I noticed that Whatsapp are pushing out a message that basically says the following: This version of Whatsapp will require updating in 14 days. Update to the latest version? And the two options underneath are Cancel & Upgrade. The version that this message came up with is 2.11.152. What confuses me here though is if you hit cancel then fair enough, but I clicked on the Upgrade but nowt happened, i've since re-installed my original version just incase. Apparently there is a version 2.11.181, but this hasn't hit play store yet, this it appears lets you hide last seen and profile pic for certain contacts.
