Thank you for your answer. Yes you can do the color rating in Bridge. However it was possible until now to do it also in Camera Raw with the shortcuts (ctrl+6, ...). Sadly it seems that they removed this feature with the new version.
Seems that this update wasn't very well thought out. Your choice is to go back to the previous version or tough it out until the update/fix is released. I don't work for Adobe and have no information to provide. Sorry.
