Except sometimes thread-enabled and thread-incompatible versions co-exist.
That's because you can't link a thread-enabled library with an
application that's built without threads (on many platforms), but you
must link a thread-enabled library if the applications is built with
threads, otherwise the library doesn't work right.
Increasingly, everything is just built with threads though.
