Yes, this is old. Do you live under a rock, OP?
The Church of Greece restored the female diaconate in 2004 too, I believe.
As for the office itself, it was sometimes understood as a minor order (see the Council of Nicea's canon 19) and sometimes as a major order equal to that of male deacons (see the Council in Trullo's canon 14).
