This is not the major release of the year so there isn't too much to talk about. As for fixing the build issue I wouldn't hold your breath. I've already seen someone mention that the build for an lvlibp failed with error 1502. Cannot save a bad VI without its block diagram. But turning on debugging allowed it to build properly.
