While the core language has stayed the same the tooling and development environment has changed quite a lot. Proper modern compiler flags (-Wall etc) for example would be a huge help to new learners and for best practices, but k&r isn't mentioning these. I still think it's a good book but if you throw it at someone new to this they're going to be wondering why what they are writing isn't behaving as expected.
