Facebook 推出更新，版本为 v1.7。这次更新都有颇多改动，包括贴文中可以设定私隐，亦可以 Tag 相。
In this release, we made it easier to share with who you want by improving the sharing tool to add privacy controls on posts and match your settings on the web site. We also added a lot of cool new features like Pull to Refresh and the ability to tag friends in photos, places and posts. Finally, there’s also a great new design for Profiles and Groups. Enjoy!
