Change is coming to golf in the form of new Rules of Golf (RoG) and a World Handicap System (WHS). The latter is under discussion by the R&A and the USGA.
The new RoG were implemented 1st January 2019 and the WHS will be launched in January 2020. Many of the changes are already implemented in the USA and other countries so they will be already tested.
