Office 2016 for Mac includes redesigned versions of Word, Excel, PowerPoint, OneNote and Outlook for Mac users, and can be installed and used right alongside Office for Mac 2011 for anyone hesitant to switch entirely to pre-release software for their productivity needs. The updated software includes support for Retina displays, as well as iCloud syncing, and has a look and feel more in tune with the versions of Office currently available on Windows and mobile.
Microsoft already told us Office 2016 for Mac was coming, but the public preview is out now as a free download, without any Office 365 subscription required.
