Platform9 5.0 is Live

Platform9 Managed Kubernetes Version 5.0 Release Notes

The 5.0 release of Platform9 includes major enhancements over the 4.x releases with significant changes in the API layer as well as the Web App. Our focus for this release was to decouple the Platform9 SaaS Management Plane and our Host Side components so that users are able to run multiple Kubernetes versions simultaneously, and upgrade their clusters at their own pace.

Release Highlights

When using Platform9 managed Kubernetes 5.0 to deploy new Kubernetes clusters you are able to select your desired version of Kubernetes. Once a cluster is running, and when an upgrade is available, you are able to choose either a Patch (1.17.9 to 1.17.11) or a Minor (1.17.x to 1.18.x) Upgrade.
