The big news is that Voyager 2 should be experiencing more interstellar medium than atmosphere from our star at this point. It will still be a while before it could be said to truly "leave the Solar System" if you consider gravitational influence to be a factor. There are objects still orbiting our star at more than a light year away for example (Oort cloud).
