New Fix in This Release 

In environments with multiple license entitlements, end users might see a license expiration warning during session launch and administrators might see a warning in Citrix Studio if any entitlement on the License Server is expired or expiring. This issue occurs even when a valid and active entitlement for the current product is present. [CVADHELP-32258]    

Fixes from Replaced Updates 

Race condition during licensing state transitions could lead to incorrect license caching mode period calculations. This prevents session launches (CVADHELP-31920).
