 # Datadog changelog
 
+## 3.87.0
+
+* Launch `otel-agent` with the `--core-config` switch pointing to the main agent configuration. Note that this affects the OTel Agent beta images, early beta image releases with version tag `<7.59.0-v.1.2.0` will experience issues and should remain on older helm chart versions for their deployments. For regular users not deploying the `otel-agent` beta images, this should be a NOOP.   
+
 ## 3.86.0
 
 * Add `delete` permission for `datadog-webhook` Admission Registration RBACs.

 [Datadog](https://www.datadoghq.com/) is a hosted infrastructure monitoring platform. This chart adds the Datadog Agent to all nodes in your cluster via a DaemonSet. It also optionally depends on the [kube-state-metrics chart](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-state-metrics). For more information about monitoring Kubernetes with Datadog, please refer to the [Datadog documentation website](https://docs.datadoghq.com/agent/basic_agent_usage/kubernetes/).
