Write yourself a side project using as many features as you can.
Or write a cheatsheet (multiple pages) for C++11 onward, taking care to detail example cases of each new item or construct or keyword.
You'll know no end of idiosyncrasies in no time.
Remember, that was ~6 years ago and that's a long time. If we're still writing C++2003 and haven't fully looked into C++11 and beyond or learned swathes of it (like many many many of my colleagues and C++ devs I meet, some of whom call it C++0x), that means they're working to a spec 14 years old (C++2003). 14 years old is a teenager.
