### SIG-OpenStack

SIG-OpenStack development was primarily focused on fixing bugs and improving feature parity with OpenStack resources. New features were primarily limited to the external provider in an effort to drive adoption of the OpenStack external provider over the in-tree provider.

In-tree bug fixes and improvements included:

### Documentation

- Enhanced clarity in error messaging when waiting for volume creation ([#118262](https://github.com/kubernetes/kubernetes/pull/118262), [@torredil](https://github.com/torredil)) [SIG Apps and Storage]

### Failing Test

* Update to fluentd-gcp:1.28.3, rebased on ubuntu-slim:0.8 ([#43928](https://github.com/kubernetes/kubernetes/pull/43928), [@ixdy](https://github.com/ixdy))
* Fix polarity of NodePort logic to avoid leaked ports ([#43259](https://github.com/kubernetes/kubernetes/pull/43259), [@thockin](https://github.com/thockin))

- The feature gate was mentioned as `csiMigrationRBD` where it should have been `CSIMigrationRBD` to be in parity with other migration plugins. This release correct the same and keep it as `CSIMigrationRBD`.

    * and CPU usage of the Kube controller manager.
* add  `kubectl replace --raw` and `kubectl delete --raw` to have parity with create and get ([#79724](https://github.com/kubernetes/kubernetes/pull/79724), [@deads2k](https://github.com/deads2k))

## Changelog since v1.25.0-rc.0

## Changes by Kind

### Documentation

- Clarify that the node-port range (kube-apiserver config) must not overlap the nodes' ephemeral range. ([#111697](https://github.com/kubernetes/kubernetes/pull/111697), [@thockin](https://github.com/thockin)) [SIG Network]

- The feature gate was mentioned as `csiMigrationRBD` where it should have been `CSIMigrationRBD` to be in parity with other migration plugins. This release correct the same and keep it as `CSIMigrationRBD`.
  

- **UI**
  - [stable] Kubernetes Dashboard UI - a great looking Kubernetes Dashboard UI with 90% CLI parity for at-a-glance management. [docs](https://github.com/kubernetes/dashboard)

- Modified the error message of `unmanagedFatal` to enhance clarity while preserving grammatical consistency with `unmanagedWarning`. This improvement ensures a more understandable prompt for users. ([#120159](https://github.com/kubernetes/kubernetes/pull/120159), [@Ithrael](https://github.com/Ithrael))

In Kubernetes v1.15, SIG Storage continued work to [enable migration of in-tree volume plugins](https://github.com/kubernetes/enhancements/issues/625) to the Container Storage Interface (CSI). SIG Storage worked on bringing CSI to feature parity with in-tree functionality, including functionality like resizing, inline volumes, and more. SIG Storage introduces new alpha functionality in CSI that doesn't exist in the Kubernetes Storage subsystem yet, like volume cloning.
