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)

Learn how to deploy KEDA by reading our documentation.
