Here’re the new features details from AdSense blog post:
- You can now view the ID number associated with a specific custom channel by visiting the 'Channels' link under the 'AdSense Setup' tab. Many of you told us that you needed these channel ID numbers for ad management programs you're using. We've added this information to your account since it no longer appears in your ad code.
- Any ad units generated within the last 7 days that haven't yet received any impressions will now be listed as 'New', rather than 'Active', in your status column. This should help avoid confusion about your newest ad units and those already appearing on your pages.
- You can now view the most recent date when each of your ad units was updated. Please note that these dates aren't retroactive, so any ad units you generated or edited before this display change will show a last-edited date of November 1st, 2007.
- We're starting to slowly roll out the manage ads feature for your referral units. Just as with AdSense for content units, you'll soon be prompted to enter names for your newly generated referral units. If you'd like to make changes to your referral units at a later time, you can visit the 'Manage Ads' page. In the 'Content' column of this page, your referral units will display 'Referrals:' followed by the products or category of products being referred.
