The latest version of WhatsApp for mobile phones is the one that WhatsApp users are advised to update if they want to avoid having their mobile numbers logged into their account.
A WhatsApp spokesperson told CricInfo that WhatsApp for Mac and iPhone users have been updated to the latest version, which is called 220.127.116.11, which comes with a few improvements and bug fixes.
A spokesperson from Facebook also told Crikey that WhatsApp was updated to version 18.104.22.168 on Friday, and they will update to the version 9 on Monday.
The latest version is not available on the Mac App Store, although it can be downloaded from the Facebook app.
Users can upgrade from 9.4 to 9.3 on their smartphones, or vice versa.
The version number on your phone is not the one on the website.
