We’re pleased to announce the delivery of Kubernetes 1.13, our fourth and final release of 2018!
Kubernetes 1.13 has been one of the shortest releases to date at 10 weeks. This release continues to focus on stability and extensibility of Kubernetes with three major features graduating to general availability this cycle in the areas of Storage and Cluster Lifecycle.
