9.2.0
^^^^^


New Features
************

* Added label heapster_enabled to control heapster installation in
  the cluster.

* Installs the metrics-server service that is replacing kubernetes
  deprecated heapster as a cluster wide metrics reporting service used
  by schedulling, HPA and others. This service is installed and
  configured using helm and so tiller_enabled flag must be True. The
  label metrics_server_chart_tag can be used to specify the stable
  /metrics-server chart tag to be used. The label
  metrics_server_enabled is used to enable disable the installation of
  the metrics server (default: true).

* Added custom.metrics.k8s.io API installer by means of stable
  /prometheus-adapter helm chart. The label prometheus_adapter_enabled
  (default: true) controls configuration. You can also use
  prometheus_adapter_chart_tag to select helm chart version, and
  prometheus_adapter_configmap if you would like to setup your own
  metrics (specifying this other than default overwrites default
  configurations). This feature requires the usage of label
  monitoring_enabled=true.


Upgrade Notes
*************

* nginx-ingress-controller QoS changed from Guaranteed to Burstable.
  Priority class 'system-cluster-critical' or higher for nginx-
  ingress-controller.


Bug Fixes
*********

* A regression issue about downloading images has been fixed. Now
  both Fedora Atomic driver and Fedora CoreOS driver can support using
  proxy in template to create cluster.

* nginx-ingress-controller requests.memory increased to 256MiB. This
  is a result of tests that showed the pod getting oom killed by the
  node on a relatively generic use case.

* k8s-keystone-auth now uses the upstream k8scloudprovider docker
  repo instead of the openstackmagnum repo.

* Fixes the next url in the list nodegroups API response.

* Bump up prometheus operator chart version to 8.2.2 so that it is
  compatible with k8s 1.16.x.

* Bump up traefik to 1.7.19 for compatibility with Kubernetes
  1.16.x.
