Hallelujah! The WGA has approved the agreement reached to end the strike, and while it still must be ratified by the members, showrunners and writers can return to work tomorrow (February 11). This means that Shonda can begin to start cranking out new episodes of Grey's and Private Practice. This is AWESOME news and means that the strike is OFFICIALLY OVER! From TVGuide.com:

The boards for both branches of the Writers Guild of America on Sunday unanimously approved the tentative deal reached on a new contract. The boards are also taking the final decision on liftng the strike to membership in a vote on Tuesday.

In the meantime, showrunners will get going even sooner, heading back to work Monday to get crews set up and production facilities going again, as will writers who have producing duties on their shows. Ballots to ratify the three-year deal are also going out to members, and will be returned within a 10-12 day period.
