Significant changes to the format of the Championship were made at GAA's Annual Congress in February 2017. The most significant change was the creation of The All-Ireland Quarter-Final Group Stage (known as the Super 8s), which replaced the previous Quarter-Final stage of the Championship. Additionally the All-Ireland Final was moved to August and replays would only be held for drawn provincial finals and drawn All-Ireland Finals, with extra time to be played in all other Championship matches. The changes were to be trialled for three years before being reviewed by the GAA in late 2020.
