An anonymous reader writes: WhatsApp 3.0 will come with two privacy-related changes. The first is in the Security section and is in the form of a new setting called "Show security indicators." Turning on this setting will add a lock icon to your WhatsApp whenever you're having encrypted conversations. The second new setting is in the Account section, with the addition of a new option that says "Share my account info." This setting will send the user's WhatsApp data to Facebook servers "to improve [their] Facebook experiences."
