WhatsApp ...

Can anyone tell me if there have been updates on security of WhatsApp? I had deleted it when there was some security controversy. Need to upload it again, because our son is on tropical vacation and using it for texts.

Our family uses it, not sure if they've ever updated the security stuff.

Unfortunately, it's the cheapest way (free) to keep in touch with family overseas.
