Whatsapp has rolled out update with some new features but the major enhancement we have got is the PDF File Sharing. The latest Whatsapp will now allow you to share your documents in the pdf format.
Currently this feature is available to beta users only and if you wish to use it then you have to sign up as beta ester. You can do so by joining the beta test over here and then need to uninstall and install Whatsapp from the Play Store.
As of now we can share Photos, Videos, Locations and contacts. Other major features of the WhatsApp is Calling, sharing your favourite content with your loved ones, group chat, quick connection, and offline messages.
