This was long overdue. Following is the USGA news release.
FAR HILLS, N.J. (Dec. 8, 2016) – The USGA and The R&A today announced the introduction of a new Local Rule that eliminates the penalty when a ball is accidentally moved on the putting green. The Local Rule will be available for any committee in charge of a competition to use starting Jan. 1, 2017. It will be adopted by the USGA and The R&A in all of their championships, qualifying competitions and international matches.
"Eliminating this penalty responds to the concerns we have heard from both golfers and committees about the difficulties in applying the current Rules when a player accidentally causes a ball to move on the putting green," said Thomas Pagel, USGA senior director, Rules of Golf and Amateur Status, said.
