Good grief, some of the posts in this thread are patently ridiculous. I gave the release date as 'this Summer' in order to be purposely vague, while giving a rough idea of when to expect it. If I had meant 'before the official end of Summer as defined by ISO 77901-B', I would have given an actual date.
XenForo 1.1 is in a late stage of development and will be available soon. Not today, not tomorrow, not this week... soon. And that is as specific as I am prepared to be right now, there are too many factors at play for me to be any more precise.
