In February, Microsoft announced the release of Office 2013 Service Pack 1. The only major functionality update listed in the SP1 changes appears to be “Power Map” for Excel, a “3D visualization tool for mapping, exploring, and interacting with geographical and temporal data in Excel.” This feature is listed as being available to Office 365 ProPlus customers.
Most of the other changes in SP1 provide improved compatibility with Windows 8.1, Internet Explorer 11, and newer hardware.
