Changelog since v1.16.0-alpha.2

Action Required

• ACTION REQUIRED: (#80676, @fabriziopandini)
  • kubeadm now deletes the bootstrap-kubelet.conf file after TLS bootstrap
  • User relying on bootstrap-kubelet.conf should switch to kubelet.conf that contains node credentials

Other notable changes

• kubeadm: fix "certificate-authority" files not being pre-loaded when using file discovery (#80966, @neolit123)
• Errors from pod volume set up are now propagated as pod events. (#80369, @jsafrane)
• kubeadm: enable secure serving for the kube-scheduler (#80951, @neolit123)
• Kubernetes client users may disable automatic compression when invoking Kubernetes APIs by setting the DisableCompression field on their rest.Config. This is recommended when clients communicate primarily over high bandwidth / low latency networks where response compression does not improve end to end latency. (#80919, @smarterclayton)
• kubectl get did not correctly count the number of binaryData keys when listing config maps. (#80827, @smarterclayton)
• Implement "post-filter" extension point for scheduling framework (#78097, @draveness)
• Reduces GCE PD Node Attach Limits by 1 since the node boot disk is considered an attachable disk (#80923, @davidz627)
• This PR fixes an error when using external etcd but storing etcd certificates in the same folder and with the same name used by kubeadm for local etcd certificates; for an older version of kubeadm, the workaround is to avoid file name used by kubeadm for local etcd. (#80867, @fabriziopandini)
• When specifying --(kube|system)-reserved-cgroup, with --cgroup-driver=systemd, it is now possible to use the fully qualified cgroupfs name (i.e. /test-cgroup.slice). (#78793, @mattjmcnaughton)
• kubeadm: treat non-fatal errors as warnings when doing reset (#80862, @drpaneas)
• kube-addon-manager has been updated to v9.0.2 to fix a bug in leader election (https://github.com/kubernetes/kubernetes/pull/80575) (#80861, @mborsz)
• Determine system model to get credentials for windows nodes. (#80764, @liyanhui1228)
• TBD (#80730, @jennybuckley)
• The AdmissionReview API sent to and received from admission webhooks has been promoted to admission.k8s.io/v1. Webhooks can specify a preference for receiving v1 AdmissionReview objects with admissionReviewVersions: ["v1","v1beta1"], and must respond with an API object in the same apiVersion they are sent. When webhooks use admission.k8s.io/v1, the following additional validation is performed on their responses: (#80231, @liggitt)
  * response.patch and response.patchType are not permitted from validating admission webhooks
  * apiVersion: "admission.k8s.io/v1" is required
  * kind: "AdmissionReview" is required
  * response.uid: "<value of request.uid>" is required
  * response.patchType: "JSONPatch" is required (if response.patch is set)
• "kubeadm join" fails if file-based discovery is too long, with a default timeout of 5 minutes. (#80804, @olivierlemasle)
• enhance Azure cloud provider code to support both AAD and ADFS authentication. (#80841, @rjaini)
• Attempt to set the kubelet's hostname & internal IP if --cloud-provider=external and no node addresses exists (#75229, @andrewsykim)
• kubeadm: avoid double deletion of the upgrade prepull DaemonSet (#80798, @xlgao-zju)
• Fixes problems with connecting to services on localhost on some systems; in particular, DNS queries to systemd-resolved on Ubuntu. (#80591, @danwinship)
• Implement normalize plugin extension point for the scheduler framework. (#80383, @liu-cong)
• Fixed the bash completion error with override flags. (#80802, @dtaniwaki)
• Fix CVE-2019-11247: API server allows access to custom resources via wrong scope (#80750, @sttts)
• Failed iscsi logout is now re-tried periodically. (#78941, @jsafrane)
• Fix public IP not found issues for VMSS nodes (#80703, @feiskyer)
• In order to enable dual-stack support within kubeadm and kubernetes components, as part of the init config file, the user should set feature-gate IPv6DualStack=true in the ClusterConfiguration. Additionally, for each worker node, the user should set the feature-gate for kubelet using either nodeRegistration.kubeletExtraArgs or KUBELET_EXTRA_ARGS. (#80531, @Arvinderpal)
• Fix error in kubeadm join --discovery-file when using discovery files with embedded credentials (#80675, @fabriziopandini)
