Warning

Before installing this version of the Custom Metrics Autoscaler Operator, remove any previously installed Technology Preview versions or the community-supported version of Kubernetes-based Event Driven Autoscaler (KEDA).

Bug fixes
  • Before this update, the default scaling strategy for scaled jobs was missing. With this fix, the default strategy has been added back to the scaledjobs custom resource. As a result, you can select the default strategy with scaled jobs. (OCPBUGS-121352)

Note

This issue was initially addressed in the Custom Metrics Autoscaler 2.19.0-3 release through OCPBUGS-98657. However, the fix did not fully address the problem. Updating to the Custom Metrics Autoscaler 2.19.0-4 release will fix this issue.
