Like any company, WhatsApp wants you to use its messaging app as much as possible. To achieve this, it is implementing features to facilitate interaction between users and their contacts. You will soon be able to see which of your contacts have been online recently.

WABetaInfo found the change in a recent WhatsApp beta for Android (2.24. 9. 14) which shows a “Recently Online” section when selecting contacts to place a call. While the list of recently online contacts will not be complete, and will only show a few contacts who have been online recently, it will still allow users to control who they can talk to without worrying about being interrupted. This should not override the privacy setting of the user’s online status.

There is also a ‘Start Chatting’ section in the main Chats section which will display the new contacts added to the user’s contact list. This will not only allow users to quickly find recently added contacts but also encourage them to start a conversation with them.

It's safe to say that once these features are available, you can expect to receive more calls and messages from users you've recently interacted with.
