Adsense Has A New Terms Of Agreement?

I signed in to my Adsense account today and found that after I logged in, it took me to their new Terms and Agreement page. I didn't know that they were going to do this and I will have to do a little searching around to see if I can find out more about why they have a new Terms and Agreement. If you know anything about this please be sure to let me (and us) know.

"Invalid Clicks - Adsense For Content"

Imagine my surprise when I looked at my Adsense details today and saw the above titled information in my account details!

I did some checking around and found some very good online articles on this subject:

Invalid Traffic Adsense For Content

and

Google Adsense Answers.
