Following a four-month public beta period, Microsoft on Thursday released Office 2016 for Mac, now available for immediate download to existing Office 365 subscribers. The new release, strongly modeled on the existing design changes seen in the iPad version of the productivity suite, is the first new full version of Office for Mac since 2010, and adds features such as the Ribbon interface, sandboxing support, Retina screen optimization, and support for fullscreen view.
