A player attempting to take a boundary catch must be airborne from the inside of the boundary in order to take a catch, irrespective of whether his feet touch the ground or not. This means a player can not jump from outside of the boundary, take a catch mid-air and land inside the boundary.
Like football, in cricket too, players now could be sent off for serious or violent misconduct.
Bouncing bat run outs won't be given as out considering the batsman and the bat are in "continued forward momentum through running or diving"
Fielders intentionally deceiving or distracting a batsman (for example, mock fielding where a player pretends to throw or pick up a ball) can now be penalized.
Finally, ICC is able to put a cap on the bat's thickness, with the width and the length unchanged, the thickness and depth has been limited to 40mm and 67mm respectively.
The ICC has approved the use of tethered bails i.e. bails attached to a string to prevent injuries.
In Test Cricket, the number of substitutes have increased from four to six.
Players can now be caught, stumped, or run out after the ball strikes the helmet being worn by the fielder or the wicketkeeper.
A no ball will be called if the delivery bounces more than once before reaching the crease of the batsman's end. Previously, the rule applied to more than two bounces.
A batsman can be recalled by umpires or an appeal can be withdrawn by the fielders before the next ball is bowled even if the batsman has left the field.
Bowlers who are caught deliberately bowling a no-ball would be banned from bowling for the remainder of the innings.
Handling the ball is no longer a separate dismissal, from now on, it would be counted under obstructing the field law.
If a match is shortened to less than ten overs in case of rain, the bowler's max quota of overs won't be reduced to less than two.
