Well, it is a MUGEN update out of many by NRF, since the last recent update on 2017-10-07.
If you can then you might want to try to mention what was being updated in this 2017-10-22 version.
NRF has a habit to put his MUGEN update log in his "
天覇活殺.txt" file.
By the way, I like NRF's SS2 MUGEN characters very much, his Jyubei Yagyu is my favorite!
