Incompatibility with Version 5.1
The class IlvMakePolyPointsInteractor and its subclasses:
The method
virtual void react(IlvPoint& p, IlUShort modifier = 0);
now has one extra argument that contains the configuration of the keyboard modifiers when the event that generated the addition of a point was triggered. This extra argument enables the overriden methods to position the point depending on these modifiers.
While it is highly unlikely that this method has been overridden, if this is the case, a compile-time error will occur. In this case, the derived method's signature should simply be extended to include this extra argument.
