WhatApp Official site removes the app with calling feature

WhatsApp leaked the version WhatsApp 2.11.531 on its website . But now they have removed it. This is the version that will have the most awaited calling feature. But according to tech specialists currently WhatsApp might be working on this new feature for all other platforms. Many websites have leaked screenshots from iPhone and Android phones. They might be working for Windows Phone devices and once they are ready they might release the app on all the three major Mobile Platforms. If you are using v2.11.527 you can receive the call but you can't call any number. At least till WhatsApp updates the system internally. I do have the latest APK installed on my tablet device but I think WhatsApp wants not to share the APK before they are ready with all devices. I respect their thought and so do not request me to share the APK.
