We are happy to release KEDA v2.13 🎉

Here are some highlights:

• Support for GCP Secret Manager & config map in trigger authentication
• Newly improved AWS authentication
• Support for emitting CloudEvents from KEDA allowing end-users to extend KEDA (Experimental)
• Support for Amazon managed service for Prometheus for Prometheus scaler
• SAS token authentication for Azure Storage scalers
• Workload identity authentication for Azure Pipelines
• Additional metrics and performance improvements

Here are the breaking changes of this release:

• General: Clean up previously deprecated code in Azure Data Explorer Scaler about clientSecret for 2.13 release (#5051)

Here are the new deprecation(s) as of this release:

• Remove support for Azure AD Pod Identity-based authentication (#5035)
