You can have new tools without breaking the old ones. We didn't
have to change BCPL to get B, or B to get C, or C to get D or C++.
 
This really is a very simple point, but perhaps a simple analogy
will help to clarify it. You don't throw out your 3/4" just
because you've bought a 19mm. There is room for both in the
toolbox, and why write 3/4" on your new spanner? It /isn't/ a
3/4" spanner even though it's very like it, so why pretend otherwise?

That's why C99 is called C99, to distinguish it from C90 (and similarly
for later versions). None of those revisions is large enough to justify
giving the revised language an entirely new name.
