== Custom Metrics Autoscaler Operator 2.13.1 release notes
|

|

This release of the Custom Metrics Autoscaler Operator 2.13.1-421 provides a new feature and a bug fix for running the Operator in an {product-title} cluster. The following advisory is available for the link:https://access.redhat.com/errata/RHBA-2024:4837[RHBA-2024:4837].

==== Support for custom certificates with the Custom Metrics Autoscaler Operator
|
||||
|
||||
The Custom Metrics Autoscaler Operator can now use custom service CA certificates to connect securely to TLS-enabled metrics sources, such as an external Kafka cluster or an external Prometheus service. By default, the Operator uses automatically-generated service certificates to connect to on-cluster services only. There is a new field in the `KedaController` object that allows you to load custom server CA certificates for connecting to external services by using config maps.

* Previously, the `custom-metrics-autoscaler` and `custom-metrics-autoscaler-adapter` images were missing time zone information. As a consequence, scaled objects with `cron` triggers failed to work because the controllers were unable to find time zone information. With this fix, the image builds are updated to include time zone information. As a result, scaled objects containing `cron` triggers now function properly. Scaled objects containing `cron` triggers are currently not supported for the custom metrics autoscaler. (link:https://issues.redhat.com/browse/OCPBUGS-34018[*OCPBUGS-34018*])

The Custom Metrics Autoscaler Operator can now use the Cron trigger to scale pods based on an hourly schedule. When your specified time frame starts, the Custom Metrics Autoscaler Operator scales pods to your desired amount. When the time frame ends, the Operator scales back down to the previous level.

|
||||
|
||||
* Previously, if you made changes to audit configuration parameters in the `KedaController` custom resource, the `keda-metrics-server-audit-policy` config map would not get updated. As a consequence, you could not change the audit configuration parameters after the initial deployment of the Custom Metrics Autoscaler. With this fix, changes to the audit configuration now render properly in the config map, allowing you to change the audit configuration any time after installation.
