Christian: perhaps you should highlight in your initial post that the installation method is different; it can be the first bullet on the "what's new" summary portion of your post.
I mention this not only because of Jamey's confusion but of my own as well. Luckily, after experiencing similar errors in the release, I decided to RTFM and solved the problem. So, when you announce the final release of 1.6, make it bold, underlined and super-sized text that the installation procedure has changed.
