Whatsapp seems to be serious about Windows Phone platform. Recently company announced support for documents sharing on Android beta program. Now the company has pushed an update to the Whatsapp beta app for Windows Phone devices as well.
Now the version has been moved to 2.12.310 & it lets you share documents file from within the app & in the chat screen. Currently it supports sharing of PDF files only. Microsoft Word or Excel files are not allowed to share in the current version.
When you tap on the attach option, it gives you a new menu where you can see that ‘Documents’ has been added. But the company hasn’t got any icon for documents . Maybe the icon will come in next beta update for Whatsapp.
