Although I think they are exaggerating in Findmypast Fridays by saying they have "millions of new parish registers"! I assume they mean millions of parish register entries.
Scotland Parish Births & Baptisms 1564-1929
Scotland Parish Marriages & Banns 1561-1893
Scotland Parish Deaths & Burials 1564-2017
I am so glad to see they have transcribed parish registers from after the start of civil registration. For so long, online sources excluded these.
