Well sadly not many members use c++ (due to the intimidation factor but mostly the massive amount of c# in the co pserver world).
That being said what is it that's out of date? Obviously packets, memm offsets and encryptions changed but that's about it really...
5095+ blowfish has been released in c++, packet structures are on korv's wiki (<3 so much for that lol). The only thing not really public atm is memory offsets and stuff... the basics are still what is important though. With some searching and hard work i'm sure you can figure out some of the new stuff. Sadly i can't be of much use though cause i've stuck with c# so far and don't plan on switching while avoidable.
Best of luck,

Ps: try shooting null a question. He's very helpful and knows alot about coding and c++. There are other great ppl to ask on here but sadly many of them are a bit too interested in their own projects to help (understandable of course)
