Probably wouldn't hurt to just do it for all series, just so people always know what to expect. A link in the sequel back to the thread for the previous season could be useful, but not strictly necessary, especially if the seasons are separated by more than a cour anyway.
I guess there can be some small judgment calls necessary for the rare shows that change title mid-way without any break at all in broadcasting (I think Yurumates did this) but those are corner cases.
