• The API has been updated to v1beta1, with one new Custom Resource Definition added: ClusterMaster. Refer the revised Custom Resources and Examples documentation for details on all the changes. This is a major update and is not backward-compatible. You will have to completely remove any older versions, and any resources managed by the operator, before upgrading to this release.

0.1.0 Alpha

• This release depends upon changes made concurrently in the Splunk
  Enterprise container images. You must use the latest splunk/splunk:edge
  nightly image with it, or alternatively any release version 8.0.3 or later.

• The API has been updated to v1alpha2, and involves the replacement of
  the SplunkEnterprise custom resource with 5 new custom resources:
  Spark, LicenseMaster, Standalone, SearchHeadCluster and IndexerCluster.
  Please read the revised Custom Resources and
  Examples documentation for details on all the changes. This
  is a major update and is not backwards-compatible. You will have to
  completely remove any older versions, and any resources managed by the
  operator, before upgrading to this release.

• Scaling, upgrades and other updates are now more actively managed for the
  SearchHeadCluster and IndexerCluster resources. This helps protect against
  data loss and maximizes availability while changes are being made. You can
  now also use the "kubectl scale" command, and Horizontal Pod Autoscalers
  with all resources (except LicenseMaster, which always uses a single Pod).

• A new serviceTemplate spec parameter has been added for all Splunk Enterprise
  custom resources. This may be used to define a template the operator uses for
  the creation of (non headless) services.

• Splunk Enterprise clusters may now be created without having to provide a
  license file via the licenseURL parameter. When no license is provided,
  a default trial license will now be used.

• Annotations and labels from the managed custom resources are now appended
  to any corresponding Pod and Service objects that the operator creates.

• A unique pass4SymmKey secret will now be randomly generated, to resolve
  cluster master warnings about using the default value.

• Integrated with CircleCI and Coverall for CICD and code coverage, and
  added a bunch of unit tests to bring coverage up to over 90%.
