Calendar events that update when Google Groups change

Starting today when Google Calendar invitations are sent to members of a Google Group, the attendee list will automatically update as people join or leave the group. When you join a Google Group, you will be added to all of its meetings. And if you leave a group, those meetings will be removed from your calendar. Note that groups stop dynamically changing when the total number of guests in the event crosses 200.

Domain-restricted Google+ communities

Starting today, new Google+ communities will be restricted to your domain by default if sharing is restricted in the Admin console. Posts in these communities are only viewable by people within the domain. However, you can still choose to create communities with people outside your organization so clients, agencies or business partners can join in. You can also make your community open to anyone at your domain or private, joinable by invitation only. Community owners can easily change settings, manage membership or invite other team members to join.
