You can now use existing endpoints to define multiple recurrence patterns for correlation rules with the introduction of a new scheduleConfig property.

Recurrence patterns include several recurrence types (Daily, Weekly, Monthly, Custom). This offers granular control over when correlation rules are active, including specific times, days of the week, or days of the month.

You can now use improved versions of the following Threat Center endpoints:

These endpoints offer new options for case closure and context and now support validated closedReason values — ensuring consistency and accuracy as well as a new supportingReason free text field — allowing you to provide additional context when closing cases. These improvements help streamline case management and improve data quality across your workflows.

As such, the previous versions of these endpoints, Update case details (DEPRECATED) and Create a new case (DEPRECATED) will be supported for 6 months until April 15, 2026, after which they will be deprecated.
