with the Cloud Provider Working Group to have a consistent plan for moving provider code into individual repositories, improved testing of provider code, and strengthened ties with the OpenStack developer community.

### API-machinery

- [`KT-59718`](https://youtrack.jetbrains.com/issue/KT-59718) K/JS: Concatenating a String with a Char can lead to boxing of the Char
- [`KT-59717`](https://youtrack.jetbrains.com/issue/KT-59717) K/JS: a redundant boxing of a returned Char from an inline function

- New repository created for [Windows Operational Readiness](https://github.com/kubernetes-sigs/windows-operational-readiness)

### Moved container registry service from k8s.gcr.io to registry.k8s.io

     1. Be authorized to make the create or update API request
     2. Be allowed to bind the referenced role, either by already having all of the permissions contained in the referenced role, or by having the "bind" permission on the referenced role.

* Add `metrics-port` to kube-proxy cmd flags. ([#72682](https://github.com/kubernetes/kubernetes/pull/72682), [@whypro](https://github.com/whypro))
* Reduce memory utilization of admission webhook metrics by removing resource related labels. ([#69895](https://github.com/kubernetes/kubernetes/pull/69895), [@jpbetz](https://github.com/jpbetz))

- Promote CSIMigrationAWS to Beta (off by default since it requires installation of the AWS EBS CSI Driver) ([#85237](https://github.com/kubernetes/kubernetes/pull/85237), [@leakingtapan](https://github.com/leakingtapan))
- Moving Windows RunAsUserName feature to beta ([#84882](https://github.com/kubernetes/kubernetes/pull/84882), [@marosset](https://github.com/marosset))

### CLI Improvements

- Fixes an issue calculating total CPU usage reported for Windows nodes ([#122999](https://github.com/kubernetes/kubernetes/pull/122999), [@marosset](https://github.com/marosset)) [SIG Node and Windows]
- Prevent watch cache starvation by moving its watch to separate RPC and add a SeparateCacheWatchRPC feature flag to disable this behavior ([#123693](https://github.com/kubernetes/kubernetes/pull/123693), [@mengqiy](https://github.com/mengqiy)) [SIG API Machinery]

* Allow having empty paths in *path operations* used with `include_router` and a `prefix`.
    * This allows having a router for `/cats` and all its *path operations*, while having one of them for `/cats`.
    * Now it doesn't have to be only `/cats/` (with a trailing slash).
