The previous code relied too much on assertions, even for things that are just regular things that may happen while the application is running (like running out of memory). - Many assertions have been turned into permanent checks - Some functions now return "success" or "failure". - NE_Init3D() and NE_InitDual3D() (and others) have been reworked to handle failures gracefully.
