Skype fixes security loophole

According to Skype:

"We have recently introduced the ability to hide a Skype user's IP address, and we've set this as a default status in the latest versions of Skype."

Up 'til now your IP address was visible to the other person and that gave them -or a hacker- the potential to track your location, or even to start a "denial of service" attack against your PC.
