We are happy to release KEDA 2.7.0 🎉

Here are some highlights:

  • Introduction of pausing autoscaling through annotations for ScaledObject.
  • Introduce ARM-based container image
  • Introduction of AWS DynamoDB, Azure Data Explorer, GCP Stackdriver & GCP Storage scalers
  • Introduction of Azure Key Vault as trigger authentication provider
  • KEDA is secure-by-default and runs as non-root
  • Support for non-public Microsoft Azure clouds
  • 19 new contributors
  • Deprecation of metadata.type is deprecated in favor of the global metricType for CPU, Memory, Datadog scalers (GitHub Discussion)
