BI 3 stopped receiving updates entirely when V4 was released. You could still click the button but it would just tell you that BI 4 was now available.What happened when V4 was released? Were V3 updates still available or did they cease? Could be V5 is almost here.
I imagine it would take some pretty exceptional circumstances for Ken to build another V4 update after V5 is out. Like if a Windows update or something made it unusable for a significant number of people, or a serious security vulnerability was discovered.
