-=== JSON diff for Elastic prebuilt rule updates
+=== Per-field diff for Elastic prebuilt rule updates
 
-When Elastic updates a prebuilt detection rule, you can examine the latest version before you {security-guide}/prebuilt-rules-management.html#update-prebuilt-rules[update the rule]. The rule details flyout in **Rule Updates** displays a side-by-side JSON comparison of the rule's **Base version** (what you currently have installed) and the **Update version** that you can choose to install.
+When examining an {security-guide}/prebuilt-rules-management.html#update-prebuilt-rules[updated Elastic prebuilt detection rule], you can now view rule changes field by field as well as in a full JSON view.

+=== Refined header design for alert details flyout 
 
-You can now {security-guide}/alerts-ui-manage.html#assign-users-to-alerts[assign users to alerts] that you want them to investigate, and manage alert assignees throughout an alert's lifecycle. Assigned alerts are filterable, and you can find assignees by adding the `kibana.alert.workflow_assignee_ids` field to the Alerts table or by opening an alert's details.
+The header design for the {security-guide}/view-alert-details.html[alert details flyout] has been refined to improve readability and structure. Basic alert details now appear clearer and more organized.

For example, you can assign **Extreme impact** to business-critical entities, or **Low impact** to entities that pose minimal risk to your security posture.
+
+The risk scoring engine includes asset criticality as an input when calculating entity risk scores.
+
+With asset criticality, you can strengthen your threat detection capabilities by focusing your alert triage, threat-hunting, and investigation activities on high-impact entities.

-== New Osquery query timeout setting
+=== Benchmark rules can be turned off
 
-When running an Osquery query, you can now set a timeout period, in seconds, after which the query will stop running. Overwriting the default timeout allows you to support queries that require more time to complete. The default and minimum supported value is `60`. The maximum supported value is `900`.
+You can now turn individual {security-guide}/cspm-benchmark-rules.html[benchmark rules] on or off. This allows you to customize your Cloud Security Posture Management (CSPM) and Kubernetes Security Posture Management (KSPM) integrations to reduce noise from benchmark rules that don't apply to your environment.
