AdSense Updates

Old AdSense accounts migrates to Google Account
According to Inside AdSense, Google will be migrating old AdSense accounts to Google Account and targeted users would be greeted by a screen like the one below, asking them to upgrade their login to a "Google Account".

Existing users who signed up for AdSense using their Google Account would not see this message yet the AdSense team is working to make this possible.

AdSense homepage update
AdSense has updated their homepage so that it looks more AdWords like. The basic contents are about the same compared to the old layout yet you will see a more attractive 'Sign up now' button right above the log in box.
