A raft of changes aimed at making golf quicker and more enjoyable will be introduced from 1 January, 2019. The R&A and the United States Golf Association, the joint rules-making bodies, have also taken steps to make them easier to understand.

For the first time a 'player's edition' of the Rules of Golf has been launched and it includes diagrams and illustrations as well as more direct language to explain the complexities of the game.

"This is a pretty exciting day for us, it has been six and-a-half years in the making," David Rickman, the R&A's director of governance told BBC Sport.

"We have millions of people around the world who love this sport and want to play by the rules. We needed to step up and give them the best opportunity to do that."

Changes that come in next year were first launched for public consultation in March 2017. The authorities received more than 30,000 pieces of feedback before refining the proposals which were published on 12 March this year.

Among the alterations coming into force

• Free and penalty drops being made from knee rather than shoulder height
• The flag no longer needing to be removed from the hole for putts on the green
• Caddies not allowed to line up players before they hit shots
• No penalty for an accidental double hit

"The general tenor of these changes has been the removal of penalties, the removal of restrictions, creating a slightly more relaxed approach," Rickman said.

"There are one or two areas, and caddie lining up is perhaps the primary example, where there is a new restriction coming in 2019."

Players will also be able to access the new rulebook online and through a smartphone app. The R&A admit that previous rulebooks were difficult to understand.

"The rules were cleverly written but they were quite sophisticated and you had to know your way round them so we did spend a lot of time looking at layout and structure," Rickman added.

"This is all now very real and now the new rules are out there. The new players' edition, something we have not done before, concentrates on the most commonly occurring rules and allows us to focus on those.

"We can present them in different ways, more direct language, a lot of diagrams and illustrations which are particularly useful around relief options.

"It is also worth noting modified rules for players with disabilities. We've had these modifications in place for the best part of 20 years but we haven't promoted them as much as we perhaps should.

"We've been delighted to work with individual players and group organisations to modernise these as well and launch them at the same time."

The launch of the new rulebook comes on the same day as the R&A revealed what it calls a "playbook" outlining the governing body's "vision, purpose and values".

They aim to make golf more accessible, appealing and inclusive while upholding the sport's traditions and breaking down barriers to progress.

Investment totalling £200m is being promised to develop golf over the next decade.

"Our new brand brings together everything we have done over the last three years on ways to modernise golf and take the sport forward," said R&A chief executive Martin Slumbers.

"We have a global role to play in leading the sport, while working collaboratively with our partners and international affiliated organisations to grow and nurture golf to ensure that it continues to thrive in 50 years' time."
