Shared items in your Google Docs account evolve as the people you collaborate with make edits and share new items with you. Google Docs now shows “visual indicators” to make it easier to spot what's changed and what's been newly shared with you. The names of files that’ve been edited since you lasted opened them’e in bold, and shared files that you haven't opened yet have a red 'New!' tag.
Also, Administrator controls for Chat helps companies and schools using Google Apps to limit how their users communicate with Google Talk and Gmail Chat. This new option is found in the Chat service settings area of the Premier and Education Edition control panels.
