New Fix in This Release  

Fixes an issue where Delivery Controller telemetry events may stop being reported to the Citrix License Server (LAS). Although this issue does not impact CVAD functionality or user access, the affected site may no longer provide the telemetry data required for the LAS licensing compliance validation. Citrix recommends applying this fix to ensure continued telemetry reporting and maintain LAS compliance. [CVADHELP-33949]
