With more than a billion users now, WhatsApp, the world's most popular instant messaging platform, has slowly been turning from a barebones chat app, into a more sophisticated endeavor that is almost (but not quite) on par with the best out there in terms of features.
Just recently it added rich link previews, like on Facebook Messenger or Viber, the ability to star messages to its Android app, a bunch of Unicode emojis, and, above all, removed its funny $1 annual subscription fee. Some of these features have been in the beta versions you can download only from WhatsApp's own site first, and then, as usual, got rolled into the official app update over at the app stores.
The latest in these WhatsApp beta installments is the 2.12.489 version, which in its turn brings even more goodies to the platform. Apart from link copying (previously you had to snag the whole chat) and more granular chat clearance, with added options to delete chats older than 30 days or 6 months, you will get the the ability to send documents.
Yep, you read that right, WhatsApp is finally getting around to doc exchange, though at the moment you can only send PDF files, and even that is seemingly no-go for iOS users, but the feature is present in the Android beta. Grab the latest 2.12.489 beta APK from the source link below, and sideload it on your Android handset if you are interested in the new goods.
