The FIA release in full:
The following sporting regulations were approved for the 2007 FIA Formula One World Championship.
Practice
Teams may only use two cars in any one practice session. A nominated third driver or either race driver can use these cars in the session.
The two free practice sessions on the first day of practice have been extended from one hour to ninety minutes each.
Tyres
The single tyre supplier is required to provide identical quantities and specifications of tyres to all teams over a calendar year.
It may only provide two specifications of tyre at each Event.
The quantity of dry-weather tyres each driver may use at an Event has been increased from seven sets to 14. A maximum of four sets will be available to each driver for the first day of practice and 10 for the remainder of the Event.
Engines
The two-race engine regulations will now only apply to the second day of practice and the day of the race.
Engines homologated and used during the last two Events of 2006 must now be used during the 2007, 2008, 2009 and 2010 seasons.
Safety Car
When the Safety Car is deployed no car is permitted to enter the pits until all are bunched up behind the Safety Car. This is to remove all incentive for cars to be driven quickly back to the pits for refuelling when the Safety Car is deployed.
Before the Safety Car returns to the pits any lapped car between cars running on the lead lap must pass those cars and the safety car. It may then proceed around the track to take up position at the back of the line of cars behind the safety car.
Before a race is resumed any lapped car between cars running on the lead lap must pass those cars and the safety car and then proceed around the track to take up position at the back of the line of cars behind the safety car.
Stewards
The stewards may now impose grid place penalties.
