    **Fixed** an issue preventing the gateway chart from being used with a custom HorizontalPodAutoscaler resource.

upgradeNotes:
  - title: don't set spec.replicas unless user supplies a real number
    content: |
      When using the gateway chart, the user had to either pick between
      explicitly setting `spec.replicas`, or using the chart-supplied
      `HorizontalPodAutoscaler`. Now `spec.replicas` is only set if
