The Austrian Staatsbürgerschaftsgesetz 1985 sounds a bit out of date, does it really still apply?

The Staatsbürgerschaftsgesetz 1985 related to the fact that the recasting of the Austrian Citizenship Act took place in 1985. It has been amended on many occasions since then, with Articles and paras. than no longer apply being repealed or amended accordingly. Similarly the same has happened to the British Nationality Act of 1981.
