Instant messaging (IM) service WhatsApp has launched several new features - but if you're an iPhone user, you're in for a little wait before you can start making the most of them.
At present, that's because the changes are exclusively available to Android users, with Apple device owners waiting for a future update to the platform.
The makeover for the app will see customers be able to add captions when sending documents, as well as personal avatars landing in a fun new feature.
