It's more than 10 years ago.
And it's always been a bit ambiguous. Personally, I'd be inclined to say that at this point, everyone's human, but I'm not going to go so far as to attempt to make that a GM fiat.
I think somewhat more important is not assuming someone's race—just because they're in Sirion doesn't mean they're an elf, so unless you happen to know that a particular character is roleplayed as such by their player, don't claim that they are one.
