Officially, the new version number for WhatsApp on Windows Phone is 2.12.212. A couple of our readers have indicated that there is a new user interface for the camera and starred message support in this new version but we have been unable to confirm this. If you do notice these changes, and any others with the new WhatsApp update, please let us know in the comments and we will update the post.
Thanks to everyone who tipped us!
