- Putting with flagstick left in the hole: There is no longer a penalty if you play a ball from the putting green and it hits the unattended flagstick in the hole.
- Repairing damage on the putting green: You may repair almost all damage (including spike marks and animal damage) on the putting green (rather than being limited to repairing only ball-marks or old hole plugs).
- Touching your line of putt or touching the putting green in pointing out target: There is no longer a penalty if you or your caddie does either of these things, so long as doing so does not improve the conditions affecting your stroke.
- Replacing your ball if it moves only after you had already marked, lifted and replaced it: Anytime this happens on the putting green, you replace the ball on its spot – even if it was blown by the wind or moved for no clear reason.
- Your caddie marks and lifts your ball on the putting green: There is no longer a penalty if your caddie does this without your specific authorisation to do so.
