The most notable change is in the sending-off of a player and cautionable offences inside the penalty box.
The previous 'triple-punishment' rule meant that a player who denied a clear goal-scoring opportunity was automatically red-carded and handed a suspension, as well as giving away a penalty.
However, the law has now changed for next season, so that players committing accidental fouls, that deny a goal-scoring opportunity, are not automatically sent-off, but cautioned instead.
Announced on Thursday, the new laws also state the ball will also be able to move in any direction from kick-off, rather than only move forward.
Players who are injured by a challenge punishable by a yellow or red card can now have quick treatment on the field, rather than having to leave, which previously gave the offending team temporary numerical advantage.
IFAB announced last month their intentions to change the laws following a comprehensive, 18-month review, led by former English Premier League referee David Elleray.
The IFAB unanimously approved the revision, which they identified as a 'once in a generation' opportunity to address anomalies and inconsistences in the laws.
The IFAB, the game's law-making body, also approved a two-year trial period of video technology to assist referees, to be used in four cases: to determine if a goal has been scored, red cards, penalties and mistaken identity.
