Yes. New CJK compatibility ideographs U+FA70..U+FAD9 have canonical
decompositions into single characters. For example NFC(U+FACF) =
U+2284A (for the first time a BMP character is normalized to something
outside BMP).

These are the only differences in NFC/NFD between Unicode 4.0.1 and 4.1.0.

There are 48 more differences in NFKC/NFKD.
