The first change is a bugfix with the cxrefdep (the default) method; there was a problem where if a struct field had the same name as a function in another source file, a false node and edge would appear in the resulting graph. Name collision resolution is also much better now. The second major change is the introduction of the cncc method which is based on the ncc compiler (available via freshmeat). This is a C compiler designed for code navigation and its major advantage over existing collection methods is the ability to traverse function pointers.
