  description: "Whenever Orthanc receives a new DICOM instance, this event is recorded in the so-called _Changes Log_. This enables remote scripts to react to the arrival of new DICOM resources. A typical application is auto-routing, where an external script waits for a new DICOM instance to arrive into Orthanc, then forward this instance to another modality."
