For those of you who felt restricted with the AdSense limit of 10 channels, Google has not increased that number to 60. In addition, they have launched 5 additional languages that they support. The biggest announcement is the ability to set up channels the lazy man way, URL based. So now you can "track individual pages, or to track groups of pages based on the directory structure of your site."
For more information see the AdSense Support documentation on How do I create URL channels? and also check out the WebmasterWorld thread.
