Current version: New features in Kubernetes 1.12

Released in late September 2018, Kubernetes 1.12 brings to general availability the Kubelet TLS Bootstrap.

Also new in Kubernetes 1.12 is support for Microsoft Azure’s virtual machine scale sets (VMSS), a way to set up a group of VMs that automatically ramp up or down on schedule or to meet demand. Kubernetes’s cluster-autoscaling feature now works with VMSS.
