The native WhatsApp camera now supports front-facing flashes, so you can take those nighttime self-portraits without turning to another app. And the Snapchat-like recording controls that made it into Instagram have spread to WhatsApp -- you can double-tap to switch between front and back cameras, and swiping up and down will zoom while you're capturing videos. You can check out all the new additions right away if you're using an Android device, and they should be coming to iOS "soon."
