After enabling complete end-to-end encryption for chats and adding support for sending and receiving PDFs and basic text styling, WhatsApp for iPhone in its most recent update brings the ability to attach Microsoft Office documents to your instant exchanges with friends on the service.
Although not mentioned in the official release notes accompanying the 59.1-megabyte app, the change was spotted this morning by the Italian blog iSpazio. This is a useful new feature for users that removes the need to convert Microsoft Word, Excel and PowerPoint documents to the PDF format before attaching them to their WhatsApp conversations.
