The WhatsApp messaging app has updated its non-beta Windows Phone client, adding the ability to back up chats to a OneDrive account. This feature was added in the beta version of WhatsApp in September.
The new version number for WhatsApp is 188.8.131.52. Besides the OneDrive chat backup, the updates adds the ability to crop a video down to 6 seconds or less and send it as a GIF file. If you notice anything else that's new or different, feel free to let us know in the comments!
