This new release focuses on improving the tooling and developer experience. This release introduces an experimental demo of the next-generation v3 API, a new Go etcd client, and active cluster connectivity checking.
etcd is an open source, distributed, consistent key-value store for shared configuration, service discovery and scheduler coordination. etcd is a core component of the CoreOS software stack and is used to facilitate safe automatic updates in CoreOS Linux. It is the primary scheduling and service discovery data store in Kubernetes and is leveraged by hundreds of other tools and projects.
