If you are a user of WhatsApp, you should see a small but useful change in the application. Indeed, the application will now turn his blue double checkmarks when a message has been read.
If read receipts do not seem new to you, you're probably not alone. Many users have misinterpreted the double-marks which is next to messages that indicate only that a message was viewed.
In fact, double-marks simply mean that a message was received by the other user. The blue color adds a third layer of information, the blue colour now indicates that the message has been read.
Alternatively, you can long press on a message screen to access a 'Message Info', specifying the times when the message was received, read or played.
Of course, you can use "Last" indicators on the upper left corner of a conversation to know when a contact has been on the application, but the blue marks are more direct. It would have been nice to have a choice, some users may not be so fond additional information.
You should begin receiving new read receipts as you have the latest version of WhatsApp for Android or iOS.
