That's news to me. Could you possibly mean the one that came in Volume 10 which rearranged the chapters and numbers such that we received a new chapter 70 which gave proper conclusion to the arc?

A translated version of that chapter is around the interent somewhere. Better yet check the Chapter 70 page on the wiki.
