The ICC has approved a number of adjustments to the playing conditions, including a modification to the powerplay regulations for men's Twenty20 Internationals. In the event that the total number of overs is reduced, the powerplay's duration will now be rounded off to the closest ball rather than the closest over.

Current rules state that in a 20-over innings, the powerplay consists of the opening six overs. In certain situations, rounding off to the closest over could make a significant difference if the innings' duration is shortened.

For instance, a shortened eight-over innings will now include 2.2 overs of powerplay with two men beyond the 30-yard circle under the new regulations, which go into effect in July. In a similar vein, a game that was formerly played with nine overs each innings will now contain 2.4 overs of powerplay. As a result, the percentage stays significantly closer to 30%.

"This table has been used in the T20 Blast in England for many years, where ending a powerplay midway through an over has caused no difficulty for players or officials. It has now been accepted by the ICC Men's Cricket Committee as the preferred method moving forward. In the eight-over example above, the umpire will make the signal after two balls of the third over, at which point three further fielders are able to drop back from within the circle,” the ICC told the members as per ESPNCricinfo.

Here is the revised table for powerplays in T20Is:
