I always wonder exactly what has been added when the red message comes up announcing that new changes are available (sometimes it takes weeks for me to figure out what's new). This appears to be one of them. I would think webmasters will find this more friendly than the past approach to policy violation notices but, it may also signal a crackdown in the works. More tools for notifying you of policy violations = more policy violation notices. That's my guess. Hang on!
