CALIFORNIA: Facebook has unveiled its new logo, mobile app and website. Zuckerberg described the new Facebook app as the fifth major iteration of the service.

The Facebook logo will now be a circle rather than a square. The website also features much less blue, which has long been Facebook’s color.

Facebook’s new design is meant to be simpler and put “your communities” at the center. Users will begin noticing some of the new changes in the Facebook app immediately, while the new website will come in the coming months.
