+
+Properties Prs3d_Drawer::HLRAngle() and Prs3d_Drawer::HLRDeviationCoefficient() have been removed from classes *Prs3d_Drawer*, *AIS_Shape* and *AIS_InteractiveContext*.
+Prs3d_Drawer::DeviationAngle() should be now used instead of Prs3d_Drawer::HLRAngle() and Prs3d_Drawer::DeviationCoefficient() instead of Prs3d_Drawer::HLRDeviationCoefficient().
+The default value of Prs3d_Drawer::DeviationAngle() property has been changed from 12 to 20 degrees to match removed Prs3d_Drawer::HLRAngle(), previously used as input for triangulation algorithm.
