Previously I had wondered what it could mean that chapter 7 of the 50th Anniversary History story had not yet been published.  It showed "coming soon".  The US page still shows "coming soon" but other locations have it published.

Reading chapter 7, I don't see anything that couldn't have been published after Montage M released firmware 2.0.  There doesn't seem to be any spoilers for Montage or the YC lines which are the two focuses of the article.

Basically runs through features and philosophy of YC, Montage M, and the ESP software.
