Thank you for this wonderful leak, and so soon after its release. Testing it now, will edit with an update!
Edit: Files uploaded, have run into NO issues while uploading and installing. Unlike previous versions I've installed, this has no issues posting new topics. Leaked rated as working, and +1 to you my friend; thanks again!
Another Edit: There are a few failed transfers, but they all have to do with a vender part of the forum that likely won't get used (if your forum is so active that you're selling stuff, I imagine you'll just pay for Xenforo)
