Right then ..... It's finished and is being tested. The FAQ entries are being ommited deliberately. The upgrade script is written and well tested, and everything is peachy
USC 2.0 requires a minimum of vBulletin 3.7.0 RC1
The documentation and change log needs writing, along with the essential upgrade path (do it wrong and you lose your existing contents - so be warned!) and then it can be released. All being well it will be released over the weekend at some point, otherwise it will be Monday. The changelog is very extensive and so it will take a lot of writing.
The only thing not included is an exception for photopost which is simply because there are so many different versions of photopost and they may all have different script names and it would be impossible to even guess what they are.
