* It changed the file format
* For some people it was slower that the original version particularly on low end computers
One person was particularly outraged and reverted the whole change.However, the current version does use a similar approach to that which was proposed: https://github.com/ggerganov/llama.cpp/commit/f963b63afa0e05...
Also, there were insights into how to minimize which models needed adjustment. The ideas and code were worked on by at least 2 people, and I'm an outsider on that project, but I didn't see anything untoward like "stealing credit". The magic change wasn't a perfect move, but is the kind of thing I do locally when I don't know the project/binary format well yet, so not exactly the megalomaniacal move it was painted as. Better that only the version number changed, but she's independent and doing good work, so you'd kind of hope she has a self-promotion streak! Changing the magic would be on the very very low end of letting that side go a bit too far, assuming that was the impetus.
