The raw data file at http://ziggr.com/heisig/ appears to be mostly correct. But there's at least one difference compared to my fourth edition PDF. The keyword for 枚 is the form shown on the index (sheet of) instead of the form in the book (a sheet of). The keywords that changed in the fifth edition are based on the list posted in this thread, which might be missing some changes.
This thread mentions a list of keywords in the sixth edition, but it's partially based on a script I hacked together and hasn't been proof-read.
