Date filed	Issue number	Description
2022-08-31	CIM-1108	Adaptive Response relay errors occur when polling a Splunk Cloud search head cluster that is configured with the Spunk_SA_CIM modular action worker. Workaround: Following two options are available to resolve the errors: Option 1: Configure the search head cluster. This is a quick solution but might cause false positive errors. Configure the heavy forwarders to poll all search heads in the search head cluster, instead of the search head cluster URL. This guarantees the retrieval and dequeing of the alert from the search head that generated the alert. However, the other four search heads still display errors. Option 2: Enhancements to Splunk_SA_CIM: Splunk_SA_CIM/lib/splunk_sa_cim/modaction_queue.py Create a custom version of the Splunk_SA_CIM with the updated modaction_queue.py file and components to generate an alert. The custom app does not impact the Splunk_SA_CIM app or data model acceleration.
2022-06-29	CIM-1099	ES SOAR adaptive response actions not working.
2022-03-16	CIM-1087	The Change.json data model includes incorrect constraint searches.
2022-01-25	CIM-1081	Update "recommended" field for Change.user_name, Change.src_user_name, and Alerts.user_name.
