According to a resolution adopted on Monday, players who missed more than 52 weeks will be given three years of protection by receiving a special ranking for their first 12 tournaments after their return.
The change did not result in what happened to Serena Williams this year, as the 23-year-old Grand Slam-winning American star returning after childbirth was not featured on Roland Garros because of a long skipping down to 451 in the world rankings.
The WTA management has also modernized the dress code and introduces in major tournaments that it can take up to 25 seconds between two games, and in 2020 it will be used in all tournaments to speed up the game.
It is also a change that players can go to the toilet only once during the match instead of two.
