Direction does not have to change when velocity is changed. You can move North at 10 m/s and change it to 8 m/s a second later. You would still be moving North. But since velocity is a vector, if direction changes, even though speed (magnitude of velocity) remains constant, then velocity most certainly changed, since both magnitude and direction make up the vector.
