According to the history of the Fraternity stated on their official website, the Charlotte Grand Conclave in 1968 mandated a constitutional convention for the revision of the Fraternity’s constitution and by-laws as well as the Ritual. That convention was held in Atlanta in 1969.
The revised Constitution and By-Laws and the Ritual went into effect at the close of the 1970 Pittsburgh Grand Conclave.
As it turns out, there are no references found on the places that still may practice the old version of the ritual for Omega Psi Phi Fraternity. You can download a copy of the Omega Psi Phi ritual book here.
