The essence of the language has not changed. But C99 came out with a few nice things. There is also C11 which brought in a few new things as well. It would have been nice to bring the book up to C99.

"Modern C" is a good book on some of the new features.

After reading up on C99 I take back what I said. I definitely thought some of those features were older than they are.
