The IRB have issued a number of experimental law changes for the forthcoming season details of all laws can be seen here:
There are 2 in particular that will affect our rugby next season.
1) Law 16 : Ruck
16.7 Unsuccessful end to a ruck.
Five seconds to play the ball from the back of the ruck.
Add new 16.7(c):
When the ball has been clearly won by a team at a ruck and the ball is available to be played the referee will call "Use it!" after which the ball must be played within five seconds. If the ball is not played within the five seconds the referee will award a scrum and the team not in possession of the ball at the ruck is awarded the throw in.
2) Law 20 : Scrum
20.1 Forming a scrum.
Changed scrum engagement sequence.
The referee will call "crouch" then "touch". The front rows crouch and using their outside arm; each prop touches the point of the opposing prop's outside shoulder. The props then withdraw their arms. The referee will then call "set" when the front rows are ready. The front rows may then engage. The "set" call is not a command but an indication that the front rows may come together when ready.
