 === Insights Operator
 
-* The Insights Operator now collects the `haproxy_exporter_server_threshold` metric. (link:https://issues.redhat.com/browse/OCPBUGS-36687[*OCPBUGS-36687*])
+// Engineering reference CCXDEV-12582
 
-* Previously, the Insights Operator gathered information about all Ingress Controller certificates, including their `NotBefore` and `NotAfter` dates. This data is now compiled into a `JSON` file located at `aggregated/ingress_controllers_certs.json` for easier monitoring of certificate validity across the cluster. (link:https://issues.redhat.com/browse/OCPBUGS-35727[*OCPBUGS-35727*])
+The Insights Operator can now collect more of your {product-title} data and generate recommendations much faster.
+Enhancements have also been made to give you more flexibility in how the data to be collected gets defined for your service.
+
+==== Rapid Recommendations
+
+This release introduces a new feature called Rapid Recommendations, which provides a more dynamic and version-independent mechanism for remotely configuring the rules that determine which data the Insights Operator collects.
+
+Rapid Recommendations builds on the existing conditional data gathering mechanism, whereby the Insights Operator connects to a secure remote endpoint service running on `/console.redhat.com` to retrieve definitions of the data to collect.
+
+The conditional data-gathering definitions, also referred to as rules, get configured through an attribute named `conditionalGathererEndpoint` in the link:https://github.com/openshift/insights-operator/blob/master/config/pod.yaml[`pod.yml`] configuration file.
+
+```bash
+conditionalGathererEndpoint: https://console.redhat.com/api/gathering/v2/%s/gathering_rules
+```
+
+NOTE: Previously, the rules for determining the data that the Insights Operator collects were hard-coded and tied to the corresponding {product-title} version.
+The preconfigured endpoint URL now provides a placeholder (`%s`) for defining a target version of {product-title}.
+
+==== More data collected and recommendations added
+
+The Insights Operator now gathers more data to detect the following scenarios and offer remedial recommendations to help you proactively manage your {product-title} deployments:
+
+// Engineering reference: CCXDEV-12899
+* Detection of pods and namespaces for deployments that use the link:https://access.redhat.com/articles/7065170[deprecated OpenShiftSDN CNI plugin] and a recommendation of the actions to take depending on the data collected.
+// Engineering reference: OSPRH-5904
+* Collects custom resource definitions (CRD) from {rh-openstack}.
+// Engineering reference: CCXDEV-13001
+* Collects the `haproxy_exporter_server_threshold` metric to detect the problem and remediation reported in (link:https://issues.redhat.com/browse/OCPBUGS-36687[*OCPBUGS-36687*]).
+// Engineering reference: CCXDEV-12758
+* Collects data to detect custom Prometheus Alertmanager instances that are not in the "openshift-monitoring" namespace because they could potentially impact the management of corresponding resources.
+// Engineering reference: CCXDEV-12503
+* Detects the upcoming expiry of the default ingress controller expiration certificate and generates a recommendation to renew the certificate before the expiry date.
+// Engineering reference: OCPBUGS-35727
+    ** Before this update, the Insights Operator gathered information about all Ingress Controller certificates, including their `NotBefore` and `NotAfter` dates. This data is now compiled into a `JSON` file located at `aggregated/ingress_controllers_certs.json` for easier monitoring of certificate validity across the cluster.
