New Delhi | Jagran Technology Desk: Facebook-owned Whatsapp has announced the release of a spree of new features on its beta app non-Apple's iPhone. Along with some generic bug improvements, and neutralisations, Whatsapp will stimulate some voice over improvements in its iOS version, although the biggest highlight remains the Contacts Shortcut feature. The bubble colour of its messenger's interface has also been changed slightly to a different shade of green, for a change to those who wanted and even demanded changes on iTunes for Whatsapp's Dark feature.
