A minor security issue has been found and fixed in 1.7.1

• Do not print credentials in build output or logs. Only affects certain pipeline steps like withDockerRegistry. sh step is not affected

Other interesting new feature is the support of multiple containers in declarative pipeline #306 JENKINS-48135

15 releases have gone by in 7 months since 1.0 last September

Some interesting new features since 1.0 and a lot of bugfixes and overall stability improvements. For instance now you can use yaml to define the Pod that will be used for your job:

def label = "mypod-${UUID.randomUUID().toString()}"
podTemplate(label: label, yaml: """
apiVersion: v1
kind: Pod
metadata:
  labels:
    some-label: some-label-value
spec:
  containers:
  - name: busybox
    image: busybox
    command:
    - cat
    tty: true
"""
) {
    node (label) {
      container('busybox') {
        sh "hostname"
      }
    }
}

You can use readFile step to load the yaml from a file in your git repo.

• Allow creating Pod templates from yaml. This allows setting all possible fields in Kubernetes API using yaml JENKINS-50282 #275
• Support passing kubeconfig file as credentials using secretFile credentials JENKINS-49817 #294
