A new update has been released for Microsoft's Office apps for Windows 10, if you're an Office Insider in the Slow ring. It brings the version number to 17.8067, and it's a preview of the April, 2017 update.
The new features actually mirror the Android build that was released a week ago. Excel takes center stage, as it adds collaborative editing, which allows more than one person to work on a spreadsheet in real-time. Also, you can now open worksheets that contain ink.
For Word, Excel, and PowerPoint, you can now easily "attach hyperlinks to recent cloud-based files or websites, and create meaningful display names for people using screen readers."
Note that this build is for the UWP Office Mobile apps, so it's available on PCs as well as phones. If you want to be eligible to receive Office Insider builds on Windows 10, you'll need to have an Office 365 subscription and be on the Slow ring of the Windows Insider Program.
