The Google AdSense team introduced a Known Issues page, which you can find here,

On that note, we'd like to let you know about the new Known Issues page, where you can check for updates on this reporting issue and other existing issues. There can be occasional hiccups in our system, but we hope that this new resource will help increase transparency and keep you informed.

Also on the Google Talk blog new styles are anounced for Google Talk Chatback.
