Enterprise support and controls for the new Hangouts

Summary of Changes

Finding the people you need to communicate with is easier. Users can now search within the GAL right from the friend list in Hangouts and see contacts that are more relevant to them.
Hangouts is now supported by the Google Apps support team, just like Talk or any other core service.
Administrators have new controls over how chats are used within their domain:

Sharing: Allow users to chat outside the domain
Invitation Auto-Accept: Set invitations to automatically accept between users in your domain
Voice and Video: Allow users to make voice and video calls from Hangouts, including voice calls to phone numbers
History: Set conversation history to default on or off

Things to Note

Regardless of the setting in the admin console, users can turn history on or off for any hangout.
If external sharing is allowed, users will not see a warning when they begin a Hangout with users outside of their domain.
