I've let my OCD get the better of me for what I hope is the last time. I did one final (yeah, sure) review of the EBook and made some more editorial changes to improve the flow of the argument. As was true for all previous updates, I didn't change the substance at all.
When I made the previous update, I learned for the first time that updating the book will erase your bookmarks and underlining. I probably should have known this before, but I didn't. Be aware of that if you update this time. But as I say, I expect this will be the last one.
