This is according to a post on Microsoft’s website in which it reads, “Office 2019 delivers new features to help end users create amazing content in less time. Updates include new and improved inking features across the apps, like the roaming pencil case, pressure sensitivity, and tilt effects; more powerful data analysis in Excel, like new formulas, new charts, and Power BI integration; and sophisticated presentation features in PowerPoint, like Morph and Zoom. These features are already included in Office 365 ProPlus but are not available in Office 2016.”
However given that this preview is aimed more towards commercial users, Microsoft is highlighting some of the changes that might be more applicable towards such users, such as Click-to-Run which offers fast deployments and updates so that IT managers can manage updates more efficiently. There is also talk about improved security, increased productivity, and more. If you are a commercial user and would like to check out this preview, head on over to Microsoft’s website to sign up.
