• Bug Fixes
  • Fix a bug where the removal of an outbound rule from standard load balancer
    in the AKS node resource group could cause the failure of subsequent
    cluster operations.
  • Fixed the issue impacting GPU enabled clusters being unable to install the
    required NVidia drivers.
  • Fixed an issue where customers could encounter a CSE (custom script
    extension) error 99 during operations.
  • Fixed an issue with the Azure Portal cluster metrics multiplying the metric
    count based on the viewed window of time. Moving forward the default for
    these metrics will be correctly set to average() as opposed to sum().
    • For customers with metrics already enabled and in-use in portal, the sum()
      type will continue to be supported.
• Component Updates
  • AKS-Engine has been updated to v0.40.1
• Preview Features
  • Fixed an issue where nodes provisioned by cluster autoscaler would be
    de-provisioned when resetting or updating AAD credentials.
