IEOS Backend Services:    

1. In order to enhance the liveness performance, dependency between FaceMatch and Liveness has been removed. FaceMatch runs asynchronously from now on. Liveness continues, regardless from FaceMatch. 
2. Fixed liveness performance issues.  
3. Improved aligning the order of liveness steps between WJCS and Investigation Studio.
4. When the value of the number of actions configuration for liveness in Admin Portal equal to 3, then the ratio of the possibility of the requesting  “smile“ action as a first step could increase. For more accurate result, this value can be set to 5. 
5. Provided improved support for liveness on multitenancy environment.
