Sorry, but I haven't looked at it -- other than a cursory glance at some sample pages -- and from an asthetic viewpoint regarding the look of the book, I really don't like it. There were numerous font/style choices that I found jarring or unpleasing, at least to my eye.
As for the content, I don't know the full extent of the changes made, but I do know that the biggest error that I made when authoring HARP was not corrected, and it still exists within the product, and was even carried over into HARP Sci-Fi.
