[id="nodes-pods-autoscaling-custom-rn-2172-new-controller_{context}"]
81+
==== The KEDA controller is automatically created during installation
82+
83+
The KEDA controller is now automatically created when you install the Custom Metrics Autoscaler Operator. Previously, you needed to manually create the KEDA controller. You can edit the automatically-created KEDA controller, as needed. For more information, see xref:../../../nodes/cma/nodes-cma-autoscaling-custom-install.adoc#nodes-cma-autoscaling-keda-controller-edit_nodes-cma-autoscaling-custom-install[Editing the Keda Controller CR].

86+
==== Support for the Kubernetes workload trigger
87+
88+
The Cluster Metrics Autoscaler Operator now supports using the Kubernetes workload trigger to scale pods based on the number of pods matching a specific label selector. For more information, see xref:../../../nodes/cma/nodes-cma-autoscaling-custom-trigger#nodes-cma-autoscaling-custom-trigger-workload_nodes-cma-autoscaling-custom-trigger[Understanding the Kubernetes workload trigger].

[id="nodes-pods-autoscaling-custom-rn-2172-new-tokens_{context}"]
91+
==== Support for bound service account tokens
92+
93+
The Cluster Metrics Autoscaler Operator now supports bound service account tokens. Previously, the Operator supported only legacy service account tokens, which are being phased out in favor of bound service account tokens for security reasons. For more information see xref:../../../nodes/cma/nodes-cma-autoscaling-custom-trigger-auth.adoc#nodes-cma-autoscaling-custom-trigger-auth[Understanding custom metrics autoscaler trigger authentications].

[id="nodes-pods-autoscaling-custom-rn-2172-bugs_{context}"]
96+
=== Bug fixes
97+
98+
* Previously, the KEDA controller did not support volume mounts. As a result, you could not use Kerberos with the Kafka scaler. With this fix, the KEDA controller now supports volume mounts. (link:https://issues.redhat.com/browse/OCPBUGS-42559[*OCPBUGS-42559*])
99+
* Previously, the KEDA version in the `keda-operator` deployment object log reported that the Custom Metrics Autoscaler Operator was based on an incorrect KEDA version. With this fix, the correct KEDA version is reported in the log. (link:https://issues.redhat.com/browse/OCPBUGS-58129[*OCPBUGS-58129*])
