Feb.2 (GMM) Even more rules changes may be adopted prior to the start of the 2010 season.
Following Monday's meeting of the F1 Commission in Paris, the FIA confirmed the reported tweaks to the points system and the reduced tyre allocation.
"Further measures for 2010 are also being examined," read a media statement.
The meeting also approved the controversial move to require the top ten qualifiers to race with their Q3 tyres, with all rule changes needing to now be approved by the World Motor Sport Council.
Double diffusers were also banned for 2011.
