We’re releasing three features to make it even easier to get things done with Google+:
1. Domain labels in the mobile apps and on the web help you quickly identify coworkers’ profiles.
2. The Google+ Android app now lets you create restricted posts, limited to your domain, as well as log in to and switch between multiple accounts.
3. The new Google+ Domains API allows Apps customers and resellers to integrate Google+ into their existing tools and processes to streamline tasks such as creating posts, commenting and managing circles.
