The amendments include tweaks to safety car periods and tyre usage. The FIA also revealed the Circuit Design Group is to examine Grand Prix circuits to identify the possibility of increasing overtaking opportunities.
Details from the WMSC in full:
Amendments have been made to the Sporting Regulations for immediate application:
At certain events, one additional specification of dry weather tyre may be made available to all teams for evaluation purposes. Teams will be informed about such an additional specification at least one week before the start of the relevant event. Two sets of these tyres will be allocated to each driver for use during P1 and P2, and any such tyres must be returned to the tyre supplier before the start of P3.
One additional set of prime specification tyres may be made available to all drivers. Teams will be informed about such an additional set at least one week before the start of the relevant event. In this instance, the additional set will be available for use during P1 and P2. One set of prime tyres must then be returned to the tyre supplier after P1, and two further sets of prime and one set of option specification tyres returned before the start of P3.
The safety car speed limit (an approximate 40 percent decrease in lap time) will now be enforced over two laps instead of one. The purpose is to ensure that cars are driven at a safe speed until they reach the safety car.
During a safety car period the pit exit light will remain green for the duration, unless the race is subsequently suspended.
Other than when the safety car has been asked to use the pit lane, no car may enter the pits while the safety car is deployed unless it is for the purpose of changing tyres.
