+* Improvement in handling Interval Protection Level while using **tab_multi_manager()**:
+
+> The IP levels are now set automatically into the apriori files for actual Primary Suppressed Cells 
+and only them. This ensures IP to be applied only for the actual primary secret and limits the 
+propagation of suppressions due to IP manipulation. In some very particular cases, this can lead to 
+significantly reduce  the suppressions.
