Easily upgrade your clusters to Kubernetes v1.15.1
We are excited to announce the availability of Kubernetes v1.15.1 for your clusters that are running in IBM Cloud Kubernetes Service. With the Kubernetes Service, you can easily upgrade your clusters without the need for deep Kubernetes knowledge. When you deploy new clusters, the default Kubernetes version remains 1.13; you can also choose to immediately deploy version 1.15.

In addition to all the great Kubernetes features provided in this release, IBM Cloud Kubernetes Service version 1.15.1 also includes the following:
- Calico updated to version 3.8.1
- Kubernetes addon resizer updated to version 1.8.5
- Kubernetes DNS auto-scaler updated to version 1.6.0
- Support for the Kubernetes NodeLocal DNS Cache beta feature
Kubernetes support and updates
IBM Cloud Kubernetes Service now supports the latest three versions of Kubernetes: 1.13, 1.14, and 1.15. Clusters that are running Kubernetes versions 1.11 and earlier are unsupported.
Clusters running 1.12 are now deprecated with end-of-support tentatively scheduled for October 31. It is important to note clusters that run deprecated or unsupported Kubernetes versions may not receive fixes for security vulnerabilities until they are updated to a supported version.
