It "parked up" for part of the Martian winter as the amount of available sunlight was insufficient to continue roving around the Endeavour crater where Oppy is currently investigating. Although it hasn't moved all that much in the last 19 weeks it has still been returning data to Earth, but now it's on the move again and drove 3.67m on 08-MAY-2012.
It is now heading for some dust dunes (see picture from the official MER PANCAM site) north of her winter resting place.
After investigating these, Oppy may well go looking for more gypsum deposits similar to those that were discovered last year.
Interestingly, it is now only about 85 days until Curiosity is due to land on Mars. If MSL Curiosity lands successfully it will probably take a significant amount of the limelight away from Opportunity. Which will be a pity I guess. Especially when you bear in mind mind that Oppy ended her primary mission in 2004! Everything we have had since then from Oppy (and Spirit) has been a bonus. No doubt, Curiosity will move knowledge of Mars on significantly, but Opportunity will never be forgotten and, for now at any rate, she just keeps going.
