I wonder if that's cached somewhere, the old documentation was removed and the new one replaced it entirely. Could you try again, and refresh your page? Thank you for reporting this.
I just tried it on a different computer and you're right, it went to the new version. Thanks.
Btw, what's the best place to ask questions? Here, the subreddit, PM?
Subreddit if it would benefit others, otherwise you can email me at the support email address!
