New feature is as simple as it sounds: it allows users to delete sent messages. However, you've been able to remove the messages from your app even before but now the messages can be removed from even the recipients devices.
The new delete function can be found within the post editing tools. Now when you long press the message and select the delete function (the trashcan icon) you'll be hit with a dialog asking whether you want it deleted from all devices or your device only. Previously you didn't have the former option.
There are some limitations, obviously. You can only delete – or perhaps cancelling would be a more apt term – messages from all devices if they've been sent within seven minutes. After that you'll only be able to remove the post from your own apps.
Also to not confuse people, WhatsApp replaces the message with one saying the original message has been deleted.
The feature will hit your iPhone or Android device in the coming weeks so you might not have the update yet on your mobile device.
