== Bug fixes

* Previously, when deleting a `ClusterPodPlacementConfig` with the `execFormatErrorMonitor` plugin enabled, the MTO could get stuck in a `Deleting` state because some resources were not deleted. With this update, all relevant resources are removed so that the deletion is successful. link:https://redhat.atlassian.net/browse/MULTIARCH-6186[(MULTIARCH-6186)]

* Previously, a race condition between the `eNoExecEvent` daemon and the handler controller caused the `ENoExecEvent` CR to be rolled back before its status could be set, preventing any exec format errors from being recorded. With this update the conflict so events are captured successfully. link:https://redhat.atlassian.net/browse/MULTIARCH-6207[(MULTIARCH-6207)]

* Previously, deleting a `ClusterPodPlacementConfig` object could tear down the webhook and operand resources while `PodPlacementConfigs` still existed, orphaning them without the resources they depend on. The deletion is now properly gated and blocks if any `PodPlacementConfig` objects remain. link:https://redhat.atlassian.net/browse/MULTIARCH-6236[(MULTIARCH-6236)]

[id="multi-arch-tuning-operator-1-3-2-enhancements_{context}"]
== Enhancements

* MTO has been updated to use `go` version 1.26.3.

* When the MTO is unable to connect to an image registry, the resulting error message has been improved to better explain the error. link:https://redhat.atlassian.net/browse/MULTIARCH-5541[(MULTIARCH-5541)]

* The MTO API has been updated to use `runtime.NewSchemeBuilder` instead of the deprecated `scheme.Builder`. link:https://redhat.atlassian.net/browse/MULTIARCH-6272[(MULTIARCH-6272)]
